What is a known factor that can lead to inaccurate positive results for amphetamine on drug screening tests?
Your Answer: Quetiapine
Correct Answer: Atomoxetine
Explanation: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.

What is a true statement about quitting smoking?
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.

In the UK, what is the schedule classification for non-benzodiazepine hypnotics such as zopiclone?
Your Answer:
Correct Answer: 4
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.

A 42-year-old woman has been struggling with a gambling addiction for the past decade and has a diagnosis of gambling disorder. She has just completed a residential treatment program for her addiction under your supervision. She is determined to stay away from gambling but is concerned that she may give in to her urges. She is not confident that she can resist the temptation to gamble occasionally. What intervention should you avoid in this situation?
Your Answer:
Correct Answer: Disulfiram
Explanation:Disulfiram is not recommended in this case due to its ability to inhibit acetaldehyde dehydrogenase and potentially cause a severe reaction if the patient consumes any alcohol. Acamprosate is the preferred medication for reducing cravings, but other options such as naltrexone, cognitive-behavioral therapy, and participation in a 12-step program have also been proven effective in maintaining abstinence after detoxification.

What is the recommended management approach for Wernicke's encephalopathy that is accompanied by petechial hemorrhages?
Your Answer:
Correct Answer: Intravenous vitamin B1
Explanation:Standard practice should be followed when petechial hemorrhages are observed in an MRI of a patient with Wernicke’s, as they are a typical characteristic of the disease.
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.

A 30 year old man presents to his primary care physician with complaints of insomnia, anxiety, tremors, and confusion. He is an avid bodybuilder and reports that he had been taking a supplement to enhance his muscle growth. He explains that he had been using a clear liquid provided by a friend. What is the most likely cause of his symptoms?
Your Answer:
Correct Answer: Gamma Butyrolactone
Explanation:The indications are in line with the effects of discontinuing GBL use, which is frequently utilized by individuals in the bodybuilding community due to its perceived ability to aid in muscle growth.
New Psychoactive Substances, previously known as ‘legal highs’, are synthetic compounds designed to mimic the effects of traditional illicit drugs. They became popular due to their ability to avoid legislative control, but the introduction of the Psychoactive Substances Act 2016 changed this. There is no standard for clinical classification, but some common legal highs include Mephedrone, Piperazines, GBL, Synthetic cannabinoids, and Benzofuran compounds. These substances have effects similar to ecstasy, amphetamines, and cannabis, and are classified as either Class B of Class C drugs in the UK.

What is the maintenance treatment used for individuals with opioid dependence syndrome?
Your Answer:
Correct 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.

Which substance withdrawal is linked to symptoms of hypersomnia, hyperphagia, and irritability?
Your Answer:
Correct Answer: Amphetamine
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.

What is a known factor that can lead to inaccurate positive results for benzodiazepines on drug screening tests?
Your Answer:
Correct Answer: Sertraline
Explanation: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.

In chronic opiate use, which effect is most likely to continue over time?
Your Answer:
Correct Answer: Constipation
Explanation: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.

Which statement about Korsakoff's psychosis is incorrect?
Your Answer:
Correct Answer: New memories are unaffected
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 principle is not included in motivational interviewing?
Your Answer:
Correct Answer: Encourage confrontation
Explanation:Motivational interviewing aims to prevent conflict and necessitates the therapist to maintain a neutral stance.
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.

What methods have been proven to be successful in addressing problem gambling?
Your Answer:
Correct Answer: Naltrexone
Explanation: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.

A 40-year-old man visits his doctor requesting to discontinue his long-term use of diazepam. If he discontinues the medication, what is the most probable outcome he will encounter?
Your Answer:
Correct Answer: Insomnia
Explanation:The most prevalent indication of benzodiazepine withdrawal is insomnia.
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.

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:
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.

What combination of substances is included in Suboxone?
Your Answer:
Correct Answer: Naloxone and buprenorphine
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.

What factors are known to contribute to false positive outcomes for cannabis on drug screening tests?
Your Answer:
Correct Answer: Efavirenz, promethazine, and ibuprofen
Explanation: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.

A woman reporting vivid dreams, increased sleep and an increased appetite, is most likely to be experiencing which of the following?
Your Answer:
Correct Answer: Cocaine withdrawal
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.

What is the accurate statement about the issue of alcohol misuse in the United Kingdom?
Your Answer:
Correct Answer: The highest levels of binge drinking occur in people aged 16-24
Explanation:Prevalence of Substance Misuse, with a Focus on Alcohol Misuse
Alcohol misuse is a major issue, particularly in the UK, where it is among the highest rates in Europe. Men are more likely to experience both alcohol dependence and binge drinking than women. Specifically, 6% of men and 2% of women experience alcohol dependence, while 21% of men and 9% of women engage in binge drinking. It is worth noting that this figure contradicts the findings from the NPMS in 2000.
