1. Which medication is classified as a loop diuretic?
A) Furosemide
B) Hydrochlorothiazide
C) Spironolactone
D) Mannitol
Answer: A
Rationale: Furosemide is a loop diuretic that inhibits Na⁺ and Cl⁻ reabsorption in the
loop of Henle.
2. A common side effect of ACE inhibitors is:
A) Hypokalemia
B) Cough
C) Tachycardia
D) Constipation
Answer: B
Rationale: ACE inhibitors increase bradykinin, leading to a persistent dry cough.
3. Nursing consideration for nitroglycerin includes:
A) Store in a refrigerator
B) Avoid topical administration
C) Monitor BP due to hypotension risk
D) Give with grapefruit juice
Answer: C
Rationale: Nitroglycerin can cause hypotension and dizziness.
4. Beta-blockers primarily work by:
A) Increasing heart rate
B) Decreasing heart rate and contractility
C) Promoting vasoconstriction
D) Increasing cardiac output
Answer: B
Rationale: Beta-blockers reduce sympathetic stimulation to the heart.
5. Patient teaching for digoxin includes:
A) Monitor pulse; hold if <60 bpm
B) Increase sodium intake
C) Expect diuresis
D) Take only at night

Answer: A
Rationale: Digoxin slows heart rate; bradycardia may indicate toxicity.
6. A patient taking spironolactone should avoid:
A) Bananas
B) Bread
C) Cheese
D) Rice
Answer: A
Rationale: Spironolactone is potassium-sparing; avoid hyperkalemia.
7. Hydrochlorothiazide primarily treats:
A) Hypertension and edema
B) Heart failure only
C) Tachycardia
D) Hyperkalemia
Answer: A
Rationale: Thiazides reduce blood volume and vascular resistance.
8. Adverse effect of loop diuretics:
A) Hyperkalemia
B) Hypokalemia
C) Bradycardia
D) Hypoglycemia
Answer: B
Rationale: Loop diuretics cause potassium loss.
9. Patient teaching for amlodipine includes:
A) Change positions slowly
B) Avoid water intake
C) Take with caffeine
D) Skip doses if BP normal
Answer: A
Rationale: Amlodipine may cause dizziness due to hypotension.
10. Nitroglycerin is contraindicated in patients taking:
A) Beta-blockers
B) Sildenafil (Viagra)
C) ACE inhibitors
D) Diuretics
Answer: B
Rationale: Combination can cause severe hypotension.
11–20: Respiratory Drugs
11. Albuterol is classified as a:
