gaps, reinforce critical concepts, and build confidence before taking the actual
board exam
1. A 34-year-old female presents with persistent depressed mood, anhedonia,
fatigue, and feelings of worthlessness for the past 8 weeks. She denies
suicidal ideation. Which medication is considered first-line treatment for
Major Depressive Disorder?
A) Tricyclic antidepressants (TCAs)
B) Selective serotonin reuptake inhibitors (SSRIs)
C) Monoamine oxidase inhibitors (MAOIs)
D) Typical antipsychotics
E) Benzodiazepines
CORRECT ANSWER: B) Selective serotonin reuptake inhibitors (SSRIs)
Rationale: SSRIs are considered the gold standard first-line pharmacological
treatment for Major Depressive Disorder due to their favorable side effect profile,
safety in overdose, and efficacy. They work by inhibiting the reuptake of serotonin,
increasing its availability in the synaptic cleft. Common SSRIs include sertraline,
,fluoxetine, paroxetine, and citalopram. TCAs, while effective, have more
anticholinergic side effects and are cardiotoxic in overdose. MAOIs require dietary
restrictions and have significant drug interactions. Antipsychotics and
benzodiazepines are not first-line monotherapy for depression.
2. A 45-year-old male with a history of schizophrenia has been stable on
risperidone 4 mg daily for 2 years. He now presents with involuntary orofacial
movements, tongue protrusion, and lip smacking. What is the most likely
diagnosis?
A) Akathisia
B) Tardive dyskinesia
C) Parkinsonism
D) Neuroleptic malignant syndrome
E) Acute dystonia
CORRECT ANSWER: B) Tardive dyskinesia
Rationale: Tardive dyskinesia (TD) is a late-onset movement disorder characterized
by involuntary, repetitive orofacial movements (lip smacking, tongue protrusion,
grimacing), limb movements, and trunk movements. It occurs after prolonged
exposure to antipsychotics (typically after months to years of treatment). It is more
common with typical antipsychotics but can occur with atypicals. Akathisia is inner
restlessness. Parkinsonism involves bradykinesia and rigidity. NMS is a medical
emergency with fever. Acute dystonia occurs suddenly with sustained muscle
contractions.
3. A 28-year-old woman presents to the clinic with severe anxiety, panic
attacks, and avoidance of public places for the past 3 months. She reports
that her anxiety significantly interferes with her work and social functioning.
Which of the following is the most appropriate initial intervention?
A) Immediate psychiatric hospitalization
,B) Cognitive Behavioral Therapy (CBT)
C) Long-term benzodiazepine monotherapy
D) Antipsychotic medication
E) No treatment; observation only
CORRECT ANSWER: B) Cognitive Behavioral Therapy (CBT)
Rationale: CBT is an evidence-based, first-line psychological intervention for panic
disorder and agoraphobia. It helps patients identify and modify anxious thoughts,
develop coping strategies, and gradually face avoided situations through exposure.
While pharmacotherapy (SSRIs) is also effective and often combined with CBT,
psychotherapy alone can be effective and should be considered as an initial
intervention. Benzodiazepines are not recommended for long-term monotherapy
due to dependence and tolerance risks. Hospitalization is not indicated unless there
is severe suicidality or inability to function. Antipsychotics are not first-line for
anxiety disorders.
4. A 52-year-old male with a history of bipolar I disorder on lithium therapy
presents with coarse tremor, polyuria, and polydipsia. His serum lithium level
is 1.2 mEq/L (normal therapeutic range 0.6-1.2 mEq/L). What is the most
appropriate next step?
A) Increase lithium dose
B) Decrease lithium dose and monitor closely
C) Switch to valproate
D) Add a beta-blocker for tremor management
E) Discontinue lithium immediately
CORRECT ANSWER: B) Decrease lithium dose and monitor closely
Rationale: The patient is experiencing signs of lithium toxicity (tremor, polyuria,
polydipsia indicating nephrogenic diabetes insipidus) despite a level at the upper
end of the therapeutic range. Lithium has a narrow therapeutic window, and side
, effects can occur even within the therapeutic range. Dose reduction is warranted
with close monitoring of mood stability and serum levels. NSAIDs, thiazide diuretics,
and ACE inhibitors can increase lithium levels by reducing renal clearance. While a
beta-blocker may help with tremor, it doesn't address the underlying toxicity
concern. Abrupt discontinuation risks mood destabilization.
5. A 19-year-old male with first-episode psychosis presents with delusions of
reference, hallucinations, disorganized speech, and negative symptoms. He
has no significant past medical history. Which antipsychotic would be most
appropriate to initiate?
A) Chlorpromazine
B) Haloperidol
C) Aripiprazole
D) Olanzapine
E) Clozapine
CORRECT ANSWER: C) Aripiprazole
Rationale: Second-generation (atypical) antipsychotics like aripiprazole are
preferred for first-episode psychosis due to superior efficacy in treating negative
symptoms and a lower risk of tardive dyskinesia compared to first-generation
agents. Aripiprazole has a favorable metabolic profile with minimal weight gain and
reduced risk of metabolic syndrome. Chlorpromazine and haloperidol (first-
generation) carry higher risks of extrapyramidal side effects and tardive dyskinesia.
Clozapine is reserved for treatment-resistant psychosis due to the need for regular
monitoring (agranulocytosis). Olanzapine, while effective, carries higher metabolic
risk.
6. A 35-year-old female with Major Depressive Disorder has tried three
different SSRIs without adequate response over the past 12 weeks at
therapeutic doses. What is the most evidence-based next step?
