Correct answer: E — Sit down, use one dose, and seek urgent help if pain persists

GTN can cause hypotension and dizziness, so the patient should sit before use. Persistent chest pain despite appropriate GTN dosing requires urgent assessment. In this scenario, the correct option is sit down, use one dose, and seek urgent help if pain persists. The other options are plausible but do not address the key clinical, legal or safety issue as directly. This aligns with UK pharmacy practice guidance cited in the reference field.
