1. A patient presents with a 6-month history of pervasive, intrusive thoughts about contamination,
leading to elaborate hand-washing rituals that occupy over 3 hours daily. The patient
acknowledges these thoughts are excessive but feels unable to stop. A comorbid pattern of
symmetrical ordering and counting behaviors is noted. Which neurobiological mechanism is most
directly implicated in the maintenance of this patient's symptoms?
A. Hyperactivity of the orbitofrontal cortex and caudate nucleus within the cortico-striato-thalamo-cortical
(CSTC) circuit
B. Reduced gray matter volume in the dorsolateral prefrontal cortex and amygdala
C. Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis with elevated cortisol levels
D. Decreased serotonin transporter binding in the raphe nuclei and prefrontal cortex
Answer: A
Rationale: OCD is characterized by hyperactivity in the CSTC circuit, specifically the orbitofrontal
cortex and caudate, leading to repetitive behaviors. Option B is more associated with depression or
PTSD, not OCD. HPA axis dysregulation (C) is seen in stress-related disorders. While serotonin
dysfunction (D) is implicated in OCD treatment response, the direct neurocircuitry mechanism is CSTC
hyperactivity.
2. A therapist is treating a patient with a history of childhood emotional neglect and current
difficulties with emotional regulation, chronic emptiness, and unstable relationships. The therapist
focuses on validating the patient's experiences, helping the patient identify and label emotions, and
teaching distress tolerance skills. Which theoretical orientation is the therapist primarily using?
A. Dialectical Behavior Therapy (DBT)
B. Cognitive Behavioral Therapy (CBT)
C. Psychodynamic Psychotherapy
D. Humanistic/Client-Centered Therapy
Answer: A
Rationale: DBT explicitly combines validation, emotion identification, and distress tolerance skills,
originally developed for borderline personality disorder (which matches the described symptoms). CBT
(B) focuses more on cognitive restructuring and behavioral activation. Psychodynamic (C) emphasizes
unconscious conflicts and transference. Humanistic (D) centers on unconditional positive regard and
empathy but lacks structured skill-building.

,3. A 30-year-old individual with no prior psychiatric history is brought to the emergency
department after being found wandering aimlessly, speaking rapidly with flight of ideas, and
exhibiting grandiose delusions about being a prophet. Over the past week, the patient has slept
only 2 hours per night, engaged in impulsive spending, and displayed hypersexuality. Urine
toxicology is negative. Which of the following is the most appropriate first-line pharmacotherapy
for acute management?
A. Lithium carbonate
B. Olanzapine
C. Valproic acid
D. Quetiapine
Answer: B
Rationale: Acute mania with psychotic features requires rapid stabilization. Atypical antipsychotics like
olanzapine are first-line for acute mania due to rapid onset and efficacy against psychotic symptoms.
Lithium (A) and valproic acid (C) are mood stabilizers but have slower onset (days to weeks) and are
less effective for acute psychotic features. Quetiapine (D) is also used but olanzapine is preferred in
acute settings with severe agitation.
4. A 45-year-old patient with a history of recurrent major depressive episodes is started on a
selective serotonin reuptake inhibitor (SSRI). After 4 weeks, the patient reports no significant
improvement in mood, anhedonia, or sleep. The patient also complains of new-onset sexual
dysfunction and weight gain of 5 kg. Which of the following is the most appropriate next step?
A. Discontinue the SSRI and start a monoamine oxidase inhibitor (MAOI)
B. Augment the SSRI with a low dose of aripiprazole
C. Switch to a different SSRI (e.g., from fluoxetine to sertraline)
D. Increase the SSRI dose to the maximum recommended
Answer: B
Rationale: After 4 weeks of inadequate response and tolerability issues, augmentation with a
second-generation antipsychotic (e.g., aripiprazole) is evidence-based for treatment-resistant
depression. Switching to another SSRI (C) may yield similar side effects and limited efficacy. MAOIs (A)
are reserved for refractory cases due to dietary restrictions and safety concerns. Increasing dose (D)
may worsen side effects without robust evidence for efficacy after partial response.
5. A 25-year-old graduate student reports recurrent, sudden episodes of intense fear accompanied
by palpitations, sweating, trembling, shortness of breath, and a fear of dying. These episodes occur
without warning, and the patient now avoids crowded places, public transportation, and being
alone outside the home. Which of the following best describes the primary mechanism underlying
the maintenance of this disorder?
A. Classical conditioning of fear to interoceptive cues and negative reinforcement through avoidance
B. Operant conditioning of safety behaviors reinforced by reduced anxiety
C. Cognitive misinterpretation of bodily sensations as catastrophic
D. Dysregulation of the locus coeruleus-norepinephrine system leading to spontaneous panic
Answer: A
Rationale: Panic disorder with agoraphobia is maintained by classical conditioning: panic attacks
become associated with internal (interoceptive) cues, and avoidance (negative reinforcement) reduces
Page 2
,fear but prevents extinction. Option B describes safety behaviors but not the initial conditioning. Option
C is a cognitive model component but not the primary maintenance mechanism. Option D is a biological
vulnerability but not the maintenance mechanism.
