    Correct

    • What is the preferred sedative for patients who have significant liver damage?

      Your Answer: Oxazepam

      Explanation:

      Sedatives and Liver Disease

      Sedatives are commonly used for their calming effects, but many of them are metabolized in the liver. Therefore, caution must be taken when administering sedatives to patients with liver disease. The Maudsley Guidelines recommend using low doses of the following sedatives in patients with hepatic impairment: lorazepam, oxazepam, temazepam, and zopiclone. It is important to note that zopiclone should also be used with caution and at low doses in this population. Proper management of sedative use in patients with liver disease can help prevent further damage to the liver and improve overall patient outcomes.

    • What is a true statement about eating disorders?

      Your Answer: Modified dialectical behaviour therapy should not be offered to adults with binge eating disorder

      Correct Answer: Psychological treatments for binge eating disorder have a limited effect on body weight

      Explanation:

      The 2017 NICE Guidelines advise clinicians to inform individuals with binge eating disorder that psychological treatments focused on addressing binge eating may not have a significant impact on body weight and that weight loss is not the primary goal of therapy. However, it is important to clarify that while CBT-ED does not specifically target weight loss, it can lead to weight reduction in the long run by addressing binge eating behaviors.

      Eating Disorders: NICE Guidelines

      Anorexia:
      For adults with anorexia nervosa, consider individual eating-disorder-focused cognitive behavioural therapy (CBT-ED), Maudsley Anorexia Nervosa Treatment for Adults (MANTRA), of specialist supportive clinical management (SSCM). If these are not acceptable, contraindicated, of ineffective, consider eating-disorder-focused focal psychodynamic therapy (FPT). For children and young people, consider anorexia-nervosa-focused family therapy (FT-AN) of individual CBT-ED. Do not offer medication as the sole treatment.

      Bulimia:
      For adults, the first step is an evidence-based self-help programme. If this is not effective, consider individual CBT-ED. For children and young people, offer bulimia-nervosa-focused family therapy (FT-BN) of individual CBT-ED. Do not offer medication as the sole treatment.

      Binge Eating Disorder:
      The first step is a guided self-help programme. If this is not effective, offer group of individual CBT-ED. For children and young people, offer the same treatments recommended for adults. Do not offer medication as the sole treatment.

      Advice for those with eating disorders:
      Encourage people with an eating disorder who are vomiting to avoid brushing teeth immediately after vomiting, rinse with non-acid mouthwash, and avoid highly acidic foods and drinks. Advise against misusing laxatives of diuretics and excessive exercise.

      Additional points:
      Do not offer physical therapy as part of treatment. Consider bone mineral density scans after 1 year of underweight in children and young people, of 2 years in adults. Do not routinely offer oral of transdermal oestrogen therapy to treat low bone mineral density in children of young people with anorexia nervosa. Consider transdermal 17-β-estradiol of bisphosphonates for women with anorexia nervosa.

      Note: These guidelines are taken from NICE guidelines 2017.

    Incorrect

    • A woman who has had bipolar affective disorder for the past 3 years presents with an episode of mania. She is admitted to hospital to the ward on which you are the resident doctor. She has been taking aripiprazole 20 mg for the past three years and has been compliant. What would be your recommendation in this case?

      Your Answer: Stop aripiprazole and start lithium

      Correct Answer: Increase the dose of aripiprazole

      Explanation:

      Before implementing any management plan, it is crucial to verify adherence and confirm that the dosage is suitable. In cases of mania, the maximum dosage of aripiprazole can be raised to 30mg per day.

      Bipolar Disorder: Diagnosis and Management

      Bipolar disorder is a lifelong condition characterized by episodes of mania or hypomania and episodes of depressed mood. The peak age of onset is 15-19 years, and the lifetime prevalence of bipolar I disorders is estimated to be around 2.1%. The diagnosis of bipolar disorder is based on the presence of manic or hypomanic episodes, which are characterized by elevated of expansive mood, rapid speech, and increased activity of energy. Psychotic symptoms, such as delusions and hallucinations, may also be present.

