Question 1 of 5
A patient with diabetes is starting on insulin therapy. Which type of insulin will the nurse discuss using for mealtime coverage?
Correct Answer: A
Rationale: Lispro (Humalog) is a rapid-acting insulin analog designed for mealtime glucose control. It begins action within 15 minutes, peaks in 1 hour, and lasts 2 to 4 hours. Its quick onset matches postprandial glucose spikes, enhancing glycemic control during meals and preventing hyperglycemia from carbohydrate intake. Glargine (Lantus) is a long-acting basal insulin with no peak and prolonged action. It does not target mealtime spikes but provides steady glucose control over 24 hours. Its slow onset and constant release profile are unsuitable for immediate postprandial glucose management. Detemir (Levemir) is a long-acting basal insulin, similar to glargine, with extended action for baseline glucose control. It lacks the rapid onset needed for mealtime management, making it inappropriate for postprandial hyperglycemia control, as observed in Lispro efficacy. NPH (Humulin N) is an intermediate-acting insulin with delayed onset and peak activity. It supports baseline glucose regulation but fails to address mealtime glucose control promptly. Its time profile does not align with the immediate needs of postprandial hyperglycemia management.