6. A 60-year-old patient with a 20-year history of alcohol use disorder (currently abstinent for 6
months) presents with progressive memory impairment, confabulation, and difficulty learning new
information. Neurological exam reveals nystagmus and ataxia. MRI shows atrophy of the
mammillary bodies and thalamus. Which of the following is the most likely diagnosis?
A. Alzheimer's disease
B. Wernicke-Korsakoff syndrome
C. Frontotemporal dementia
D. Vascular dementia
Answer: B
Rationale: Wernicke-Korsakoff syndrome is caused by thiamine deficiency, often in alcohol use disorder,
and presents with confabulation, memory deficits, nystagmus, ataxia, and characteristic brain changes
(mammillary body atrophy). Alzheimer's (A) typically shows hippocampal atrophy and no confabulation.
Frontotemporal (C) presents with personality changes and language deficits. Vascular (D) has stepwise
decline and focal neurological signs.
7. A 35-year-old patient with schizophrenia has persistent auditory hallucinations and delusions
despite adequate trials of two different antipsychotics at therapeutic doses for 8 weeks each. The
patient is currently on clozapine 300 mg/day for 12 weeks with only partial response. Which of the
following is the most appropriate next step in pharmacotherapy?
A. Augment clozapine with electroconvulsive therapy (ECT)
B. Switch to a long-acting injectable (LAI) antipsychotic
C. Increase clozapine dose to 450 mg/day and monitor serum levels
D. Add a second antipsychotic such as risperidone to clozapine
Answer: C
Rationale: Clozapine is the gold standard for treatment-resistant schizophrenia, but doses often need to
be optimized. Increasing to 450 mg/day (with serum level monitoring) is appropriate before considering
augmentation. ECT (A) is reserved for severe refractory cases. LAI (B) is not first-line for clozapine
partial response. Adding a second antipsychotic (D) has limited evidence and increases side effects.
8. A 28-year-old patient with a history of childhood sexual abuse presents with recurrent
nightmares, flashbacks, hypervigilance, and avoidance of reminders of the trauma. The patient
also reports significant guilt about the event and has a comorbid diagnosis of major depressive
disorder. Which of the following is the most evidence-based psychotherapeutic approach for this
patient?
A. Eye Movement Desensitization and Reprocessing (EMDR)
B. Prolonged Exposure (PE) therapy
C. Cognitive Processing Therapy (CPT)
D. Trauma-Focused Cognitive Behavioral Therapy (TF-CBT)
Page 3
, Answer: C
Rationale: CPT is specifically designed to address trauma-related guilt and comorbid depression, as it
focuses on challenging maladaptive beliefs (e.g., self-blame) and restructuring cognitions. EMDR (A) is
effective but less directly targets guilt. Prolonged Exposure (B) focuses on habituation to feared stimuli
and may not adequately address guilt. TF-CBT (D) is primarily for children and adolescents, not adults.
9. A 22-year-old patient with a diagnosis of anorexia nervosa, restricting type, is admitted for
medical stabilization due to a BMI of 14.5 and bradycardia (heart rate 42 bpm). Which of the
following is the most critical initial intervention to prevent refeeding syndrome?
A. Start nasogastric feeding at 1500 kcal/day with electrolyte monitoring
B. Initiate oral refeeding at 2000 kcal/day with phosphorus supplementation
C. Begin intravenous fluids and monitor glucose every 4 hours
D. Start nasogastric feeding at 500 kcal/day with electrolyte and phosphorus monitoring
Answer: D
Rationale: Refeeding syndrome is a life-threatening metabolic complication in severely malnourished
patients. Initial refeeding should be low-calorie (e.g., 500-800 kcal/day) with close monitoring of
electrolytes (especially phosphorus, magnesium, potassium) and supplementation as needed. Option A
and B are too high in calories initially. Option C alone does not address nutritional needs and may not
prevent refeeding syndrome.
10. A 55-year-old patient with a history of hypertension and type 2 diabetes is started on
venlafaxine XR 75 mg daily for major depressive disorder. After 2 weeks, the patient's blood
pressure increases from 135/85 to 155/95 mmHg. Which of the following is the most appropriate
management?
A. Discontinue venlafaxine and start a different antidepressant with lower cardiovascular risk
B. Add a beta-blocker such as propranolol to control blood pressure
C. Increase venlafaxine dose to 150 mg daily to achieve therapeutic effect
D. Continue venlafaxine at same dose and monitor blood pressure weekly
Answer: A
Rationale: Venlafaxine, especially at higher doses, can cause sustained hypertension due to
norepinephrine reuptake inhibition. In a patient with pre-existing hypertension and diabetes, a
significant increase in BP warrants a switch to an antidepressant with a more favorable cardiovascular
profile (e.g., SSRIs, bupropion). Adding a beta-blocker (B) may mask symptoms but does not address the
cause. Increasing dose (C) would worsen hypertension. Continuing with monitoring (D) is inadequate
given the acute rise.
11. A 35-year-old individual with a history of childhood emotional neglect presents with chronic
feelings of emptiness, intense fear of abandonment, and a pattern of unstable relationships. Which
theoretical framework best explains the etiology of these symptoms, and what neurobiological
correlate is most associated?
A. Attachment theory; reduced hippocampal volume
B. Cognitive-behavioral model; prefrontal cortex hyperactivity
C. Dialectical behavior therapy; amygdala hyporeactivity
