Question 1
Correct
-
A 26-year-old male is admitted to the Emergency Department with severe abdominal pain. He is shivering and writhing in pain on the trolley. He has a history of recurrent abdominal pain with no identifiable cause. He insists on receiving morphine for pain relief and threatens to harm himself if he does not receive it.
Upon reviewing his medical records, you observe a consistent pattern of this behavior.
What is the most probable diagnosis from the options provided?Your Answer: Malingering
Explanation:This is a challenging situation as the individual may be experiencing opiate withdrawal due to their history of substance abuse. Nevertheless, based on the given choices, the most suitable term to describe the patient’s behavior is malingering, as they are feigning symptoms in order to obtain morphine.
Somatoform and dissociative disorders are two groups of psychiatric disorders that are characterized by physical symptoms and disruptions in the normal integration of identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, of behavior. Somatoform disorders are characterized by physical symptoms that are presumed to have a psychiatric origin, while dissociative disorders are characterized by the loss of integration between memories, identity, immediate sensations, and control of bodily movements. The ICD-11 lists two main types of somatoform disorders: bodily distress disorder and body integrity dysphoria. Dissociative disorders include dissociative neurological symptom disorder, dissociative amnesia, trance disorder, possession trance disorder, dissociative identity disorder, partial dissociative identity disorder, depersonalization-derealization disorder, and other specified dissociative disorders. The symptoms of these disorders result in significant impairment in personal, family, social, educational, occupational, of other important areas of functioning. Diagnosis of these disorders involves a thorough evaluation of the individual’s symptoms and medical history, as well as ruling out other possible causes of the symptoms.

How many months of consecutive voluntary or involuntary passage of normal feces in inappropriate places are required to meet the diagnostic criteria for encopresis in a child?
Your Answer: 6
Correct Answer: 3
Explanation:Elimination Disorders
Elimination disorders refer to conditions that affect a child’s ability to control their bladder of bowel movements. Enuresis, of lack of control over the bladder, typically occurs between the ages of 1-3, while control over the bowel usually occurs before that of the bladder for most toddlers. Toilet training can be influenced by various factors, including intellectual capacity, cultural determinants, and psychological interactions between the child and their parents.
Enuresis is characterized by involuntary voiding of urine, by day and/of by night, which is abnormal in relation to the individual’s age and is not a result of any physical abnormality. It is not normally diagnosed before age 5 and may be primary (the child never having achieved continence) of secondary. Treatment options include reassurance, enuresis alarms, and medication.
Encopresis refers to repeated stool evacuation in inappropriate places in children over the age of four. The behavior can be either involuntary of intentional and may be due to unsuccessful toilet training (primary encopresis) of occur after a period of normal bowel control (secondary encopresis). Treatment generally involves bowel clearance, prevention of impaction, and behavioral therapy.
Before a diagnosis of encopresis is made, organic causes must be excluded. Hirschsprung’s disease is a condition that results from an absence of parasympathetic ganglion cells in the rectum, colon, and sometimes the small intestine. It leads to a colonic obstruction and is diagnosed in at least half of all cases in the first year of life. It is twice as common in boys than in girls.

What is a known cause of Stevens-Johnson Syndrome?
Your Answer: Carbamazepine
Explanation:Stevens-Johnson syndrome is a rare but serious condition that affects the skin and mucous membranes. It is often caused by a reaction to medication of infection and can start with flu-like symptoms. The condition is characterized by a painful rash that spreads and blisters, leading to the shedding of the top layer of affected skin. Hospitalization is usually required as it is a medical emergency. Medications that have been known to cause Stevens-Johnson syndrome include lamotrigine, phenobarbital, sertraline, and certain types of NSAIDs such as meloxicam, piroxicam, and tenoxicam.
Antiepileptic drugs (AEDs) are commonly used for the treatment of epilepsy, but many of them also have mood stabilizing properties and are used for the prophylaxis and treatment of bipolar disorder. However, some AEDs carry product warnings for serious side effects such as hepatic failure, pancreatitis, thrombocytopenia, and skin reactions. Additionally, some AEDs have been associated with an increased risk of suicidal behavior and ideation.
Behavioral side-effects associated with AEDs include depression, aberrant behaviors, and the development of worsening of irritability, impulsivity, anger, hostility, and aggression. Aggression can occur before, after, of in between seizures. Some AEDs are considered to carry a higher risk of aggression, including levetiracetam, perampanel, and topiramate. However, data on the specific risk of aggression for other AEDs is lacking of mixed. It is important for healthcare providers to carefully consider the potential risks and benefits of AEDs when prescribing them for patients with epilepsy of bipolar disorder.

What are the accurate statements about evaluating and handling self-injury in adults?
Your Answer: A psychosocial assessment should not be delayed until after medical treatment is complete
Explanation:It is important to conduct a psychosocial assessment early on in the treatment process, rather than waiting until after medical treatment is complete. During this assessment, it is crucial to speak with the service user alone to ensure confidentiality and allow for open discussion. In cases where physical treatment may trigger traumatic memories, sedation should be offered beforehand. It is also important to assume mental capacity unless evidence suggests otherwise when assessing and treating individuals who have self-harmed. All members of the healthcare team should be able to assess capacity, and challenging cases should involve a team discussion.
Self-Harm and its Management
Self-harm refers to intentional acts of self-poisoning of self-injury. It is prevalent among younger people, with an estimated 10% of girls and 3% of boys aged 15-16 years having self-harmed in the previous year. Risk factors for non-fatal repetition of self-harm include previous self-harm, personality disorder, hopelessness, history of psychiatric treatment, schizophrenia, alcohol abuse/dependence, and drug abuse/dependence. Suicide following an act of self-harm is more likely in those with previous episodes of self-harm, suicidal intent, poor physical health, and male gender.
Risk assessment tools are not recommended for predicting future suicide of repetition of self-harm. The recommended interventions for self-harm include 4-10 sessions of CBT specifically structured for people who self-harm and considering DBT for adolescents with significant emotional dysregulation. Drug treatment as a specific intervention to reduce self-harm should not be offered.
In the management of ingestion, activated charcoal can help if used early, while emetics and cathartics should not be used. Gastric lavage should generally not be used unless recommended by TOXBASE. Paracetamol is involved in 30-40% of acute presentations with poisoning. Intravenous acetylcysteine is the treatment of choice, and pseudo-allergic reactions are relatively common. Naloxone is used as an antidote for opioid overdose, while flumazenil can help reduce the need for admission to intensive care in benzodiazepine overdose.
For superficial uncomplicated skin lacerations of 5 cm of less in length, tissue adhesive of skin closure strips could be used as a first-line treatment option. All children who self-harm should be admitted for an overnight stay at a pediatric ward.

