The nurse is planning discharge teaching for a client with type 2 diabetes mellitus who has a new prescription for insulin glargine. Which action should the nurse plan to include in the discharge teaching?

A) Teach the client self-injection skills for daily subcutaneous administration: Insulin glargine is a long-acting insulin that is typically administered once daily via subcutaneous injection. Teaching the client how to properly administer insulin injections is crucial for managing type 2 diabetes effectively. Proper technique and routine are essential for ensuring correct dosing and preventing complications. B) Demonstrate how to select dose based on before-meal blood sugar readings: Insulin glargine is not used for adjusting doses based on pre-meal blood sugar readings; it provides a steady baseline of insulin coverage throughout the day. Dose adjustments for type 2 diabetes are generally not based on meal-time glucose readings with long-acting insulin. C) Explain to the family how to inject this medication for severe hypoglycemia: Insulin glargine is used to maintain long-term glucose control and is not typically used in emergency situations like severe hypoglycemia. Emergency treatment for severe hypoglycemia generally involves glucose administration rather than insulin injections. D) Provide information on increasing medication dosage if ketoacidosis occurs: Insulin glargine is not adjusted based on acute conditions such as ketoacidosis. Management of diabetic ketoacidosis involves more immediate insulin and fluid management strategies, and dosage adjustments should be guided by a healthcare provider, not based on routine discharge instructions.
