Question 1
Incorrect
-
A 28-year-old man who works as a software engineer has recently been terminated by his supervisor, citing missed deadlines and a decline in the quality of his work. He disputes this and claims that his supervisor has always had a personal vendetta against him. He has confided in his family and close friends, but despite their reassurances, he believes that some of his colleagues were colluding with his supervisor to oust him. During his mental health evaluation, he appears to be generally stable, except for his fixation on his supervisor and coworkers conspiring against him. His family reports that he is easily offended and has a tendency to believe in conspiracies. What is the most probable diagnosis?
Your Answer: Schizotypal personality disorder
Correct Answer: Paranoid personality disorder
Explanation:The diagnosis of paranoid personality disorder may be appropriate for individuals who exhibit hypersensitivity, hold grudges when insulted, doubt the loyalty of those around them, and are hesitant to confide in others.
In the given case, the correct diagnosis is paranoid personality disorder as the individual is reacting strongly to being fired by her manager and believes it to be a conspiracy involving her manager and colleagues. This aligns with the classic symptoms of paranoid personality disorder, and the individual’s family has also observed her tendency to be easily offended and paranoid.
Borderline personality disorder is an incorrect diagnosis as it is characterized by emotional instability, difficulty controlling anger, unstable relationships, and recurrent suicidal thoughts, rather than paranoia.
Schizoid personality disorder is also an incorrect diagnosis as it is characterized by a preference for solitary activities, lack of interest in socializing, and a lack of close relationships, rather than paranoia.
Schizophrenia is an incorrect diagnosis as the individual’s mental state examination is broadly normal, whereas schizophrenia typically presents with delusions, hallucinations, and disordered thinking.
Personality disorders are a set of personality traits that are maladaptive and interfere with normal functioning in life. It is estimated that around 1 in 20 people have a personality disorder, which are typically categorized into three clusters: Cluster A, which includes Odd or Eccentric disorders such as Paranoid, Schizoid, and Schizotypal; Cluster B, which includes Dramatic, Emotional, or Erratic disorders such as Antisocial, Borderline (Emotionally Unstable), Histrionic, and Narcissistic; and Cluster C, which includes Anxious and Fearful disorders such as Obsessive-Compulsive, Avoidant, and Dependent.
Paranoid individuals exhibit hypersensitivity and an unforgiving attitude when insulted, a reluctance to confide in others, and a preoccupation with conspiratorial beliefs and hidden meanings. Schizoid individuals show indifference to praise and criticism, a preference for solitary activities, and emotional coldness. Schizotypal individuals exhibit odd beliefs and magical thinking, unusual perceptual disturbances, and inappropriate affect. Antisocial individuals fail to conform to social norms, deceive others, and exhibit impulsiveness, irritability, and aggressiveness. Borderline individuals exhibit unstable interpersonal relationships, impulsivity, and affective instability. Histrionic individuals exhibit inappropriate sexual seductiveness, a need to be the center of attention, and self-dramatization. Narcissistic individuals exhibit a grandiose sense of self-importance, lack of empathy, and excessive need for admiration. Obsessive-compulsive individuals are occupied with details, rules, and organization to the point of hampering completion of tasks. Avoidant individuals avoid interpersonal contact due to fears of criticism or rejection, while dependent individuals have difficulty making decisions without excessive reassurance from others.
Personality disorders are difficult to treat, but a number of approaches have been shown to help patients, including psychological therapies such as dialectical behavior therapy and treatment of any coexisting psychiatric conditions.