What is a true statement about the HCR-20?
Your Answer: It can be completed individually of by a team
Explanation:One of the primary criticisms of the HCR-20 is its failure to account for protective factors. While formal training is not required to use the tool, it is recommended. Additionally, the HCR-20 only assesses the risk of violence towards people and does not consider violence towards animals of property. The value of the HCR-20 lies in the process of completing it, rather than the final score, which is considered meaningless and cannot be used to determine dangerousness. The HCR-20 can be completed by an individual of a team.
The HCR-20 is a comprehensive tool used to assess the risk of violence in adults. It takes into account various factors from the past, present, and future to provide a holistic view of the individual’s risk. The tool consists of 20 items, which are divided into three domains: historical, clinical, and risk management.
The historical domain includes factors such as previous violence, young age at first violent incident, relationship instability, employment problems, substance use problems, major mental illness, psychopathy, early maladjustment, personality disorder, and prior supervision failure. These factors are important to consider as they provide insight into the individual’s past behavior and potential risk for future violence.
The clinical domain includes factors such as lack of insight, negative attitudes, active symptoms of major mental illness, impulsivity, and unresponsiveness to treatment. These factors are important to consider as they provide insight into the individual’s current mental state and potential risk for future violence.
The risk management domain includes factors such as plans lack feasibility, exposure to destabilizers, lack of personal support, noncompliance with remediation attempts, and stress. These factors are important to consider as they provide insight into the individual’s ability to manage their risk and potential for future violence.
Overall, the HCR-20 is a valuable tool for assessing the risk of violence in adults. It provides a comprehensive view of the individual’s risk and can be used to inform treatment and risk management strategies.

What report aimed to address the disproportionate number of individuals with mental health issues in English prisons?
Your Answer: Butler report
Correct Answer: Bradley report
Explanation:The Bradley Report and its Recommendations for Mental Health in the Criminal Justice System
The Bradley Report was an independent review that aimed to improve the experience of individuals with mental health problems and learning disabilities in the criminal justice system. The report made 82 recommendations for change, including proposals to address the over-representation of people with mental health issues in prisons in England.
One of the key recommendations was the establishment of a national network of Criminal Justice Mental Health teams. These teams would work to divert individuals towards support services from police stations, courts, and after their release from prison. Additionally, the report called for a maximum wait time of 14 days for individuals who require urgent mental health treatment and need to be transferred from prison to hospital. The NHS was also urged to take on the responsibility of providing health services in police stations.
Overall, the Bradley Report highlighted the need for significant changes to be made in the criminal justice system to better support individuals with mental health problems and learning disabilities. Its recommendations have the potential to improve the lives of many vulnerable individuals and reduce the number of people with mental health issues in prisons.

What symptom of characteristic would strongly indicate the presence of Niemann-Pick disease as an underlying diagnosis?
Your Answer: Personality change and attentional issues in adulthood associated with irritability and aggression and jaundice
Correct Answer: Treatment resistant psychosis with executive dysfunction
Explanation:If a patient presents with both treatment resistant psychosis and executive dysfunction, it may be worth considering Niemann-Pick disease. Additionally, if a patient experiences treatment resistant anxiety symptoms accompanied by tachycardia, a pheochromocytoma should be considered. In cases where a patient exhibits personality changes and attentional issues in adulthood, along with irritability, aggression, and jaundice, it may suggest a mixed presentation of Wilson’s disease.
Niemann-Pick disease is a group of inherited diseases where lipids accumulate in the cells of the liver, spleen, and brain. Niemann-Pick Type C (NPC) is the most relevant type for psychiatric presentations, with about one-third of cases presenting in adolescence of adulthood. Symptoms include progressive ataxia/dystonia, cognitive decline, and atypical psychotic symptoms. There are four other types of Niemann-Pick disease, each with their own causes and symptoms. Type A and B have a lack of sphingomyelinase and present in early childhood of mid-childhood/adolescence, respectively. Type C has reduced sphingomyelinase activity and can present at any age, with symptoms including enlarged liver and spleen, learning difficulties, seizures, and slurred speech. Type D is a variant of Type C and has similar symptoms. Type E has reduced sphingomyelinase activity and presents in adulthood with similar symptoms to the other types.

What item is considered high risk according to the MARSIPAN group?
Your Answer: QTc > 450 ms
Explanation:Anorexia is a serious mental health condition that can have severe physical complications. These complications can affect various systems in the body, including the cardiac, skeletal, hematologic, reproductive, metabolic, gastrointestinal, CNS, and dermatological systems. Some of the recognized physical complications of anorexia nervosa include bradycardia, hypotension, osteoporosis, anemia, amenorrhea, hypothyroidism, delayed gastric emptying, cerebral atrophy, and lanugo.
The Royal College of Psychiatrists has issued advice on managing sick patients with anorexia nervosa, recommending hospital admission for those with high-risk items. These items include a BMI of less than 13, a pulse rate of less than 40 bpm, a SUSS test score of less than 2, a sodium level of less than 130 mmol/L, a potassium level of less than 3 mmol/L, a serum glucose level of less than 3 mmol/L, and a QTc interval of more than 450 ms. The SUSS test involves assessing the patient’s ability to sit up and squat without using their hands. A rating of 0 indicates complete inability to rise, while a rating of 3 indicates the ability to rise without difficulty. Proper management and treatment of anorexia nervosa are crucial to prevent of manage these physical complications.

What is the most precise estimation of the occurrence of mental health disorders among adults who have learning disabilities?
Your Answer: 40%
Explanation:Learning Disability and comorbid Psychiatric Illness
It is estimated that 30-50% of adults with learning disabilities also experience mental health problems, including problem behavior. Specific prevalence rates for various mental health disorders in this population have been identified through research. For example, psychotic disorders are present in 4% of adults with learning disabilities, while affective disorders are present in 6%. Autism is the most prevalent disorder, affecting 7.5% of this population.
It is important to note that major depressive disorder can occur at all IQ levels in people with learning disabilities, but may be missed of misinterpreted as challenging behavior. Additionally, individuals with learning disabilities are more susceptible to the negative effects of life events and may develop adjustment disorder. Post-traumatic stress disorder is also common in this population.
Stimulant drugs may be less effective in children with learning disabilities and should be used with caution in individuals with Tourette’s of autism, as they may trigger tics. Overall, it is crucial to recognize and address comorbid psychiatric illness in individuals with learning disabilities to ensure appropriate treatment and support.

What is the recommended course of action for a child with autism who has sleep issues and has not shown improvement with non-pharmacological interventions?
Your Answer: Melatonin
Explanation:According to Maudsley (2012), melatonin is the preferred medication for childhood insomnia. Administering melatonin approximately 30 minutes before bedtime can be helpful in inducing sleep. However, it may not be as effective for early waking issues (Allington-Smith, 2006), although a gradual-release form of melatonin may work for certain cases.
Autism Spectrum Disorder (ASD) is a lifelong disorder characterized by deficits in communication and social understanding, as well as restrictive and repetitive behaviors. The distinction between autism and Asperger’s has been abandoned, and they are now grouped together under the ASD category. Intellectual ability is difficult to assess in people with ASD, with an estimated 33% having an intellectual disability. ASD was first described in Europe and the United States using different terms, with Leo Kanner and Hans Asperger being the pioneers. Diagnosis is based on persistent deficits in social communication and social interaction, as well as restricted, repetitive patterns of behavior. The worldwide population prevalence is about 1%, with comorbidity being common. Heritability is estimated at around 90%, and both genetic and environmental factors seem to cause ASD. Currently, there are no validated pharmacological treatments that alleviate core ASD symptoms, but second-generation antipsychotics are the first-line pharmacological treatment for children and adolescents with ASD and associated irritability.

