Correct answer: B — Refer urgently for assessment of possible heparin-induced thrombocytopenia

HIT is associated with thrombosis despite thrombocytopenia and needs urgent assessment. 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.
