During a medication administration and meals CE activity, which statement demonstrates correct understanding about timing of rapid-acting insulin?

• A. Proton pump inhibitors should be given with breakfast
• B. Glucocorticoids should be taken on an empty stomach
• C. Rapid-acting insulins should be given 10-15 minutes before meals
• D. Levodopa-Carbidopa should be taken with a high-protein snack

Answer: (C)

Timing insulin to match the meal is key. Rapid-acting insulins start working quickly, about 10–15 minutes after a dose, peak in roughly 1–2 hours, and last about 3–5 hours. Giving them 10–15 minutes before a meal lines up their action with the rise in blood glucose from eating, helping to prevent post-meal hyperglycemia and reducing the risk of hypoglycemia from a mismatch in timing. If given too early, their effect may wane before the meal raises glucose; if given after starting to eat, the glucose surge can occur before insulin begins lowering it. The other statements relate to timing or administration of different drugs and don’t address rapid-acting insulin timing.
