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?
Topical ointment
Sublingual
Transdermal patch
Sustained-release
The Correct Answer is B
A. Topical ointment has a slower onset as it must be absorbed through the skin before it can exert its effects.
B. Sublingual nitroglycerin provides rapid relief of angina symptoms because it is absorbed quickly into the bloodstream through the mucous membranes in the mouth, allowing for an immediate effect.
C. Transdermal patches release nitroglycerin slowly over time, leading to a delayed onset of action.
D. Sustained-release formulations are designed for prolonged effects rather than rapid onset, making them slower to take effect compared to sublingual administration.

Correct Answer is C
Explanation

B. Weight gain can occur with some antidepressants, but it is not a direct indicator of their effectiveness.
C. An increase in mood is a primary goal of treatment with sertraline, and reporting this improvement suggests that the medication is having a positive effect.