Question 2
Incorrect
-
A 27-year-old woman has been experiencing a pattern of tumultuous endings in all of her relationships. She confides in you that she seems to have a knack for choosing friends and romantic partners who ultimately reveal themselves to be awful people.
What defense mechanism is most likely at play in this patient?Your Answer: Sublimation
Correct Answer: Splitting
Explanation:Defense Mechanisms: Understanding How We Cope
Defense mechanisms are psychological strategies that we use to protect ourselves from anxiety and emotional pain. These mechanisms are often unconscious and can be both adaptive and maladaptive. Here are some common defense mechanisms and their explanations:
Splitting: This is a common defense mechanism in borderline personality disorder. It involves seeing people as either all good or all bad, and the inability to reconcile both good and bad traits in a person.
Dissociation: This is an immature defense mechanism where one’s personal identity is temporarily modified to avoid distress. An extreme form is dissociative identity disorder.
Identification: This is when someone models the behavior of a more powerful example. An example would be a victim of child abuse becoming a child abuser in adulthood.
Sublimation: This is a mature defense mechanism where the person takes an unacceptable personality trait and uses it to drive a respectable work that does not conflict with their value system.
Reaction formation: This is an immature defense mechanism where unacceptable emotions are repressed and replaced by their exact opposite. A classic example is a man with homoerotic desires championing anti-homosexual public policy.
Understanding these defense mechanisms can help us recognize when we are using them and how they may be impacting our relationships and mental health.

A 56-year-old man without medical history is beginning treatment with tranylcypromine for his depression. What foods should he be cautioned against consuming?
Your Answer: Cheese
Explanation:To prevent a hypertensive crisis, individuals taking monoamine oxidase inhibitors (MAOIs) should steer clear of tyramine-containing foods, such as cheese. Other foods have not been found to have an interaction with MAOIs.
Monoamine Oxidase Inhibitors and their Adverse Effects
Monoamine oxidase inhibitors are drugs that inhibit the enzyme monoamine oxidase, which is responsible for the breakdown of neurotransmitters such as serotonin and noradrenaline in the presynaptic cell. Non-selective monoamine oxidase inhibitors, such as tranylcypromine and phenelzine, are used in the treatment of atypical depression and other psychiatric disorders. However, they are not commonly used due to their adverse effects.
One of the main adverse effects of non-selective monoamine oxidase inhibitors is hypertensive reactions when consuming tyramine-containing foods such as cheese, pickled herring, Bovril, Oxo, Marmite, and broad beans. This is because monoamine oxidase normally breaks down tyramine, but when inhibited by the drug, tyramine can accumulate and cause a sudden increase in blood pressure. Therefore, patients taking non-selective monoamine oxidase inhibitors must adhere to a strict diet that avoids these foods.
Another adverse effect of non-selective monoamine oxidase inhibitors is anticholinergic effects, which can cause dry mouth, blurred vision, constipation, and urinary retention. These effects are due to the inhibition of the enzyme acetylcholinesterase, which breaks down the neurotransmitter acetylcholine. As a result, acetylcholine levels increase and can lead to these side effects.
In conclusion, while non-selective monoamine oxidase inhibitors can be effective in treating certain psychiatric disorders, they are not commonly used due to their adverse effects. Patients taking these drugs must adhere to a strict diet and be monitored for potential side effects.

Question 4
Correct

A 28-year-old woman contacts her doctor seeking guidance on stopping all of her medications abruptly. She has a medical history of asthma, depression, and occasional tennis elbow pain, for which she takes a salbutamol inhaler, citalopram, and paracetamol, respectively. What is the most probable outcome if she discontinues her medications suddenly?
Your Answer: Diarrhoea
Explanation:When it comes to discontinuing medication, it’s important to note the specific drug being used. Abruptly stopping a salbutamol inhaler or paracetamol is unlikely to cause any adverse effects. However, stopping a selective serotonin reuptake inhibitor (SSRI) like citalopram can lead to discontinuation symptoms. Gastrointestinal side-effects, such as diarrhoea, are commonly seen in SSRI discontinuation syndrome. To avoid this, it’s recommended to gradually taper off SSRIs. Blunted affect is not likely to occur as a result of sudden discontinuation, but emotional lability and mood swings may be observed. Cyanopsia, or blue-tinted vision, is not a known symptom of SSRI discontinuation, but it can be a side effect of other drugs like sildenafil. While hypertension has been reported in some cases, it’s less common than gastrointestinal symptoms. Weight loss, rather than weight gain, is often reported upon sudden discontinuation of SSRIs.
Selective serotonin reuptake inhibitors (SSRIs) are commonly used as the first-line treatment for depression. Citalopram and fluoxetine are the preferred SSRIs, while sertraline is recommended for patients who have had a myocardial infarction. However, caution should be exercised when prescribing SSRIs to children and adolescents. Gastrointestinal symptoms are the most common side-effect, and patients taking SSRIs are at an increased risk of gastrointestinal bleeding. Patients should also be aware of the possibility of increased anxiety and agitation after starting a SSRI. Fluoxetine and paroxetine have a higher propensity for drug interactions.
The Medicines and Healthcare products Regulatory Agency (MHRA) has issued a warning regarding the use of citalopram due to its association with dose-dependent QT interval prolongation. As a result, citalopram and escitalopram should not be used in patients with congenital long QT syndrome, known pre-existing QT interval prolongation, or in combination with other medicines that prolong the QT interval. The maximum daily dose of citalopram is now 40 mg for adults, 20 mg for patients older than 65 years, and 20 mg for those with hepatic impairment.
When initiating antidepressant therapy, patients should be reviewed by a doctor after 2 weeks. Patients under the age of 25 years or at an increased risk of suicide should be reviewed after 1 week. If a patient responds well to antidepressant therapy, they should continue treatment for at least 6 months after remission to reduce the risk of relapse. When stopping a SSRI, the dose should be gradually reduced over a 4 week period, except for fluoxetine. Paroxetine has a higher incidence of discontinuation symptoms, including mood changes, restlessness, difficulty sleeping, unsteadiness, sweating, gastrointestinal symptoms, and paraesthesia.
When considering the use of SSRIs during pregnancy, the benefits and risks should be weighed. Use during the first trimester may increase the risk of congenital heart defects, while use during the third trimester can result in persistent pulmonary hypertension of the newborn. Paroxetine has an increased risk of congenital malformations, particularly in the first trimester.

