Correct answer: A — Advise urgent medical assessment and creatine kinase testing before continuing the statin

Muscle symptoms with dark urine raise concern about severe statin-associated muscle injury. 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.
