A nurse is caring for a client with diabetes mellitus who is prescribed regular insulin via a sliding scale. After administering the correct dose at 0715, the nurse should ensure the client receives breakfast at which of the following times?

A. 0745: Regular insulin has a rapid onset, typically starting to act within 30 minutes after injection, with its peak effect around 2-4 hours. Ensuring the meal is given around 30 minutes after administration (0745) aligns with the insulin's onset of action and helps maintain proper blood glucose levels. B. 0730: Administering breakfast at 0730, only 15 minutes after insulin injection, may not provide enough time for the insulin to start working effectively, increasing the risk of hypoglycemia if food is not available when the insulin begins to act. C. 0720: Breakfast given just 5 minutes after insulin administration is too soon and may not align with the insulin's onset of action, potentially leading to hypoglycemia. D. 0815: Waiting 1 hour after insulin administration for breakfast increases the risk of hypoglycemia, as the insulin will be working for an extended period before the meal is introduced. It's ideal to serve breakfast 30 minutes after administration to prevent this risk.
