1. Which of the following is a primary mechanism of action of ACE inhibitors?
A. Block beta-adrenergic receptors
B. Inhibit angiotensin-converting enzyme
C. Promote sodium retention
D. Increase sympathetic activity
Answer: B
Rationale: ACE inhibitors block the conversion of angiotensin I to angiotensin II, reducing
vasoconstriction and aldosterone secretion.
2. A patient taking warfarin is advised to avoid which vitamin-rich diet?
A. Vitamin C
B. Vitamin D
C. Vitamin K
D. Vitamin B12
Answer: C
Rationale: Vitamin K antagonizes warfarin’s effect by promoting clotting factor synthesis, which can
reduce anticoagulation.
3. Which class of drugs is first-line for heart failure with reduced ejection fraction?
A. Beta-blockers
, B. Calcium channel blockers
C. ACE inhibitors
D. Thiazide diuretics
Answer: C
Rationale: ACE inhibitors reduce afterload and improve survival in HFrEF patients.
4. Digoxin toxicity is more likely in patients with:
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypocalcemia
Answer: B
Rationale: Low potassium levels enhance digoxin binding to Na+/K+ ATPase, increasing toxicity risk.
5. Which opioid receptor is primarily responsible for analgesia?
A. Delta
B. Kappa
C. Mu
D. Sigma
Answer: C
Rationale: Mu receptors mediate analgesia, euphoria, and respiratory depression.
6. A patient receiving heparin requires monitoring of:
A. INR
B. aPTT
C. Platelet count only
D. Serum creatinine
Answer: B
Rationale: Heparin prolongs activated partial thromboplastin time (aPTT) and requires monitoring to
ensure therapeutic anticoagulation.
7. Which of the following drugs is an anticholinergic used for COPD?
A. Albuterol
B. Ipratropium
C. Montelukast
D. Theophylline
Answer: B
, Rationale: Ipratropium blocks muscarinic receptors in the airway, reducing bronchoconstriction.
8. Statins primarily lower cholesterol by:
A. Increasing intestinal absorption
B. Inhibiting HMG-CoA reductase
C. Activating lipoprotein lipase
D. Binding bile acids in the gut
Answer: B
Rationale: HMG-CoA reductase inhibition decreases cholesterol synthesis and upregulates LDL
receptors.
9. Which class of drugs is associated with QT prolongation?
A. Macrolide antibiotics
B. ACE inhibitors
C. Loop diuretics
D. NSAIDs
Answer: A
Rationale: Macrolides (e.g., azithromycin) can prolong ventricular repolarization, increasing
arrhythmia risk.
10.Which insulin has the fastest onset of action?
A. NPH
B. Regular
C. Lispro
D. Glargine
Answer: C
Rationale: Rapid-acting insulin analogs like lispro act within 15 minutes, ideal for mealtime coverage.
11.A patient with asthma is prescribed montelukast. What is its mechanism?
A. Beta-2 agonist
B. Leukotriene receptor antagonist
C. Corticosteroid receptor agonist
D. Anticholinergic
Answer: B
Rationale: Montelukast blocks leukotriene receptors, reducing airway inflammation and
bronchoconstriction.
