A nurse is caring for a client who receives insulin lispro each morning at 0730. The nurse should anticipate the client's insulin to peak around which of the following times?

A. 1100: This time corresponds approximately to the peak of short-acting insulin (regular insulin), which typically peaks 2–4 hours after administration. Insulin lispro is rapid-acting and peaks much earlier, so 1100 is too late for peak action. B. 0830: Insulin lispro is a rapid-acting insulin that begins to work within 15 minutes, peaks in about 30–90 minutes, and has a duration of 3–5 hours. Administered at 0730, its peak effect would occur around 0830–0900, aligning with postprandial glucose control. C. 1730: This time is too late to reflect the peak of insulin lispro administered in the morning. By this time, the rapid-acting insulin would have largely worn off, and the client’s blood glucose would be influenced by basal insulin or other meals. D. 1400: This corresponds more closely to the peak of intermediate-acting insulin (NPH) administered in the morning, not rapid-acting insulin. Insulin lispro’s short peak period makes 1400 too delayed for its expected maximal effect.
