  • Question 1 - Which drug is classified as a schedule 2 controlled substance? ...

    Correct

    • Which drug is classified as a schedule 2 controlled substance?

      Your Answer: Methylphenidate

      Explanation:

      Schedule 2 drugs are medications that necessitate a prescription for controlled substances and must be recorded in a drug register for medical purposes.

      Drug Misuse (Law and Scheduling)

      The Misuse of Drugs Act (1971) regulates the possession and supply of drugs, classifying them into three categories: A, B, and C. The maximum penalty for possession varies depending on the class of drug, with Class A drugs carrying a maximum sentence of 7 years.

      The Misuse of Drugs Regulations 2001 further categorizes controlled drugs into five schedules. Schedule 1 drugs are considered to have no therapeutic value and cannot be lawfully possessed of prescribed, while Schedule 2 drugs are available for medical use but require a controlled drug prescription. Schedule 3, 4, and 5 drugs have varying levels of restrictions and requirements.

      It is important to note that a single drug can have multiple scheduling statuses, depending on factors such as strength and route of administration. For example, morphine and codeine can be either Schedule 2 of Schedule 5.

      Overall, the Misuse of Drugs Act and Regulations aim to regulate and control the use of drugs in the UK, with the goal of reducing drug misuse and related harm.

    Correct

    • A young woman in her twenties presents to the A&E department with complaints of abdominal cramps. Upon examination, you observe goose bumps all over her skin and dilated pupils. Which drug withdrawal is she most likely experiencing?

      Your Answer: Heroin

      Explanation:

      Illicit drugs, also known as illegal drugs, are substances that are prohibited by law and can have harmful effects on the body and mind. Some of the most commonly used illicit drugs in the UK include opioids, amphetamines, cocaine, MDMA (ecstasy), cannabis, and hallucinogens.

      Opioids, such as heroin, are highly addictive and can cause euphoria, drowsiness, constipation, and respiratory depression. Withdrawal symptoms may include piloerection, insomnia, restlessness, dilated pupils, yawning, sweating, and abdominal cramps.

      Amphetamines and cocaine are stimulants that can increase energy, cause insomnia, hyperactivity, euphoria, and paranoia. Withdrawal symptoms may include hypersomnia, hyperphagia, depression, irritability, agitation, vivid dreams, and increased appetite.

      MDMA, also known as ecstasy, can cause increased energy, sweating, jaw clenching, euphoria, enhanced sociability, and increased response to touch. Withdrawal symptoms may include depression, insomnia, depersonalisation, and derealisation.

      Cannabis, also known as marijuana of weed, can cause relaxation, intensified sensory experience, paranoia, anxiety, and injected conjunctiva. Withdrawal symptoms may include insomnia, reduced appetite, and irritability.

      Hallucinogens, such as LSD, can cause perceptual changes, pupillary dilation, tachycardia, sweating, palpitations, tremors, and incoordination. There is no recognised withdrawal syndrome for hallucinogens.

      Ketamine, also known as Vitamin K, Super K, Special K, of donkey dust, can cause euphoria, dissociation, ataxia, and hallucinations. There is no recognised withdrawal syndrome for ketamine.

    Correct

    • Which of the following is not a symptom commonly linked to alcohol intoxication?

      Your Answer: Hyperreflexia

      Explanation:

      Alcohol intoxication typically results in a decrease in reflexes and an increase in reaction times.

      Alcohol Intoxication

      Symptoms of moderate alcohol intoxication can include a range of effects on the body and mind. These may include poor concentration, impaired reaction times, conjunctival injection, pinpoint pupils, poor coordination, memory difficulties, impaired judgement, and impaired sense of time and space. It is important to be aware of these symptoms and to avoid driving of operating heavy machinery while under the influence of alcohol.

  • Question 4 - Which receptor is typically targeted by drugs used for managing alcohol withdrawal? ...

    Correct

    • Which receptor is typically targeted by drugs used for managing alcohol withdrawal?

      Your Answer: GABA receptors

      Explanation:

      Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days. Withdrawal seizures may occur before blood alcohol levels reach zero, and a small percentage of people may experience delirium tremens (DT), which can be fatal if left untreated. Risk factors for DT include abnormal liver function, old age, severity of withdrawal symptoms, concurrent medical illness, heavy alcohol use, self-detox, previous history of DT, low potassium, low magnesium, and thiamine deficiency.

      Pharmacologically assisted detox is often necessary for those who regularly consume more than 15 units of alcohol per day, and inpatient detox may be needed for those who regularly consume more than 30 units per day. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess the severity of withdrawal symptoms and guide treatment decisions. Benzodiazepines are the mainstay of treatment, as chronic alcohol exposure results in decreased overall brain excitability and compensatory decrease of GABA-A neuroreceptor response to GABA. Chlordiazepoxide is a good first-line agent, while oxazepam, temazepam, and lorazepam are useful in patients with liver disease. Clomethiazole is effective but carries a high risk of respiratory depression and is not recommended. Thiamine should be offered to prevent Wernicke’s encephalopathy, and long-acting benzodiazepines can be used as prophylaxis for withdrawal seizures. Haloperidol is the treatment of choice if an antipsychotic is required.

  • Question 5 - What is a true statement about opioid withdrawal? ...

    Correct

    • What is a true statement about opioid withdrawal?

      Your Answer: Withdrawal symptoms may develop upon abrupt discontinuation of opioids after 5 days of regular and uninterrupted opioid use

      Explanation:

      The fact that even brief periods of opiate use can lead to withdrawal symptoms highlights the addictive nature of these drugs.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days. Buprenorphine withdrawal lasts up to 10 days and includes symptoms like myalgia, anxiety, and increased drug craving.

      Opioids affect the brain through opioid receptors, with the µ receptor being the main target for opioids. Dopaminergic cells in the ventral tegmental area produce dopamine, which is released into the nucleus accumbens upon stimulation of µ receptors, producing euphoria and reward. With repeat opioid exposure, µ receptors become less responsive, causing dysphoria and drug craving.

      Methadone and buprenorphine are maintenance-oriented treatments for opioid dependence. Methadone is a full agonist targeting µ receptors, while buprenorphine is a partial agonist targeting µ receptors and a partial k agonist of functional antagonist. Naloxone and naltrexone are antagonists targeting all opioid receptors.

      Methadone is preferred over buprenorphine for detoxification, and ultra-rapid detoxification should not be offered. Lofexidine may be considered for mild of uncertain dependence. Clonidine and dihydrocodeine should not be used routinely in opioid detoxification. The duration of detoxification should be up to 4 weeks in an inpatient setting and up to 12 weeks in a community setting.

      Pregnant women dependent on opioids should use opioid maintenance treatment rather than attempt detoxification. Methadone is preferred over buprenorphine, and transfer to buprenorphine during pregnancy is not advised. Detoxification should only be considered if appropriate for the women’s wishes, circumstances, and ability to cope. Methadone or buprenorphine treatment is not a contraindication to breastfeeding.

    Correct

    • What factor is most likely to lead to an incorrect positive outcome when screening for amphetamine use?

      Your Answer: Bupropion

      Explanation:

      Drug Testing

      There are two main approaches to testing for illicit substances: immunoassays and lab testing. Immunoassays are a cheap and quick screening method, but not very specific. Lab testing is more accurate but time-consuming and expensive. Drug testing can be done through urine, saliva, blood, hair, and sweat, although hair and sweat are rarely used in mental health settings.

      False positives can occur when testing for illicit substances, so it’s important to check that patients are not taking other medications that could produce a false positive result. For example, common medications that can lead to false positive results include dimethylamylamine, ofloxacin, bupropion, phenothiazines, trazodone, and methylphenidate for amphetamines/methamphetamines; sertraline and efavirenz for benzodiazepines and cannabis; topical anesthetics for cocaine; codeine, dihydrocodeine, and methadone for opioids; lamotrigine, tramadol, and venlafaxine for PCP; and amitriptyline, bupropion, buspirone, chlorpromazine, fluoxetine, sertraline, and verapamil for LSD.

      In summary, drug testing is an important tool in mental health settings, but it’s crucial to consider potential false positives and medication interactions when interpreting results.

      Your Answer: Enhanced sociability

      Correct Answer: Tachycardia

      Explanation:

      Illicit drugs, also known as illegal drugs, are substances that are prohibited by law and can have harmful effects on the body and mind. Some of the most commonly used illicit drugs in the UK include opioids, amphetamines, cocaine, MDMA (ecstasy), cannabis, and hallucinogens.

  • Question 8 - What type of amnesia is typically associated with Korsakoff's syndrome? ...

    Incorrect

    • What type of amnesia is typically associated with Korsakoff's syndrome?

      Your Answer: Retrograde amnesia

      Correct Answer: Anterograde amnesia

      Explanation:

      Korsakoff’s syndrome is characterized by a significant and disproportionate loss of the ability to form new memories, known as anterograde amnesia, in an otherwise cognitively intact individual (Caulo 2005). Additionally, individuals with this syndrome may experience source amnesia, where they can recall information but cannot remember where of how they learned it, as well as prosopamnesia, which is the inability to recognize of remember faces.

      Korsakoff’s Syndrome

      Korsakoff’s Syndrome, also known as amnesic syndrome, is a chronic condition that affects recent and anterograde memory in an alert and responsive patient. It is caused by prolonged thiamine (vitamin B1) deficiency and often follows Wernicke’s encephalopathy. The syndrome is characterized by a lack of insight, apathy, and confabulation. Thiamine is essential for glucose metabolism in the brain, and its deficiency leads to a toxic buildup of glucose, causing neuronal loss. The Mammillary bodies are the main areas affected in Korsakoff’s syndrome.

      While intelligence on the WAIS is preserved, episodic memory is severely affected in Korsakoff’s syndrome. Semantic memory is variably affected, but implicit aspects of memory, such as response to priming and procedural memory, are preserved. Immediate memory tested with the digit span is normal, but information can only be retained for a few minutes at most. Patients with Korsakoff’s syndrome often display apathy, lack of initiative, and profound lack of insight.

      Your Answer: Atomoxetine

      Correct Answer: Co-codamol

      Explanation:

      Co-codamol falls under the category of schedule 5 drugs.

      Drug Misuse (Law and Scheduling)

      The Misuse of Drugs Act (1971) regulates the possession and supply of drugs, classifying them into three categories: A, B, and C. The maximum penalty for possession varies depending on the class of drug, with Class A drugs carrying a maximum sentence of 7 years.

    Correct

    • A 60-year-old woman is brought to the Emergency department after being found collapsed at home. She is a retired teacher. She has been on oral anticoagulants for some weeks after suffering a pulmonary embolism.

      On assessment, you find her to be febrile, tachycardic and in need of supplemental oxygen. Her pupils are highly constricted.

      What is the most appropriate next step in managing this patient?

      Your Answer: Refer for an urgent CT scan of brain and management in intensive care

      Explanation:

      If a patient presents with pinpoint pupils, it may indicate an opioid overdose. However, if hyperthermia and tachycardia are also present, a pontine hemorrhage is a more probable cause. In such cases, intensive care management with input from neurology/neurosurgery is necessary. It is important to note that the use of injectable low molecular weight heparin (commonly used for treating deep vein thrombosis) and a high-stress job could increase the risk of an intracranial bleed.

