ECG Question #28


A nurse caring for a client in the Intensive Care Unit notices an increase in premature ventricular contractions (PVCs) on the monitor from three per minute to 5 per minute. Three minutes later, the number of PVCs increased to 9 per minute. The nurse’s first action is to:


  1. increase the infusion rate of NS currently infusing
    • Rationale:
  2. Notify the physician promptly
    • Rationale:
  3. Administer oxygen by face mask
    • Rationale:
  4. Administer an extra dose of propofol
    • Rationale:



An increase in frequency of PVCs may initiate life-threatening arrhythmias which include ventricular tachycardia, ventricular fibrillation, and other rhythms. More than 6 PVCs in a minute is serious. Increasing fluids and providing oxygen will not reduce the number of PVCs. Propofol is not indicated as a treatment for PVC.