What is the most frequently observed symptom of Wernicke's encephalopathy upon presentation?
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.

What therapy is founded on Otto Kernberg's idea of 'borderline personality organization'?
Your Answer: Transference focused psychotherapy
Explanation:Personality Disorder (Borderline)
History and Terminology
The term borderline personality disorder originated from early 20th-century theories that the disorder was on the border between neurosis and psychosis. The term borderline was coined by Adolph Stern in 1938. Subsequent attempts to define the condition include Otto Kernberg’s borderline personality organization, which identified key elements such as ego weakness, primitive defense mechanisms, identity diffusion, and unstable reality testing.
Features
The DSM-5 and ICD-11 both define borderline personality disorder as a pervasive pattern of instability in interpersonal relationships, self-image, and affects, and marked impulsivity. Symptoms include efforts to avoid abandonment, unstable relationships, impulsivity, suicidal behavior, affective instability, chronic feelings of emptiness, difficulty controlling temper, and transient dissociative symptoms.
Abuse
Childhood abuse and neglect are extremely common among borderline patients, with up to 87% having suffered some form of trauma. The effect of abuse seems to depend on the stage of psychological development at which it takes place.
comorbidity
Borderline PD patients are more likely to receive a diagnosis of major depressive disorder, bipolar disorder, panic disorder, PTSD, OCD, eating disorders, and somatoform disorders.
Psychological Therapy
Dialectical Behavioral Therapy (DBT), Mentalization-Based Treatment (MBT), Schema-Focused Therapy (SFT), and Transference-Focused Psychotherapy (TFP) are the main psychological treatments for BPD. DBT is the most well-known and widely available, while MBT focuses on improving mentalization, SFT generates structural changes to a patient’s personality, and TFP examines dysfunctional interpersonal dynamics that emerge in interactions with the therapist in the transference.
NICE Guidelines
The NICE guidelines on BPD offer very little recommendations. They do not recommend medication for treatment of the core symptoms. Regarding psychological therapies, they make reference to DBT and MBT being effective but add that the evidence base is too small to draw firm conclusions. They do specifically say Do not use brief psychotherapeutic interventions (of less than 3 months’ duration) specifically for borderline personality disorder of for the individual symptoms of the disorder.

A 35-year-old man repeatedly visits his GP due to distress over his physical appearance. He believes that his ears are too large and this causes him to constantly check his appearance in the mirror and consider ear surgery. Upon examination, there is no obvious physical abnormality of his ears. You determine that his beliefs are overvalued ideas rather than delusional and there is no evidence of depression.
What would be your recommended approach for managing his concerns?Your Answer: Fluvoxamine + CBT
Explanation:Referral for surgical correction of the deformity is not advisable as it may not address the underlying issue of non-delusional body dysmorphic disorder and the patient may shift their focus to another body part. Instead, treatment options such as SSRIs, clomipramine, and CBT should be considered. Antipsychotics may be more appropriate for delusional BDD.

For a study comparing two chemotherapy regimens for small cell lung cancer patients based on survival time, which statistical measure is most suitable for comparison?
Your Answer: Hazard ratio
Explanation:Understanding Hazard Ratio in Survival Analysis
Survival analysis is a statistical method used to analyze the time it takes for an event of interest to occur, such as death of disease progression. In this type of analysis, the hazard ratio (HR) is a commonly used measure that is similar to the relative risk but takes into account the fact that the risk of an event may change over time.
The hazard ratio is particularly useful in situations where the risk of an event is not constant over time, such as in medical research where patients may have different survival times of disease progression rates. It is a measure of the relative risk of an event occurring in one group compared to another, taking into account the time it takes for the event to occur.
For example, in a study comparing the survival rates of two groups of cancer patients, the hazard ratio would be used to compare the risk of death in one group compared to the other, taking into account the time it takes for the patients to die. A hazard ratio of 1 indicates that there is no difference in the risk of death between the two groups, while a hazard ratio greater than 1 indicates that one group has a higher risk of death than the other.
Overall, the hazard ratio is a useful tool in survival analysis that allows researchers to compare the risk of an event occurring between different groups, taking into account the time it takes for the event to occur.

What is a correct statement about funnel plots?
Your Answer: An asymmetric funnel shape confirms the presence of publication bias
Correct Answer: Each dot represents a separate study result
Explanation:An asymmetric funnel plot may indicate the presence of publication bias, although this is not a definitive confirmation. The x-axis typically represents a measure of effect, such as the risk ratio of odds ratio, although other measures may also be used.
Stats Publication Bias
Publication bias refers to the tendency for studies with positive findings to be published more than studies with negative findings, leading to incomplete data sets in meta-analyses and erroneous conclusions. Graphical methods such as funnel plots, Galbraith plots, ordered forest plots, and normal quantile plots can be used to detect publication bias. Funnel plots are the most commonly used and offer an easy visual way to ensure that published literature is evenly weighted. The x-axis represents the effect size, and the y-axis represents the study size. A symmetrical, inverted funnel shape indicates that publication bias is unlikely, while an asymmetrical funnel indicates a relationship between treatment effect and study size, indicating either publication bias of small study effects.

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 statement accurately describes tardive dyskinesia?
Your Answer: Only the muscles of the face are affected
Correct Answer:
Explanation:Tardive Dyskinesia: Symptoms, Causes, Risk Factors, and Management
Tardive dyskinesia (TD) is a condition that affects the face, limbs, and trunk of individuals who have been on neuroleptics for months to years. The movements fluctuate over time, increase with emotional arousal, decrease with relaxation, and disappear with sleep. The cause of TD remains theoretical, but the postsynaptic dopamine (D2) receptor supersensitivity hypothesis is the most persistent. Other hypotheses include the presynaptic dopaminergic/noradrenergic hyperactivity hypothesis, the cholinergic interneuron burnout hypothesis, the excitatory/oxidative stress hypothesis, and the synaptic plasticity hypothesis. Risk factors for TD include advancing age, female sex, ethnicity, longer illness duration, intellectual disability and brain damage, negative symptoms in schizophrenia, mood disorders, diabetes, smoking, alcohol and substance misuse, FGA vs SGA treatment, higher antipsychotic dose, anticholinergic co-treatment, and akathisia.
Management options for TD include stopping any anticholinergic, reducing antipsychotic dose, changing to an antipsychotic with lower propensity for TD, and using tetrabenazine, vitamin E, of amantadine as add-on options. Clozapine is the antipsychotic most likely to be associated with resolution of symptoms. Vesicular monoamine transporter type 2 (VMAT2) inhibitors are agents that cause a depletion of neuroactive peptides such as dopamine in nerve terminals and are used to treat chorea due to neurodegenerative diseases of dyskinesias due to neuroleptic medications (tardive dyskinesia).

