After administering lispro at 0800, when should the nurse remind the client to eat?

When considering the administration of lispro insulin, it's essential to understand its pharmacokinetics. Lispro is a rapid-acting insulin that typically begins to lower blood glucose levels within 15 minutes of injection, reaches its peak effect around 1 to 2 hours, and has a duration of action of about 3 to 4 hours.

Given this profile, it is crucial for the client to consume food shortly after the administration of lispro to prevent hypoglycemia. The optimal time to remind a client to eat would be approximately 15 minutes after administration, which aligns with the onset of action for this type of insulin. Therefore, advising the client to eat at 0815, just 15 minutes post-injection, supports timely glucose intake to match the insulin's activity and helps maintain stable blood sugar levels. This approach is particularly important for managing diabetes effectively, as the timing of meals and insulin administration is critical in preventing complications such as hypoglycemia.
