A nurse is evaluating teaching with a client who is receiving continuous subcutaneous insulin via an external insulin pump. Which of the following statements by the client indicates a need for further teaching?

A. "If I skip lunch, I will skip my mealtime dose of insulin.": If a client skips a meal, they should skip the mealtime dose of insulin, as the insulin is primarily used to cover the carbohydrates from food intake. This prevents hypoglycemia. B. “I will change the needle every 3 days.": For a continuous insulin infusion via an insulin pump, the infusion set, including the needle or cannula, should be changed every 2 to 3 days to reduce the risk of infection or irritation. C. "I will use insulin glargine in my insulin pump.": Insulin glargine is a long-acting insulin and is not typically used in an insulin pump. Insulin pumps generally use rapid-acting insulin, such as insulin aspart or insulin lispro, to provide both basal and mealtime coverage. D. “I should store all unused insulin in the refrigerator.": Unused insulin should be stored in the refrigerator to maintain its potency. Once opened, insulin can be stored at room temperature for a period, typically up to 28 days, depending on the type of insulin.
