Assessment specification: :contentReference[oaicite:0]{index=0}
MCQ 1
Question:
A 21-year-old student feels tense before an important viva. The anxiety settles after the examination and does not interfere with sleep, relationships, or routine activities. Which additional finding would most strongly suggest that the anxiety has become pathological rather than a normal response?
Options:
Awareness of an approaching examination
Transient autonomic arousal before assessment
Persistent disproportionate distress with functional impairment
Temporary improvement after the examination ends
Mild apprehension about academic performance
Correct Answer: Persistent disproportionate distress with functional impairment
Explanation: Anxiety becomes clinically abnormal when its severity or persistence is disproportionate and it significantly interferes with normal functioning.
MCQ 2
Question:
A man with marked fear of dogs crosses the road whenever he sees one. His anxiety falls immediately after avoiding the animal, but over several months he becomes increasingly unable to walk through areas where dogs may be present. Which process most likely maintains his fear?
Options:
Gradual reduction of autonomic responsiveness
Increasing tolerance of the feared stimulus
Loss of memory for previous fear episodes
Development of generalized physiological arousal
Temporary relief reinforcing future avoidance
Correct Answer: Temporary relief reinforcing future avoidance
Explanation: Avoidance rapidly lowers anxiety, so the relief reinforces further avoidance and prevents corrective learning that the feared situation can be tolerated.
MCQ 3
Question:
Two patients experience episodes of intense fear with palpitations and trembling. In one patient the episodes repeatedly occur when approaching a particular animal, while in the other they arise without a consistent external trigger. Which feature most strongly supports panic disorder in the second patient?
Options:
Presence of prominent autonomic symptoms
Attacks occurring unexpectedly without a consistent trigger
Development of trembling during episodes
Presence of marked subjective fear
Temporary desire to leave the situation
Correct Answer: Attacks occurring unexpectedly without a consistent trigger
Explanation: Panic disorder is characterized by recurrent unexpected attacks, whereas phobic anxiety is predictably linked to a particular stimulus or situation.
MCQ 4
Question:
A student avoids giving case presentations but travels comfortably on crowded buses. Another patient uses buses only when accompanied because he fears being unable to leave quickly if severe anxiety develops. Which feature best distinguishes the student’s disorder from the second patient’s disorder?
Options:
Preference for remaining at home
Occurrence of physical anxiety symptoms
Fear arising in public settings
Concern about scrutiny and embarrassment
Relief after leaving an anxiety-provoking situation
Correct Answer: Concern about scrutiny and embarrassment
Explanation: Social anxiety centers on negative evaluation and embarrassment, whereas agoraphobic fear centers on difficulty escaping or obtaining help.
MCQ 5
Question:
A 46-year-old patient reports episodes of sweating, tremulousness, palpitations, irritability, and intense uneasiness before meals. Symptoms improve rapidly after eating. Which interpretation is most appropriate before considering a primary anxiety disorder?
Options:
Hypoglycemia-related autonomic symptoms
Dissociative neurological dysfunction
Specific situational phobia
Persistent somatoform pain disorder
Primary social anxiety disorder
Correct Answer: Hypoglycemia-related autonomic symptoms
Explanation: Hypoglycemia can produce sympathetic symptoms that resemble anxiety; the temporal relation to fasting and improvement after food are important clues.
MCQ 6
Question:
A man develops marked anxiety, tremor, sweating, and insomnia two days after abruptly stopping prolonged use of a sedative substance. He previously had no persistent anxiety symptoms. Which explanation best fits the presentation?
Options:
New-onset specific phobia
Primary generalized anxiety
Withdrawal-related autonomic overactivity
Somatoform autonomic dysfunction
Dissociative behavioural disturbance
Correct Answer: Withdrawal-related autonomic overactivity
Explanation: Withdrawal from alcohol or sedative drugs may produce prominent anxiety with autonomic activation, so substance history is essential when assessing new anxiety.
MCQ 7
Question:
A patient repeatedly interprets harmless palpitations during anxiety as evidence that he is about to collapse. Medical evaluation is reassuring. The clinician explains how anxiety itself can produce autonomic symptoms and how fearful interpretation can intensify them. What is the main therapeutic purpose of this explanation?