    Correct

    • What is a distinguishing trait of being intoxicated with phencyclidine?

      Your Answer: Analgesia

      Explanation:

      PCP Intoxication: A Dangerous Hallucinogenic

      Phencyclidine (PCP), also known as angel dust, is a hallucinogenic drug that is popular for inducing feelings of euphoria, superhuman strength, and social and sexual prowess. It is a NMDA receptor antagonist that has dissociative properties, similar to ketamine. PCP was previously used as an anesthetic and animal tranquilizer, but was soon recalled due to its adverse effects, including psychosis, agitation, and dysphoria post-operatively.

      PCP is available in various forms, including white crystalline powder, tablets, crystals, and liquid. It can be snorted, smoked, ingested, of injected intravenously or subcutaneously. People who have taken PCP often present with violent behavior, nystagmus, tachycardia, hypertension, anesthesia, and analgesia. Other symptoms include impaired motor function, hallucinations, delusions, and paranoia.

      PCP intoxication is best managed with benzodiazepines along with supportive measures for breathing and circulation. Antipsychotics are not recommended as they can amplify PCP-induced hyperthermia, dystonic reactions, and lower the seizure threshold. However, haloperidol may be useful for treating PCP-induced psychosis in patients who are not hyperthermic. Most deaths in PCP-intoxicated patients result from violent behavior rather than direct effects of the drug.

    Correct

    • A 55-year-old male is admitted with fatigue, nausea and weight loss. He has a history of heavy alcohol use and has experienced delirium tremens in the past. He has abstained from alcohol for the past two days.
      During examination, he appears thin, alert and oriented. He displays signs of chronic liver disease, but there is no evidence of a flapping tremor. His pulse is regular at 88 bpm, his blood pressure is 106/74 mmHg, and his temperature is 37°C.
      What medication would be recommended for preventing acute alcohol withdrawal in this patient?

      Your Answer: Oral lorazepam

      Explanation:

      This patient, who exhibits signs of chronic liver disease due to alcohol consumption, is at high risk of experiencing acute alcohol withdrawal, especially considering her history of delirium tremens. To prevent this, benzodiazepines are appropriate agents, with oral medications like lorazepam and diazepam being recommended. While benzodiazepines can cause hepatic encephalopathy in patients with liver cirrhosis, it is not yet known if this patient has cirrhosis, and the risk of alcohol withdrawal is significant. Therefore, she should be given benzodiazepines and closely monitored for any signs of encephalopathy. In cases of hepatic impairment, benzodiazepines with a shorter half-life, such as lorazepam and oxazepam, are preferred.

    Incorrect

    • A client successfully completed a detoxification regime for her alcohol dependence 4 weeks ago and has still not consumed alcohol. According to the stages of change model, which of the following stages is she currently at?

      Your Answer: Maintenance

      Correct Answer: Action

      Explanation:

      Stages of Change Model

      Prochaska and DiClemente’s Stages of Change Model identifies five stages that individuals go through when making a change. The first stage is pre-contemplation, where the individual is not considering change. There are different types of precontemplators, including those who lack knowledge about the problem, those who are afraid of losing control, those who feel hopeless, and those who rationalize their behavior.

      The second stage is contemplation, where the individual is ambivalent about change and is sitting on the fence. The third stage is preparation, where the individual has some experience with change and is trying to change, testing the waters. The fourth stage is action, where the individual has started to introduce change, and the behavior is defined as action during the first six months of change.

      The final stage is maintenance, where the individual is involved in ongoing efforts to maintain change. Action becomes maintenance once six months have elapsed. Understanding these stages can help individuals and professionals in supporting behavior change.

  • Question 15 - What is a true statement about buprenorphine? ...

    Incorrect

    • What is a true statement about buprenorphine?

      Your Answer: Buprenorphine has consistently been shown to be more effective than methadone at preventing relapse

      Correct Answer: Buprenorphine reduces the effect of additional opioids

      Explanation:

      Higher doses of naloxone are required to displace buprenorphine due to its strong affinity for opioid receptors, which can also result in a blocking effect and precipitated withdrawal if a patient is still using heroin.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days. Buprenorphine withdrawal lasts up to 10 days and includes symptoms like myalgia, anxiety, and increased drug craving.

      Opioids affect the brain through opioid receptors, with the µ receptor being the main target for opioids. Dopaminergic cells in the ventral tegmental area produce dopamine, which is released into the nucleus accumbens upon stimulation of µ receptors, producing euphoria and reward. With repeat opioid exposure, µ receptors become less responsive, causing dysphoria and drug craving.

      Methadone and buprenorphine are maintenance-oriented treatments for opioid dependence. Methadone is a full agonist targeting µ receptors, while buprenorphine is a partial agonist targeting µ receptors and a partial k agonist of functional antagonist. Naloxone and naltrexone are antagonists targeting all opioid receptors.

      Methadone is preferred over buprenorphine for detoxification, and ultra-rapid detoxification should not be offered. Lofexidine may be considered for mild of uncertain dependence. Clonidine and dihydrocodeine should not be used routinely in opioid detoxification. The duration of detoxification should be up to 4 weeks in an inpatient setting and up to 12 weeks in a community setting.

      Pregnant women dependent on opioids should use opioid maintenance treatment rather than attempt detoxification. Methadone is preferred over buprenorphine, and transfer to buprenorphine during pregnancy is not advised. Detoxification should only be considered if appropriate for the women’s wishes, circumstances, and ability to cope. Methadone or buprenorphine treatment is not a contraindication to breastfeeding.

    Correct

    • What is a known factor that can lead to inaccurate positive results for amphetamine on drug screening tests?

      Your Answer: Pseudoephedrine

      Explanation:

      Pseudoephedrine belongs to the phenethylamine and amphetamine chemical classes and acts as a sympathomimetic drug. Its primary purpose is to alleviate nasal and sinus congestion.

      Drug Screening

      Drug testing can be conducted through various methods, but urinalysis is the most common. Urine drug tests can be either screening of confirmatory. Screening tests use enzymatic immunoassays to detect drug metabolites of classes of drug metabolites in the urine. However, these tests have limitations, such as false positives due to cross-reactivity. Therefore, any positive test should be confirmed through gas chromatography of mass spectrometry.

      People may try to manipulate drug testing procedures by adulterating the sample. Normal urine parameters, such as temperature, specific gravity, and pH, can assist in detecting adulterated samples. Adulterants include household items like vinegar, detergent, and ammonia, as well as commercially available products. Diluted urine may also yield false negatives.

      Detection times vary from person to person, and the approximate drug detection time in urine can be found in a table provided by Nelson (2016). False positives can occur due to cross-reactivity, as illustrated by Moeller (2017). Clinicians should be aware of the limitations of urine drug tests and the potential for manipulation.

      Correct Answer: Ultra-rapid detoxification is associated with serious adverse events

      Explanation:

  • Question 18 - What is the relationship between cannabis use and the likelihood of developing schizophrenia?...

    Correct

    • What is the relationship between cannabis use and the likelihood of developing schizophrenia?

      Your Answer: The younger a person starts using cannabis the higher their subsequent risk

      Explanation:

      Consistent evidence suggests a link between cannabis use and schizophrenia risk, with the risk increasing as the age of first use decreases.

      Schizophrenia and Cannabis Use

      The relationship between cannabis use and the risk of developing schizophrenia is a topic of ongoing debate. However, research suggests that cannabis use may increase the risk of later schizophrenia of schizophreniform disorder by two-fold (Arseneault, 2004). The risk of developing schizophrenia appears to be higher in individuals who start using cannabis at a younger age. For instance, regular cannabis smokers at the age of 15 are 4.5 times more likely to develop schizophrenia at the age of 26, compared to those who did not report regular use until age 18 (Murray, 2004).

      A systematic review published in the Lancet in 2007 found that the lifetime risk of developing psychosis increased by 40% in individuals who had ever used cannabis (Moore, 2007). Another meta-analysis reported that the age at onset of psychosis was 2.70 years younger in cannabis users than in non-users (Large, 2011). These findings suggest that cannabis use may have a significant impact on the development of schizophrenia and related disorders.

    • What drug is classified as a schedule 3 controlled substance?

      Your Answer: Lorazepam

      Correct Answer: Temazepam

      Explanation:

      Temazepam falls under the category of drugs classified as schedule 3.

      Drug Misuse (Law and Scheduling)

      The Misuse of Drugs Act (1971) regulates the possession and supply of drugs, classifying them into three categories: A, B, and C. The maximum penalty for possession varies depending on the class of drug, with Class A drugs carrying a maximum sentence of 7 years.

      The Misuse of Drugs Regulations 2001 further categorizes controlled drugs into five schedules. Schedule 1 drugs are considered to have no therapeutic value and cannot be lawfully possessed of prescribed, while Schedule 2 drugs are available for medical use but require a controlled drug prescription. Schedule 3, 4, and 5 drugs have varying levels of restrictions and requirements.

      It is important to note that a single drug can have multiple scheduling statuses, depending on factors such as strength and route of administration. For example, morphine and codeine can be either Schedule 2 of Schedule 5.

      Overall, the Misuse of Drugs Act and Regulations aim to regulate and control the use of drugs in the UK, with the goal of reducing drug misuse and related harm.

    • In which psychological therapy is the concept of 'rolling with resistance' utilized?

      Your Answer: Motivational interviewing

      Explanation:

      Motivational Interviewing: A Model for Resolving Ambivalence and Facilitating Change

      Motivational interviewing (MI) is an evidence-based method used for people with substance misuse problems. It was introduced by William Miller in 1983, based on his experience with alcoholics. MI focuses on exploring and resolving ambivalence and centres on the motivational process that facilitates change. It is based on three key elements: collaboration, evocation, and autonomy.

      There are four principles of MI: expressing empathy, supporting self-efficacy, rolling with resistance, and developing discrepancy. MI involves the use of micro-counseling skills called OARS, which stands for open-ended questions, affirmations, reflections, and summaries.

      Change talk is defined as statements by the client that reveal consideration of, motivation for, of commitment to change. In MI, the therapist aims to guide the client to expression of change talk. Types of change talk can be remembered by the mnemonic DARN-CAT, which stands for desire, ability, reason, need, commitment, activation, and taking steps.

      Overall, MI is a model for resolving ambivalence and facilitating change that emphasizes collaboration, evocation, and autonomy. It is a useful tool for therapists working with clients with substance misuse problems.

    Correct

    • What is the most probable cause of withdrawal symptoms in an opioid-dependent patient who has not completed their detox program when starting a particular medication?

      Your Answer: Buprenorphine

      Explanation:

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days. Buprenorphine withdrawal lasts up to 10 days and includes symptoms like myalgia, anxiety, and increased drug craving.

      Opioids affect the brain through opioid receptors, with the µ receptor being the main target for opioids. Dopaminergic cells in the ventral tegmental area produce dopamine, which is released into the nucleus accumbens upon stimulation of µ receptors, producing euphoria and reward. With repeat opioid exposure, µ receptors become less responsive, causing dysphoria and drug craving.

      Methadone and buprenorphine are maintenance-oriented treatments for opioid dependence. Methadone is a full agonist targeting µ receptors, while buprenorphine is a partial agonist targeting µ receptors and a partial k agonist of functional antagonist. Naloxone and naltrexone are antagonists targeting all opioid receptors.

