During an out of hours shift, you are called to see an 80-year-old man who has developed acute urinary retention on a background of 3 years of urinary hesitancy and poor stream. He has a history of ischaemic heart disease, hypertension and he tells you that his usual GP has recently started him on a new medication for neuropathic pain. Which of the following drugs is most likely to have precipitated the urinary retention?
Your Answer: Diazepam
Correct Answer: Amitriptyline
Explanation:Urinary retention may be a side effect of tricyclic antidepressants, particularly with the use of Amitriptyline due to its anticholinergic properties. This can lead to symptoms such as tachycardia, dry mouth, and mydriasis. However, SSRIs like fluoxetine and SNRIs like venlafaxine are less likely to cause urinary retention and dry mouth. Benzodiazepines like diazepam do not have anticholinergic effects.
Tricyclic Antidepressants for Neuropathic Pain
Tricyclic antidepressants (TCAs) were once commonly used for depression, but their side-effects and toxicity in overdose have led to a decrease in their use. However, they are still widely used in the treatment of neuropathic pain, where smaller doses are typically required. TCAs such as low-dose amitriptyline are commonly used for the management of neuropathic pain and the prophylaxis of headache, while lofepramine has a lower incidence of toxicity in overdose. It is important to note that some TCAs, such as amitriptyline and dosulepin, are considered more dangerous in overdose than others.
Common side-effects of TCAs include drowsiness, dry mouth, blurred vision, constipation, urinary retention, and lengthening of the QT interval. When choosing a TCA for neuropathic pain, the level of sedation may also be a consideration. Amitriptyline, clomipramine, dosulepin, and trazodone are more sedative, while imipramine, lofepramine, and nortriptyline are less sedative. It is important to work with a healthcare provider to determine the appropriate TCA and dosage for the individual’s specific needs.

A 47-year-old man visits his General Practitioner with worsening anxiety. He describes one of his symptoms as feeling severely nauseous and even vomiting every time he smells a particular perfume. What theory of learning explains this?
Your Answer: Classical conditioning
Explanation:Types of Learning and Conditioning in Psychology
Classical conditioning, latent inhibition, habituation, operant conditioning, and tolerance are all types of learning and conditioning in psychology.
Classical conditioning involves learning through association, where an unfamiliar stimulus becomes associated with a conditioned response through repetitive exposure.
Latent inhibition refers to the slower acquisition of meaning or response to a familiar stimulus compared to a new stimulus.
Habituation is the decrease in responsiveness to a stimulus with repeated exposure.
Operant conditioning involves learning through positive or negative reinforcement, where a voluntary response is followed by a reinforcing stimulus.
Tolerance is the reduced response to a drug over time, requiring a higher concentration to achieve the desired effect.

A 42-year-old accountant comes to see you for a follow-up review 2 weeks after presenting with symptoms suggesting low mood. He had felt ‘down’ for several weeks, no longer enjoyed work or seeing friends and was sleeping more than usual. Despite this, he had a normal appetite, a strong sense of self-worth, denied any thoughts of self-harm or suicide and came across as reasonably active and lively. He says that he feels very anxious on Sunday evenings before going to work on a Monday and is getting increasingly ‘short and snappy’ with his colleagues. However, he says that work is otherwise going well and he is managing to get through the day. He does not feel any better at today’s consultation and is requesting advice about treatment options. He says he is ‘not a tablet person’.
What should you advise?Your Answer: Trial of computer-based CBT or peer support, combined with an SSRI antidepressant for 6 months
Correct Answer: A trial of computer-based cognitive behavioural therapy (CBT) or peer support
Explanation:For a patient with mild depression symptoms, the recommended first-line treatment is low-intensity psychosocial interventions such as computer-based CBT, group-based CBT, or peer support groups performing physical activity programs. If the patient prefers non-pharmacological treatment, antidepressants should not be used as first-line. Benzodiazepines should be avoided due to their addictive potential and side-effect profile. In the presence of both depression and anxiety, depression should be treated first according to NICE guidelines.

A 30-year-old female with a diagnosis of bipolar disorder visits her doctor to discuss a headache. She starts explaining her issue with the following statement:
I came here to talk about this headache, but I can't stop thinking about the dream I had last night where I was flying over a rainbow. It's funny because I haven't eaten pizza in a week, and I really miss it.
What sign of thought disorder is evident in the patient's speech?Your Answer: Flight of ideas
Correct Answer: Knight's move
Explanation:The patient’s speech is indicative of thought disorder characterized by Knight’s move thinking, where there are illogical leaps from one idea to another without any discernible links between them. This is different from flight of ideas, where there are identifiable connections between ideas. It is important to note that the patient is not exhibiting neologisms or clang associations, and their speech is not a word salad.
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.