What statement is the most accurate regarding school refusal?
Your Answer: Associated with underachievement in educational level
Correct Answer: Associated with moving to a new school.
Explanation:School refusal typically occurs when children are transitioning between schools, particularly from primary to secondary school, which usually happens between the ages of 10 and 13. It affects both boys and girls equally. The primary cause of school refusal is social anxiety, which arises from having to navigate new situations such as making friends on the playground and adapting to new teachers. It is important to note that school refusal is not related to a child’s academic performance.
Understanding School Refusal
School refusal is a common problem that affects 1-5% of children, with similar rates in both boys and girls. Although it can occur at any age, it is more common in children aged five, six, 10, and 11 years. Unlike truancy, school refusal is not a formal diagnosis and is characterized by severe distress about attending school, often manifesting as temper tantrums and somatic symptoms. Parents are generally aware of the absence, and there is no antisocial behavior present. Children with school refusal often have a desire and willingness to do school work at home, whereas those who are truant show little interest in school work in any setting.
The onset of school refusal symptoms is usually gradual and may occur after a holiday of illness. Stressful events at home of school, of with peers, may also cause school refusal. Presenting symptoms include fearfulness, panic symptoms, crying episodes, temper tantrums, threats of self-harm, and somatic symptoms that present in the morning and improve if the child is allowed to stay home.
Behavioural approaches, primarily exposure-based treatments, are used to treat school refusal. However, it is important to note that school refusal is not a diagnosis but a presenting problem that may be linked to other diagnoses such as separation anxiety disorder, generalized anxiety disorder, depression, oppositional defiant disorder, learning disorders, and pervasive developmental disabilities such as Asperger’s disorder, autism, and mental retardation.

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.

What is another name for a DaTscan?
Your Answer: FP-CIT SPECT
Explanation:The purpose of a DaTscan is to aid in the identification of dementia with Lewy bodies in individuals who are suspected to have it.
Dementia is a condition that can be diagnosed and supported with the use of neuroimaging techniques. In Alzheimer’s disease, MRI and CT scans are used to assess volume changes in specific areas of the brain, such as the mesial temporal lobe and temporoparietal cortex. SPECT and PET scans can also show functional changes, such as hypoperfusion and glucose hypometabolism. Vascular dementia can be detected with CT and MRI scans that show atrophy, infarcts, and white matter lesions, while SPECT scans reveal a patchy multifocal pattern of hypoperfusion. Lewy body dementia tends to show nonspecific and subtle changes on structural imaging, but SPECT and PET scans can reveal posterior deficits and reduced D2 receptor density. Frontotemporal dementia is characterized by frontal lobe atrophy, which can be seen on CT and MRI scans, while SPECT scans show anterior perfusion deficits. NICE recommends the use of MRI for early diagnosis and detection of subcortical vascular changes, SPECT for differentiating between Alzheimer’s disease, vascular dementia, and frontotemporal dementia, and DaTscan for establishing a diagnosis of dementia with Lewy bodies.

What is a true statement about diagnosing attention deficit hyperactivity disorder?
Your Answer: Both the ICD-11 and the DSM-5 recognise the combined, predominantly inattentive, and predominantly hyperactive-impulsive subtypes
Explanation:Both the ICD-11 and DSM-5 acknowledge the subtypes of ADHD that are predominantly inattentive, predominantly hyperactive-impulsive, and combined. To make a diagnosis, both require evidence of symptoms before the age of 12 and for at least six months. While DSM-5 specifies six of more symptoms from each category, ICD-11 only requires ‘several’ symptoms without specifying a number. If the hyperactive-impulsive subtype is present, symptoms of inattention are not necessary for a diagnosis. Instead, the diagnosis would be ‘Attention Deficit Hyperactivity Disorder, predominantly hyperactive-impulsive presentation’, as long as there is a persistent pattern of inattention symptoms and/of a combination of hyperactivity and impulsivity symptoms for at least six months.
ADHD (Diagnosis and Management in Children)
ADHD is a behavioural syndrome characterised by symptoms of inattention, hyperactivity, and impulsivity. The DSM-5 and ICD-11 provide diagnostic criteria for the condition, with both recognising three subtypes: predominantly inattentive, predominantly hyperactive-impulsive, and combined.
Treatment for children under 5 involves offering an ADHD-focused group parent-training programme as a first-line option. Medication should only be considered after obtaining advice from a specialist ADHD service. For children and young people aged 5-18, advice and support should be given, along with an ADHD-focused group parent-training programme. Medication should only be offered if ADHD symptoms persist after environmental modifications have been implemented and reviewed. Cognitive behavioural therapy may also be considered for those who have benefited from medication but still experience significant impairment.
NICE advises against elimination diets, dietary fatty acid supplementation, and the use of the ‘few foods diet’. Methylphenidate of lisdexamfetamine is the first-line medication option, with dexamphetamine considered for those who respond to lisdexamfetamine but cannot tolerate the longer effect profile. Atomoxetine of guanfacine may be offered for those who cannot tolerate methylphenidate of lisdexamfetamine. Clonidine and atypical antipsychotics should only be used with advice from a tertiary ADHD service.
Drug holidays may be considered for children and young people who have not met the expected height for their age due to medication. However, NICE advises that withdrawal from treatment is associated with a risk of symptom exacerbation.

Which of the following would be the most appropriate first-line treatment for a 16 year old boy with mild depression?
Your Answer: Systemic family therapy
Correct Answer: Group cognitive behavioural therapy
Explanation:Depression in Young People: NICE Guidelines
The NICE Guidelines for depression in young people are limited to those between the ages of 5-18. For mild depression without significant comorbid problems of active suicidal ideas of plans, watchful waiting is recommended, along with digital CBT, group CBT, group IPT, of group non-directive supportive therapy. For moderate to severe depression, family-based IPT, family therapy, psychodynamic psychotherapy, individual CBT, and fluoxetine may be used for 5-11 year olds, while individual CBT and fluoxetine may be used for 12-18 year olds. Antidepressant medication should not be used for initial treatment of mild depression, and should only be used in combination with concurrent psychological therapy for moderate to severe depression. Fluoxetine is the only antidepressant for which clinical trial evidence shows that the benefits outweigh the risks, and should be used as the first-line treatment. Paroxetine, venlafaxine, tricyclic antidepressants, and St John’s wort should not be used for the treatment of depression in children and young people. Second generation antipsychotics may be used for depression with psychotic symptoms, and ECT should only be considered for those with very severe depression and life-threatening symptoms.