Question 5
Correct

You are working in a GP surgery and your next patient is John, a 35-year-old man with a diagnosis of generalised anxiety disorder (GAD). He is currently prescribed sertraline 200mg daily.
During the review of his symptoms today, John reports that he does not feel like the sertraline is helping, and he remains anxious almost all of the time. He experiences frequent episodes where he feels his heart pounding in his chest and his head is spinning. Additionally, he notes that he often struggles to get to sleep and can lie awake for hours at night.
As you observe John, he appears visibly distressed. He seems unable to sit still in his chair and is trembling slightly.
What would be the next step in John's management?Your Answer: Change the prescription to duloxetine
Explanation:If sertraline is not effective or not well-tolerated in the treatment of generalised anxiety disorder (GAD), an alternative SSRI or SNRI should be prescribed. In this case, duloxetine is the recommended option as it is an SNRI. Mirtazapine, although it has been shown to have an effect on anxiety symptoms, is not part of the NICE guidance for GAD treatment. Pregabalin may be considered if the patient cannot tolerate SSRI or SNRI treatment, but this is not yet necessary for Susan. Increasing the dose of sertraline is not an option as she is already on the maximum dose. Benzodiazepines should not be offered for the treatment of GAD except as a short-term measure during a crisis, according to NICE guidelines.
Anxiety is a common disorder that can manifest in various ways. According to NICE, the primary feature is excessive worry about multiple events associated with heightened tension. It is crucial to consider potential physical causes when diagnosing anxiety disorders, such as hyperthyroidism, cardiac disease, and medication-induced anxiety. Medications that may trigger anxiety include salbutamol, theophylline, corticosteroids, antidepressants, and caffeine.
NICE recommends a step-wise approach for managing generalised anxiety disorder (GAD). This includes education about GAD and active monitoring, low-intensity psychological interventions, high-intensity psychological interventions or drug treatment, and highly specialist input. Sertraline is the first-line SSRI for drug treatment, and if it is ineffective, an alternative SSRI or a serotonin-noradrenaline reuptake inhibitor (SNRI) such as duloxetine or venlafaxine may be offered. If the patient cannot tolerate SSRIs or SNRIs, pregabalin may be considered. For patients under 30 years old, NICE recommends warning them of the increased risk of suicidal thinking and self-harm and weekly follow-up for the first month.
The management of panic disorder also follows a stepwise approach, including recognition and diagnosis, treatment in primary care, review and consideration of alternative treatments, review and referral to specialist mental health services, and care in specialist mental health services. NICE recommends either cognitive behavioural therapy or drug treatment in primary care. SSRIs are the first-line drug treatment, and if contraindicated or no response after 12 weeks, imipramine or clomipramine should be offered.

