A nurse is preparing to administer a sympathomimetic drug. Which of the following might the nurse be preparing to give?
- A. Clonidine (Catapres)
- B. Isoproterenol (Isuprel)
- C. Midodrine (ProAmatine)
- D. Epinephrine (EpiPen)
- E. Reserpine (Serpalan)

A client is to receive midodrine. Which of the following would the nurse include in the plan of care to ensure that the client doesn't develop supine hypertension?
- A. Administer midodrine during the day.
- B. Ensure that the client is lying in a supine position.