What is a true statement regarding schizophrenia in women?
Your Answer: Women with schizophrenia show worse premorbid functioning than men
Correct Answer: Schizophrenia in women is associated with fewer structural brain abnormalities than in men
Explanation:Schizophrenia presents differently in men and women. Women tend to have a later onset and respond better to treatment, requiring lower doses of antipsychotics. Men, on the other hand, have an earlier onset, poorer premorbid functioning, and more negative symptoms and cognitive deficits. They also have greater structural brain and neurophysiological abnormalities. Females display more affective symptoms, auditory hallucinations, and persecutory delusions, but have a more favorable short- and middle-term course of illness with less smoking and substance abuse. Families of males are more critical, and expressed emotion has a greater negative impact on them. Certain neurological soft signs may be more prevalent in males. There are no clear sex differences in family history, obstetric complications, and minor physical anomalies.
Schizophrenia Epidemiology
Prevalence:
– In England, the estimated annual prevalence for psychotic disorders (mostly schizophrenia) is around 0.4%.
– Internationally, the estimated annual prevalence for psychotic disorders is around 0.33%.
– The estimated lifetime prevalence for psychotic disorders in England is approximately 0.63% at age 43, consistent with the typically reported 1% prevalence over the life course.
– Internationally, the estimated lifetime prevalence for psychotic disorders is around 0.48%.Incidence:
– In England, the pooled incidence rate for non-affective psychosis (mostly schizophrenia) is estimated to be 15.2 per 100,000 years.
– Internationally, the incidence of schizophrenia is about 0.20/1000/year.Gender:
– The male to female ratio is 1:1.Course and Prognosis:
– Long-term follow-up studies suggest that after 5 years of illness, one quarter of people with schizophrenia recover completely, and for most people, the condition gradually improves over their lifetime.
– Schizophrenia has a worse prognosis with onset in childhood of adolescence than with onset in adult life.
– Younger age of onset predicts a worse outcome.
– Failure to comply with treatment is a strong predictor of relapse.
– Over a 2-year period, one-third of patients with schizophrenia showed a benign course, and two-thirds either relapsed of failed to recover.
– People with schizophrenia have a 2-3 fold increased risk of premature death.Winter Births:
– Winter births are associated with an increased risk of schizophrenia.Urbanicity:
– There is a higher incidence of schizophrenia associated with urbanicity.Migration:
– There is a higher incidence of schizophrenia associated with migration.Class:
– There is a higher prevalence of schizophrenia among lower socioeconomic classes.Learning Disability:
– Prevalence rates for schizophrenia in people with learning disabilities are approximately three times greater than for the general population. -

What is the correct approach to managing generalised anxiety disorder?
Your Answer: Active monitoring is suggested for those with features of self-harm
Correct Answer: Suicidal thinking should be monitored weekly for the first month for all people under 30 prescribed SNRIs
Explanation:For individuals under 30 with GAD who are prescribed SSRIs of SNRIs, it is recommended to monitor their suicidal thoughts on a weekly basis during the first month. Non-facilitated self-help typically includes limited therapist interaction, such as brief phone calls lasting no more than 5 minutes.
Anxiety (NICE guidelines)
The NICE Guidelines on Generalised anxiety disorder and panic disorder were issued in 2011. For the management of generalised anxiety disorder, NICE suggests a stepped approach. For mild GAD, education and active monitoring are recommended. If there is no response to step 1, low-intensity psychological interventions such as CBT-based self-help of psychoeducational groups are suggested. For those with marked functional impairment of those who have not responded to step 2, individual high-intensity psychological intervention of drug treatment is recommended. Specialist treatment is suggested for those with very marked functional impairment, no response to step 3, self-neglect, risks of self-harm or suicide, of significant comorbidity. Benzodiazepines should not be used beyond 2-4 weeks, and SSRIs are first line. For panic disorder, psychological therapy (CBT), medication, and self-help have all been shown to be effective. Benzodiazepines, sedating antihistamines, of antipsychotics should not be used. SSRIs are first line, and if they fail, imipramine of clomipramine can be used. Self-help (CBT based) should be encouraged. If the patient improves with an antidepressant, it should be continued for at least 6 months after the optimal dose is reached, after which the dose can be tapered. If there is no improvement after a 12-week course, an alternative medication of another form of therapy should be offered.

What is the estimated percentage of individuals in Great Britain who have a personality disorder?
Your Answer: 11.10%
Correct Answer: 4.40%
Explanation:Personality Disorder: Understanding the Clinical Diagnosis
A personality disorder is a long-standing pattern of behavior and inner experience that deviates significantly from cultural expectations, is inflexible and pervasive, and causes distress of impairment. The DSM-5 and ICD-11 have different approaches to classifying personality disorders. DSM-5 divides them into 10 categories, while ICD-11 has a general category with six trait domains that can be added. To diagnose a personality disorder, clinicians must first establish that the general diagnostic threshold is met before identifying the subtype(s) present. The course of personality disorders varies, with some becoming less evident of remitting with age, while others persist.
DSM-5 and ICD-11 have different classification systems for personality disorders. DSM-5 divides them into three clusters (A, B, and C), while ICD-11 has a general category with six trait domains that can be added. The prevalence of personality disorders in Great Britain is 4.4%, with Cluster C being the most common. Clinicians are advised to avoid diagnosing personality disorders in children, although a diagnosis can be made in someone under 18 if the features have been present for at least a year (except for antisocial personality disorder).
Overall, understanding the clinical diagnosis of personality disorders is important for effective treatment and management of these conditions.

What is a true statement about supportive psychotherapy?
Your Answer: Is only indicated in well-adjusted clients
Correct Answer: Defense mechanisms should be stabilized rather than challenged
Explanation:Supportive Psychotherapy: An Overview
Supportive psychotherapy is a widely used approach in psychiatry, often reserved for clients who are not suitable for other forms of therapy. It aims to provide emotional support and encouragement to help people cope with overwhelming stress and restore them to their previous level of functioning. This therapy is not based on any specific psychological theory and is eclectic in approach.
Supportive psychotherapy is generally used with two different patient groups: those who were otherwise functioning well but have become symptomatic due to stress, and those who are not suitable for other forms of therapy. The goal of therapy is to help the patient get on with their life as best as possible, without disrupting reasonable defenses of generating conflicts.
The therapist avoids confrontation and transference issues are rarely analyzed. However, the therapeutic aims of long-term supportive psychotherapy include establishing a therapeutic alliance, holding and containing, promoting awareness of transference issues, promoting stability, facilitating the maturation of defenses, and promoting better adaptation to reality.
Supportive psychotherapy has been dismissed as ‘hand holding,’ but it should not be underestimated. It is suitable for most patients and is often the only therapy that can help when others have failed. Much of the work doctors do in outpatient clinics could be classified as supportive psychotherapy.

What is the duration of time that cannabis can be detected in the urine of individuals who use it frequently, following their last consumption?
Your Answer: 5 days
Correct Answer: 14 days
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.

Explanation:Mothers who require hospitalization for a mental illness within a year of delivering a baby should be admitted to a dedicated facility that specializes in caring for both the mother and her infant.
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.