You are asked to obtain consent from a pediatric patient for electroconvulsive therapy (ECT).
Which of the following is not a risk associated with ECT?Your Answer: Induction of dementia
Explanation:Side Effects and Memory Loss Associated with Electroconvulsive Therapy (ECT)
Electroconvulsive therapy (ECT) is a medical treatment that involves passing electrical currents through the brain to induce a seizure. While side effects of ECT are rare, some patients may experience memory loss. During the course of ECT, patients may have difficulty remembering newly learned information, but this typically improves in the days and weeks following treatment. However, some patients may experience partial loss of memory for events that occurred before ECT, which may take longer to recover.
Despite these potential memory issues, some patients report improved memory ability following ECT, as it can remove the amnesia associated with severe depression. It is important to note that cardiac arrhythmia may be stimulated by the electrical shock of ECT, but musculoskeletal injury is rare with adequate anesthesia.
It is also important to dispel the myth that ECT can cause dementia. Dementia is an organic illness that is not induced by ECT. Research has not found a link between ECT and dementia, but this remains an area of focus for further study. Overall, while ECT may have some potential side effects, it can be a highly effective treatment for severe depression and other mental health conditions.

A 38-year-old woman and her 14-year-old daughter are apprehended after being caught trying to destroy a statue in the town square. When asked why, they both explain how the statue comes to life and terrorizes them at night, breaking things in their house, whispering violent thoughts in their minds and urging them to kill themselves. The police officer brings them to the Emergency Department where you evaluate them. The mother is a well-known psychiatric patient, but the daughter has never been seen before.
Which of the following is most likely to acutely reverse the psychosis in at least one of the patients?Your Answer: Separate the patients
Explanation:Treatment Approach for Shared Delusional Disorder
Shared delusional disorder, also known as folie à deux, is a rare psychiatric condition where two individuals develop a paired delusion. In cases where one of the individuals has a history of psychiatric illness, separating the patients is the first step in treating the disorder. This is because the dominant force in the duo may be the source of the delusion, and separating them may resolve the delusion in the other individual.
While benzodiazepines can sedate the patients, they will not acutely reverse psychosis. Similarly, selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) are not indicated as they take time to work and are not effective in acutely reversing psychosis.
Cognitive behavioural therapy (CBT) is a treatment approach that takes time and is not effective in acutely reversing psychosis in either of the patients. Therefore, in cases of shared delusional disorder, separating the patients and providing anti-psychotic therapy to the dominant individual may be the most effective treatment approach.

A 20-year-old individual presents with obsessive thoughts about causing harm to others since moving away from home to attend college. They are particularly anxious about using the shared kitchen in their dormitory and tend to prepare and eat meals during the night to avoid contact with their roommates. After completing a Yale-Brown Obsessive Compulsive Scale (Y-BOCS), they are diagnosed with mild OCD. What treatment option would be most suitable for this individual?
Your Answer: Cognitive behavioural therapy
Explanation:For patients with mild symptoms of obsessive-compulsive disorder (OCD) and mild impairment, the recommended first-line treatment is cognitive behavioural therapy (CBT) with exposure and response prevention (ERP). While clomipramine, a tricyclic antidepressant, may be used in some cases, it is not typically the first choice. Dialectical behaviour therapy is not commonly used in the treatment of OCD, as CBT and ERP are more effective. Fluoxetine, an SSRI antidepressant, may also be used in the treatment of OCD, but is not typically the first-line treatment for mild cases.
Obsessive-compulsive disorder (OCD) is characterized by the presence of obsessions and/or compulsions that can cause significant functional impairment and distress. Risk factors include family history, age, pregnancy/postnatal period, and history of abuse, bullying, or neglect. Treatment options include low-intensity psychological treatments, SSRIs, and more intensive CBT (including ERP). Severe cases should be referred to the secondary care mental health team for assessment and may require combined treatment with an SSRI and CBT or clomipramine as an alternative. ERP involves exposing the patient to an anxiety-provoking situation and stopping them from engaging in their usual safety behavior. Treatment with SSRIs should continue for at least 12 months to prevent relapse and allow time for improvement.

