The nurse needs to monitor a client's blood sugar after administration of insulin regular (Humulin R). When does the nurse expect to assess the client's blood sugar based on the peak action of the medication?

A. In 15 to 30 minutes: This is the onset time for regular insulin, not the peak. Blood sugar monitoring during this period may not yet reveal the full effect of the insulin. B. In 1 to 2 hours: This is too early for the peak of regular insulin. Hypoglycemia risk is lower during this period compared to the 2 to 4-hour peak window. C. In 4 to 6 hours: This is nearing the end of the action duration for regular insulin, so monitoring blood sugar at this time would be less effective for identifying hypoglycemia risk at the peak. D. In 2 to 4 hours: This is the peak action time for regular insulin, when blood glucose should be monitored closely for potential hypoglycemia.
