Pharmacology | Actual Q&A with Rationale (NURS
6512 Exam 2) | Walden
Section A: Multiple Choice (40 questions)
Q1. Which antihypertensive drug class directly inhibits the conversion of angiotensin I
to angiotensin II?
A. Angiotensin II receptor blockers (ARBs)
B. Beta-blockers
C. ACE inhibitors ✅
D. Calcium channel blockers
Rationale: ACE inhibitors block the enzyme that converts angiotensin I to angiotensin II.
Q2. Which thiazide diuretic is most commonly used for hypertension?
A. Furosemide
B. Spironolactone
C. Hydrochlorothiazide ✅
D. Mannitol
Rationale: HCTZ is a first-line thiazide for hypertension.
Q3. A patient on a loop diuretic like furosemide is at highest risk for which electrolyte
,disturbance?
A. Hyperkalemia
B. Hypokalemia ✅
C. Hypercalcemia
D. Hypermagnesemia
Rationale: Loop diuretics increase potassium excretion.
Q4. Which antiarrhythmic drug is classified as a sodium channel blocker (Class I)?
A. Amiodarone
B. Lidocaine ✅
C. Sotalol
D. Verapamil
Rationale: Lidocaine is a Class IB sodium channel blocker.
Q5. Which beta-blocker is cardioselective?
A. Propranolol
B. Metoprolol ✅
C. Carvedilol
D. Labetalol
, Rationale: Metoprolol primarily blocks β1 receptors.
Q6. The most common adverse effect of ACE inhibitors is:
A. Hyperkalemia
B. Dry cough ✅
C. Bradycardia
D. Bronchospasm
Rationale: ACE inhibitor-induced cough is due to bradykinin accumulation.
Q7. Which calcium channel blocker is most likely to cause constipation?
A. Nifedipine
B. Amlodipine
C. Verapamil ✅
D. Diltiazem
Rationale: Verapamil has stronger effect on GI smooth muscle, causing constipation.
Q8. Spironolactone is a potassium-sparing diuretic that acts by:
A. Blocking the Na-K-Cl cotransporter
B. Antagonizing aldosterone receptors ✅
C. Inhibiting carbonic anhydrase
D. Increasing osmotic diuresis
