What is the proper route for administering nitroglycerin?

The correct option for the proper route for administering nitroglycerin is sublingual. This method allows for rapid absorption of the medication into the bloodstream through the tissues under the tongue. Nitroglycerin is primarily used to relieve angina episodes or chest pain caused by inadequate blood flow to the heart.

When administered sublingually, the onset of action is quick, typically within a few minutes, making it an effective option for acute relief. This route bypasses the digestive system and first-pass metabolism in the liver, which can significantly reduce the drug's effectiveness if taken orally.

Intravenous administration is commonly used in more acute settings or for patients requiring constant infusion for pain management, but it is not the primary route for quick relief of angina. Oral administration, while possible, has a delayed onset and is not ideal for immediate relief in acute situations. Topical forms of nitroglycerin, such as patches or ointments, provide prolonged effects and are used for ongoing management of angina rather than immediate relief.

Understanding the sublingual route is essential for effective and timely management of patients experiencing chest pain, emphasizing both the speed and efficiency of absorbing nitroglycerin through this method.
