A nurse is reinforcing discharge teaching with a client who has a new diagnosis of type 2 diabetes mellitus and a prescription for exenatide. Which of the following instructions should the nurse include in the teaching?

A. "Contact the provider if you experience unexplained muscle pain.": Muscle pain is not a typical adverse effect of exenatide; this advice would apply to statins or drugs associated with rhabdomyolysis. B. "Take the medication at bedtime.": Exenatide is usually taken twice daily, 1 hour before morning and evening meals, not at bedtime. C. "Discard excess medication after 60 days.": Exenatide pens should typically be discarded 30 days after opening, not 60 days. D. "Inject the medication into the subcutaneous tissue of your abdomen.": Correct. Exenatide is administered subcutaneously, typically in the abdomen, thigh, or upper arm.
