Section 1: Pharmacotherapeutics Across the Lifespan (Questions 1–25)
1. A 4-year-old child is prescribed amoxicillin for acute otitis media. What
is the recommended pediatric dosing?
A. 20 mg/kg/day divided BID
B. 80–90 mg/kg/day divided BID
C. 5 mg/kg/day once daily
D. 150 mg/kg/day divided TID
Answer: B. 80–90 mg/kg/day divided BID
Rationale: High-dose amoxicillin is first-line for AOM to overcome S.
pneumoniae resistance (AAP, 2025). Competency: Apply pediatric dosing
guidelines.
2. In a 72-year-old patient with hypertension, which antihypertensive is
most likely to cause orthostatic hypotension?
A. Amlodipine
, B. Lisinopril
C. Doxazosin
D. Hydrochlorothiazide
Answer: C. Doxazosin
Rationale: Alpha-1 blockers cause vasodilation, increasing fall risk in
geriatrics (Beers Criteria, 2025). Competency: Identify geriatric
pharmacotherapy risks.
3. A 30-year-old pregnant woman (first trimester) has a UTI. Which
antibiotic is safest (FDA Category B)?
A. Ciprofloxacin
B. Nitrofurantoin
C. Tetracycline
D. Trimethoprim-sulfamethoxazole
Answer: B. Nitrofurantoin
Rationale: Safe in early pregnancy; avoids fetal risks like cartilage damage
(tetracyclines) or folate antagonism (TMP-SMX). Competency: Manage
pharmacotherapy in pregnancy.
4. For an 8-year-old with ADHD, methylphenidate is prescribed. What is
the primary mechanism of action?
A. Dopamine and norepinephrine reuptake inhibition
B. Serotonin receptor agonism
C. GABA enhancement
D. Glutamate antagonism
Answer: A. Dopamine and norepinephrine reuptake inhibition
Rationale: Increases catecholamines in prefrontal cortex, improving
attention (AACAP, 2025). Competency: Understand pediatric
psychopharmacology.
5. In a 65-year-old with osteoarthritis, which medication is contraindicated
per Beers Criteria?
, A. Acetaminophen
B. Ibuprofen
C. Celecoxib
D. Indomethacin
Answer: D. Indomethacin
Rationale: High risk of GI bleeding and CNS effects in older adults.
Competency: Apply geriatric safety guidelines.
6. A 2-year-old with status asthmaticus receives albuterol. What is the
expected effect?
A. Reduced airway inflammation
B. Bronchodilation via beta-2 agonism
C. Mucociliary clearance enhancement
D. Leukotriene inhibition
Answer: B. Bronchodilation via beta-2 agonism
Rationale: Activates adenylate cyclase, relaxing bronchial smooth muscle
(GINA, 2025). Competency: Manage acute pediatric asthma.
7. A 45-year-old with type 2 diabetes is started on metformin. What is the
initial adult dose?
A. 500 mg BID
B. 1000 mg TID
C. 250 mg daily
D. 2000 mg daily
Answer: A. 500 mg BID
Rationale: Start low to minimize GI side effects; titrate to 2000 mg/day
(ADA, 2025). Competency: Initiate antidiabetic therapy.
8. In a 10-year-old with epilepsy, levetiracetam is chosen. Why is it
preferred in pediatrics?
A. Minimal drug interactions
B. Once-daily dosing
, C. Broad-spectrum antibiotic effect
D. Low cost
Answer: A. Minimal drug interactions
Rationale: Does not induce CYP450, reducing polypharmacy risks (AAN,
2025). Competency: Select pediatric anticonvulsants.
9. A 70-year-old with heart failure is on furosemide. What electrolyte
imbalance is most likely?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypermagnesemia
Answer: B. Hypokalemia
Rationale: Loop diuretics increase potassium excretion (ACC/AHA, 2025).
Competency: Monitor diuretic therapy.
10.A 6-month-old with RSV bronchiolitis is managed supportively. Why
are antibiotics avoided?
A. Viral etiology
B. High risk of anaphylaxis
C. Poor oral absorption
D. Lack of FDA approval
Answer: A. Viral etiology
Rationale: RSV is viral; antibiotics are ineffective unless bacterial
superinfection occurs (AAP, 2025). Competency: Avoid inappropriate
antimicrobial use.
11.A 50-year-old with depression is prescribed sertraline. What is the
starting dose?
A. 25 mg daily
B. 50 mg daily
C. 100 mg BID
