Which of the following is an example of a rapid-acting insulin?

Lispro is classified as a rapid-acting insulin, making it a suitable choice for managing blood glucose levels during meal times. This type of insulin begins to work quickly, typically within 15 minutes, peaks in about 1 to 2 hours, and has a duration of about 3 to 4 hours. This rapid onset allows for better control of postprandial blood sugar levels, which is important for individuals with diabetes when they eat.

In contrast, Humulin N is an intermediate-acting insulin that has a longer onset and duration, while Glargine and Detemir are both long-acting insulins that provide a steady level of insulin over an extended period, making them inappropriate choices for rapid control around meals. Understanding these classifications is crucial for effective diabetes management and ensuring that patients receive the right type of insulin at the appropriate times.