A 9-year-old boy has been referred by his GP due to problematic behaviour. He has been physically aggressive towards his peers and consistently defiant with his mother. What would be the most appropriate course of action?
Your Answer: Group based parent training
Explanation:According to the NICE guidelines from 2006, the behavior described is indicative of conduct disorder and group-based parental training/educational programs are recommended for managing children with this disorder.
Disruptive Behaviour of Dissocial Disorders
Conduct disorders are the most common reason for referral of young children to mental health services. These disorders are characterized by a repetitive and persistent pattern of antisocial, aggressive, of defiant conduct that goes beyond ordinary childish mischief of adolescent rebelliousness. Oppositional defiant disorder (ODD) shares some negative attributes but in a more limited fashion.
ICD-11 terms the disorder as ‘Conduct-dissocial disorder’, while DSM-5 recognizes three separate conditions related to emotional/behavioral problems seen in younger people: conduct disorder, oppositional defiant disorder, and intermittent explosive disorder. Conduct disorder is about poorly controlled behavior, intermittent explosive disorder is about poorly controlled emotions, and ODD is in between. Conduct disorders are further divided into childhood onset (before 10 years) and adolescent onset (10 years of older).
The behavior pattern of conduct disorders must be persistent and recurrent, including multiple incidents of aggression towards people of animals, destruction of property, deceitfulness of theft, and serious violations of rules. The pattern of behavior must result in significant impairment in personal, family, social, educational, occupational, of other important areas of functioning.
Oppositional defiant disorder represents a less severe form of conduct disorder, where there is an absence of more severe dissocial of aggressive acts. The behavior pattern of ODD includes persistent difficulty getting along with others, provocative, spiteful, of vindictive behavior, and extreme irritability of anger.
The prevalence of conduct disorders increases throughout childhood and is more common in boys than girls. The most frequent comorbid problem seen with conduct disorder is hyperactivity. The conversion rate from childhood conduct disorder to adult antisocial personality disorder varies from 40 to 70% depending on the study.
NICE recommends group parent-based training programs of parent and child training programs for children with complex needs for ages 3-11, child-focused programs for ages 9-14, and multimodal interventions with a family focus for ages 11-17. Medication is not recommended in routine practice, but risperidone can be used where other approaches fail and they are seriously aggressive.

Which variable has a zero value that is not arbitrary?
Your Answer: Ratio
Explanation:The key characteristic that sets ratio variables apart from interval variables is the presence of a meaningful zero point. On a ratio scale, this zero point signifies the absence of the measured attribute, while on an interval scale, the zero point is simply a point on the scale with no inherent significance.
Scales of Measurement in Statistics
In the 1940s, Stanley Smith Stevens introduced four scales of measurement to categorize data variables. Knowing the scale of measurement for a variable is crucial in selecting the appropriate statistical analysis. The four scales of measurement are ratio, interval, ordinal, and nominal.
Ratio scales are similar to interval scales, but they have true zero points. Examples of ratio scales include weight, time, and length. Interval scales measure the difference between two values, and one unit on the scale represents the same magnitude on the trait of characteristic being measured across the whole range of the scale. The Fahrenheit scale for temperature is an example of an interval scale.
Ordinal scales categorize observed values into set categories that can be ordered, but the intervals between each value are uncertain. Examples of ordinal scales include social class, education level, and income level. Nominal scales categorize observed values into set categories that have no particular order of hierarchy. Examples of nominal scales include genotype, blood type, and political party.
Data can also be categorized as quantitative of qualitative. Quantitative variables take on numeric values and can be further classified into discrete and continuous types. Qualitative variables do not take on numerical values and are usually names. Some qualitative variables have an inherent order in their categories and are described as ordinal. Qualitative variables are also called categorical of nominal variables. When a qualitative variable has only two categories, it is called a binary variable.

What tool is utilized to assess for the presence of personality disorder?
Your Answer: IPDE
Explanation:There are several screening tools available for personality disorder, including SAPAS, FFMRF, IPDE, PDQ-R, IPDS, and IIP-PD. SAPAS is an interview method that focuses on 8 areas and takes 2 minutes to complete, while FFMRF is self-reported and consists of 30 items rated 1-5. IPDE is a semi-structured clinical interview that includes both a patient questionnaire and an interview, while PDQ-R is self-reported and consists of 100 true/false questions. IPDS is an interview method that consists of 11 criteria and takes less than 5 minutes, while IIP-PD is self-reported and contains 127 items rated 0-4. A score of 3 of more on SAPAS warrants further assessment.

A 68-year-old man develops a major depressive illness following a stroke. During the discussion of treatment options, he discloses that he had a gastric bleed 4 years ago. What would be the recommended treatment approach in this scenario?
Your Answer: Nortriptyline
Explanation:Considering his past GI bleed, it would be wise to steer clear of prescribing an SSRI as they have been linked to a higher likelihood of future bleeding.
Depression is a common occurrence after a stroke, affecting 30-40% of patients. The location of the stroke lesion can play a crucial role in the development of major depression. Treatment for post-stroke depression must take into account the cause of the stroke, medical comorbidities, and potential interactions with other medications. The Maudsley guidelines recommend SSRIs as the first-line treatment, with paroxetine being the preferred choice. Nortriptyline is also an option, as it does not increase the risk of bleeding. If the patient is on anticoagulants, citalopram and escitalopram may be preferred. Antidepressant prophylaxis has been shown to be effective in preventing post-stroke depression, with nortriptyline, fluoxetine, escitalopram, duloxetine, sertraline, and mirtazapine being effective options. Mianserin, however, appears to be ineffective.

For what purpose is the Gudjonsson Scale primarily used in assessment?
Your Answer: Suggestibility
Explanation:The Gudjonsson Suggestibility Scale
The Gudjonsson Suggestibility Scale is a tool used to measure suggestibility in individuals. It involves reading a story to participants, who are then asked to recall as much as they can remember. Afterward, participants are asked 20 questions related to the story, 15 of which are misleading. Once the questions have been answered, participants are given negative feedback on their performance and told that they made several errors. They are then asked to repeat the questions to obtain more accurate answers. Based on the participants’ responses to the misleading questions, a total suggestibility score can be calculated. This scale is useful in understanding how easily individuals can be influenced of manipulated by external factors.

What factor indicates a poor outcome for individuals with anorexia nervosa?
Your Answer: Low level of intelligence
Correct Answer: Late onset
Explanation:Contrary to traditional beliefs, the latest evidence indicates that being male is actually a positive prognostic indicator in anorexia.
Anorexia Prognosis
The long-term outcomes of anorexia are difficult to determine due to high drop-out rates from follow-up. However, one study found that over a 29 year period, half of patients recovered completely, a third recovered partially, 20% had a chronic eating disorder, and 5% died. Factors associated with a poor prognosis include a long duration of hospital care, psychiatric comorbidity, being adopted, growing up in a one-parent household, and having a young mother. Other factors that have been found to contribute to a poor prognosis include lower minimum weight, poor family relationships, failed treatment, late age of onset, and social problems.

