Final answer:
a. "While using the patch, I will be careful when rising from a chair."
The correct statement that indicates an understanding of nitroglycerin patch teaching is being careful when rising from a chair due to the risk of dizziness from vasodilation and blood pressure changes. The patch should not be worn continuously for 24 hours, applied to the same location each time, or used in response to acute chest pain.
Step-by-step explanation:
A nurse is reinforcing teaching with a client who is to start therapy with a nitroglycerin transdermal patch. Which of the following statements by the client indicates an understanding of the teaching?
The correct answer is: a. "While using the patch, I will be careful when rising from a chair." This statement indicates an understanding that nitroglycerin can cause vasodilation, leading to lowered blood pressure, which can result in dizziness upon sudden position changes. Thus, the client should be cautious when rising to prevent falling from a drop in blood pressure.
Option b is incorrect because the patch is typically worn for 12-14 hours and then removed to allow a nitrate-free period to prevent tolerance to nitroglycerin. Option c is not advisable as applying the patch to the same location each time can lead to skin irritation. Lastly, option d is incorrect because the nitroglycerin patch is used for angina prevention, not for acute chest pain relief; for immediate relief, sublingual nitroglycerin would be used instead.
