Correct answer: D — Avoid metoclopramide and seek advice about a suitable anti-emetic such as domperidone if appropriate

Dopamine antagonist antiemetics can worsen Parkinsonism and require careful selection. 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.
