Final Answer:
The nurse should instruct the client to place the nitroglycerin transdermal patch on a different site for each application (Option D). This practice helps prevent tolerance and skin irritation, ensuring optimal therapeutic effectiveness.Thus,the correct option is D. Place the patch on a different site for each application
Step-by-step explanation:
Nitroglycerin transdermal patches are commonly used to manage angina by providing a continuous release of nitroglycerin, which helps dilate blood vessels and improve blood flow to the heart. It is crucial to rotate the application site with each new patch to prevent skin irritation and tolerance development.
Over time, the body can become accustomed to the medication if it is consistently applied to the same site, reducing its effectiveness. By changing the application site, the nurse ensures optimal absorption and therapeutic benefit.
Furthermore, leaving each patch in place for 24 hours is not recommended due to the development of tolerance. Nitroglycerin patches are typically worn for 12 to 14 hours, allowing for a patch-free interval to prevent tolerance. Applying another patch if experiencing chest pain is not advisable without consulting a healthcare provider, as it may lead to excessive nitrate exposure and adverse effects.
Covering the patch with a dry dressing is unnecessary unless there is a specific reason, such as skin irritation or the patch not adhering properly. In general, transdermal patches should be applied directly to clean, dry skin without covering them to facilitate drug absorption.
In summary, instructing the client to place the nitroglycerin patch on a different site for each application ensures the effectiveness of the therapy by preventing tolerance and skin irritation. This guidance aligns with best practices for the use of nitroglycerin transdermal patches in managing angina.
Therefore,the correct option is D. Place the patch on a different site for each application
