“I will take the patch off after dinner every night."

D.

"I can put a second patch on if I have chest pain."

Answer and Explanation

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.
