A nurse is providing teaching to an adolescent who has type 1 diabetes mellitus. Which of the following should the nurse include in the teaching?

The correct answer is B: Obtain an influenza vaccine annually. Adolescents with type 1 diabetes mellitus are at higher risk for infections, including the flu. Annual influenza vaccination is crucial to prevent complications. Taking glyburide (A) is incorrect as it is not used in type 1 diabetes. Injecting insulin in the deltoid muscle (C) is not recommended due to erratic absorption. Administering glucagon for hyperglycemia (D) is used for severe hypoglycemia, not hyperglycemia.
