What is a key nursing consideration when administering nitroglycerin?

When administering nitroglycerin, a crucial nursing consideration is to monitor blood pressure for hypotension. Nitroglycerin is a vasodilator that can lead to decreased blood pressure as it relaxes and widens the blood vessels, improving blood flow. This action can result in a significant drop in blood pressure, especially if the patient is also taking other antihypertensive medications or if they are dehydrated. Monitoring blood pressure ensures that any significant decreases can be addressed promptly, preventing complications such as dizziness, fainting, or falls.

Additionally, nitroglycerin does not need to be crushed for effective absorption; in fact, it is often given in forms such as sublingual tablets or patches designed for absorption through the oral mucosa. It can also be administered at night and does not have restrictions regarding food intake, making these options less relevant when considering the essential aspects of nitroglycerin administration.