      Methadone is preferred over buprenorphine for detoxification, and ultra-rapid detoxification should not be offered. Lofexidine may be considered for mild of uncertain dependence. Clonidine and dihydrocodeine should not be used routinely in opioid detoxification. The duration of detoxification should be up to 4 weeks in an inpatient setting and up to 12 weeks in a community setting.

      Pregnant women dependent on opioids should use opioid maintenance treatment rather than attempt detoxification. Methadone is preferred over buprenorphine, and transfer to buprenorphine during pregnancy is not advised. Detoxification should only be considered if appropriate for the women’s wishes, circumstances, and ability to cope. Methadone or buprenorphine treatment is not a contraindication to breastfeeding.

    Incorrect

    • What is typically avoided during alcohol withdrawal because of the increased likelihood of respiratory depression?

      Your Answer: Diazepam

      Correct Answer: Clomethiazole

      Explanation:

      Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days. Withdrawal seizures may occur before blood alcohol levels reach zero, and a small percentage of people may experience delirium tremens (DT), which can be fatal if left untreated. Risk factors for DT include abnormal liver function, old age, severity of withdrawal symptoms, concurrent medical illness, heavy alcohol use, self-detox, previous history of DT, low potassium, low magnesium, and thiamine deficiency.

      Pharmacologically assisted detox is often necessary for those who regularly consume more than 15 units of alcohol per day, and inpatient detox may be needed for those who regularly consume more than 30 units per day. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess the severity of withdrawal symptoms and guide treatment decisions. Benzodiazepines are the mainstay of treatment, as chronic alcohol exposure results in decreased overall brain excitability and compensatory decrease of GABA-A neuroreceptor response to GABA. Chlordiazepoxide is a good first-line agent, while oxazepam, temazepam, and lorazepam are useful in patients with liver disease. Clomethiazole is effective but carries a high risk of respiratory depression and is not recommended. Thiamine should be offered to prevent Wernicke’s encephalopathy, and long-acting benzodiazepines can be used as prophylaxis for withdrawal seizures. Haloperidol is the treatment of choice if an antipsychotic is required.

    • What factors have been associated with the development of pathological gambling?

      Your Answer: Aripiprazole

      Explanation:

      Case reports provide evidence indicating a possible link between aripiprazole and pathological gambling, which is believed to be caused by the drug’s dopamine agonist properties. This hypothesis is supported by the observation of impulse disorders and pathological gambling in patients receiving dopamine replacement therapy for Parkinson’s disease.

      Problem Gambling: Screening and Interventions

      Problem gambling, also known as pathological gambling, refers to gambling that causes harm to personal, family, of recreational pursuits. The prevalence of problem gambling in adults ranges from 7.3% to 0.7%, while in psychiatric patients, it ranges from 6% to 12%. Problem gambling typically starts in early adolescence in males and runs a chronic, progressive course with periods of abstinence and relapses.

      Screening for problem gambling is done using various tools, including the NODS-CLiP and the South Oaks Gambling Screen (SOGS). Brief interventions have been successful in decreasing gambling, with motivational enhancement therapy (MET) being the most effective. Pharmacological interventions, such as selective serotonin reuptake inhibitors (SSRIs), naltrexone, and mood stabilizers, have also been effective, but the choice of drug depends on the presence of comorbidity. Psychological interventions, particularly cognitive-behavioral treatments, show promise, but long-term follow-up and high drop-out rates are major limitations. Studies comparing psychological and pharmacological interventions are needed.

      Which of the following statements is accurate regarding her anxiety?

      Your Answer: It indicates alcohol dependence, and after initial worsening with withdrawal usually will improve after three weeks of abstinence from alcohol

      Explanation:

      This man is experiencing anxiety in the morning due to his dependence on alcohol. Mild alcohol withdrawal commonly causes symptoms such as agitation, fever, sweats, and tremors, which can all be alleviated by consuming alcohol. However, if the patient continues to refrain from drinking, these symptoms typically reach their peak after 72 hours and can last up to a week of more, but usually subside within three weeks.

    Correct

    • What element was included in the original concept of the alcohol dependence syndrome by Edwards and Gross but is not present in the ICD-11 concept of the dependence syndrome?

      Your Answer: Rapid reinstatement of symptoms after a period of abstinence

      Explanation:

      It is important to pay close attention to the question being asked. The question inquires about an item that was present in the original classification but not included in ICD-11. While salience is present in both classifications, the Edwards and Gross feature of ‘salience of drink seeking behaviour’ is equivalent to the ICD-11 feature of ‘Increasing precedence of alcohol use over other aspects of life’. The original classification included ‘rapid reinstatement of symptoms after a period of abstinence’, which is not present in ICD-11.

      Alcohol Dependence Syndrome: ICD-11 and DSM 5 Criteria

      The criteria for diagnosing alcohol dependence syndrome in the ICD-11 and DSM 5 are quite similar, as both are based on the original concept developed by Edwards and Gross in 1976. The original concept had seven elements, including narrowing of the drinking repertoire, salience of drink seeking behavior, tolerance, withdrawal symptoms, relief of withdrawal by further drinking, compulsion to drink, and rapid reinstatement of symptoms after a period of abstinence.

      The DSM-5 Alcohol Use Disorder criteria include a problematic pattern of alcohol use leading to clinically significant impairment of distress, as manifested by at least two of the following occurring within a 12-month period. These include taking alcohol in larger amounts of over a longer period than intended, persistent desire of unsuccessful efforts to cut down of control alcohol use, spending a great deal of time in activities necessary to obtain alcohol, craving of a strong desire of urge to use alcohol, recurrent alcohol use resulting in a failure to fulfill major role obligations, continued alcohol use despite having persistent or recurrent social of interpersonal problems, giving up of reducing important social, occupational, of recreational activities due to alcohol use, recurrent alcohol use in physically hazardous situations, and continued alcohol use despite knowledge of having a persistent or recurrent physical or psychological problem caused or exacerbated by alcohol. Tolerance and withdrawal symptoms are also included in the criteria.

      The ICD-11 Alcohol Dependence criteria include a pattern of recurrent episodic of continuous use of alcohol with evidence of impaired regulation of alcohol use, manifested by impaired control over alcohol use, increasing precedence of alcohol use over other aspects of life, and physiological features indicative of neuroadaptation to the substance, including tolerance to the effects of alcohol of a need to use increasing amounts of alcohol to achieve the same effect, withdrawal symptoms following cessation of reduction in use of alcohol, of repeated use of alcohol of pharmacologically similar substances to prevent of alleviate withdrawal symptoms. The features of dependence are usually evident over a period of at least 12 months, but the diagnosis may be made if use is continuous for at least 3 months.

    • What is the most distinctive feature of pellagra?

      Your Answer: Dermatitis

      Explanation:

      Pellagra: A Vitamin B3 Deficiency Disease

      Pellagra is a disease caused by a lack of vitamin B3 (niacin) in the body. The name pellagra comes from the Italian words pelle agra, which means rough of sour skin. This disease is common in developing countries where corn is a major food source, of during prolonged disasters like famine of war. In developed countries, pellagra is rare because many foods are fortified with niacin. However, alcoholism is a common cause of pellagra in developed countries. Alcohol dependence can worsen pellagra by causing malnutrition, gastrointestinal problems, and B vitamin deficiencies. It can also inhibit the conversion of tryptophan to niacin and promote the accumulation of 5-ALA and porphyrins.

      Pellagra affects a wide range of organs and tissues in the body, so its symptoms can vary. The classic symptoms of pellagra are known as the three Ds: diarrhea, dermatitis, and dementia. Niacin deficiency can cause dementia, depression, mania, and psychosis, which is called pellagra psychosis. The most noticeable symptom of pellagra is dermatitis, which is a hyperpigmented rash that appears on sun-exposed areas of the skin. This rash is usually symmetrical and bilateral, and it is often described as Casal’s necklace when it appears on the neck.

      Your Answer: Persistent hallucinations

      Explanation:

      It is uncommon for individuals experiencing alcohol withdrawal to have transient hallucinations, as they are not a typical symptom.

      Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days.

Over the past few hours, the patient has been experiencing confusion, disorientation, and hallucinations. He also has a fever, is experiencing a rapid heartbeat, and has high blood pressure. The family member informs you that the patient recently made the decision to quit drinking.
      When was the patient's last alcoholic drink most likely consumed?

      Your Answer: 48-72 hours

      Explanation:

      The vignette depicts delirium tremens (DTs), which is characterized by confusion, hallucinations, and autonomic hyperactivity. Typically, these symptoms appear 2 to 3 days after cessation of alcohol consumption and can worsen over the next few days. Mild withdrawal symptoms such as anxiety, tremors, headache, nausea, vomiting, insomnia, and sweating may occur within 6 hours of stopping drinking. Hallucinations may occur 12-24 hours after cessation, and seizures may occur within 24 to 48 hours.

      Benzodiazepines, such as chlordiazepoxide, are commonly used to treat alcohol withdrawal, with a reducing regime. Lorazepam, due to its short half-life, is preferred as the first-line treatment for DTs. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess alcohol withdrawal.

      Explanation:

      In an inpatient of residential setting, the recommended duration for opioid detoxification is typically no more than 4 weeks, while in a community setting, it can last up to 12 weeks.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days. Buprenorphine withdrawal lasts up to 10 days and includes symptoms like myalgia, anxiety, and increased drug craving.

      Opioids affect the brain through opioid receptors, with the µ receptor being the main target for opioids.

    Correct

    • If a woman undergoing methadone detoxification informs you that she is four months pregnant, what actions should you take?

      Your Answer: Maintain the same dose of methadone

      Explanation:

      The process of detoxing from methadone can last for several months, while detoxing from buprenorphine is typically faster and can be completed in less than a week, although it usually takes a few weeks. The primary objective in this scenario is to achieve stability. According to NICE guidelines, stability is prioritized over reducing the dosage. However, if the woman insists, detoxification could be supported during her second trimester, but it would not be the preferred approach.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days.

      Explanation:

      Wernicke’s Encephalopathy: Symptoms, Causes, and Treatment

      Wernicke’s encephalopathy is a serious condition that is characterized by confusion, ophthalmoplegia, and ataxia. However, the complete triad is only present in 10% of cases, which often leads to underdiagnosis. The condition results from prolonged thiamine deficiency, which is commonly seen in people with alcohol dependency, but can also occur in other conditions such as anorexia nervosa, malignancy, and AIDS.

      The onset of Wernicke’s encephalopathy is usually abrupt, but it may develop over several days to weeks. The lesions occur in a symmetrical distribution in structures surrounding the third ventricle, aqueduct, and fourth ventricle. The mammillary bodies are involved in up to 80% of cases, and atrophy of these structures is specific for Wernicke’s encephalopathy.

      Treatment involves intravenous thiamine, as oral forms of B1 are poorly absorbed. IV glucose should be avoided when thiamine deficiency is suspected as it can precipitate of exacerbate Wernicke’s. With treatment, ophthalmoplegia and confusion usually resolve within days, but the ataxia, neuropathy, and nystagmus may be prolonged of permanent.

