Question 1 of 5
Insulin lispro (Humalog) is what type of insulin?
Correct Answer: A
Rationale: Insulin lispro (Humalog) is a rapid-acting insulin that begins to lower blood glucose within 15 minutes of injection, with a peak effect occurring in 30 minutes to 1 hour. It mimics the insulin release following a meal, allowing for better postprandial glucose control. Intermediate-acting insulin, such as NPH, has an onset of 1.5 to 4 hours and provides blood glucose control over an extended period. Insulin lispro does not fit this profile, as it acts quickly and is used for meal-time glucose management. Long-acting insulins, such as glargine or detemir, have no peak and provide basal glucose control for 24 hours or more. Lispro is not suitable for basal control due to its rapid action and short duration.