A 25-year-old male presents in clinic, insisting that you diagnose his colon issues. He describes experiencing vague sensations of incomplete stool passage and is worried that he may have a tumor causing obstruction. He reports regular bowel movements and denies any episodes of diarrhea or constipation. There is no history of blood in his stool, unintentional weight loss, or loss of appetite. He has no family history of cancer. After discussing your negative findings, he abruptly leaves the office, stating, You're just like the other four doctors I've seen, all incompetent and willing to let me die.
What is the most accurate description of his gastrointestinal (GI) symptoms?Your Answer: Hypochondriasis
Explanation:Understanding Hypochondriasis: A Case Study
A 21-year-old man is convinced that he has an occult GI malignancy, despite having no signs, symptoms, or family history of such a problem. He has seen three doctors who have told him otherwise, but he persists in his belief and is now doctor shopping by seeing four doctors for the same issue. This behavior is a classic sign of hypochondria.
Hypochondriasis is a condition where a person is excessively worried about having a serious illness, despite having no or minimal symptoms. The fear and anxiety associated with this condition can be debilitating and can interfere with a person’s daily life. In this case, the patient’s fixation on a particular disease is causing him distress and leading him to seek out multiple doctors for reassurance.
It is important to note that hypochondriasis is not the same as somatisation disorder, which refers to patients with a constellation of physical complaints that cannot be explained by a somatic process. While the patient in this case is fixated on a particular disease, he does not fit the criteria for somatisation.
It is also important to rule out other conditions, such as acute stress disorder or conversion disorder, which can present with similar symptoms. Acute stress disorder is an anxiety condition that is precipitated by an acute stressor and resolves within a month. Conversion disorder is a neurological deficit in the absence of a somatic cause and is usually preceded by a psychosocial stressor.
In conclusion, understanding hypochondriasis and its symptoms is crucial in providing appropriate care for patients who may be suffering from this condition. It is important to approach these patients with empathy and understanding, while also ruling out other potential conditions.

A 33-year-old woman, accompanied by her husband, visits her GP with unusual behaviour. Her husband reports that the changes have occurred mostly in the past week and he has never seen this behaviour before. He describes finding her walking around the house and talking to people who are not there. During the consultation, the patient appears distracted and occasionally smiles and waves at the wall behind the GP. There is no personal or family history of psychiatric illness. The patient does not seem distressed and politely asks if she can leave as she believes the appointment is a waste of time.
The patient takes loratadine 10 mg once daily for hay-fever, salbutamol and beclomethasone inhalers for asthma, and has recently started a combined oral contraceptive pill for contraception. She is also taking a course of prednisolone tablets following a recent exacerbation of her asthma. Which medication is most likely to be causing her symptoms?Your Answer: Loratadine
Correct Answer: Prednisolone
Explanation:When a person experiences sudden onset psychosis after taking corticosteroids, it is important to consider the possibility of steroid-induced psychosis. Although both the beclomethasone inhaler and prednisolone are corticosteroids, the higher dose of prednisolone makes it the more likely culprit for the patient’s symptoms.
Understanding Psychosis
Psychosis is a term used to describe a person’s experience of perceiving things differently from those around them. This can manifest in various ways, including hallucinations, delusions, thought disorganization, alogia, tangentiality, clanging, and word salad. Associated features may include agitation/aggression, neurocognitive impairment, depression, and thoughts of self-harm. Psychotic symptoms can occur in a range of conditions, such as schizophrenia, depression, bipolar disorder, puerperal psychosis, brief psychotic disorder, neurological conditions, and drug use. The peak age of first-episode psychosis is around 15-30 years.