      Untreated cases of Wernicke’s encephalopathy can lead to Korsakoff’s syndrome, which is characterized by memory impairment associated with confabulation. The mortality rate associated with Wernicke’s encephalopathy is 10-20%, making early diagnosis and treatment crucial.

      Pellagra: A Vitamin B3 Deficiency Disease

      Pellagra is a disease caused by a lack of vitamin B3 (niacin) in the body. The name pellagra comes from the Italian words pelle agra, which means rough of sour skin. This disease is common in developing countries where corn is a major food source, of during prolonged disasters like famine of war. In developed countries, pellagra is rare because many foods are fortified with niacin. However, alcoholism is a common cause of pellagra in developed countries. Alcohol dependence can worsen pellagra by causing malnutrition, gastrointestinal problems, and B vitamin deficiencies. It can also inhibit the conversion of tryptophan to niacin and promote the accumulation of 5-ALA and porphyrins.

      Pellagra affects a wide range of organs and tissues in the body, so its symptoms can vary. The classic symptoms of pellagra are known as the three Ds: diarrhea, dermatitis, and dementia. Niacin deficiency can cause dementia, depression, mania, and psychosis, which is called pellagra psychosis. The most noticeable symptom of pellagra is dermatitis, which is a hyperpigmented rash that appears on sun-exposed areas of the skin. This rash is usually symmetrical and bilateral, and it is often described as Casal’s necklace when it appears on the neck.

    Incorrect

    • What is the maintenance treatment used for individuals with opioid dependence syndrome?

      Your Answer: Naltrexone

      Correct Answer: Methadone

      Explanation:

      Synthetic opioids like methadone and buprenorphine are utilized as a replacement for heroin. Alpha2 adrenergic agonists such as clonidine and lofexidine are employed in detox settings to alleviate a range of opioid withdrawal symptoms.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days. Buprenorphine withdrawal lasts up to 10 days and includes symptoms like myalgia, anxiety, and increased drug craving.

      Opioids affect the brain through opioid receptors, with the µ receptor being the main target for opioids. Dopaminergic cells in the ventral tegmental area produce dopamine, which is released into the nucleus accumbens upon stimulation of µ receptors, producing euphoria and reward. With repeat opioid exposure, µ receptors become less responsive, causing dysphoria and drug craving.

      Methadone and buprenorphine are maintenance-oriented treatments for opioid dependence. Methadone is a full agonist targeting µ receptors, while buprenorphine is a partial agonist targeting µ receptors and a partial k agonist of functional antagonist. Naloxone and naltrexone are antagonists targeting all opioid receptors.

      Methadone is preferred over buprenorphine for detoxification, and ultra-rapid detoxification should not be offered. Lofexidine may be considered for mild of uncertain dependence. Clonidine and dihydrocodeine should not be used routinely in opioid detoxification. The duration of detoxification should be up to 4 weeks in an inpatient setting and up to 12 weeks in a community setting.

      Pregnant women dependent on opioids should use opioid maintenance treatment rather than attempt detoxification. Methadone is preferred over buprenorphine, and transfer to buprenorphine during pregnancy is not advised. Detoxification should only be considered if appropriate for the women’s wishes, circumstances, and ability to cope. Methadone or buprenorphine treatment is not a contraindication to breastfeeding.

    Correct

    • In the UK, Methadone is categorized under which controlled drug schedule?

      Your Answer: 2

      Explanation:

      Drug Misuse (Law and Scheduling)

      The Misuse of Drugs Act (1971) regulates the possession and supply of drugs, classifying them into three categories: A, B, and C. The maximum penalty for possession varies depending on the class of drug, with Class A drugs carrying a maximum sentence of 7 years.

      The Misuse of Drugs Regulations 2001 further categorizes controlled drugs into five schedules. Schedule 1 drugs are considered to have no therapeutic value and cannot be lawfully possessed of prescribed, while Schedule 2 drugs are available for medical use but require a controlled drug prescription. Schedule 3, 4, and 5 drugs have varying levels of restrictions and requirements.

      It is important to note that a single drug can have multiple scheduling statuses, depending on factors such as strength and route of administration. For example, morphine and codeine can be either Schedule 2 of Schedule 5.

      Overall, the Misuse of Drugs Act and Regulations aim to regulate and control the use of drugs in the UK, with the goal of reducing drug misuse and related harm.

    Correct

    • In drug testing, which substance commonly used for weight loss and bodybuilding, is known to cause inaccurate results?

      Your Answer: Amphetamines

      Explanation:

      Originally developed as a nasal decongestant, dimethylamylamine is now available as a dietary supplement for purposes such as weight loss, enhancing athletic abilities, and building muscle mass. However, it is important to note that this substance is artificially produced in a laboratory.

      Drug Testing

      There are two main approaches to testing for illicit substances: immunoassays and lab testing. Immunoassays are a cheap and quick screening method, but not very specific. Lab testing is more accurate but time-consuming and expensive. Drug testing can be done through urine, saliva, blood, hair, and sweat, although hair and sweat are rarely used in mental health settings.

      False positives can occur when testing for illicit substances, so it’s important to check that patients are not taking other medications that could produce a false positive result. For example, common medications that can lead to false positive results include dimethylamylamine, ofloxacin, bupropion, phenothiazines, trazodone, and methylphenidate for amphetamines/methamphetamines; sertraline and efavirenz for benzodiazepines and cannabis; topical anesthetics for cocaine; codeine, dihydrocodeine, and methadone for opioids; lamotrigine, tramadol, and venlafaxine for PCP; and amitriptyline, bupropion, buspirone, chlorpromazine, fluoxetine, sertraline, and verapamil for LSD.

      In summary, drug testing is an important tool in mental health settings, but it’s crucial to consider potential false positives and medication interactions when interpreting results.

      Your Answer: Standard urine drug tests for amphetamine may detect MDMA

      Explanation:

      It is unlikely for passive inhalation of cannabis and crack to result in a positive drug test, unless the individual has been exposed to heavy and prolonged smoke in a highly contaminated environment.

      Drug Screening

      Drug testing can be conducted through various methods, but urinalysis is the most common. Urine drug tests can be either screening of confirmatory. Screening tests use enzymatic immunoassays to detect drug metabolites of classes of drug metabolites in the urine. However, these tests have limitations, such as false positives due to cross-reactivity. Therefore, any positive test should be confirmed through gas chromatography of mass spectrometry.

      People may try to manipulate drug testing procedures by adulterating the sample. Normal urine parameters, such as temperature, specific gravity, and pH, can assist in detecting adulterated samples. Adulterants include household items like vinegar, detergent, and ammonia, as well as commercially available products. Diluted urine may also yield false negatives.

      Detection times vary from person to person, and the approximate drug detection time in urine can be found in a table provided by Nelson (2016). False positives can occur due to cross-reactivity, as illustrated by Moeller (2017). Clinicians should be aware of the limitations of urine drug tests and the potential for manipulation.

      Your Answer: The recommended course of treatment with varenicline is 12 weeks

      Explanation:

      Smoking cessation can be achieved through various methods, including nicotine replacement therapy (NRT), bupropion, and varenicline. NRT is available in different forms, including patches, gum, lozenges, inhalators, and nasal spray. Combination treatment with NRT has been found to be more effective than a single product of placebo. Bupropion is a selective inhibitor of dopamine and noradrenaline reuptake and is presumed to work directly on the brain pathways involved in addiction and withdrawal. It is recommended to start bupropion while still smoking and to discontinue after 7-9 weeks. Varenicline is a partial nicotinic receptor agonist that reduces the rewarding and reinforcing effects of smoking. It is recommended to start varenicline while still smoking and to continue for 12 weeks. Nausea is the most common adverse effect of varenicline, and depression has been reported in some users. Bupropion and varenicline should be avoided in certain populations, including those with a history of bipolar disorder, epilepsy, and pregnancy of breastfeeding.

    • A 35-year old woman reported hearing voices instructing her to harm herself. She is currently not employed, having left her job two years ago. What substance is most likely responsible for her dependence?

      Your Answer: Alcohol

      Correct Answer: Amphetamines

      Explanation:

      The patient’s symptoms suggest the presence of Schneider’s first rank symptom, which is characterized by actions perceived as influenced of made by external agents. It is important to note that amphetamines can cause drug-induced psychosis, which can mimic schizophrenia. While benzodiazepines are not known to induce schizophrenia, there have been reports of auditory hallucinations during benzodiazepine withdrawal. On the other hand, GHB is not associated with drug-induced schizophrenia, and while opiates may cause hallucinations, they do not typically result in Schneider’s first rank symptoms. It is important to consider the possibility of a dual-diagnosis scenario, where the patient may have both a drug dependency and schizophrenia, which may have been triggered by drug use of stress, but is not solely drug-induced.

    Incorrect

    • After how much time since the last drink do the symptoms of alcohol withdrawal typically start?

      Your Answer: 12-24 hours

      Correct Answer: 3-12 hrs

      Explanation:

      Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days. Withdrawal seizures may occur before blood alcohol levels reach zero, and a small percentage of people may experience delirium tremens (DT), which can be fatal if left untreated. Risk factors for DT include abnormal liver function, old age, severity of withdrawal symptoms, concurrent medical illness, heavy alcohol use, self-detox, previous history of DT, low potassium, low magnesium, and thiamine deficiency.

      Pharmacologically assisted detox is often necessary for those who regularly consume more than 15 units of alcohol per day, and inpatient detox may be needed for those who regularly consume more than 30 units per day. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess the severity of withdrawal symptoms and guide treatment decisions. Benzodiazepines are the mainstay of treatment, as chronic alcohol exposure results in decreased overall brain excitability and compensatory decrease of GABA-A neuroreceptor response to GABA. Chlordiazepoxide is a good first-line agent, while oxazepam, temazepam, and lorazepam are useful in patients with liver disease. Clomethiazole is effective but carries a high risk of respiratory depression and is not recommended. Thiamine should be offered to prevent Wernicke’s encephalopathy, and long-acting benzodiazepines can be used as prophylaxis for withdrawal seizures. Haloperidol is the treatment of choice if an antipsychotic is required.

    • A young woman attends clinic. She is addicted to heroin and is keen to enter a detoxification program. Which of the following is the best time for her to do this?

      Your Answer: Second trimester

      Explanation:

      While opioid detoxification is possible during pregnancy, it is important to note that the first and third trimesters are considered the riskiest times to attempt it. During the first trimester, it is recommended to stabilize the woman due to the increased risk of spontaneous abortion. In the second trimester, detoxification can be done in small, frequent reductions, as long as illicit opiate use does not continue. However, it is generally not recommended to attempt detoxification in the third trimester as even mild maternal withdrawal can cause foetal stress, distress, and potentially stillbirth.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days.

      Explanation:

      Withdrawal from amphetamine, commonly referred to as speed, usually leads to an increase in appetite rather than a decrease.

      Illicit drugs, also known as illegal drugs, are substances that are prohibited by law and can have harmful effects on the body and mind. Some of the most commonly used illicit drugs in the UK include opioids, amphetamines, cocaine, MDMA (ecstasy), cannabis, and hallucinogens.

      Opioids, such as heroin, are highly addictive and can cause euphoria, drowsiness, constipation, and respiratory depression. Withdrawal symptoms may include piloerection, insomnia, restlessness, dilated pupils, yawning, sweating, and abdominal cramps.

