Questions & Verified Answers
1. Which of the following describes the mechanism of action of SGLT2 inhibitors like
empagliflozin?
A. Inhibiting the enzyme dipeptidyl peptidase-4 (DPP-4)
B. Increasing insulin secretion from pancreatic beta cells
C. Activating PPAR-gamma receptors in adipose tissue
D. Reducing glucose reabsorption in the proximal renal tubule
Answer: D
Rationale: SGLT2 inhibitors lower blood glucose by preventing the kidneys from reabsorbing glucose,
leading to its excretion in urine. Clear understanding of this concept improves both test performance
and everyday clinical judgment. Practice applying it to short case scenarios to lock the idea in place.
Remembering this point will help you decide the best nursing action when similar questions appear on
the exam. Link the answer to the client’s current condition and risk level.
2. When initiating levothyroxine therapy for a 75-year-old patient with a history of coronary
artery disease, what is the recommended starting dose?
A. 1.6 mcg/kg/day
B. 100 mcg daily
C. 50 to 75 mcg daily
D. 12.5 to 25 mcg daily
Answer: D
Rationale: In elderly patients or those with cardiac disease, levothyroxine should be started at a low
dose (12.5-25 mcg) to avoid stress on the heart. This knowledge supports safe care and helps the
nurse teach the client and family clearly and simply. Clear teaching improves cooperation and reduces
anxiety. Clear understanding of this concept improves both test performance and everyday clinical
judgment. Practice applying it to short case scenarios to lock the idea in place.

3. Which medication is the preferred treatment for hyperthyroidism during the first trimester
of pregnancy?
A. Methimazole
B. Levothyroxine
C. Radioactive Iodine
D. Propylthiouracil (PTU)
Answer: D
Rationale: PTU is preferred in the first trimester because methimazole is associated with birth defects
(aplasia cutis). Methimazole is typically used in the second and third trimesters. Understanding this
helps the nurse notice early warning signs and act before the problem gets worse. Early action often
prevents bigger complications for the client. Knowing the reason behind the correct answer makes it
easier to rule out the wrong options quickly. Look for the choice that protects the client and matches
the priority need.
4. A patient taking metformin is scheduled for a CT scan with intravenous contrast. What is
the appropriate management?
A. Continue metformin as usual
B. Hold metformin at the time of the procedure and restart 48 hours later if renal function is stable
C. Discontinue metformin 48 hours before and after the procedure
D. Double the dose for two days after the procedure
Answer: B
Rationale: Metformin should be withheld before contrast procedures and restarted only after checking
that serum creatinine is normal 48 hours later to prevent lactic acidosis. In practice, this guides the
nurse to set priorities and protect the client from harm. Safety, nutrition, and clear communication are
frequent priorities. Exam questions often test whether you can pick the most practical and safe choice
for the client in real situations. Focus on what the nurse can actually do right now.