An aging patient with dementia who has shown improvement with donepezil treatment has had their dosage raised. They come back to the clinic reporting issues with urinary incontinence. What course of action would you recommend?
Your Answer: Reduce the dose and suggest continuing
Explanation:Since donepezil has shown a positive response, it would be inappropriate to discontinue it. However, urinary incontinence associated with the medication should not be disregarded as it can limit patients’ activities and quality of life. While it may often be transient and not serious, a lower dose of donepezil of the use of a peripherally acting cholinergic antagonist may be helpful in managing this adverse effect. It is important to recognize urinary incontinence as a potential manifestation of dementia. These recommendations were made by M Hashimoto in a 2000 article in The Lancet.
Treatment of Dementia: AChE Inhibitors and Memantine
Dementia is a debilitating condition that affects millions of people worldwide. Acetylcholinesterase inhibitors (AChE inhibitors) and memantine are two drugs used in the management of dementia. AChE inhibitors prevent cholinesterase from breaking down acetylcholine, which is deficient in Alzheimer’s due to loss of cholinergic neurons. Donepezil, galantamine, and rivastigmine are AChE inhibitors used in the management of Alzheimer’s. Memantine is an NMDA receptor antagonist that blocks the effects of pathologically elevated levels of glutamate that may lead to neuronal dysfunction.
NICE guidelines recommend the use of AChE inhibitors for managing mild to moderate Alzheimer’s and memantine for managing moderate to severe Alzheimer’s. For those already taking an AChE inhibitor, memantine can be added if the disease is moderate of severe. AChE inhibitors are also recommended for managing mild, moderate, and severe dementia with Lewy bodies, while memantine is considered if AChE inhibitors are not tolerated of contraindicated. AChE inhibitors and memantine are not recommended for vascular dementia, frontotemporal dementia, of cognitive impairment due to multiple sclerosis.
The British Association for Psychopharmacology recommends AChE inhibitors as the first choice for Alzheimer’s and mixed dementia, while memantine is the second choice. AChE inhibitors and memantine are also recommended for dementia with Parkinson’s and dementia with Lewy bodies.
In summary, AChE inhibitors and memantine are important drugs used in the management of dementia. The choice of drug depends on the type and severity of dementia, as well as individual patient factors.

What is your suspicion regarding the male remand prisoner's condition based on his inconsistent responses during the interview, despite retaining core details about his identity and awareness of his surroundings?
Your Answer: Ganser's syndrome
Explanation:Ganser’s syndrome is a disputed diagnosis that typically involves vague responses, confusion, physical symptoms without a clear medical explanation, false perceptions, and memory loss for the time when the symptoms were present. It is commonly observed in incarcerated individuals awaiting trial and seems to be a manifestation of their perception of what a psychotic disorder entails. As a result, some experts argue that it is a type of feigning illness. The condition is classified as a dissociative disorder.
Somatoform and dissociative disorders are two groups of psychiatric disorders that are characterized by physical symptoms and disruptions in the normal integration of identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, of behavior. Somatoform disorders are characterized by physical symptoms that are presumed to have a psychiatric origin, while dissociative disorders are characterized by the loss of integration between memories, identity, immediate sensations, and control of bodily movements. The ICD-11 lists two main types of somatoform disorders: bodily distress disorder and body integrity dysphoria. Dissociative disorders include dissociative neurological symptom disorder, dissociative amnesia, trance disorder, possession trance disorder, dissociative identity disorder, partial dissociative identity disorder, depersonalization-derealization disorder, and other specified dissociative disorders. The symptoms of these disorders result in significant impairment in personal, family, social, educational, occupational, of other important areas of functioning. Diagnosis of these disorders involves a thorough evaluation of the individual’s symptoms and medical history, as well as ruling out other possible causes of the symptoms.

What is the likelihood of developing Alzheimer's after the age of 60?
Your Answer: Double every 5 years
Explanation:Alzheimer’s Disease: Understanding the Risk Factors
At the age of 60, the risk of developing Alzheimer’s disease is relatively low, estimated to be around 1%. However, this risk doubles every five years, reaching a significant 30% to 50% by the age of 85. While it was once believed that aluminium exposure was a cause of Alzheimer’s, recent research suggests otherwise. Instead, there appears to be a strong link between serious head injuries and an increased risk of developing Alzheimer’s later in life. Additionally, hypertension and cardiovascular problems have also been identified as risk factors for Alzheimer’s, not just vascular dementia. It is important to understand these risk factors and take steps to reduce them in order to potentially lower the risk of developing Alzheimer’s disease.

For which condition is lithium the most suitable treatment option?
Your Answer: Steroid-induced psychosis
Explanation:The preferred treatment for pseudologia fantastica (pathological lying) is psychotherapy.
Lithium – Clinical Usage
Lithium is primarily used as a prophylactic agent for bipolar disorder, where it reduces the severity and number of relapses. It is also effective as an augmentation agent in unipolar depression and for treating aggressive and self-mutilating behavior, steroid-induced psychosis, and to raise WCC in people using clozapine.
Before prescribing lithium, renal, cardiac, and thyroid function should be checked, along with a Full Blood Count (FBC) and BMI. Women of childbearing age should be advised regarding contraception, and information about toxicity should be provided.
Once daily administration is preferred, and various preparations are available. Abrupt discontinuation of lithium increases the risk of relapse, and if lithium is to be discontinued, the dose should be reduced gradually over a period of at least 4 weeks.
Inadequate monitoring of patients taking lithium is common, and it is often an exam hot topic. Lithium salts have a narrow therapeutic/toxic ratio, and samples should ideally be taken 12 hours after the dose. The target range for prophylaxis is 0.6–0.75 mmol/L.
Risk factors for lithium toxicity include drugs altering renal function, decreased circulating volume, infections, fever, decreased oral intake of water, renal insufficiency, and nephrogenic diabetes insipidus. Features of lithium toxicity include GI and neuro symptoms.
The severity of toxicity can be assessed using the AMDISEN rating scale.

A teenager prescribed clozapine for schizophrenia develops depression and is given an SSRI. Three days after starting the new tablets they have a seizure and are admitted to hospital. What is the most probable cause of the seizure?
Your Answer: Fluoxetine
Explanation:When taken with clozapine, many SSRIs can cause an increase in its levels. However, citalopram and escitalopram are considered safe as they do not affect the cytochrome system. Although paroxetine is believed to interact, it has been proven safe when used at normal clinical doses alongside clozapine. Sertraline has minimal impact on clozapine levels.
Interactions of Antidepressants with Cytochrome P450 System
Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), can have significant effects on the cytochrome P450 system. This can result in drug interactions that can affect the efficacy and safety of the medications.
One example of such interaction is between fluvoxamine and theophylline. Fluvoxamine is a potent inhibitor of CYP1A2, which can lead to increased levels of theophylline in the body. This can cause adverse effects such as nausea, vomiting, and tremors.
Another example is between fluoxetine and clozapine. Fluoxetine is a potent inhibitor of CYP2D6, which can increase the risk of seizures with clozapine. Clozapine is metabolized by CYP1A2, CYP3A4, and CYP2D6, and any inhibition of these enzymes can affect its metabolism and increase the risk of adverse effects.
It is important to be aware of these interactions and monitor patients closely when prescribing antidepressants, especially in those who are taking other medications that are metabolized by the cytochrome P450 system.