      Amphetamines and cocaine are stimulants that can increase energy, cause insomnia, hyperactivity, euphoria, and paranoia. Withdrawal symptoms may include hypersomnia, hyperphagia, depression, irritability, agitation, vivid dreams, and increased appetite.

      MDMA, also known as ecstasy, can cause increased energy, sweating, jaw clenching, euphoria, enhanced sociability, and increased response to touch. Withdrawal symptoms may include depression, insomnia, depersonalisation, and derealisation.

      Cannabis, also known as marijuana of weed, can cause relaxation, intensified sensory experience, paranoia, anxiety, and injected conjunctiva. Withdrawal symptoms may include insomnia, reduced appetite, and irritability.

      Hallucinogens, such as LSD, can cause perceptual changes, pupillary dilation, tachycardia, sweating, palpitations, tremors, and incoordination. There is no recognised withdrawal syndrome for hallucinogens.

      Ketamine, also known as Vitamin K, Super K, Special K, of donkey dust, can cause euphoria, dissociation, ataxia, and hallucinations. There is no recognised withdrawal syndrome for ketamine.

      Opioids, such as heroin, are highly addictive and can cause euphoria, drowsiness, constipation, and respiratory depression. Withdrawal symptoms may include piloerection, insomnia, restlessness, dilated pupils, yawning, sweating, and abdominal cramps.

      Amphetamines and cocaine are stimulants that can increase energy, cause insomnia, hyperactivity, euphoria, and paranoia. Withdrawal symptoms may include hypersomnia, hyperphagia, depression, irritability, agitation, vivid dreams, and increased appetite.

      MDMA, also known as ecstasy, can cause increased energy, sweating, jaw clenching, euphoria, enhanced sociability, and increased response to touch. Withdrawal symptoms may include depression, insomnia, depersonalisation, and derealisation.

      Cannabis, also known as marijuana of weed, can cause relaxation, intensified sensory experience, paranoia, anxiety, and injected conjunctiva. Withdrawal symptoms may include insomnia, reduced appetite, and irritability.

      Hallucinogens, such as LSD, can cause perceptual changes, pupillary dilation, tachycardia, sweating, palpitations, tremors, and incoordination. There is no recognised withdrawal syndrome for hallucinogens.

      Ketamine, also known as Vitamin K, Super K, Special K, of donkey dust, can cause euphoria, dissociation, ataxia, and hallucinations. There is no recognised withdrawal syndrome for ketamine.

  • Question 55 - A 54 year old man is admitted to hospital following a hip fracture....

    Correct

    • A 54 year old man is admitted to hospital following a hip fracture. In view of a shortage of theatre space his operation is delayed. Three days following admission the nurse becomes concerned by his change in presentation. She has noticed that the man has become increasingly agitated, and has a sustained tachycardia. He has also started complaining that he is hearing people talking about him despite him being in a side room. Which of the following do you most suspect?

      Your Answer: Delirium tremens

      Explanation:

      The man’s symptoms of agitation and hallucinations could be attributed to a psychotic illness, but the presence of a sustained tachycardia suggests another underlying condition. Based on the delayed presentation and the complete set of symptoms, delirium tremens is the most probable explanation. While meningitis is a possibility, it is less likely than delirium tremens, which is a common condition.

      Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days. Withdrawal seizures may occur before blood alcohol levels reach zero, and a small percentage of people may experience delirium tremens (DT), which can be fatal if left untreated. Risk factors for DT include abnormal liver function, old age, severity of withdrawal symptoms, concurrent medical illness, heavy alcohol use, self-detox, previous history of DT, low potassium, low magnesium, and thiamine deficiency.

      Pharmacologically assisted detox is often necessary for those who regularly consume more than 15 units of alcohol per day, and inpatient detox may be needed for those who regularly consume more than 30 units per day. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess the severity of withdrawal symptoms and guide treatment decisions. Benzodiazepines are the mainstay of treatment, as chronic alcohol exposure results in decreased overall brain excitability and compensatory decrease of GABA-A neuroreceptor response to GABA. Chlordiazepoxide is a good first-line agent, while oxazepam, temazepam, and lorazepam are useful in patients with liver disease. Clomethiazole is effective but carries a high risk of respiratory depression and is not recommended. Thiamine should be offered to prevent Wernicke’s encephalopathy, and long-acting benzodiazepines can be used as prophylaxis for withdrawal seizures. Haloperidol is the treatment of choice if an antipsychotic is required.

    Correct

    • A patient in his late 60s with a long standing dependence on alcohol attends his GP complaining of dizziness and abdominal pain. He explains that he has had a cold for a few days and thinks it may be connected. He attended the substance misuse clinic two weeks ago and was prescribed a medication to help him remain abstinent from alcohol. He assures you that he has been abstinent from alcohol for the past two weeks. Based on his presentation, which of the following would you suspect he has been prescribed by the clinic?:

      Your Answer: Disulfiram

      Explanation:

      Chlordiazepoxide and clomethiazole are medications prescribed for managing symptoms of alcohol withdrawal.

      Anticonvulsants are not recommended for relapse prevention in alcohol dependence. While some studies have shown potential benefits for certain anticonvulsants, such as carbamazepine and valproate, the evidence is not strong enough to support their routine use. Additionally, these drugs can have significant side effects, including liver toxicity and blood disorders, and require careful monitoring. Therefore, they are not recommended by NICE for this indication.

    Correct

    • Which vitamin is referred to as thiamine?

      Your Answer: Vitamin B1

      Explanation:

      Korsakoff’s Syndrome

      Korsakoff’s Syndrome, also known as amnesic syndrome, is a chronic condition that affects recent and anterograde memory in an alert and responsive patient. It is caused by prolonged thiamine (vitamin B1) deficiency and often follows Wernicke’s encephalopathy. The syndrome is characterized by a lack of insight, apathy, and confabulation. Thiamine is essential for glucose metabolism in the brain, and its deficiency leads to a toxic buildup of glucose, causing neuronal loss. The Mammillary bodies are the main areas affected in Korsakoff’s syndrome.

      While intelligence on the WAIS is preserved, episodic memory is severely affected in Korsakoff’s syndrome. Semantic memory is variably affected, but implicit aspects of memory, such as response to priming and procedural memory, are preserved. Immediate memory tested with the digit span is normal, but information can only be retained for a few minutes at most. Patients with Korsakoff’s syndrome often display apathy, lack of initiative, and profound lack of insight.

    • Which of the following is not a recognised method for testing illicit substances?

      Your Answer: Urine

      Correct Answer: Nasal mucus

      Explanation:

      Testing for drugs cannot be done through nasal mucus.

      Drug Testing

      There are two main approaches to testing for illicit substances: immunoassays and lab testing. Immunoassays are a cheap and quick screening method, but not very specific. Lab testing is more accurate but time-consuming and expensive. Drug testing can be done through urine, saliva, blood, hair, and sweat, although hair and sweat are rarely used in mental health settings.

      False positives can occur when testing for illicit substances, so it’s important to check that patients are not taking other medications that could produce a false positive result. For example, common medications that can lead to false positive results include dimethylamylamine, ofloxacin, bupropion, phenothiazines, trazodone, and methylphenidate for amphetamines/methamphetamines; sertraline and efavirenz for benzodiazepines and cannabis; topical anesthetics for cocaine; codeine, dihydrocodeine, and methadone for opioids; lamotrigine, tramadol, and venlafaxine for PCP; and amitriptyline, bupropion, buspirone, chlorpromazine, fluoxetine, sertraline, and verapamil for LSD.

      In summary, drug testing is an important tool in mental health settings, but it’s crucial to consider potential false positives and medication interactions when interpreting results.

      Correct Answer: 7%

      Explanation:

      Alcohol Dependence and Suicide Risk

      Alcohol dependence is a significant factor that increases the likelihood of suicidal behavior. According to Inskip’s (1998) research, individuals with alcohol dependence have a lifetime risk of suicide estimated at 7%, which is significantly higher than the general population’s risk of approximately 1%. This finding highlights the importance of addressing alcohol dependence as a risk factor for suicide and providing appropriate interventions and support to individuals struggling with alcohol addiction.

    Correct

    • NICE recommends which treatment as the initial approach for opioid detoxification?

      Your Answer: Methadone

      Explanation:

      The recommended initial treatment for opioid detoxification is methadone of buprenorphine.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days. Buprenorphine withdrawal lasts up to 10 days and includes symptoms like myalgia, anxiety, and increased drug craving.

      Opioids affect the brain through opioid receptors, with the µ receptor being the main target for opioids. Dopaminergic cells in the ventral tegmental area produce dopamine, which is released into the nucleus accumbens upon stimulation of µ receptors, producing euphoria and reward. With repeat opioid exposure, µ receptors become less responsive, causing dysphoria and drug craving.

      Methadone and buprenorphine are maintenance-oriented treatments for opioid dependence. Methadone is a full agonist targeting µ receptors, while buprenorphine is a partial agonist targeting µ receptors and a partial k agonist of functional antagonist. Naloxone and naltrexone are antagonists targeting all opioid receptors.

      Methadone is preferred over buprenorphine for detoxification, and ultra-rapid detoxification should not be offered. Lofexidine may be considered for mild of uncertain dependence. Clonidine and dihydrocodeine should not be used routinely in opioid detoxification. The duration of detoxification should be up to 4 weeks in an inpatient setting and up to 12 weeks in a community setting.

      Pregnant women dependent on opioids should use opioid maintenance treatment rather than attempt detoxification. Methadone is preferred over buprenorphine, and transfer to buprenorphine during pregnancy is not advised. Detoxification should only be considered if appropriate for the women’s wishes, circumstances, and ability to cope. Methadone or buprenorphine treatment is not a contraindication to breastfeeding.

      Marchiafava-Bignami disease is a rare condition that is commonly observed in individuals with alcoholism and malnutrition. The disease is characterized by the progressive demyelination and subsequent necrosis of the corpus callosum, which can lead to a range of nonspecific clinical symptoms such as motor of cognitive disturbances. The course of the disease can be either acute of chronic, and patients may experience dementia, spasticity, dysarthria, and an inability to walk. The outcome of the disease is unpredictable, with some patients lapsing into a coma and dying, while others may survive for many years in a demented state, of even recover.

      Explanation:

      The use of high doses of opioid antagonists (naloxone and naltrexone) in ultra-rapid detox (over 24 hours) and rapid detox (over 1-5 days) is common. However, ultra-rapid detox is typically performed under general anesthesia, while rapid detox is usually done with some sedation. Despite this, NICE does not support the use of ultra-rapid detox. NICE recommends that rapid detox be offered only to individuals who specifically request it, provided that the service can safely provide it.

      Tolerance in Opiate Abuse

      Tolerance is a common phenomenon that occurs in opiate abuse. It develops regarding the analgesic, euphoric, sedative, respiratory depressant, and nauseating effects of opioids. However, it does not develop to their effects on miosis and bowel motility, which can cause constipation. This means that individuals who abuse opioids may require higher doses to achieve the desired effects, leading to an increased risk of overdose and other adverse effects. Understanding the mechanisms involved in tolerance can help in developing effective interventions to prevent and treat opiate abuse.

