Correct answer: D — Query the prescription because nitrofurantoin may be unsuitable at this renal function

Nitrofurantoin needs adequate renal function for urinary efficacy and safety. In this scenario, the pharmacist should prioritise safe supply, appropriate counselling and timely referral or clarification where needed. This is the single best answer because the other options would either delay assessment, ignore a clinically significant risk, or create an unsafe legal or professional outcome.