A 30-year-old man is brought to his psychiatrist by his sister. His sister is worried that her brother firmly believes that he is a superhero, despite having no evidence or abilities to support this belief. Upon assessment, the man appears physically healthy. There are no signs of delusions, disorientation, or unusual speech patterns. However, he maintains an unyielding conviction that Beyonce is in live with him. What is the appropriate diagnosis for this condition?
Your Answer: De Clerambault's syndrome
Explanation:The correct term for the delusion that a famous person is in love with someone, without any other psychotic symptoms, is De Clerambault’s syndrome. Capgras syndrome, on the other hand, refers to the delusion that a close relative has been replaced by an impostor, while De Frégoli syndrome is the delusion of seeing a familiar person in different individuals.
De Clerambault’s Syndrome: A Delusional Belief in Famous Love
De Clerambault’s syndrome, also known as erotomania, is a type of paranoid delusion that has a romantic aspect. Typically, the patient is a single person who firmly believes that a well-known person is in love with them. This condition is characterized by a persistent and irrational belief that the famous person is sending secret messages or signals of love, even though there is no evidence to support this belief. The patient may engage in behaviors such as stalking, sending letters or gifts, or attempting to contact the object of their affection. Despite repeated rejections or lack of response, the patient remains convinced of the love affair. This syndrome can be distressing for both the patient and the object of their delusion, and it often requires psychiatric treatment.

Which of the following types of learning behaviour in the woman does this represent?Your Answer: Social learning
Explanation:Understanding Different Types of Learning
Learning is a complex process that can occur in various ways. Here are some of the different types of learning:
Social Learning: This type of learning occurs when individuals observe and assimilate the behaviors of others. It is non-verbal and not dependent on reinforcement, which can make it resistant to change.
Classical Conditioning: This type of learning occurs through associations between an environmental stimulus and a naturally occurring stimulus.
Cognitive Learning: This theory explains how mental processes are influenced by internal and external factors to produce learning in individuals.
Imprinting: This type of learning occurs at a particular age or life stage and is rapid and apparently independent of the consequences of behavior.
Operant Conditioning: This type of learning occurs when the strength of a behavior is modified by its consequences, such as reward or punishment.
Understanding these different types of learning can help us better understand how individuals acquire and modify behaviors.

Which of the following personality disorders most accurately describes her?Your Answer: Histrionic personality disorder
Correct Answer: Borderline personality disorder
Explanation:Understanding Personality Disorders: Clusters and Traits
Personality disorders can be categorized into three main clusters based on their characteristics. Cluster A includes odd or eccentric personalities such as schizoid and paranoid personality disorder. Schizoid individuals tend to be emotionally detached and struggle with forming close relationships, while paranoid individuals are suspicious and distrustful of others.
Cluster B includes dramatic, erratic, or emotional personalities such as borderline and histrionic personality disorder. Borderline individuals often have intense and unstable relationships, exhibit impulsive behavior, and may have a history of self-harm or suicide attempts. Histrionic individuals are attention-seeking, manipulative, and tend to be overly dramatic.
Cluster C includes anxious personalities such as obsessive-compulsive personality disorder. These individuals tend to be perfectionists, controlling, and overly cautious.
Understanding the different clusters and traits associated with personality disorders can help individuals recognize and seek appropriate treatment for themselves or loved ones.

You are on a pediatric liaison rotation, and have been asked to talk to a 6-year-old patient with known ADHD. Upon trying to take a history from him, you struggle to follow his train of thought, as he keeps saying things like: 'I like pizza, it's so cheesy and easy -- my dog is brown, he likes to run around -- I have a blue pencil, it's my favorite utensil -'. You suspect that his thought process is characterized by rapid shifts from one idea to another without any apparent connection.
What is the medical term for this psychiatric symptom?Your Answer: Clang associations
Explanation:White kite, bright light, tight fight – these are examples of clang associations, where words are linked by their similar sounds or rhymes. It is a symptom often seen in individuals with schizophrenia or bipolar disorder. However, this patient is not currently displaying any signs of psychosis or mania. It is important to note that aphasic speech, where the patient loses the ability to form language, and echolalia, where they repeat words or phrases of others, are different from clang associations.
Thought disorders can manifest in various ways, including circumstantiality, tangentiality, neologisms, clang associations, word salad, Knight’s move thinking, flight of ideas, perseveration, and echolalia. Circumstantiality involves providing excessive and unnecessary detail when answering a question, but eventually returning to the original point. Tangentiality, on the other hand, refers to wandering from a topic without returning to it. Neologisms are newly formed words, often created by combining two existing words. Clang associations occur when ideas are related only by their similar sounds or rhymes. Word salad is a type of speech that is completely incoherent, with real words strung together into nonsensical sentences. Knight’s move thinking is a severe form of loosening of associations, characterized by unexpected and illogical leaps from one idea to another. Flight of ideas is a thought disorder that involves jumping from one topic to another, but with discernible links between them. Perseveration is the repetition of ideas or words despite attempts to change the topic. Finally, echolalia is the repetition of someone else’s speech, including the question that was asked.

