The duration of action for nitroglycerin typically ranges from 20 to 30 minutes, which reflects how long the drug remains effective in dilating blood vessels to relieve angina and improve blood flow to the heart. This moderate duration allows for effective management of acute episodes of chest pain while providing a balance in how often the medication may need to be administered. Understanding this duration is crucial for healthcare providers when considering dosing schedules and the timing of further interventions if symptoms persist.

Other durations mentioned in the choices either underestimate or overestimate the effect of nitroglycerin, which is why it's important to recognize the precise timeframe for optimal therapeutic outcomes. This knowledge aids in ensuring proper patient care and adherence to medication regimens.