Question 5
Correct

A 28-year-old artist visits his GP complaining of anxiety related to social interactions. He prefers solitude and is hesitant to share his beliefs with others, which they find peculiar. During the consultation, the patient talks in a high-pitched voice about his fascination with horror movies and his 'spirit-guide' that protects him. However, he denies experiencing any visual or auditory hallucinations and does not display any delusional thinking. Additionally, there is no evidence of pressure of speech. What is the probable diagnosis?
Your Answer: Schizotypal personality disorder
Explanation:The man seeking help has social anxiety and prefers to be alone. He has an interest in paranormal phenomena and talks in a high-pitched voice when discussing his spirit guide. These symptoms suggest that he may have schizotypal personality disorder, which is characterized by magical thinking and odd speech patterns. Emotionally unstable personality disorder, histrionic personality disorder, schizoaffective disorder, and schizoid personality disorder are all incorrect diagnoses.
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.

A 36-year-old woman is admitted to the Emergency Department following taking approximately 18 paracetamol tablets three hours earlier. She had a row with her husband and took the tablets as she was angry and upset. She called her husband after she took the tablets, who rang for an ambulance.
This is the first time she has ever done anything like this, and she regrets the fact that she did it. She is currently studying at university, and only drinks recreationally. She is normally fit and well and has no history of mental health conditions.
Which of the following factors are associated with increased risk of a further suicide attempt in someone who has already made a suicide attempt?Your Answer: Alcohol or drug abuse, history of violence and single, divorced or separated
Explanation:Risk Factors for Repeated Suicide Attempts
Individuals who have previously attempted suicide are at an increased risk of making another attempt. Factors that contribute to this risk include a history of previous attempts, personality disorders, alcohol or drug abuse, previous psychiatric treatment, unemployment, lower social class, criminal record, history of violence, and being between the ages of 25 and 54, as well as being single, divorced, or separated. Rates of further suicide attempts in the year following an attempt are high, ranging from 15 to 25 percent. However, being married or having short stature does not appear to be a significant risk factor for repeated suicide attempts.

Question 7

A 35-year-old male contacts his GP at 2PM to schedule his blood tests following a recent visit to his psychiatrist. The psychiatrist has raised his lithium dosage and requested that the GP arrange for lithium levels to be checked at the appropriate time after taking the medication. The patient took his first increased dose of lithium at 10AM (4 hours ago). In how many hours should the GP schedule the blood test to be taken?
Your Answer: 8 hours
Explanation:Lithium is a medication used to stabilize mood in individuals with bipolar disorder and as an adjunct in treatment-resistant depression. It has a narrow therapeutic range of 0.4-1.0 mmol/L and is primarily excreted by the kidneys. The mechanism of action is not fully understood, but it is believed to interfere with inositol triphosphate and cAMP formation. Adverse effects may include nausea, vomiting, diarrhea, fine tremors, nephrotoxicity, thyroid enlargement, ECG changes, weight gain, idiopathic intracranial hypertension, leucocytosis, hyperparathyroidism, and hypercalcemia.
Monitoring of patients taking lithium is crucial to prevent adverse effects and ensure therapeutic levels. It is recommended to check lithium levels 12 hours after the last dose and weekly after starting or changing the dose until levels are stable. Once established, lithium levels should be checked every three months. Thyroid and renal function should be monitored every six months. Patients should be provided with an information booklet, alert card, and record book to ensure proper management of their medication. Inadequate monitoring of patients taking lithium is common, and guidelines have been issued to address this issue.

