In a multiple daily injections regimen, what is the primary role of basal insulin versus prandial insulin?

• A. Basal provides steady background insulin; prandial covers meals and corrections
• B. Basal covers meals; prandial provides background
• C. Both do the same
• D. Basal and prandial are only for type 1 DM

Answer: (A)

In a multiple daily injections plan, the goal is to mimic normal insulin patterns by separating roles. Basal insulin provides a steady, background level that suppresses hepatic glucose production between meals and overnight, helping keep fasting glucose from drifting upward. Prandial insulin, usually rapid-acting, is taken with meals to cover the carbohydrate you’re about to eat and to provide a correction if glucose is higher than target. That combination is what keeps both fasting and post-meal glucose in check. So the best answer reflects that basal supplies the steady background insulin, while prandial handles meals and any needed corrections. The idea that basal covers meals would miss the post-meal glucose rise; treating both the same ignores their different timing and effects; and these regimens aren’t limited to type 1 diabetes—they’re used in some people with type 2 as well.
