Mr Ozz, a 45-year-old insulin-dependent diabetic, is admitted to the hospital with a diagnosis of pneumonia. He has been febrile since admission. His daily insulin requirement is 24 units of NPH. Every morning Albert is given NPH insulin at 0730. Meals are served at 0830, 1230, and 1830.
The nurse expects that the NPH insulin will reach its maximum effect (peak) between the hours of:
1530 and 2130
1730 and 2330
1130 and 1330
1330 and 1930
The Correct Answer is B
Choice A rationale: This does not match the peak time of NPH insulin.
Choice B rationale: This does not match the peak time of NPH insulin.
Choice C rationale: This does not match the peak time of NPH insulin.
Choice D rationale: This is because NPH insulin is an intermediate-acting insulin that has an onset of action of 1 to 2 hours, a peak of 6 to 12 hours, and a duration of 18 to 24 hours. Therefore, if Albert is given NPH insulin at 0730, the peak effect will occur between 1330 and 1930, which means that his blood glucose level will be lowest during this time.