      Bipolar depression differs from unipolar depression in several ways, including more rapid onset, more frequent episodes, and shorter duration. Rapid cycling is a qualifier that can be applied to bipolar I of bipolar II disorder and is defined as the presence of at least four mood episodes in the previous 12 months that meet the criteria for a manic, hypomanic, of major depressive episode.

      The management of bipolar disorder involves acute and long-term interventions. Acute management of mania or hypomania may involve stopping antidepressants and offering antipsychotics of mood stabilizers. Long-term management may involve psychological interventions and pharmacological treatments such as lithium, valproate, of olanzapine.

      It is important to note that valproate should not be offered to women of girls of childbearing potential for long-term bipolar disorder unless other options are ineffective of not tolerated and a pregnancy prevention program is in place. Aripiprazole is recommended as an option for treating moderate to severe manic episodes in adolescents with bipolar I disorder.

      Overall, the diagnosis and management of bipolar disorder require a comprehensive approach that takes into account the individual’s symptoms, history, and preferences.

    • What is the term used to describe a test that initially appears to measure what it is intended to measure?

      Your Answer: Good face validity

      Explanation:

      A test that seems to measure what it is intended to measure has strong face validity.

      Validity in statistics refers to how accurately something measures what it claims to measure. There are two main types of validity: internal and external. Internal validity refers to the confidence we have in the cause and effect relationship in a study, while external validity refers to the degree to which the conclusions of a study can be applied to other people, places, and times. There are various threats to both internal and external validity, such as sampling, measurement instrument obtrusiveness, and reactive effects of setting. Additionally, there are several subtypes of validity, including face validity, content validity, criterion validity, and construct validity. Each subtype has its own specific focus and methods for testing validity.

    Incorrect

    • A new antihypertensive medication is trialled for adults with high blood pressure. There are 500 adults in the control group and 300 adults assigned to take the new medication. After 6 months, 200 adults in the control group had high blood pressure compared to 30 adults in the group taking the new medication. What is the relative risk reduction?

      Your Answer: 30%

      Correct Answer: 75%

      Explanation:

      The RRR (Relative Risk Reduction) is calculated by dividing the ARR (Absolute Risk Reduction) by the CER (Control Event Rate). The CER is determined by dividing the number of control events by the total number of participants, which in this case is 200/500 of 0.4. The EER (Experimental Event Rate) is determined by dividing the number of events in the experimental group by the total number of participants, which in this case is 30/300 of 0.1. The ARR is calculated by subtracting the EER from the CER, which is 0.4 – 0.1 = 0.3. Finally, the RRR is calculated by dividing the ARR by the CER, which is 0.3/0.4 of 0.75 (of 75%).

      Measures of Effect in Clinical Studies

      When conducting clinical studies, we often want to know the effect of treatments of exposures on health outcomes. Measures of effect are used in randomized controlled trials (RCTs) and include the odds ratio (of), risk ratio (RR), risk difference (RD), and number needed to treat (NNT). Dichotomous (binary) outcome data are common in clinical trials, where the outcome for each participant is one of two possibilities, such as dead of alive, of clinical improvement of no improvement.

      To understand the difference between of and RR, it’s important to know the difference between risks and odds. Risk is a proportion that describes the probability of a health outcome occurring, while odds is a ratio that compares the probability of an event occurring to the probability of it not occurring. Absolute risk is the basic risk, while risk difference is the difference between the absolute risk of an event in the intervention group and the absolute risk in the control group. Relative risk is the ratio of risk in the intervention group to the risk in the control group.

      The number needed to treat (NNT) is the number of patients who need to be treated for one to benefit. Odds are calculated by dividing the number of times an event happens by the number of times it does not happen. The odds ratio is the odds of an outcome given a particular exposure versus the odds of an outcome in the absence of the exposure. It is commonly used in case-control studies and can also be used in cross-sectional and cohort study designs. An odds ratio of 1 indicates no difference in risk between the two groups, while an odds ratio >1 indicates an increased risk and an odds ratio <1 indicates a reduced risk.

