Correct answer: B — Advise following the discharge plan and confirm renal function recovery before restarting metformin

Metformin may need withholding during AKI and restart depends on renal recovery. 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.
