How will the nurse administer a nitroglycerin sublingual tablet to the patient?

The correct answer is D: Place the tablet under the patient's tongue. Nitroglycerin sublingual tablets are designed to be absorbed quickly through the mucous membrane under the tongue into the bloodstream, providing rapid relief for chest pain or angina. Placing the tablet next to the cheek (A) or having the patient swallow it (B) would not allow for the medication to be absorbed effectively. Crushing and dissolving the tablet in water (C) would alter its intended route of administration and potentially decrease its effectiveness. Therefore, placing the tablet under the tongue (D) is the correct and most appropriate method for administering nitroglycerin sublingual tablets.
