Domain 1: Major Depressive Disorder (MDD) &
Antidepressants
Q1. A 16-year-old female presents with depressed mood,
anhedonia, hypersomnia, and increased appetite. Her parents
report she has become increasingly irritable. What is the first-line
pharmacologic treatment?
A) Fluoxetine
B) Sertraline
C) Escitalopram
D) Bupropion
A1. A) Fluoxetine. *Rationale: Fluoxetine is the only SSRI FDA-
approved for pediatric MDD (ages 8+). While sertraline and
escitalopram are used off-label, fluoxetine has the strongest
evidence base for adolescents. Bupropion is contraindicated due
to seizure risk.*
Q2. A 72-year-old male with a history of coronary artery disease
presents with MDD. Which antidepressant requires an ECG
baseline due to QTc prolongation risk?
A) Citalopram
,B) Sertraline
C) Venlafaxine
D) Bupropion
A2. A) Citalopram. *Rationale: Citalopram is associated with
dose-dependent QTc prolongation. Maximum dose in older adults
is 20 mg/day. ECG monitoring is recommended, especially in
those with cardiac history or electrolyte abnormalities.*
Q3. A patient on phenelzine (MAOI) ingests a large amount of
aged cheddar cheese. They present with severe headache,
hypertension, and tachycardia. What is the priority intervention?
A) Administer phentolamine
B) Administer IV benzodiazepines
C) Induce vomiting
D) Administer labetalol
A3. A) Phentolamine. Rationale: This is a hypertensive crisis from
tyramine interaction. Phentolamine (non-selective alpha-blocker) is
specific for reducing blood pressure. Benzodiazepines help anxiety
but don't lower BP. Labetalol is avoided due to unopposed alpha
stimulation.
Q4. A patient on paroxetine for 6 months reports a 15-pound
weight gain, sexual dysfunction, and feeling "emotionally
blunted." You decide to switch antidepressants. Which strategy is
best to minimize discontinuation syndrome?
A) Abruptly stop paroxetine and start fluoxetine next day
B) Cross-taper: decrease paroxetine by 25% weekly while titrating
bupropion
C) Add bupropion to paroxetine without changing paroxetine
,dose
D) Stop paroxetine, wait 2 weeks, then start phenelzine
A4. B) Cross-taper. Rationale: Paroxetine has a short half-life and
high anticholinergic burden, causing severe discontinuation
syndrome. Cross-tapering minimizes symptoms. Bupropion can
augment sexual function but switching is the question focus.
Q5. A patient on venlafaxine 225 mg/day reports missed doses
over the weekend and now presents with "brain zaps," nausea,
and vertigo. What is venlafaxine withdrawal syndrome due to?
A) High histamine receptor blockade
B) Short half-life (5-11 hours) with abrupt drop in
serotonin/norepinephrine
C) Dopamine receptor upregulation
D) Cholinergic rebound
A5. B) Short half-life. *Rationale: Venlafaxine and paroxetine
have the shortest half-lives among antidepressants, leading to
rapid symptom onset (24-48 hours) after missed doses. "Brain
zaps" are characteristic.*
Domain 2: Bipolar Disorder & Mood Stabilizers
Q6. A 24-year-old male with bipolar I disorder is stabilized on
lithium 900 mg/day. Labs show: lithium level 0.8 mEq/L, creatinine
1.3 mg/dL (baseline 0.9), and TSH 6.2 mIU/mL. What is the most
appropriate next step?
A) Decrease lithium to 600 mg/day
, B) Add levothyroxine and monitor renal function
C) Switch to valproic acid immediately
D) Increase lithium to 1200 mg/day
A6. B) Add levothyroxine and monitor renal
function. *Rationale: Lithium causes subclinical (TSH 4-10) or
overt hypothyroidism. TSH >4.0 warrants levothyroxine. Creatinine
rise >0.5 from baseline or >1.5 requires dose reduction or switch,
but here change is mild; monitor.*
Q7. A patient with bipolar II disorder presents with rapid cycling
(4 episodes in past year). Which medication is LEAST likely to be
effective for prevention of rapid cycling?
A) Lamotrigine
B) Lithium
C) Valproate
D) Antidepressant monotherapy
A7. D) Antidepressant monotherapy. Rationale: Antidepressants
can destabilize rapid cycling bipolar disorder. Lamotrigine is
particularly effective for bipolar II and rapid cycling prevention.
Lithium and valproate are first-line.
Q8. A 30-year-old female with bipolar I disorder is pregnant (first
trimester) and seeks treatment options. Which mood stabilizer is
associated with the highest risk of neural tube defects?
A) Lithium
B) Lamotrigine
C) Valproic acid
D) Carbamazepine