      Explanation:

      Suboxone vs. Subutex: What’s the Difference?

      Suboxone and Subutex are both medications used to treat opioid addiction. However, there are some key differences between the two.

      Suboxone is a combination of buprenorphine and naloxone. The naloxone is added to prevent people from injecting the medication, as this was a common problem with pure buprenorphine tablets. If someone tries to inject Suboxone, the naloxone will cause intense withdrawal symptoms. However, if the tablet is swallowed as directed, the naloxone is not absorbed by the gut and does not cause any problems.

      Subutex, on the other hand, contains only buprenorphine and does not include naloxone. This means that it may be more likely to be abused by injection, as there is no deterrent to prevent people from doing so.

      Overall, both Suboxone and Subutex can be effective treatments for opioid addiction, but Suboxone may be a safer choice due to the addition of naloxone.

      Drug Misuse (Law and Scheduling)

      The Misuse of Drugs Act (1971) regulates the possession and supply of drugs, classifying them into three categories: A, B, and C. The maximum penalty for possession varies depending on the class of drug, with Class A drugs carrying a maximum sentence of 7 years.

      The Misuse of Drugs Regulations 2001 further categorizes controlled drugs into five schedules. Schedule 1 drugs are considered to have no therapeutic value and cannot be lawfully possessed of prescribed, while Schedule 2 drugs are available for medical use but require a controlled drug prescription. Schedule 3, 4, and 5 drugs have varying levels of restrictions and requirements.

      It is important to note that a single drug can have multiple scheduling statuses, depending on factors such as strength and route of administration. For example, morphine and codeine can be either Schedule 2 of Schedule 5.

      Overall, the Misuse of Drugs Act and Regulations aim to regulate and control the use of drugs in the UK, with the goal of reducing drug misuse and related harm.

      Your Answer: IV glucose

      Explanation:

      It is possible that the man is experiencing alcohol withdrawal, which often causes fluid imbalances that need to be addressed. However, administering intravenous glucose is not recommended as it could lead to Wernicke’s encephalopathy. While beta blockers have been found to be helpful in treating alcohol withdrawal, this is not a widely used method. A resource for further information on this topic is the article Alcohol Withdrawal Syndrome by Bayard M. in the March 15, 2004 issue of American Family Physician.

      Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days. Withdrawal seizures may occur before blood alcohol levels reach zero, and a small percentage of people may experience delirium tremens (DT), which can be fatal if left untreated. Risk factors for DT include abnormal liver function, old age, severity of withdrawal symptoms, concurrent medical illness, heavy alcohol use, self-detox, previous history of DT, low potassium, low magnesium, and thiamine deficiency.

      Pharmacologically assisted detox is often necessary for those who regularly consume more than 15 units of alcohol per day, and inpatient detox may be needed for those who regularly consume more than 30 units per day. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess the severity of withdrawal symptoms and guide treatment decisions. Benzodiazepines are the mainstay of treatment, as chronic alcohol exposure results in decreased overall brain excitability and compensatory decrease of GABA-A neuroreceptor response to GABA. Chlordiazepoxide is a good first-line agent, while oxazepam, temazepam, and lorazepam are useful in patients with liver disease. Clomethiazole is effective but carries a high risk of respiratory depression and is not recommended. Thiamine should be offered to prevent Wernicke’s encephalopathy, and long-acting benzodiazepines can be used as prophylaxis for withdrawal seizures. Haloperidol is the treatment of choice if an antipsychotic is required.

      Explanation:

      Reducing Alcohol-Related Harm

      According to NICE (2010), the most effective and targeted approach to reducing heavy drinking and alcohol-related harm is through implementing a minimum alcohol price. Additionally, limiting the availability of alcohol by reducing the number of outlets selling it in a specific area and restricting the days and hours when it can be sold is another effective strategy.

      Your Answer: Nystagmus is a common feature

      Explanation:

      PCP Intoxication: A Dangerous Hallucinogenic

      Phencyclidine (PCP), also known as angel dust, is a hallucinogenic drug that is popular for inducing feelings of euphoria, superhuman strength, and social and sexual prowess. It is a NMDA receptor antagonist that has dissociative properties, similar to ketamine. PCP was previously used as an anesthetic and animal tranquilizer, but was soon recalled due to its adverse effects, including psychosis, agitation, and dysphoria post-operatively.

      PCP is available in various forms, including white crystalline powder, tablets, crystals, and liquid. It can be snorted, smoked, ingested, of injected intravenously or subcutaneously. People who have taken PCP often present with violent behavior, nystagmus, tachycardia, hypertension, anesthesia, and analgesia. Other symptoms include impaired motor function, hallucinations, delusions, and paranoia.

      PCP intoxication is best managed with benzodiazepines along with supportive measures for breathing and circulation. Antipsychotics are not recommended as they can amplify PCP-induced hyperthermia, dystonic reactions, and lower the seizure threshold. However, haloperidol may be useful for treating PCP-induced psychosis in patients who are not hyperthermic. Most deaths in PCP-intoxicated patients result from violent behavior rather than direct effects of the drug.

      Your Answer: Mental status changes

      Explanation:

      Wernicke’s Encephalopathy: Symptoms, Causes, and Treatment

      Wernicke’s encephalopathy is a serious condition that is characterized by confusion, ophthalmoplegia, and ataxia. However, the complete triad is only present in 10% of cases, which often leads to underdiagnosis. The condition results from prolonged thiamine deficiency, which is commonly seen in people with alcohol dependency, but can also occur in other conditions such as anorexia nervosa, malignancy, and AIDS.

      The onset of Wernicke’s encephalopathy is usually abrupt, but it may develop over several days to weeks. The lesions occur in a symmetrical distribution in structures surrounding the third ventricle, aqueduct, and fourth ventricle. The mammillary bodies are involved in up to 80% of cases, and atrophy of these structures is specific for Wernicke’s encephalopathy.

      Treatment involves intravenous thiamine, as oral forms of B1 are poorly absorbed. IV glucose should be avoided when thiamine deficiency is suspected as it can precipitate of exacerbate Wernicke’s. With treatment, ophthalmoplegia and confusion usually resolve within days, but the ataxia, neuropathy, and nystagmus may be prolonged of permanent.

      Untreated cases of Wernicke’s encephalopathy can lead to Korsakoff’s syndrome, which is characterized by memory impairment associated with confabulation. The mortality rate associated with Wernicke’s encephalopathy is 10-20%, making early diagnosis and treatment crucial.

    Correct

    • What are some indications on a urinalysis that suggest the sample may have been tampered with and is therefore unreliable for drug testing?

      Your Answer: Temperature of 18 C

      Explanation:

      An 18 C temperature reading is below the typical range for urine, indicating that the sample may not be fresh and could potentially be a replacement sample.

      Drug Screening

      Drug testing can be conducted through various methods, but urinalysis is the most common. Urine drug tests can be either screening of confirmatory. Screening tests use enzymatic immunoassays to detect drug metabolites of classes of drug metabolites in the urine. However, these tests have limitations, such as false positives due to cross-reactivity. Therefore, any positive test should be confirmed through gas chromatography of mass spectrometry.

      People may try to manipulate drug testing procedures by adulterating the sample. Normal urine parameters, such as temperature, specific gravity, and pH, can assist in detecting adulterated samples. Adulterants include household items like vinegar, detergent, and ammonia, as well as commercially available products. Diluted urine may also yield false negatives.

      Detection times vary from person to person, and the approximate drug detection time in urine can be found in a table provided by Nelson (2016). False positives can occur due to cross-reactivity, as illustrated by Moeller (2017). Clinicians should be aware of the limitations of urine drug tests and the potential for manipulation.

    Correct

    • What is the highest possible punishment for possessing synthetic cannabinoids in the United Kingdom?

      Your Answer: 5 years

      Explanation:

      At first, the Psychoactive Substances Act only criminalized the production and supply of certain substances, while possession was still legal. However, in January 2017, synthetic cannabinoids such as Spice were reclassified as Class B drugs under the Misuse of Drugs Act, making possession of these substances illegal.

      Drug Misuse (Law and Scheduling)

      The Misuse of Drugs Act (1971) regulates the possession and supply of drugs, classifying them into three categories: A, B, and C. The maximum penalty for possession varies depending on the class of drug, with Class A drugs carrying a maximum sentence of 7 years.

      The Misuse of Drugs Regulations 2001 further categorizes controlled drugs into five schedules. Schedule 1 drugs are considered to have no therapeutic value and cannot be lawfully possessed of prescribed, while Schedule 2 drugs are available for medical use but require a controlled drug prescription. Schedule 3, 4, and 5 drugs have varying levels of restrictions and requirements.

      It is important to note that a single drug can have multiple scheduling statuses, depending on factors such as strength and route of administration. For example, morphine and codeine can be either Schedule 2 of Schedule 5.

      Overall, the Misuse of Drugs Act and Regulations aim to regulate and control the use of drugs in the UK, with the goal of reducing drug misuse and related harm.

      Your Answer: Vehicle related theft

      Correct Answer: Shoplifting

      Explanation:

      The majority of individuals in a sample undergoing drug misuse treatment disclosed engaging in criminal activities other than drug possession within the 3 months prior to initiating treatment. Shoplifting was the most frequently reported offense.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days. Buprenorphine withdrawal lasts up to 10 days and includes symptoms like myalgia, anxiety, and increased drug craving.

      Opioids affect the brain through opioid receptors, with the µ receptor being the main target for opioids. Dopaminergic cells in the ventral tegmental area produce dopamine, which is released into the nucleus accumbens upon stimulation of µ receptors, producing euphoria and reward. With repeat opioid exposure, µ receptors become less responsive, causing dysphoria and drug craving.

      Methadone and buprenorphine are maintenance-oriented treatments for opioid dependence. Methadone is a full agonist targeting µ receptors, while buprenorphine is a partial agonist targeting µ receptors and a partial k agonist of functional antagonist. Naloxone and naltrexone are antagonists targeting all opioid receptors.

      Methadone is preferred over buprenorphine for detoxification, and ultra-rapid detoxification should not be offered. Lofexidine may be considered for mild of uncertain dependence. Clonidine and dihydrocodeine should not be used routinely in opioid detoxification. The duration of detoxification should be up to 4 weeks in an inpatient setting and up to 12 weeks in a community setting.

      Pregnant women dependent on opioids should use opioid maintenance treatment rather than attempt detoxification. Methadone is preferred over buprenorphine, and transfer to buprenorphine during pregnancy is not advised. Detoxification should only be considered if appropriate for the women’s wishes, circumstances, and ability to cope. Methadone or buprenorphine treatment is not a contraindication to breastfeeding.

      Your Answer: Parenteral thiamine is suggested rather than an oral route

      Explanation:

      To ensure prompt treatment, thiamine 200 mg should be administered three times daily before any carbohydrate intake, preferably through intravenous administration. It is recommended to avoid delaying treatment by relying solely on imaging for diagnosis. Intravenous administration is preferred over oral administration, as there is a risk of anaphylaxis with intranasal administration. Therefore, intranasal administration should only be considered if facilities are available to manage potential anaphylactic reactions.

    • A teenager who is severely addicted to video games does not acknowledge the need to alter their gaming behavior and does not believe that it is negatively impacting their life. In which stage of change is the teenager?

