Question 1 of 5
A nurse is teaching a group of nurses about the administration of nitroglycerin. Which of the following routes of administration has the most rapid onset for the client?
Correct Answer: B
Rationale: The correct answer is B: Sublingual. Nitroglycerin is rapidly absorbed through the mucous membranes under the tongue, bypassing the first-pass metabolism in the liver, leading to a quick onset of action within 1-3 minutes.
Topical ointment (
A) has a slower onset as it requires absorption through the skin. Transdermal patch (
C) delivers nitroglycerin slowly over 24 hours, not providing rapid onset. Sustained-release (
D) formulations release the medication gradually over time, resulting in a delayed onset compared to sublingual administration.
