The nurse is monitoring a client’s EKG strip and notes coupled premature ventricular contractions greater than 10 per minute.
- A. Which medication should the nurse expect to administer for a client with coupled PVCs greater than 10 per minute?
- B. Atropine sulfate (Atropine) IV.
- C. Isoproterenol (Isuprel) IV.
- D. Verapamil (Calan) IV.
- E. Lidocaine hydrochloride (Xylocaine) IV.
Correct Answer: D
Rationale: Lidocaine is the drug of choice for frequent or coupled PVCs, as it suppresses ventricular arrhythmias that could lead to ventricular tachycardia. Atropine treats bradycardia, isoproterenol is used for heart block, and verapamil is a calcium-channel blocker for supraventricular arrhythmias.
