Questions & Verified Answers
1. A patient with Type 2 Diabetes has a serum creatinine of 1.6 mg/dL and a calculated GFR
of 35 mL/min/1.73m². What is the appropriate management regarding their Metformin
therapy?
A. Continue the current dose but monitor GFR monthly
B. Discontinue Metformin immediately as it is contraindicated below a GFR of 45
C. Reduce the dose by 50% and do not exceed 1000 mg/day
D. Switch to a Sulfonylurea as a first-line alternative
Answer: C
Rationale: Metformin is contraindicated when GFR is below 30 mL/min. If the GFR is between 30 and
45 mL/min, the dose should be reduced by 50% or a maximum of 1000mg/day, and initiation is not
recommended in this range. 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.
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.
2. Which class of diabetic medications is most likely to increase the risk of genitourinary
infections and, rarely, Fournier’s gangrene?
A. SGLT2 Inhibitors
B. DPP-4 Inhibitors
C. GLP-1 Receptor Agonists
D. Thiazolidinediones
Answer: A
Rationale: SGLT2 inhibitors work by promoting glycosuria, which provides a substrate for bacterial
and fungal growth in the urinary tract, increasing the risk of UTIs and necrotizing fasciitis of the
perineum. This knowledge supports safe care and helps the nurse teach the client and family clearly
and simply. Clear teaching improves cooperation and reduces anxiety. This is important because the
nurse must choose the action that keeps the client safest while still meeting their basic needs. Always
think about safety first when answering these questions.

3. When initiating Levothyroxine for a 78-year-old patient with a history of coronary artery
disease, what is the recommended starting dose?
A. 1.6 mcg/kg/day
B. 50 to 75 mcg/day
C. 12.5 to 25 mcg/day
D. 100 mcg/day
Answer: C
Rationale: In elderly patients or those with cardiac disease, the rule is ‘start low and go slow’ (12.5-25
mcg) to avoid precipitating myocardial ischemia or arrhythmias. 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. Understanding this helps the nurse notice early warning signs and act

4. A patient taking Methimazole for Graves’ disease presents with a sudden fever and sore
throat. What is the priority nursing/provider action?
A. Advise the patient to take acetaminophen and rest
B. Order a TSH and Free T4 level immediately
C. Reassure the patient that these are common side effects of the medication
D. Obtain a CBC with differential to check for agranulocytosis
Answer: D
Rationale: Agranulocytosis is a rare but life-threatening side effect of thionamides (Methimazole/PTU).
Fever and sore throat are early clinical signs that require immediate CBC monitoring. 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. 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.
