Correct answer: B — Use one or two sprays under the tongue and seek urgent help if pain persists after repeated doses

GTN spray is used sublingually at the onset of angina. Patients should sit down because headache, flushing or dizziness may occur. Persistent chest pain despite repeat GTN should prompt urgent medical assessment, and nitrates must not be combined with PDE5 inhibitors such as sildenafil.