  • Question 7 - What benefit does conducting a cost-effectiveness analysis offer? ...

    Correct

    • What benefit does conducting a cost-effectiveness analysis offer?

      Your Answer: Outcomes are expressed in natural units that are clinically meaningful

      Explanation:

      A major benefit of using cost-effectiveness analysis is that the results are immediately understandable, such as the cost per year of remission from depression. When conducting economic evaluations, costs are typically estimated in a standardized manner across different types of studies, taking into account direct costs (e.g. physician time), indirect costs (e.g. lost productivity from being absent from work), and future costs (e.g. developing diabetes as a result of treatment with clozapine). The primary variation between economic evaluations lies in how outcomes are evaluated.

      Methods of Economic Evaluation

      There are four main methods of economic evaluation: cost-effectiveness analysis (CEA), cost-benefit analysis (CBA), cost-utility analysis (CUA), and cost-minimisation analysis (CMA). While all four methods capture costs, they differ in how they assess health effects.

      Cost-effectiveness analysis (CEA) compares interventions by relating costs to a single clinical measure of effectiveness, such as symptom reduction of improvement in activities of daily living. The cost-effectiveness ratio is calculated as total cost divided by units of effectiveness. CEA is typically used when CBA cannot be performed due to the inability to monetise benefits.

      Cost-benefit analysis (CBA) measures all costs and benefits of an intervention in monetary terms to establish which alternative has the greatest net benefit. CBA requires that all consequences of an intervention, such as life-years saved, treatment side-effects, symptom relief, disability, pain, and discomfort, are allocated a monetary value. CBA is rarely used in mental health service evaluation due to the difficulty in converting benefits from mental health programmes into monetary values.

      Cost-utility analysis (CUA) is a special form of CEA in which health benefits/outcomes are measured in broader, more generic ways, enabling comparisons between treatments for different diseases and conditions. Multidimensional health outcomes are measured by a single preference- of utility-based index such as the Quality-Adjusted-Life-Years (QALY). QALYs are a composite measure of gains in life expectancy and health-related quality of life. CUA allows for comparisons across treatments for different conditions.

      Cost-minimisation analysis (CMA) is an economic evaluation in which the consequences of competing interventions are the same, and only inputs, i.e. costs, are taken into consideration. The aim is to decide the least costly way of achieving the same outcome.

      Costs in Economic Evaluation Studies

      There are three main types of costs in economic evaluation studies: direct, indirect, and intangible. Direct costs are associated directly with the healthcare intervention, such as staff time, medical supplies, cost of travel for the patient, childcare costs for the patient, and costs falling on other social sectors such as domestic help from social services. Indirect costs are incurred by the reduced productivity of the patient, such as time off work, reduced work productivity, and time spent caring for the patient by relatives. Intangible costs are difficult to measure, such as pain of suffering on the part of the patient.

    Incorrect

    • A study examines the likelihood of stroke in middle-aged patients prescribed antipsychotic medication. Group A receives standard treatment, and after 5 years, 20 out of 100 patients experience a stroke. Group B receives standard treatment plus a new drug intended to decrease the risk of stroke. After 5 years, 10 out of 60 patients have a stroke. What are the chances of having a stroke while taking the new drug compared to the chances of having a stroke in those receiving standard treatment?

      Your Answer: 0.83

      Correct Answer: 0.8

      Explanation:

      If the odds ratio is less than 1, it means that the likelihood of experiencing a stroke is lower for individuals who are taking the new drug compared to those who are receiving the usual treatment.

The odds ratio is the odds of an outcome given a particular exposure versus the odds of an outcome in the absence of the exposure. It is commonly used in case-control studies and can also be used in cross-sectional and cohort study designs. An odds ratio of 1 indicates no difference in risk between the two groups, while an odds ratio >1 indicates an increased risk and an odds ratio <1 indicates a reduced risk.

