A. Lisinopril
B. Atenolol
C. Amlodipine
D. Furosemide
Answer: B. Atenolol
Rationale: Atenolol is a beta-blocker that works by blocking beta-adrenergic receptors, reducing
heart rate and blood pressure. Lisinopril is an ACE inhibitor, amlodipine is a calcium channel
blocker, and furosemide is a diuretic.
2. The primary therapeutic effect of metformin is:
A. Increase insulin production
B. Decrease glucose production by the liver
C. Enhance glucose absorption in the intestines
D. Stimulate glucagon release
Answer: B. Decrease glucose production by the liver
Rationale: Metformin works by decreasing hepatic glucose production and improving insulin
sensitivity. It does not stimulate insulin production or enhance glucose absorption.
3. Which of the following is a common side effect of opioids?
A. Hyperkalemia
B. Tachycardia
C. Constipation
D. Diarrhea
Answer: C. Constipation
Rationale: Opioids commonly cause constipation as a side effect due to their action on the

4. A client is prescribed warfarin. The nurse should monitor the client's:
,A. Blood glucose levels
B. INR (International Normalized Ratio)
C. Liver enzymes
D. Potassium levels
Answer: B. INR (International Normalized Ratio)
Rationale: Warfarin is an anticoagulant, and its effectiveness is monitored using the INR. This
helps ensure the blood does not become too thick (leading to clotting) or too thin (leading to
bleeding).
5. Which of the following would the nurse expect in a patient with an overdose of

if administered too quickly?
A. Vancomycin
B. Amoxicillin