A 29-year-old man experiences a sudden emergence of auditory hallucinations describing his actions. He also firmly believes that he has been chosen by a divine entity as a prophet, which contradicts his religious convictions. During the mental state examination, the patient exhibits tangentiality and clanging. After a fortnight, the patient's symptoms disappear entirely. The patient had a history of depression during his late adolescence, but no prior comparable incidents. What disorder did this patient have?
Your Answer: Brief psychotic disorder
Explanation:The patient experienced psychosis, including hallucinations, delusions, and thought disorganisation. The correct diagnosis is brief psychotic disorder, which refers to a short-lived episode of psychosis followed by a return to normal functioning. Bipolar affective disorder is an incorrect diagnosis as there are no signs of manic episodes. Drug abuse is also an unlikely cause as there is no evidence of drug use in the patient’s history. Schizoaffective disorder is also an incorrect diagnosis as it involves both psychotic and mood symptoms occurring together, which is not the case for this patient.

A 35-year-old woman has been diagnosed with paranoid schizophrenia and prescribed clozapine for the past three months. She is due for a review appointment and has had regular blood tests. What is the primary abnormality she is at risk for?
Your Answer: Increased potassium
Correct Answer: Decreased leukocytes
Explanation:Monitoring of FBC is crucial in patients taking clozapine due to the potential life-threatening side effect of agranulocytosis/neutropenia. This condition is characterized by a significant decrease in white blood cell count, particularly neutrophils. Therefore, a decrease in leukocytes will be observed in the blood test results. Clozapine is commonly used in the treatment of schizophrenia that is resistant to other therapies.
Atypical antipsychotics are now recommended as the first-line treatment for patients with schizophrenia, as per the 2005 NICE guidelines. These medications have the advantage of significantly reducing extrapyramidal side-effects. However, they can also cause adverse effects such as weight gain, hyperprolactinaemia, and in the case of clozapine, agranulocytosis. The Medicines and Healthcare products Regulatory Agency has issued warnings about the increased risk of stroke and venous thromboembolism when antipsychotics are used in elderly patients. Examples of atypical antipsychotics include clozapine, olanzapine, risperidone, quetiapine, amisulpride, and aripiprazole.
Clozapine, one of the first atypical antipsychotics, carries a significant risk of agranulocytosis and requires full blood count monitoring during treatment. Therefore, it should only be used in patients who are resistant to other antipsychotic medication. The BNF recommends introducing clozapine if schizophrenia is not controlled despite the sequential use of two or more antipsychotic drugs, one of which should be a second-generation antipsychotic drug, each for at least 6-8 weeks. Adverse effects of clozapine include agranulocytosis, neutropaenia, reduced seizure threshold, constipation, myocarditis, and hypersalivation. Dose adjustment of clozapine may be necessary if smoking is started or stopped during treatment.

A 28-year-old man visits his General Practitioner on the advice of the Community Psychiatric Nurse. He has been experiencing a fever and sore throat lately. He is currently on clozapine for treatment-resistant schizophrenia.
What would be the most crucial investigation to conduct, considering his recent symptoms?Your Answer: Full blood count
Explanation:When treating patients with clozapine, it is important to monitor for agranulocytosis, a rare but potentially fatal side-effect. Patients should report flu-like symptoms and undergo regular blood tests. In this case, the patient’s sore throat and fever may indicate agranulocytosis, so a full blood count is necessary. While an ECG should be done before starting antipsychotic treatment, it is not the most important test in this scenario. Blood glucose should be monitored to exclude organic causes and hyperglycemia caused by antipsychotics. Liver function and urea/electrolytes should also be monitored regularly, but are not the most important tests to conduct immediately in this case.

