What does the peak mean when giving insulin?

• A. Time insulin is administered
• B. When the insulin works to its maximum to lower the blood sugar
• C. Time until onset
• D. When insulin concentration is highest in the serum

Answer: (B)

Peak is the time when insulin’s glucose-lowering effect is strongest. After injection, insulin begins to work (onset), reaches its maximum effect at peak, and then the effect tapers off as the insulin wears off (duration). This period of maximum action is clinically important because hypoglycemia is most likely to occur during the peak, so glucose checks and any needed snacks or dose adjustments are focused around this time. Different insulin types have different peak patterns: rapid-acting insulins peak relatively soon after dosing, regular insulin has a later peak, intermediate-acting insulins have a longer peak window, and long-acting insulins typically have no sharp peak.
