A nurse is caring for a patient with diabetes mellitus who is prescribed regular insulin via a sliding scale. After administering the correct dose at 0715, by which of the following times should the nurse ensure the patient receives breakfast?

0720.

0815.

0745.

0730.

Answer and Explanation

The Correct Answer is C

0745.. Regular insulin has an onset of action of 30 to 60 minutes, a peak effect of 2 to 4 hours, and a duration of action of 6 to 8 hours. Therefore, the patient should receive breakfast within 30 minutes of receiving the insulin injection to prevent hypoglycemia.

Choice A. 0720 is incorrect because it is too soon after the injection and the insulin may not have reached its onset of action yet.

Choice B. 0815 is incorrect because it is too late after the injection and the insulin may have reached its peak effect by then, increasing the risk of hypoglycemia.

Choice D. 0730. is incorrect because it is less than 30 minutes after the injection and the insulin may be approaching its peak effect.