A 25-year-old marathon runner who is currently training for a regional race requests to meet with the team physician due to an unusual sensation in her legs. She reports feeling a numbness below her knee. Upon examination, the physician observes sensory loss below the left knee in a non-dermatomal distribution. After conducting further investigations, which all come back normal, the physician concludes that the symptoms are not consistent with neurological disease. During a discussion with the patient's parents, the physician learns that the patient recently lost her sister in a tragic accident. Despite this, the patient appears strangely indifferent to her symptoms. What is the most likely diagnosis at this point?
Your Answer: Dissociative neurological symptom disorder
Explanation:Somatoform and dissociative disorders are two groups of psychiatric disorders that are characterized by physical symptoms and disruptions in the normal integration of identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, of behavior. Somatoform disorders are characterized by physical symptoms that are presumed to have a psychiatric origin, while dissociative disorders are characterized by the loss of integration between memories, identity, immediate sensations, and control of bodily movements. The ICD-11 lists two main types of somatoform disorders: bodily distress disorder and body integrity dysphoria. Dissociative disorders include dissociative neurological symptom disorder, dissociative amnesia, trance disorder, possession trance disorder, dissociative identity disorder, partial dissociative identity disorder, depersonalization-derealization disorder, and other specified dissociative disorders. The symptoms of these disorders result in significant impairment in personal, family, social, educational, occupational, of other important areas of functioning. Diagnosis of these disorders involves a thorough evaluation of the individual’s symptoms and medical history, as well as ruling out other possible causes of the symptoms.

Which of the following skills is not considered a micro-counselling technique utilized in motivational interviewing?
Your Answer: Open ended questions
Correct Answer: Facilitations
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.

According to Klerman's bipolar subtypes, what term is used to describe a state of mania without depression?
Your Answer: Bipolar V
Correct Answer: Bipolar VI
Explanation:Bipolar Disorder: Historical Subtypes
Bipolar disorder is a complex mental illness that has been classified into several subtypes over the years. The most widely recognized subtypes are Bipolar I, Bipolar II, and Cyclothymia. However, there have been other classification systems proposed by experts in the field.
In 1981, Gerald Klerman proposed a classification system that included Bipolar I, Bipolar II, Bipolar III, Bipolar IV, Bipolar V, and Bipolar VI. This system was later expanded by Akiskal in 1999, who added more subtypes such as Bipolar I 1/2, Bipolar II 1/2, and Bipolar III 1/2.
Bipolar I is characterized by full-blown mania, while Bipolar II is characterized by hypomania with depression. Cyclothymia is a milder form of bipolar disorder that involves cycling between hypomania and mild depression.
Other subtypes include Bipolar III, which is associated with hypomania of mania precipitated by antidepressant drugs, and Bipolar IV, which is characterized by hyperthymic depression. Bipolar V is associated with depressed patients who have a family history of bipolar illness, while Bipolar VI is characterized by mania without depression (unipolar mania).
Overall, the classification of bipolar disorder subtypes has evolved over time, and different experts have proposed different systems. However, the most widely recognized subtypes are still Bipolar I, Bipolar II, and Cyclothymia.

For what purpose was the SUSS test created to assess?
Your Answer: Anorexia nervosa
Explanation:The SUSS test was created to aid in the evaluation and assessment of anorexia nervosa by providing a more precise method of measuring power. Traditional neurological examinations of anorexia patients often miss significant power deficiencies caused by muscle loss. The test requires patients to transition from lying down to sitting up, then squatting, and finally standing up again, with a structured scoring system in place.
Anorexia is a serious mental health condition that can have severe physical complications. These complications can affect various systems in the body, including the cardiac, skeletal, hematologic, reproductive, metabolic, gastrointestinal, CNS, and dermatological systems. Some of the recognized physical complications of anorexia nervosa include bradycardia, hypotension, osteoporosis, anemia, amenorrhea, hypothyroidism, delayed gastric emptying, cerebral atrophy, and lanugo.
The Royal College of Psychiatrists has issued advice on managing sick patients with anorexia nervosa, recommending hospital admission for those with high-risk items. These items include a BMI of less than 13, a pulse rate of less than 40 bpm, a SUSS test score of less than 2, a sodium level of less than 130 mmol/L, a potassium level of less than 3 mmol/L, a serum glucose level of less than 3 mmol/L, and a QTc interval of more than 450 ms. The SUSS test involves assessing the patient’s ability to sit up and squat without using their hands. A rating of 0 indicates complete inability to rise, while a rating of 3 indicates the ability to rise without difficulty. Proper management and treatment of anorexia nervosa are crucial to prevent of manage these physical complications.

The patient inquires about the potential memory impairment caused by ECT. Which specific type of memory is impacted by this procedure?
Your Answer: Retrograde only
Correct Answer: Retrograde and anterograde
Explanation:Electroconvulsive therapy (ECT) is known to cause retrograde amnesia, which is the most persistent cognitive side effect (Lisanby, 2000). Patients often experience memory gaps for events that occurred around the time of ECT, and sometimes even for events that happened months of years prior. While retrograde amnesia typically improves within a few months after treatment, some patients may not fully recover and may have permanent memory loss for events close to the time of treatment. Additionally, anterograde amnesia may also be a possible side effect.
ECT (Treatment) – Summary of Effectiveness and Recommendations
ECT (Electroconvulsive Therapy) is a treatment that induces a therapeutic seizure through the application of electrical current under general anesthesia and muscle relaxation. It is prescribed as a course and is usually administered twice weekly for 6 to 12 treatments. ECT is the most effective short-term treatment for major depression, with remission rates of around 60-80% when used as first-line treatment in a severe depressive episode. However, without maintenance treatment, the relapse rate is extremely high (over 80%) in the 6 months after successful ECT.
Cognitive effects are the main limitation to the wider use of ECT, particularly acute confusion shortly after the treatment, retrograde amnesia, and some losses in autobiographical memory longer term. The current state of evidence does not allow the general use of ECT in the management of schizophrenia. Bilateral ECT is more effective than unilateral ECT but may cause more cognitive impairment. With unilateral ECT, a higher stimulus dose is associated with greater efficacy but also increased cognitive impairment compared with a lower stimulus dose.
NICE (National Institute for Health and Care Excellence) recommends that ECT is used only to achieve rapid and short-term improvement of severe symptoms after an adequate trial of other treatment options has proven ineffective and/of when the condition is considered to be potentially life-threatening. ECT is recommended for individuals with severe depression (that is life-threatening and when a rapid response is required, of when other treatments have failed), moderate depression (consider it if their depression has not responded to multiple drug treatments and psychological treatment), catatonia, and a prolonged of severe manic episode.
The RCPsych (Royal College of Psychiatrists) position on ECT recommends it as a first-line treatment for individuals with high suicidal risk, severe psychomotor retardation and associated problems of compromised eating and drinking and/of physical deterioration, treatment-resistant depression that has responded to ECT in a previous episode of illness, pregnant individuals with severe depression, of severe mixed affective states, mania of catatonia and whose physical health of that of the fetus is at serious risk, and those who prefer this form of treatment. ECT is recommended as a second-line treatment for individuals with treatment-resistant depression, severe side-effects from medication, and persistent of life-threatening symptoms in severe of prolonged mania. ECT is indicated in some circumstances for individuals with bipolar depression, postnatal psychosis, treatment-resistant schizophrenia, treatment-resistant catatonia, and frequent relapses and recurrences of depression (maintenance).
