1. A nurse administers morphine to a postoperative patient.
Which effect should the nurse monitor most closely?
A. Hypertension
B. Tachycardia

D. Diarrhea
Correct Answer: C
Rationale: Opioids such as morphine depress the respiratory
center in the brain, making respiratory depression the most
serious and potentially life-threatening adverse effect.
2. Which drug classification is used to lower cholesterol levels
by inhibiting HMG-CoA reductase?
A. Beta blockers
B. Statins
C. ACE inhibitors
D. Calcium channel blockers
,Correct Answer: B
Rationale: Statins inhibit HMG-CoA reductase, an enzyme
necessary for cholesterol synthesis in the liver.
3. The nurse is teaching a patient about warfarin therapy.

A. “I can take aspirin for pain.”
B. “I will eat more green leafy vegetables.”
C. “I need regular blood tests.”
