A nurse is teaching a client who has stable angina and a new prescription for nitroglycerin transdermal patches 0.8 mg/hr daily. Which of the following statements by the client indicates an understanding of the teaching?
“I can cut the patches in half to save money."
“I will apply a new patch to the same site whenever I replace it."
“I will take the patch off after dinner every night."
"I can put a second patch on if I have chest pain."
The Correct Answer is C
A. “I can cut the patches in half to save money": Cutting nitroglycerin patches is not recommended as it can alter the medication's release rate and efficacy. Therefore, this statement indicates a misunderstanding and should be corrected.
B. “I will apply a new patch to the same site whenever I replace it": Rotating patch sites is essential to prevent skin irritation and tolerance development. Therefore, this statement indicates a misunderstanding and should be corrected.
C. “I will take the patch off after dinner every night": This statement demonstrates understanding because nitroglycerin patches are typically worn for a certain number of hours (e.g., 12-14 hours) and then removed for a drug-free interval to prevent tolerance development.
D. "I can put a second patch on if I have chest pain": Applying multiple nitroglycerin patches simultaneously can lead to excessive vasodilation and hypotension, which can be dangerous. Therefore, this statement indicates a misunderstanding and should be corrected.
