Which statement indicates that a client understands the proper use of transdermal patches?

The statement that indicates proper understanding of transdermal patch usage is that the client will clean and dry the area before applying the patch. This practice is crucial because applying a transdermal patch to clean, dry skin ensures optimal adhesion and promotes effective drug absorption. Moisture or oils on the skin can interfere with the adhesive properties of the patch and hinder the medication's ability to penetrate the skin and enter the systemic circulation.

Maintaining skin cleanliness helps to minimize the risk of irritation or infection at the application site. Additionally, a properly prepared skin surface allows for consistent drug delivery, which is essential for achieving the desired therapeutic effect over the duration of the patch's wear time. Using a clean and dry area is standard practice for applying transdermal patches and enhances the overall safety and efficacy of the treatment.
