Correct answer: B — Use one or two sprays under the tongue while resting, then seek emergency help if pain persists

GTN spray is used sublingually at the onset of angina symptoms or before a known trigger. The patient should sit or rest because dizziness and hypotension can occur. If chest pain does not settle promptly after appropriate GTN use, emergency help is needed because acute coronary syndrome must be considered. It is not designed to be swallowed or applied topically.
