The most appropriate method for assisting a patient with a prescribed nitroglycerin under non-acute conditions?

• A. Swallow the tablet whole with water.
• B. Place tablet under tongue and allow it to dissolve.
• C. Apply as topical patch.
• D. Inhale the spray.

Answer: (B)

The key idea is rapid, sublingual absorption. Placing the nitroglycerin tablet under the tongue and letting it dissolve allows the drug to enter the bloodstream quickly through the mucous membranes, producing fast relief from chest pain. Swallowing the tablet would send much of the medicine to the stomach and liver (first-pass metabolism), delaying or reducing its effect. A topical patch, by contrast, provides a slower, ongoing effect for prevention, not immediate relief. The spray is intended to be used sublingually, not inhaled into the lungs, so inhaling the spray wouldn’t deliver the medicine correctly. If symptoms persist or worsen, follow EMS guidelines and seek further care.