A 35-year-old woman is brought to the psychiatry clinic by her spouse. The spouse reports that the patient has been displaying abnormal behaviour, such as staying up all night, talking rapidly, excessive shopping, and claiming she will become a millionaire by investing in cryptocurrency.
The patient has a history of depression and is currently taking sertraline. During the mental state examination, the patient exhibits signs of overly familiar behaviour, pressured speech, and flight of ideas.
What is the best medication to treat this condition?Your Answer: Continue sertraline and add olanzapine
Correct Answer: Stop sertraline and start olanzapine
Explanation:When managing mania or hypomania in patients who are taking antidepressants, it may be necessary to discontinue the use of the antidepressant and initiate treatment with antipsychotic medication.
Understanding Bipolar Disorder
Bipolar disorder is a mental health condition that is characterized by alternating periods of mania/hypomania and depression. It typically develops in the late teen years and has a lifetime prevalence of 2%. There are two recognized types of bipolar disorder: type I, which involves mania and depression, and type II, which involves hypomania and depression.
Mania and hypomania both refer to abnormally elevated mood or irritability, but mania is more severe and can include psychotic symptoms for 7 days or more. Hypomania, on the other hand, involves decreased or increased function for 4 days or more. The presence of psychotic symptoms suggests mania.
Management of bipolar disorder may involve psychological interventions specifically designed for the condition, as well as medication. Lithium is the mood stabilizer of choice, but valproate can also be used. Antipsychotic therapy, such as olanzapine or haloperidol, may be used to manage mania/hypomania, while fluoxetine is the antidepressant of choice for depression. It is important to address any co-morbidities, as there is an increased risk of diabetes, cardiovascular disease, and COPD in individuals with bipolar disorder.
If symptoms suggest hypomania, routine referral to the community mental health team (CMHT) is recommended. However, if there are features of mania or severe depression, an urgent referral to the CMHT should be made. Understanding bipolar disorder and its management is crucial for healthcare professionals to provide appropriate care and support for individuals with this condition.

Question 9
Incorrect

A 4-year-old boy is brought to the General Practitioner (GP) by his parents due to concerns raised by his nursery. Although he is meeting his developmental milestones, he seems to struggle with social interaction and play with other children.
The parents report that he was born via normal vaginal delivery at term and has met all of his speech and motor milestones. However, they have noticed that he is different from his older siblings as he has never made any friends or engaged in any imaginative play. He prefers to play alone and becomes upset if anyone touches his toys. He insists on following the same routine every day, including eating the same meals and taking the same route to nursery. He struggles during weekends and holidays when his routine is disrupted.
Which of the following diagnoses would be most consistent with the signs and symptoms observed in this child?Your Answer: Obsessive–compulsive disorder (OCD)
Correct Answer: Autism spectrum disorder
Explanation:Understanding Different Developmental Disorders: A Comparison
When observing a child’s behavior, it is important to consider various developmental disorders that may be present. In this case, the girl in question is displaying signs of autism spectrum disorder, which is characterized by persistent difficulties with social communication and interaction, as well as restrictive and repetitive patterns of behavior. This disorder must have been present since early childhood and cause significant impairment in important areas of functioning.
It is important to differentiate autism spectrum disorder from other disorders, such as obsessive-compulsive disorder (OCD), which is characterized by the presence of obsessions and compulsions, and attention-deficit/hyperactivity disorder (ADHD), which is characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development.
Additionally, a learning disability may be considered if the child has a significantly reduced ability to understand new or complex information and learn new skills, with a reduced ability to cope independently. However, this is unlikely if the child is performing well academically.
Finally, Rett syndrome is a progressive neurological condition that is usually only seen in girls and has features similar to autism spectrum disorder, such as the inability to show feelings. However, it also has other features such as microcephaly, abnormal gait, seizures, and hypotonia, and usually presents at a much younger age.
Overall, understanding the differences between these developmental disorders is crucial in accurately identifying and addressing a child’s needs.

Question 10
Incorrect

A 30-year-old man visits his doctor six weeks after being diagnosed with generalised anxiety disorder (GAD). Despite undergoing cognitive behavioural therapy for a few sessions, his symptoms continue to significantly impact his daily routine. He inquires about the possibility of taking medication for his anxiety.
What is the primary drug class used to treat GAD?Your Answer: Selective serotonin–noradrenaline reuptake inhibitor (SNRI)
Correct Answer: Selective serotonin reuptake inhibitor (SSRI)
Explanation:The first-line pharmacological treatment for GAD, according to NICE, is selective serotonin reuptake inhibitors (SSRIs) like sertraline. Benzodiazepines should only be used for a short period during a crisis due to their association with dependence and tolerance. If SSRIs or SNRIs cannot be tolerated, pregabalin may be considered as a third-line treatment. SNRIs like venlafaxine or paroxetine are recommended as a second-line treatment. Tricyclic antidepressants are not recommended for GAD but may be effective for panic disorder, although caution should be taken in patients with a history of self-harm or suicidal ideation due to their toxicity in overdose.
