After administering a dose of lispro, when should the nurse reassess the client's response to the peak effect of the insulin?

Lispro insulin, being a rapid-acting insulin, typically reaches its peak effect approximately 1 to 2 hours after administration. This peak effect is the period when the likelihood of hypoglycemia is greatest and is crucial for monitoring the patient's response to the medication.

When considering the timing of reassessment, if we assume the dose is administered at 9:15 AM, the nurse should plan to check the patient's blood glucose levels around 10:15 AM. This timing aligns with the expected peak action of lispro, allowing for appropriate evaluation of the patient's glucose response and management of any potential issues arising from the insulin's effects.

Monitoring at this time helps ensure that any required interventions, such as providing carbohydrates for hypoglycemia or adjusting further doses, can be promptly addressed.
