Correct answer: D — Sit down, use one or two sprays under the tongue, and seek emergency help if pain persists

GTN spray is used sublingually for acute angina symptoms and can cause dizziness or hypotension, so the patient should sit down. If pain does not resolve after appropriate repeated dosing within the advised timeframe, emergency help is needed. Swallowing, topical application, or delaying use would reduce effectiveness.
