Capillary glucose monitoring is being performed every 4 hours for a female client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which she receives 8 U of regular insulin. Nurse Vince should expect the dose's:

  • A. Onset to be at 2 p.m. and its peak to be at 3 p.m.
  • B. Onset to be at 2:15 p.m. and its peak to be at 3 p.m.
  • C. Onset to be at 2:30 p.m. and its peak to be at 4 p.m.
  • D. Onset to be at 4 p.m. and its peak to be at 6 p.m.
Correct Answer: C

Rationale: The correct answer is C. Regular insulin typically has an onset of action within 30 minutes and peaks 2-4 hours after administration. Given that the insulin was administered at 2 p.m., the onset of action can be expected around 2:30 p.m., and the peak effect would occur between 4-6 p.m. Choice A is incorrect as the onset and peak are too close together for regular insulin. Choice B is incorrect because the onset time is too soon after administration. Choice D is incorrect as the onset time is too delayed for regular insulin.
