Correct answer: A — Use one or two sprays while sitting down and seek emergency help if pain persists after repeat use

GTN should be used with the patient seated because it can cause hypotension. Persistent chest pain after appropriate GTN use may represent acute coronary syndrome. In this vignette, "Use one or two sprays while sitting down and seek emergency help if pain persists after repeat use" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