      Your Answer: Pre-contemplation

      Explanation:

      Stages of Change Model

      Prochaska and DiClemente’s Stages of Change Model identifies five stages that individuals go through when making a change. The first stage is pre-contemplation, where the individual is not considering change. There are different types of precontemplators, including those who lack knowledge about the problem, those who are afraid of losing control, those who feel hopeless, and those who rationalize their behavior.

      The second stage is contemplation, where the individual is ambivalent about change and is sitting on the fence. The third stage is preparation, where the individual has some experience with change and is trying to change, testing the waters. The fourth stage is action, where the individual has started to introduce change, and the behavior is defined as action during the first six months of change.

      The final stage is maintenance, where the individual is involved in ongoing efforts to maintain change. Action becomes maintenance once six months have elapsed. Understanding these stages can help individuals and professionals in supporting behavior change.

    Correct

    • What is the recommended treatment for alcohol withdrawal in a patient with liver impairment?

      Your Answer: Lorazepam

      Explanation:

      Patients with impaired liver function, such as those with liver failure of elderly individuals, may be prescribed oxazepam, temazepam, of lorazepam.

      Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days. Withdrawal seizures may occur before blood alcohol levels reach zero, and a small percentage of people may experience delirium tremens (DT), which can be fatal if left untreated. Risk factors for DT include abnormal liver function, old age, severity of withdrawal symptoms, concurrent medical illness, heavy alcohol use, self-detox, previous history of DT, low potassium, low magnesium, and thiamine deficiency.

      Pharmacologically assisted detox is often necessary for those who regularly consume more than 15 units of alcohol per day, and inpatient detox may be needed for those who regularly consume more than 30 units per day. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess the severity of withdrawal symptoms and guide treatment decisions. Benzodiazepines are the mainstay of treatment, as chronic alcohol exposure results in decreased overall brain excitability and compensatory decrease of GABA-A neuroreceptor response to GABA. Chlordiazepoxide is a good first-line agent, while oxazepam, temazepam, and lorazepam are useful in patients with liver disease. Clomethiazole is effective but carries a high risk of respiratory depression and is not recommended. Thiamine should be offered to prevent Wernicke’s encephalopathy, and long-acting benzodiazepines can be used as prophylaxis for withdrawal seizures. Haloperidol is the treatment of choice if an antipsychotic is required.

    • What is the most frequently reported side effect of varenicline?

      Your Answer: Dry mouth

      Correct Answer: Nausea

      Explanation:

      Smoking cessation can be achieved through various methods, including nicotine replacement therapy (NRT), bupropion, and varenicline. NRT is available in different forms, including patches, gum, lozenges, inhalators, and nasal spray. Combination treatment with NRT has been found to be more effective than a single product of placebo. Bupropion is a selective inhibitor of dopamine and noradrenaline reuptake and is presumed to work directly on the brain pathways involved in addiction and withdrawal. It is recommended to start bupropion while still smoking and to discontinue after 7-9 weeks. Varenicline is a partial nicotinic receptor agonist that reduces the rewarding and reinforcing effects of smoking. It is recommended to start varenicline while still smoking and to continue for 12 weeks. Nausea is the most common adverse effect of varenicline, and depression has been reported in some users. Bupropion and varenicline should be avoided in certain populations, including those with a history of bipolar disorder, epilepsy, and pregnancy of breastfeeding.

      Motivational Interviewing: A Model for Resolving Ambivalence and Facilitating Change

      Motivational interviewing (MI) is an evidence-based method used for people with substance misuse problems. It was introduced by William Miller in 1983, based on his experience with alcoholics. MI focuses on exploring and resolving ambivalence and centres on the motivational process that facilitates change. It is based on three key elements: collaboration, evocation, and autonomy.

      There are four principles of MI: expressing empathy, supporting self-efficacy, rolling with resistance, and developing discrepancy. MI involves the use of micro-counseling skills called OARS, which stands for open-ended questions, affirmations, reflections, and summaries.

      Change talk is defined as statements by the client that reveal consideration of, motivation for, of commitment to change. In MI, the therapist aims to guide the client to expression of change talk. Types of change talk can be remembered by the mnemonic DARN-CAT, which stands for desire, ability, reason, need, commitment, activation, and taking steps.

      Overall, MI is a model for resolving ambivalence and facilitating change that emphasizes collaboration, evocation, and autonomy. It is a useful tool for therapists working with clients with substance misuse problems.

      Explanation:

      Schizophrenia and Cannabis Use

      The relationship between cannabis use and the risk of developing schizophrenia is a topic of ongoing debate. However, research suggests that cannabis use may increase the risk of later schizophrenia of schizophreniform disorder by two-fold (Arseneault, 2004). The risk of developing schizophrenia appears to be higher in individuals who start using cannabis at a younger age. For instance, regular cannabis smokers at the age of 15 are 4.5 times more likely to develop schizophrenia at the age of 26, compared to those who did not report regular use until age 18 (Murray, 2004).

      A systematic review published in the Lancet in 2007 found that the lifetime risk of developing psychosis increased by 40% in individuals who had ever used cannabis (Moore, 2007). Another meta-analysis reported that the age at onset of psychosis was 2.70 years younger in cannabis users than in non-users (Large, 2011). These findings suggest that cannabis use may have a significant impact on the development of schizophrenia and related disorders.

      Illicit drugs, also known as illegal drugs, are substances that are prohibited by law and can have harmful effects on the body and mind. Some of the most commonly used illicit drugs in the UK include opioids, amphetamines, cocaine, MDMA (ecstasy), cannabis, and hallucinogens.

      Opioids, such as heroin, are highly addictive and can cause euphoria, drowsiness, constipation, and respiratory depression. Withdrawal symptoms may include piloerection, insomnia, restlessness, dilated pupils, yawning, sweating, and abdominal cramps.

      Amphetamines and cocaine are stimulants that can increase energy, cause insomnia, hyperactivity, euphoria, and paranoia. Withdrawal symptoms may include hypersomnia, hyperphagia, depression, irritability, agitation, vivid dreams, and increased appetite.

      MDMA, also known as ecstasy, can cause increased energy, sweating, jaw clenching, euphoria, enhanced sociability, and increased response to touch. Withdrawal symptoms may include depression, insomnia, depersonalisation, and derealisation.

      Cannabis, also known as marijuana of weed, can cause relaxation, intensified sensory experience, paranoia, anxiety, and injected conjunctiva. Withdrawal symptoms may include insomnia, reduced appetite, and irritability.

      Hallucinogens, such as LSD, can cause perceptual changes, pupillary dilation, tachycardia, sweating, palpitations, tremors, and incoordination. There is no recognised withdrawal syndrome for hallucinogens.

      Ketamine, also known as Vitamin K, Super K, Special K, of donkey dust, can cause euphoria, dissociation, ataxia, and hallucinations. There is no recognised withdrawal syndrome for ketamine.

      Explanation:

      Project MATCH: Investigating the Best Treatment for Alcoholics

      Project MATCH was an extensive research study that spanned over 8 years and aimed to determine which types of alcoholics respond best to which forms of treatment. The study investigated three types of treatment: Cognitive Behavioural Coping Skills Therapy, Motivational Enhancement Therapy, and Twelve-Step Facilitation Therapy.

      Cognitive Behavioural Coping Skills Therapy focused on correcting poor self-esteem and distorted, negative, and self-defeating thinking. Motivational Enhancement Therapy helped clients become aware of and build on personal strengths that could improve their readiness to quit. Twelve-Step Facilitation Therapy was designed to familiarize patients with the AA philosophy and encourage participation.

      After the study, it was concluded that patient-treatment matching is not necessary in alcoholism treatment because the three techniques are equally effective. This study provides valuable insights into the treatment of alcoholism and can help healthcare professionals make informed decisions about the best treatment options for their patients.

      Explanation:

      Wernicke’s Encephalopathy: Symptoms, Causes, and Treatment

      Wernicke’s encephalopathy is a serious condition that is characterized by confusion, ophthalmoplegia, and ataxia. However, the complete triad is only present in 10% of cases, which often leads to underdiagnosis. The condition results from prolonged thiamine deficiency, which is commonly seen in people with alcohol dependency, but can also occur in other conditions such as anorexia nervosa, malignancy, and AIDS.

      The onset of Wernicke’s encephalopathy is usually abrupt, but it may develop over several days to weeks. The lesions occur in a symmetrical distribution in structures surrounding the third ventricle, aqueduct, and fourth ventricle. The mammillary bodies are involved in up to 80% of cases, and atrophy of these structures is specific for Wernicke’s encephalopathy.

      Treatment involves intravenous thiamine, as oral forms of B1 are poorly absorbed. IV glucose should be avoided when thiamine deficiency is suspected as it can precipitate of exacerbate Wernicke’s. With treatment, ophthalmoplegia and confusion usually resolve within days, but the ataxia, neuropathy, and nystagmus may be prolonged of permanent.

      Untreated cases of Wernicke’s encephalopathy can lead to Korsakoff’s syndrome, which is characterized by memory impairment associated with confabulation. The mortality rate associated with Wernicke’s encephalopathy is 10-20%, making early diagnosis and treatment crucial.

    • What drug is classified as a class B substance in the UK?

      Your Answer: Benzodiazepines

      Correct Answer: Mephedrone

      Explanation:

      Drug Misuse (Law and Scheduling)

      The Misuse of Drugs Act (1971) regulates the possession and supply of drugs, classifying them into three categories: A, B, and C. The maximum penalty for possession varies depending on the class of drug, with Class A drugs carrying a maximum sentence of 7 years.

      The Misuse of Drugs Regulations 2001 further categorizes controlled drugs into five schedules. Schedule 1 drugs are considered to have no therapeutic value and cannot be lawfully possessed of prescribed, while Schedule 2 drugs are available for medical use but require a controlled drug prescription. Schedule 3, 4, and 5 drugs have varying levels of restrictions and requirements.

      It is important to note that a single drug can have multiple scheduling statuses, depending on factors such as strength and route of administration. For example, morphine and codeine can be either Schedule 2 of Schedule 5.

      Overall, the Misuse of Drugs Act and Regulations aim to regulate and control the use of drugs in the UK, with the goal of reducing drug misuse and related harm.

    Incorrect

    • Which of the following symptoms is uncommon in cases of alcohol withdrawal?

      Your Answer: Hyperhidrosis

      Correct Answer: Sedation

      Explanation:

      Alcohol withdrawal is characterized by overactivity of the autonomic nervous system, resulting in symptoms such as agitation, tremors, sweating, nausea, vomiting, fever, and tachycardia. These symptoms typically begin 3-12 hours after drinking stops, peak between 24-48 hours, and can last up to 14 days. Withdrawal seizures may occur before blood alcohol levels reach zero, and a small percentage of people may experience delirium tremens (DT), which can be fatal if left untreated. Risk factors for DT include abnormal liver function, old age, severity of withdrawal symptoms, concurrent medical illness, heavy alcohol use, self-detox, previous history of DT, low potassium, low magnesium, and thiamine deficiency.

