A nurse is reinforcing teaching for a client who has angina pectoris and a new prescription to apply a nitroglycerin transdermal patch daily.
Which of the following instructions should the nurse give the client?
Use an old patch with medication residue on the inside and discard it in a closed receptacle.
Keep a nitroglycerin patch in place for 72 hours before replacing.
Apply the patch to a hairy area of the skin for better adherence.
Cleanse the skin before applying a nitroglycerin patch.
The Correct Answer is D
The nurse should instruct the client to cleanse the skin before applying a nitroglycerin transdermal patch 1.
This is because it is important to apply the patch to a clean, dry skin area with little or no hair that is free of scars, cuts, or irritation 1.
Choice A is incorrect because it is not recommended to use an old patch with medication residue.
Instead, always remove a previous patch before applying a new one 1.
Choice B is incorrect because a nitroglycerin patch should not be kept in place for 72 hours before replacing.
Instead, it should be worn for 12 to 14 hours and then removed 2.
Choice C is incorrect because the patch should not be applied to a hairy area of the skin for better adherence.
Instead, it should be applied to an area with little or no hair 1.

Correct Answer is B
Explanation
NPH insulin has an onset of action of about 1 to 2 hours, peaks in 4 to 12 hours, and lasts up to 24 hours. Given the administration at 0700, the onset of action would typically occur between 0800 and 0900. Hypoglycemia is most likely to occur during the onset or peak periods due to the insulin's glucose-lowering effect.
Among the options:
- A. 0715: Too early, as NPH insulin's onset is not within 15 minutes.
- B. 0800: Within the onset window (1 hour after administration), making it a plausible time to observe for hypoglycemia.
- C. 0900: Also within the onset window (2 hours after administration), another reasonable time to monitor.
- D. 1000: Slightly beyond the typical onset but still early in the action profile, where hypoglycemia could occur if glucose levels drop.
Since the question asks for the time to observe for hypoglycemia caused by the onset, the earliest time within the onset window is most appropriate. Thus, B. 0800 is the best answer, as it aligns with the start of NPH insulin’s onset period.
Final Answer: B. 0800
Correct Answer is B
Explanation
The nurse should administer 2 tablets.
Since each tablet contains 325 mg of aspirin, to administer a dose of 650 mg, the nurse should give 650 mg / 325 mg/tablet = 2 tablets.
Choice A is incorrect because 1 tablet would only provide a dose of 325 mg.
Choice C is incorrect because 3 tablets would provide a dose of 975 mg.
Choice D is incorrect because 4 tablets would provide a dose of 1300 mg.
