The nurse administered 25 units of Regular (Humulin/Novolin) insulin to a patient with type 1 diabetes at 1600, which intervention should the nurse implement?

A. Ensure the patient eats their bedtime snack.: While a bedtime snack can help prevent overnight hypoglycemia, the immediate priority after administering regular insulin at 1600 is to cover the meal corresponding to the insulin dose. The snack alone does not match the timing of insulin action. B. Check the patient's serum blood glucose level.: Monitoring blood glucose is important, but the key intervention immediately after giving regular insulin is to ensure the patient consumes food to prevent hypoglycemia. Lab checks alone do not provide immediate protection against low blood sugar. C. Assess the patient for hypoglycemia around 1730.: Regular insulin peaks around 2–4 hours after administration, so assessment at 1730 may be early. While monitoring is necessary, the primary action is to provide a meal to match the insulin’s onset and prevent hypoglycemia. D. Serve the patient the supper tray.: Administering regular insulin requires concurrent carbohydrate intake to prevent hypoglycemia. Serving the supper tray ensures that the insulin’s action is matched with food, maintaining safe blood glucose levels and preventing immediate