Options:
Suppress physiological arousal pharmacologically
Remove all external sources of stress
Produce temporary emotional numbing
Prevent awareness of bodily sensations
Reduce catastrophic interpretation of anxiety symptoms
Correct Answer: Reduce catastrophic interpretation of anxiety symptoms
Explanation: Psychoeducation helps patients understand that bodily symptoms can arise from anxiety, reducing fear of the sensations and the cycle of escalating anxiety.
MCQ 8
Question:
A patient has persistent anxiety that is interfering with work and relationships. Brief reassurance and self-directed relaxation have provided little benefit. Which management plan best addresses both the ongoing anxiety symptoms and the cognitive-behavioural factors maintaining the disorder?
Options:
Long-term benzodiazepine treatment alone
CBT combined with SSRI-based treatment
Beta-blocker therapy as sole treatment
Repeated medical investigation without therapy
Avoidance of anxiety-provoking activities
Correct Answer: CBT combined with SSRI-based treatment
Explanation: Persistent functionally impairing anxiety may require both psychological treatment targeting maladaptive thoughts and behaviour and appropriate long-term pharmacotherapy.
MCQ 9
Question:
A young woman presents with intermittent loss of power in one limb. Examination demonstrates a reproducible functional pattern that does not correspond to an anatomical lesion, and appropriate neurological assessment is reassuring. Which approach best supports the diagnosis?
Options:
Assuming psychological stress proves the diagnosis
Waiting indefinitely for every possible disease to be excluded
Interpreting normal imaging as proof of fabrication
Identifying a positive functional clinical pattern after assessment
Classifying every unexplained symptom as somatoform
Correct Answer: Identifying a positive functional clinical pattern after assessment
Explanation: Dissociative neurological symptoms should be recognized from a positive clinical pattern after suitable medical assessment, not merely diagnosed because tests are normal.
MCQ 10
Question:
A 55-year-old develops new unilateral weakness soon after a major family conflict. A relative suggests that stress makes further neurological assessment unnecessary. Which clinical principle is most appropriate?
Options:
Evaluate for genuine neurological disease before psychiatric attribution
Classify the symptom as dissociative because stress preceded it
Begin psychotherapy before completing clinical assessment
Assume the symptom is voluntarily produced
Avoid physical examination to prevent reinforcement
Correct Answer: Evaluate for genuine neurological disease before psychiatric attribution
Explanation: Psychological stress can coexist with organic disease; a dissociative diagnosis must not be used to dismiss a potentially genuine neurological disorder.
MCQ 11
Question:
A patient periodically enters an altered state of awareness with marked behavioural change and later has limited recall of the episode. The behaviour is not part of a culturally accepted religious or social practice, and no neurological explanation is identified. Which presentation is most consistent with this pattern?
Options:
Generalized anxiety presentation
Dissociative trance or possession presentation
Persistent somatoform pain presentation
Specific phobic presentation
Adjustment-related presentation
Correct Answer: Dissociative trance or possession presentation
Explanation: Dissociation may present with altered awareness and behaviour resembling trance or possession when the state is not better explained by cultural practice or another disorder.
MCQ 12
Question:
A patient describes episodes in which his usual sense of self becomes disrupted and different patterns of identity and behaviour appear to take control. Which aspect of normal psychological integration is primarily disturbed?
Options:
Autonomic cardiovascular regulation
Fear conditioning to an external object
Physiological response to hyperventilation
Appraisal of environmental stressors
Continuity and integration of identity
Correct Answer: Continuity and integration of identity
Explanation: Dissociation can disrupt the normally integrated experience of identity, memory, awareness, perception, sensation, or voluntary function.
MCQ 13
Question:
A woman undergoing treatment for a dissociative disorder also develops persistent low mood, loss of interest, and impaired functioning. Her neurological-type symptoms are improving with rehabilitation. Which additional management principle is most appropriate?
Options:
Stop rehabilitation until mood symptoms resolve
Ignore mood symptoms because dissociation explains them
Treat associated depression alongside dissociative management
Repeat neurological investigations before addressing mood
Explain that psychiatric comorbidity excludes dissociation
Correct Answer: Treat associated depression alongside dissociative management
Explanation: Dissociative management includes recognition and treatment of associated psychiatric problems such as anxiety or depression when present.
MCQ 14
Question:
Several months after a serious road accident, a patient takes a much longer route to work to avoid the crash site and refuses to discuss the event with relatives. Which trauma-related symptom process is being demonstrated most clearly?