      Pharmacologically assisted detox is often necessary for those who regularly consume more than 15 units of alcohol per day, and inpatient detox may be needed for those who regularly consume more than 30 units per day. The Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA-Ar) can be used to assess the severity of withdrawal symptoms and guide treatment decisions. Benzodiazepines are the mainstay of treatment, as chronic alcohol exposure results in decreased overall brain excitability and compensatory decrease of GABA-A neuroreceptor response to GABA. Chlordiazepoxide is a good first-line agent, while oxazepam, temazepam, and lorazepam are useful in patients with liver disease. Clomethiazole is effective but carries a high risk of respiratory depression and is not recommended. Thiamine should be offered to prevent Wernicke’s encephalopathy, and long-acting benzodiazepines can be used as prophylaxis for withdrawal seizures. Haloperidol is the treatment of choice if an antipsychotic is required.

      Problem Gambling: Screening and Interventions

      Problem gambling, also known as pathological gambling, refers to gambling that causes harm to personal, family, of recreational pursuits. The prevalence of problem gambling in adults ranges from 7.3% to 0.7%, while in psychiatric patients, it ranges from 6% to 12%. Problem gambling typically starts in early adolescence in males and runs a chronic, progressive course with periods of abstinence and relapses.

      Screening for problem gambling is done using various tools, including the NODS-CLiP and the South Oaks Gambling Screen (SOGS). Brief interventions have been successful in decreasing gambling, with motivational enhancement therapy (MET) being the most effective. Pharmacological interventions, such as selective serotonin reuptake inhibitors (SSRIs), naltrexone, and mood stabilizers, have also been effective, but the choice of drug depends on the presence of comorbidity. Psychological interventions, particularly cognitive-behavioral treatments, show promise, but long-term follow-up and high drop-out rates are major limitations. Studies comparing psychological and pharmacological interventions are needed.

Your consultant asks you to convert this to diazepam so that the patient can be slowly weaned off benzodiazepines. Select the correct equivalent dose of diazepam:

      Your Answer: 20mg QDS

      Correct Answer: 40mg QDS

      Explanation:

      Benzodiazepines and Addiction

      Benzodiazepines are known to be addictive and should only be prescribed as a hypnotic or anxiolytic for a maximum of 4 weeks. Withdrawal symptoms can be physical of psychological, including stiffness, weakness, GI disturbance, paraesthesia, flu-like symptoms, visual disturbance, anxiety, insomnia, nightmares, depersonalisation, decreased memory and concentration, delusions, and hallucinations. Patients who wish to withdraw from short-acting benzodiazepines should first be converted to diazepam, which has a longer half-life and produces less severe withdrawal. The table provides approximate equivalent doses for different benzodiazepines. These guidelines are from the Maudsley Guidelines 10th Edition.

      Your Answer: Diazepam

      Explanation:

      Urine drug screens typically aim to identify nordiazepam of oxazepam, which are metabolites of diazepam. However, benzodiazepines such as alprazolam, lorazepam, and clonazepam, which are commonly prescribed and abused, do not produce these metabolites and may not be detected by many urine drug immunoassays.

      Explanation:

      Suboxone vs. Subutex: What’s the Difference?

      Suboxone and Subutex are both medications used to treat opioid addiction. However, there are some key differences between the two.

      Suboxone is a combination of buprenorphine and naloxone. The naloxone is added to prevent people from injecting the medication, as this was a common problem with pure buprenorphine tablets. If someone tries to inject Suboxone, the naloxone will cause intense withdrawal symptoms. However, if the tablet is swallowed as directed, the naloxone is not absorbed by the gut and does not cause any problems.

      Subutex, on the other hand, contains only buprenorphine and does not include naloxone. This means that it may be more likely to be abused by injection, as there is no deterrent to prevent people from doing so.

      Overall, both Suboxone and Subutex can be effective treatments for opioid addiction, but Suboxone may be a safer choice due to the addition of naloxone.

      Your Answer: Mean corpuscular volume is a useful method of monitoring abstinence

      Correct Answer: Gamma-glutamyltransferase (GGT) levels return toward normal within days to weeks of stopping drinking

      Explanation:

      A diagnosis of alcohol use disorder only requires the presence of two or more of the 11 elements, including withdrawal and recurrent alcohol use in physically hazardous situations. Ongoing craving for alcohol does not prevent someone from being considered in sustained remission, which is defined as not meeting any criteria for alcohol use disorder for 12 months of longer, except for craving. Monitoring abstinence can be done using state markers such as GGT and CDT levels, which return to normal within days to weeks of stopping drinking, but MCV is a poor method due to the long half-life of red blood cells. Increases in GGT and CDT levels over time may indicate a return to heavy drinking.

      Alcohol Dependence Syndrome: ICD-11 and DSM 5 Criteria

      The criteria for diagnosing alcohol dependence syndrome in the ICD-11 and DSM 5 are quite similar, as both are based on the original concept developed by Edwards and Gross in 1976. The original concept had seven elements, including narrowing of the drinking repertoire, salience of drink seeking behavior, tolerance, withdrawal symptoms, relief of withdrawal by further drinking, compulsion to drink, and rapid reinstatement of symptoms after a period of abstinence.

      The DSM-5 Alcohol Use Disorder criteria include a problematic pattern of alcohol use leading to clinically significant impairment of distress, as manifested by at least two of the following occurring within a 12-month period. These include taking alcohol in larger amounts of over a longer period than intended, persistent desire of unsuccessful efforts to cut down of control alcohol use, spending a great deal of time in activities necessary to obtain alcohol, craving of a strong desire of urge to use alcohol, recurrent alcohol use resulting in a failure to fulfill major role obligations, continued alcohol use despite having persistent or recurrent social of interpersonal problems, giving up of reducing important social, occupational, of recreational activities due to alcohol use, recurrent alcohol use in physically hazardous situations, and continued alcohol use despite knowledge of having a persistent or recurrent physical or psychological problem caused or exacerbated by alcohol. Tolerance and withdrawal symptoms are also included in the criteria.

      The ICD-11 Alcohol Dependence criteria include a pattern of recurrent episodic of continuous use of alcohol with evidence of impaired regulation of alcohol use, manifested by impaired control over alcohol use, increasing precedence of alcohol use over other aspects of life, and physiological features indicative of neuroadaptation to the substance, including tolerance to the effects of alcohol of a need to use increasing amounts of alcohol to achieve the same effect, withdrawal symptoms following cessation of reduction in use of alcohol, of repeated use of alcohol of pharmacologically similar substances to prevent of alleviate withdrawal symptoms. The features of dependence are usually evident over a period of at least 12 months, but the diagnosis may be made if use is continuous for at least 3 months.

    Correct

    • What is the maintenance treatment used for individuals with opioid dependence syndrome?

      Your Answer: Buprenorphine

      Explanation:

      Synthetic opioids like methadone and buprenorphine are utilized as a replacement for heroin. Alpha2 adrenergic agonists such as clonidine and lofexidine are employed in detox settings to alleviate a range of opioid withdrawal symptoms.

      Opioid Maintenance Therapy and Detoxification

      Withdrawal symptoms can occur after as little as 5 days of regular opioid use. Short-acting opioids like heroin have acute withdrawal symptoms that peak in 32-72 hours and last for 3-5 days. Longer-acting opioids like methadone have acute symptoms that peak at day 4-6 and last for 10 days. Buprenorphine withdrawal lasts up to 10 days and includes symptoms like myalgia, anxiety, and increased drug craving.

      Opioids affect the brain through opioid receptors, with the µ receptor being the main target for opioids. Dopaminergic cells in the ventral tegmental area produce dopamine, which is released into the nucleus accumbens upon stimulation of µ receptors, producing euphoria and reward. With repeat opioid exposure, µ receptors become less responsive, causing dysphoria and drug craving.

      Methadone and buprenorphine are maintenance-oriented treatments for opioid dependence. Methadone is a full agonist targeting µ receptors, while buprenorphine is a partial agonist targeting µ receptors and a partial k agonist of functional antagonist. Naloxone and naltrexone are antagonists targeting all opioid receptors.

      Methadone is preferred over buprenorphine for detoxification, and ultra-rapid detoxification should not be offered. Lofexidine may be considered for mild of uncertain dependence. Clonidine and dihydrocodeine should not be used routinely in opioid detoxification. The duration of detoxification should be up to 4 weeks in an inpatient setting and up to 12 weeks in a community setting.

      Pregnant women dependent on opioids should use opioid maintenance treatment rather than attempt detoxification. Methadone is preferred over buprenorphine, and transfer to buprenorphine during pregnancy is not advised. Detoxification should only be considered if appropriate for the women’s wishes, circumstances, and ability to cope. Methadone or buprenorphine treatment is not a contraindication to breastfeeding.

      Your Answer: Decreased homocysteine levels are associated with increased risk of alcohol withdrawal seizures in alcohol-dependent patients

      Correct Answer: Home detoxification is usually complete within 5-9 days

      Explanation:

      Alcohol detoxification can be done at home of in an inpatient setting. Studies have shown that there is no significant difference between the two methods, but inpatient detox is much more expensive. However, inpatient detox is recommended for patients who have a high risk of seizures during alcohol withdrawal, which occurs in 5-10% of patients. Age, prolactin, blood alcohol concentration on admission, and elevated homocysteine levels are all risk factors for seizures, with the latter being the strongest predictor. Chronic alcohol intake can lead to elevated homocysteine levels due to impaired metabolism from B12 and folate deficiency.

      Your Answer: For hallucinations associated with delirium tremens, haloperidol is the preferred antipsychotic

      Explanation:

      For individuals experiencing delirium tremens, the initial treatment option should be oral lorazepam. If symptoms persist of the individual declines oral medication, alternative options such as parenteral lorazepam of haloperidol should be offered, as recommended by NICE CG100.

      Detection times vary from person to person, and the approximate drug detection time in urine can be found in a table provided by Nelson (2016). False positives can occur due to cross-reactivity, as illustrated by Moeller (2017). Clinicians should be aware of the limitations of urine drug tests and the potential for manipulation.

      Wernicke’s Encephalopathy: Symptoms, Causes, and Treatment

      Wernicke’s encephalopathy is a serious condition that is characterized by confusion, ophthalmoplegia, and ataxia. However, the complete triad is only present in 10% of cases, which often leads to underdiagnosis. The condition results from prolonged thiamine deficiency, which is commonly seen in people with alcohol dependency, but can also occur in other conditions such as anorexia nervosa, malignancy, and AIDS.

      The onset of Wernicke’s encephalopathy is usually abrupt, but it may develop over several days to weeks. The lesions occur in a symmetrical distribution in structures surrounding the third ventricle, aqueduct, and fourth ventricle. The mammillary bodies are involved in up to 80% of cases, and atrophy of these structures is specific for Wernicke’s encephalopathy.

      Treatment involves intravenous thiamine, as oral forms of B1 are poorly absorbed. IV glucose should be avoided when thiamine deficiency is suspected as it can precipitate of exacerbate Wernicke’s. With treatment, ophthalmoplegia and confusion usually resolve within days, but the ataxia, neuropathy, and nystagmus may be prolonged of permanent.

      Untreated cases of Wernicke’s encephalopathy can lead to Korsakoff’s syndrome, which is characterized by memory impairment associated with confabulation. The mortality rate associated with Wernicke’s encephalopathy is 10-20%, making early diagnosis and treatment crucial.
