Final answer:
The correct answer is (b) "I will remove the patch at night and put on a new one in the morning." This indicates that the client understands the importance of having a medication-free period to prevent nitroglycerin tolerance.
Step-by-step explanation:
The subject of this question falls under Health, specifically focusing on the proper self-administration of transdermal medication, in this case, nitroglycerin. The grade level is College, as the scenario involves a nursing education context which aligns with college-level health studies. Answering the student's question, the correct statement that indicates an understanding of the nurse's teaching on how to self-administer transdermal medication is option (b): "I will remove the patch at night and put on a new one in the morning."
This reflects an understanding of the proper usage because it ensures that the client will have a medication-free period, which is often recommended to prevent tolerance to nitroglycerin. Rotating the application site to avoid skin irritation and applying to a clean, hairless area of skin is also advised, which rules out options (a) and (c). The client should not remove the patch if they experience chest pain; instead, they should follow their angina action plan, which might include using a fast-acting nitrate preparation, indicating that option (d) is incorrect.
