A 32-year-old patient with diabetes is starting on intensive insulin therapy. Which type of insulin will the nurse discuss using for mealtime coverage?

  • A. Lispro (Humalog)
  • B. Glargine (Lantus)
  • C. Detemir (Levemir)
  • D. NPH (Humulin N)
Correct Answer: A

Rationale: The correct answer is A: Lispro (Humalog). Lispro is a rapid-acting insulin that is ideal for mealtime coverage in intensive insulin therapy because it mimics the body's natural insulin response after a meal, providing quick and effective blood sugar control. Lispro has a rapid onset of action, peaks quickly, and has a shorter duration of action compared to other types of insulin. This makes it suitable for covering the rise in blood sugar levels that occurs after meals.

Summary of why other choices are incorrect:
B: Glargine (Lantus) is a long-acting insulin used for basal coverage, not for mealtime coverage.
C: Detemir (Levemir) is an intermediate-acting insulin used for basal coverage, not for mealtime coverage.
D: NPH (Humulin N) is an intermediate-acting insulin with a slower onset and longer duration of action, making it less suitable for mealtime coverage in intensive insulin therapy.