Options:
Avoidance of trauma reminders
Generalized autonomic dysfunction
Dissociative loss of identity
Somatic preoccupation with illness
Fear of social evaluation
Correct Answer: Avoidance of trauma reminders
Explanation: Avoiding locations, conversations, and other reminders associated with severe trauma is an important trauma-related symptom pattern.
MCQ 15
Question:
A patient with persistent trauma-related symptoms reports that he has recently begun drinking heavily each evening to help himself sleep. Which additional component should be included in his psychiatric assessment?
Options:
Assessment of visual-field defects
Assessment for endocrine malignancy
Assessment of dissociative motor weakness
Assessment of associated substance misuse
Assessment for specific animal phobia
Correct Answer: Assessment of associated substance misuse
Explanation: Persistent stress-related disorders may coexist with harmful substance use, which should be actively recognized because it can worsen symptoms and recovery.
MCQ 16
Question:
A healthcare worker feels tearful, tense, and distracted for two days after witnessing a disturbing event. She remains able to work, sleeps reasonably, has strong family support, and is already improving. Which approach best reflects an appropriate stress-management principle?
Options:
Diagnose a chronic stress-related disorder immediately
Provide support without prematurely medicalizing brief distress
Start long-term pharmacotherapy despite improvement
Recommend complete avoidance of normal activity
Arrange repeated physical investigations
Correct Answer: Provide support without prematurely medicalizing brief distress
Explanation: Short-lived stress responses may resolve with reassurance and support; psychiatric treatment should be proportionate to persistence, severity, and functional impairment.
MCQ 17
Question:
A trauma-exposed patient has received appropriate psychological support, but several weeks later continues to have marked anxiety and depressive symptoms that substantially impair daily functioning. Which pharmacological principle is most appropriate?
Options:
Medication should replace all psychological treatment
Medication is indicated after every stressful event
Sedatives should be continued indefinitely
Drug therapy is inappropriate in stress-related disorders
Medication may be considered for persistent clinically significant symptoms
Correct Answer: Medication may be considered for persistent clinically significant symptoms
Explanation: Pharmacotherapy may be appropriate when persistent anxiety or depressive symptoms remain clinically important, while psychological management continues.
MCQ 18
Question:
Two patients repeatedly seek medical care despite reassuring assessments. One mainly fears that an undetected serious disease is present, whereas the other reports recurrent pain, gastrointestinal symptoms, fatigue, and other bodily complaints affecting several systems. Which feature most strongly favors the second patient’s pattern?
Options:
Persistent fear of one serious diagnosis
Concern about medical reassurance being incorrect
Multiple recurrent bodily complaints across several systems
Preoccupation with having a single severe illness
Repeated requests for confirmation of one diagnosis
Correct Answer: Multiple recurrent bodily complaints across several systems
Explanation: Traditional somatization is dominated by multiple recurrent physical symptoms, whereas hypochondriacal illness is dominated by persistent disease preoccupation.
MCQ 19
Question:
One patient has recurrent abdominal, cardiovascular, and musculoskeletal complaints without sufficient organic explanation. Another develops an isolated loss of sensation in one limb with a functional pattern not explained by neurological anatomy. Which feature most strongly points toward a dissociative neurological presentation in the second patient?
Options:
Focal motor or sensory dysfunction without an explanatory lesion
Multiple complaints affecting unrelated organ systems
Persistent concern about an undiagnosed disease
Long-standing medically unexplained abdominal symptoms
Repeated consultations for diffuse bodily symptoms
Correct Answer: Focal motor or sensory dysfunction without an explanatory lesion
Explanation: Dissociative neurological disorders characteristically present with functional neurological-type deficits, while somatoform disorders more commonly involve bodily symptom complaints.
MCQ 20
Question:
A patient with medically unexplained bodily symptoms becomes increasingly focused on minor changes in heart rate and abdominal sensations. Each sensation is interpreted as evidence that something serious has been missed, and the perceived severity of symptoms increases. Which principle best explains this pattern?
Options:
Normal investigations eliminate the experience of symptoms
Physical symptoms require demonstrable structural pathology
Psychological symptoms cannot alter bodily perception
Heightened bodily attention can amplify perceived symptom intensity
Unexplained symptoms indicate deliberate symptom production
Correct Answer: Heightened bodily attention can amplify perceived symptom intensity
Explanation: Increased attention to normal or minor bodily sensations and illness-related concern can magnify their perceived intensity and clinical significance.
