Correct answer: C — Sit down, use one spray under the tongue, repeat after five minutes if needed and seek emergency help if pain persists

GTN can cause hypotension and persistent pain may indicate acute coronary syndrome. 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.