    • What is the approach of the criminal justice system towards managing young individuals?

      Your Answer: A Local Child Curfew refers to a child being placed under the supervision of a youth offending team

      Correct Answer: A Child Safety Order can be imposed for a child under 10 who breaks the law

      Explanation:

      Criminal Responsibility and Age Limits

      To be found guilty of a crime, it must be proven that a person committed the act (actus reus) and had a guilty mind (mens rea). In England and Wales, children under the age of 10 cannot be held criminally responsible for their actions and cannot be arrested or charged with a crime. Instead, they may face other punishments such as a Local Child Curfew of a Child Safety Order. Children between the ages of 10 and 17 can be arrested and taken to court, but are treated differently from adults and may be dealt with by youth courts, given different sentences, and sent to special secure centers for young people. Young people aged 18 are treated as adults by the law.

      Not Guilty by Reason of Insanity and Other Defenses

      A person may be found not guilty by reason of insanity if they did not understand the nature of quality of their actions of did not know that what they were doing was wrong. Automatism is a defense used when the act is believed to have occurred unconsciously, either from an external cause (sane automatism) of an internal cause (insane automatism). Diminished responsibility is a defense used only in the defense of murder and allows for a reduction of the normal life sentence to manslaughter.

      Explanation:

      Paroxetine Use During Pregnancy: Is it Safe?

      Prescribing medication during pregnancy and breastfeeding is challenging due to the potential risks to the fetus of baby. No psychotropic medication has a UK marketing authorization specifically for pregnant of breastfeeding women. Women are encouraged to breastfeed unless they are taking carbamazepine, clozapine, of lithium. The risk of spontaneous major malformation is 2-3%, with drugs accounting for approximately 5% of all abnormalities. Valproate and carbamazepine are associated with an increased risk of neural tube defects, and lithium is associated with cardiac malformations. Benzodiazepines are associated with oral clefts and floppy baby syndrome. Antidepressants have been linked to preterm delivery and congenital malformation, but most findings have been inconsistent. TCAs have been used widely without apparent detriment to the fetus, but their use in the third trimester is known to produce neonatal withdrawal effects. Sertraline appears to result in the least placental exposure among SSRIs. MAOIs should be avoided in pregnancy due to a suspected increased risk of congenital malformations and hypertensive crisis. If a pregnant woman is stable on an antipsychotic and likely to relapse without medication, she should continue the antipsychotic. Depot antipsychotics should not be offered to pregnant of breastfeeding women unless they have a history of non-adherence with oral medication. The Maudsley Guidelines suggest specific drugs for use during pregnancy and breastfeeding. NICE CG192 recommends high-intensity psychological interventions for moderate to severe depression and anxiety disorders. Antipsychotics are recommended for pregnant women with mania of psychosis who are not taking psychotropic medication. Promethazine is recommended for insomnia.

      Generalised Anxiety Disorder: Symptoms and Diagnosis

      Generalised anxiety disorder is a condition characterized by persistent symptoms of anxiety that last for several months and occur on most days. The symptoms can be either general apprehension of excessive worry about multiple everyday events, such as family, health, finances, and work of school. In addition to these symptoms, individuals with generalised anxiety disorder may experience muscular tension, motor restlessness, sympathetic autonomic overactivity, nervousness, difficulty concentrating, irritability, of sleep disturbance.

      To diagnose generalised anxiety disorder, healthcare professionals look for specific essential features. These include marked symptoms of anxiety that are not restricted to any particular environmental circumstance, and are accompanied by additional characteristic symptoms such as muscle tension, autonomic overactivity, nervousness, difficulty concentrating, irritability, and sleep disturbances. The symptoms must persist for at least several months, for more days than not, and cannot be better accounted for by another mental disorder of medical condition. The symptoms must also result in significant distress of impairment in personal, family, social, educational, occupational, of other important areas of functioning.

      Explanation:

      The duration of cannabis in the system may vary, but it typically lasts for weeks rather than just a few hours of days. However, if cannabis is used only once, it may only be detectable for a period of 6-24 hours.