A 28-year-old male with depression is evaluated by his psychiatrist. He expresses his ongoing depressed mood and shares with his psychiatrist that he experiences a sense of detachment from reality.
Which term best describes the abnormality exhibited by the patient?Your Answer: Derealisation
Correct Answer: Depersonalisation
Explanation:Depersonalisation and Derealisation
Depersonalisation and derealisation are two distinct experiences that can occur in individuals with mental health conditions. Depersonalisation refers to the feeling that one’s own self is not real, while derealisation refers to the feeling that the world around them is not real.
In depersonalisation, individuals may feel as though they are observing themselves from outside of their body or that they are disconnected from their thoughts and emotions. This can be a distressing experience and may lead to feelings of detachment and isolation.
On the other hand, derealisation can cause individuals to feel as though the world around them is unreal or dreamlike. This can lead to feelings of confusion and disorientation, as well as difficulty with concentration and memory.
It is important to note that these experiences can occur in a variety of mental health conditions, including anxiety, depression, and dissociative disorders. While anhedonia, delusions of guilt, and reduced affect display may be present in some individuals with depression, they are not necessarily associated with depersonalisation or derealisation.
Overall, these experiences can help individuals and their loved ones better recognize and manage symptoms of mental illness.

Question 19
Correct

A 25-year-old female presents to the emergency department with palpitations. Her ECG reveals first-degree heart block, tall P-waves, and flattened T-waves. Upon arterial blood gas analysis, her results are as follows: pH 7.55 (normal range 7.35-7.45), HCO3- 30 mmol/L (normal range 22-26 mmol/L), pCO2 5.8kPa (normal range 4.5-6kPa), p02 11kPa (normal range 10-14kPa), and Chloride 85mmol/L (normal range 95-108mmol/L). What is the underlying cause of her presentation?
Your Answer: Bulimia nervosa
Explanation:The palpitations experienced by this patient are likely due to hypokalaemia, as indicated by their ECG. The ABG results reveal a metabolic alkalosis, with low chloride levels suggesting that the cause is likely due to prolonged vomiting resulting in the loss of hydrochloric acid from the stomach. This could also explain the hypokalaemia observed on the ECG. The absence of acute nausea and vomiting suggests that this may be a chronic issue, possibly indicating bulimia nervosa as the underlying condition, unless there is a previous medical history that could account for persistent vomiting.
Bulimia Nervosa: An Eating Disorder Characterized by Binge Eating and Purging
Bulimia nervosa is a type of eating disorder that involves recurrent episodes of binge eating followed by purging behaviors such as self-induced vomiting, misuse of laxatives or diuretics, fasting, or excessive exercise. The DSM 5 diagnostic criteria for bulimia nervosa include recurrent episodes of binge eating, a sense of lack of control over eating during the episode, and recurrent inappropriate compensatory behaviors to prevent weight gain. These behaviors occur at least once a week for three months and are accompanied by an undue influence of body shape and weight on self-evaluation.
Management of bulimia nervosa involves referral for specialist care and the use of bulimia-nervosa-focused guided self-help or individual eating-disorder-focused cognitive behavioral therapy (CBT-ED). Children should be offered bulimia-nervosa-focused family therapy (FT-BN). While pharmacological treatments have a limited role, a trial of high-dose fluoxetine is currently licensed for bulimia. It is important to seek appropriate care for bulimia nervosa to prevent the physical and psychological consequences of this eating disorder.

Question 20
Incorrect
-
A 75-year-old woman is admitted to a medical ward and the medical team is concerned about her mental health in addition to her urgent medical needs. The patient is refusing treatment and insisting on leaving. The team suspects that she may be mentally incapacitated and unable to make an informed decision. Under which section of the Mental Health Act (MHA) can they legally detain her in England and Wales?
Your Answer: Section 2
Correct Answer: Section 5 (2)
Explanation:Section 5 (2) of the MHA allows a doctor to detain a patient for up to 72 hours for assessment. This can be used for both informal patients in mental health hospitals and general hospitals. During this time, the patient is assessed by an approved mental health professional and a doctor with Section 12 approval. The patient can refuse treatment, but it can be given in their best interests or in an emergency. Section 2 and 3 can only be used if they are the least restrictive method for treatment and allow for detention for up to 28 days and 6 months, respectively. Section 135 allows police to remove a person from their home for assessment, while Section 136 allows for the removal of an apparently mentally disordered person from a public place to a place of safety for assessment. Since the patient in this scenario is already in hospital, neither Section 135 nor Section 136 would apply.
