What statement indicates a need for further teaching regarding the nitroglycerin transdermal patch?

The statement indicating a need for further teaching regarding the nitroglycerin transdermal patch is that the individual will apply the patch for 24 hours then replace it. This indicates a misunderstanding of how the patch should be used.

Nitroglycerin transdermal patches are typically designed to be worn for a specific duration, usually about 12 to 14 hours a day, followed by a patch-free interval to prevent tolerance to the medication. Wearing the patch continuously for 24 hours may lead to increased side effects, reduced effectiveness, and a greater risk of developing tolerance to nitroglycerin.

In contrast, the other statements reflect proper use of the nitroglycerin transdermal patch. Rotating the patch location prevents skin irritation, cleaning the area where the patch was applied ensures that the skin is free of residue and can promote better adherence and effectiveness, and being cautious about showering while wearing the patch acknowledges the importance of keeping the patch intact and reducing exposure to water, which could affect its adhesion or absorption.