      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 most frequently observed neuro-ophthalmic symptom of Wernicke's?

      Your Answer: Horizontal gaze-evoked nystagmus

      Explanation:

      Wernicke’s disease affects both the efferent and afferent visual systems, resulting in various neuro-ophthalmic manifestations. The ocular motor abnormalities range from mild to severe, with horizontal gaze-evoked nystagmus being the most common ophthalmic sign. Bilateral abducens palsy and conjugate gaze palsies, mostly horizontal, are also frequently observed. Although complete ophthalmoplegia is often mentioned as part of the classic triad, it is a rare occurrence in Wernicke’s disease. Unilateral internuclear ophthalmoplegia is rarely reported, and bilateral cases are exceptionally rare, with only one case found.

      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.

  • Question 17 - What is the main focus of behavioural activation therapy? ...

    Correct

    • What is the main focus of behavioural activation therapy?

      Your Answer: Depression

      Explanation:

      Understanding Behavioural Activation Therapy for Depression

      Behavioural activation therapy is a formal treatment for depression that emphasizes activity scheduling to encourage patients to approach activities they are avoiding. Unlike traditional cognitive therapy, it involves less cognitive therapy and is easier to train staff in its use. The therapy was introduced by Martell in 2001 and has two primary focuses: the use of avoided activities as a guide for activity scheduling and functional analysis of cognitive processes that involve avoidance.

      Behavioural activation theory suggests that when people become depressed, many of their activities function as avoidance and escape from aversive thoughts, feelings, of external situations. As a result, someone with depression engages less frequently in pleasant of satisfying activities and obtains less positive reinforcement than someone without depression. To address this, the patient is encouraged to identify activities and problems that they avoid and to establish valued directions to be followed. These are set out on planned timetables (activity schedules).

      In behavioural activation therapy, therapists do not engage in the content of the patient’s thinking. Instead, they use functional analysis to focus on the context and process of the individual’s response. The most common cognitive responses are rumination, fusion, and self-attack. A typical session has a structured agenda to review homework and progress towards goals, discuss feedback on the previous session, and focus on one of two specific issues. The number of sessions required to treat depression is typically between 12 and 24.

    • What is the percentage of individuals with alcohol dependence who have attempted of completed suicide at some point in their lifetime?

      Your 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.

      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 is the appropriate interpretation of a standardised mortality ratio of 120% (95% CI 90-130) for a cohort of patients diagnosed with antisocial personality disorder?

      Your Answer: The result is not statistically significant

      Explanation:

      The statistical significance of the result is questionable as the confidence interval encompasses values below 100. This implies that there is a possibility that the actual value could be lower than 100, which contradicts the observed value of 120 indicating a rise in mortality in this population.

      Calculation of Standardised Mortality Ratio (SMR)

      To calculate the SMR, age and sex-specific death rates in the standard population are obtained. An estimate for the number of people in each category for both the standard and study populations is needed. The number of expected deaths in each age-sex group of the study population is calculated by multiplying the age-sex-specific rates in the standard population by the number of people in each category of the study population. The sum of all age- and sex-specific expected deaths gives the expected number of deaths for the whole study population. The observed number of deaths is then divided by the expected number of deaths to obtain the SMR.

      The SMR can be standardised using the direct of indirect method. The direct method is used when the age-sex-specific rates for the study population and the age-sex-structure of the standard population are known. The indirect method is used when the age-specific rates for the study population are unknown of not available. This method uses the observed number of deaths in the study population and compares it to the number of deaths that would be expected if the age distribution was the same as that of the standard population.

      The SMR can be interpreted as follows: an SMR less than 1.0 indicates fewer than expected deaths in the study population, an SMR of 1.0 indicates the number of observed deaths equals the number of expected deaths in the study population, and an SMR greater than 1.0 indicates more than expected deaths in the study population (excess deaths). It is sometimes expressed after multiplying by 100.
