A nurse administers subcutaneous NPH insulin at 0700 to a child who has diabetes.

At which of the following times should the nurse observe for hypoglycemia caused by the onset of the medication?

A.

0715.

B.

0800.

C.

0900.

D.

1000.

Answer and Explanation

The Correct Answer is B

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 A

Explanation

A nurse should never share her password for access to the facility’s computer system with anyone.
Sharing passwords can compromise the security and confidentiality of patient information.
For the second question you asked, the correct answer is choice A.
“I’ll use my electric razor for shaving.” This statement indicates that the client understands that warfarin (coumadin) can increase the risk of bleeding and that using an electric razor can help reduce the risk of cuts and bleeding while shaving.
Choice B is not the best answer because taking aspirin while on warfarin (coumadin) can increase the risk of bleeding.
Choice C is not the best answer because eating foods high in vitamin K can interfere with the effectiveness of warfarin (Coumadin).
Choice D is not the best answer because drinking alcohol while on warfarin (coumadin) can increase the risk of bleeding.

Correct Answer is B

Explanation

Step 1: Calculate the total infusion time in minutes.

24 hours × (60 minutes/hour) = 1440 minutes.

Step 2: Calculate the infusion rate in mL/min.

1200 mL ÷ 1440 minutes = 0.833 mL/min.

Step 3: Calculate the drop rate in gtt/min.

0.833 mL/min × 15 gtt/mL = 12.495 gtt/min.

Step 4: Round to the nearest whole number.

12.495 ≈ 13 gtt/min.

Answer: 13 gtt/min.
