A nurse is reinforcing teaching with a group of nurses about the administration of nitroglycerin. Which of the following routes of administration provides the most rapid onset for the client?
A.
Suspended release
B.
Transdermal patch
C.
Topical ointment
D.
Sublingual
The correct answer and Explanation is :
The correct answer is D. Sublingual.
Explanation:
The sublingual route of administration provides the most rapid onset of action because the medication is absorbed directly into the bloodstream through the tissues under the tongue. This bypasses the digestive system and liver metabolism (first-pass effect), leading to quicker absorption and faster relief, typically within 1-5 minutes.
- Suspended release (A) is designed to release the medication slowly over time, providing a delayed onset.
- Transdermal patch (B) releases the medication gradually through the skin, offering a slower onset but prolonged effect.
- Topical ointment (C) also provides a slower, sustained release as it is absorbed through the skin.
Sublingual nitroglycerin is commonly used in acute situations like angina attacks where rapid relief is critical.
