After administering intermediate-acting insulin, when might the nurse expect to see its peak effect?

Intermediate-acting insulin typically reaches its peak effect about 4 to 12 hours after administration. This timing can vary slightly based on individual factors and the specific formulation used, but generally, the expected peak would be aligned with the time frame indicated in the third choice.

The rationale for expecting the peak action to occur between 1200 and 1600 is linked to the pharmacokinetics of intermediate insulin formulations, such as NPH insulin. Since this type of insulin is often administered in the morning, the peak time falls within that window, which is ideal for managing blood glucose levels that may rise after meals.

Insulin's peak effect is crucial for managing and predicting blood glucose levels effectively, especially in individuals with diabetes. Recognizing this peak allows nurses and caregivers to monitor and adjust dietary intake or administer additional insulin as required to maintain glycemic control.
