NCLEX Pharmacology Quiz Bank – 150 Questions (With Answers &
Rationales)
NCLEX- Revision multiple choice questions.
1. (ACE Inhibitors) A patient taking lisinopril reports a persistent cough. What is the most
likely cause?
A. Bradykinin accumulation
B. Sodium retention
C. Hypoglycemia
D. Increased insulin secretion
Answer: A
Rationale: ACE inhibitors increase bradykinin levels which can cause a persistent dry cough.
2. (Beta Blockers) What is the primary therapeutic effect of propranolol in hypertension?
A. Increase heart rate
B. Decrease heart rate and cardiac output
C. Increase sodium retention
D. Dilate renal arteries
Answer: B
Rationale: Beta blockers decrease heart rate and cardiac output, reducing blood pressure.
3. (Diuretics) A patient taking furosemide should be monitored for which electrolyte
imbalance?
A. Hypercalcemia
B. Hypernatremia
C. Hypokalemia
,D. Hypermagnesemia
Answer: C
Rationale: Loop diuretics like furosemide increase potassium loss in urine leading to
hypokalemia.
4. (Insulin) Which symptom indicates hypoglycemia in a diabetic patient receiving insulin?
A. Sweating and tremors
B. Dry skin
C. Excessive thirst
D. Slow respirations
Answer: A
Rationale: Sweating, tremors, and confusion are early symptoms of hypoglycemia.
5. (Anticoagulants) Which laboratory value is used to monitor warfarin therapy?
A. Platelet count
B. Creatinine
C. INR
D. Blood glucose
Answer: C
Rationale: INR measures blood clotting time and is used to monitor warfarin therapy.
