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

A) Provide information on increasing medication dosage if ketoacidosis occurs: While it is important for clients with diabetes to understand the signs and symptoms of diabetic ketoacidosis (DKA) and how to respond, increasing insulin dosage on their own without healthcare provider guidance could be dangerous. Adjusting insulin dosage should always be done under the direction of a healthcare provider. B) Teach the client self-injection skills for daily subcutaneous administration: Insulin glargine is a long-acting insulin used for basal (background) insulin coverage in clients with diabetes. Teaching the client how to self-administer insulin injections is essential for effective management of diabetes, especially when using long-acting insulin formulations like insulin glargine. Proper injection technique, site rotation, and storage of insulin are important aspects of this teaching. C) Demonstrate how to select dose based on before meal blood sugar readings: Insulin glargine is typically administered once daily at the same time each day and is not adjusted based on before meal blood sugar readings. Instead, it provides a steady level of insulin over 24 hours to help control blood sugar levels between meals and overnight. D) Explain to the family how to inject this medication for severe hypoglycemia: Insulin glargine is not used for the treatment of severe hypoglycemia. Instead, it is a long-acting insulin used to maintain basal insulin levels in clients with diabetes. Severe hypoglycemia is treated with fast-acting glucose sources such as oral glucose tablets, gel, or glucagon injections, and the family should be educated on these treatments instead.
