QUESTION 1
A 34-year-old patient with major depressive disorder has been on sertraline
100 mg daily for 8 weeks with minimal response. Which intervention is most
appropriate at this time?
A) Increase sertraline to 200 mg daily and reassess in 2 weeks
B) Add bupropion 150 mg daily to the current sertraline regimen
C) Discontinue sertraline and switch to fluoxetine 40 mg daily
D) Add augmentation therapy with aripiprazole 2-5 mg daily
E) Recommend psychotherapy only and discontinue medication
, CORRECT ANSWER: D) Add augmentation therapy with aripiprazole 2-5 mg
daily
RATIONALE: After 8 weeks of adequate dosing with SSRI monotherapy, the patient
meets criteria for treatment-resistant depression. Augmentation with an atypical
antipsychotic, particularly aripiprazole, is an evidence-based strategy supported by
research and clinical guidelines. Aripiprazole at 2-5 mg daily can enhance
serotonergic activity and is FDA-approved for this indication. Increasing the same
medication further or switching SSRIs without optimization is less effective than
augmentation. Combining SSRIs directly without augmentation assessment is
premature.

QUESTION 2
A 28-year-old female with bipolar I disorder is prescribed lithium carbonate.
Which laboratory value must be monitored most closely during the first week
of therapy?
A) Thyroid-stimulating hormone (TSH) levels
B) Serum creatinine and blood urea nitrogen (BUN)
C) Serum lithium concentration
D) Complete blood count (CBC)
E) Liver function tests (LFTs)
CORRECT ANSWER: C) Serum lithium concentration
RATIONALE: Lithium has a narrow therapeutic window (0.6-1.2 mEq/L), and serum
lithium levels must be monitored regularly, with the first level typically drawn 5
days after initiation or dose changes. This ensures therapeutic efficacy while
preventing toxicity. While TSH, renal function, and other labs are important baseline
and periodic monitoring (especially TSH for hypothyroidism and renal function
,given lithium's nephrotoxic potential), serum lithium concentration is the priority
during initial therapy establishment to ensure proper dosing and safety.

QUESTION 3
A 45-year-old male with schizophrenia presents with acute dystonia after
receiving haloperidol 10 mg IM in the emergency department. Which
medication would be administered immediately?
A) Diphenhydramine 25-50 mg IV/IM
B) Propranolol 20 mg PO
C) Flumazenil 0.2 mg IV
D) Lorazepam 2 mg IV
E) Benztropine 0.5 mg PO
CORRECT ANSWER: A) Diphenhydramine 25-50 mg IV/IM
RATIONALE: Acute dystonia is an extrapyramidal side effect requiring immediate
intervention with an anticholinergic agent. Diphenhydramine is rapidly effective
when given intravenously or intramuscularly, providing relief within minutes. While
benztropine is also anticholinergic and effective, the IV/IM route of
diphenhydramine provides faster symptom resolution in acute dystonic reactions.
Propranolol treats akathisia, flumazenil reverses benzodiazepines, and lorazepam
addresses acute agitation but not dystonia specifically. The route and speed of
action make diphenhydramine the preferred choice.

QUESTION 4
, A 52-year-old patient with generalized anxiety disorder reports experiencing
palpitations, diaphoresis, and tremor. Which medication is most appropriate
for PRN use?
A) Buspirone 15 mg three times daily
B) Alprazolam 0.25-0.5 mg every 4-6 hours
C) Sertraline 50 mg daily
D) Hydroxyzine 25-50 mg three times daily
E) Propranolol 10 mg daily
CORRECT ANSWER: B) Alprazolam 0.25-0.5 mg every 4-6 hours
RATIONALE: Benzodiazepines are the gold standard for PRN acute anxiety
management due to rapid onset of action (15-30 minutes). Alprazolam at 0.25-0.5
mg every 4-6 hours provides quick symptom relief for acute physical manifestations
like palpitations, diaphoresis, and tremor. Buspiron is a non-addictive alternative
but works over days, not minutes. SSRIs require weeks for efficacy. Hydroxyzine has
delayed onset compared to benzodiazepines. Propranolol addresses somatic
symptoms but not the anxiety itself. For PRN use in acute anxiety episodes,
benzodiazepines are most appropriate, though long-term use should be avoided
due to dependency risks.

QUESTION 5
A 19-year-old college student presents with depressed mood, anhedonia,
sleep disturbance, and suicidal ideation for 2 weeks following romantic
rejection. What is the primary diagnostic consideration?
A) Persistent Depressive Disorder (Dysthymia)
B) Major Depressive Disorder, Single Episode
C) Adjustment Disorder with Depressed Mood
