Question

a nurse is reinforcing teaching about nitroglycerin transdermal patches with a client who has a history of angina. which of the following statements by the client indicates understanding of the instructions?

• \if i experience angina, i should apply a second patch.\
• \i will take my patch off every evening just before going to bed.\
• \i will call the doctor if i develop headaches during treatment.\
• \i can drink up to five beers a day while im on this medication.\

Explanation:

• For the first option: Nitroglycerin transdermal patches are for prophylaxis; angina attacks are treated with sublingual nitroglycerin, not an additional patch. So this is incorrect.
• For the second option: Nitroglycerin patches are often removed at night (e.g., 12 - 14 hours off) to prevent tolerance, so taking it off in the evening is correct.
• For the third option: Headaches are a common side effect of nitroglycerin and usually subside, so calling the doctor for headaches is unnecessary. Incorrect.
• For the fourth option: Alcohol and nitroglycerin can cause severe hypotension, so drinking beer is contraindicated. Incorrect.

Answer:

B. "I will take my patch off every evening just before going to bed."
