A nurse is developing a teaching plan for an older adult client who has a new prescription for insulin glargine. Which of the following expected outcomes should the nurse include in the plan?

A. The client will use the deltoid muscle as an injection site is incorrect because insulin glargine is typically administered subcutaneously in areas such as the abdomen, thigh, or upper arm, not specifically the deltoid muscle. B. The client will administer insulin glargine before each meal is incorrect because insulin glargine is a long-acting insulin that is usually administered once daily, not before each meal. C. The client will take an additional dose of insulin glargine prior to exercise is incorrect because insulin glargine is not typically adjusted based on exercise. Instead, short-acting insulin or dietary adjustments are used to manage blood glucose levels during physical activity. D. The client will wear his reading glasses when drawing up a dose of insulin glargine is an appropriate outcome. Ensuring that the client can accurately measure and administer the correct dose of insulin is crucial for effective diabetes management and preventing dosing errors.
