The nurse notes premature ventricular contractions (PVCs) while suctioning a patient’s endotracheal tube. Which action by the nurse is a priority?

  • A. Decrease the suction pressure to 80 mm Hg.
  • B. Document the dysrhythmia in the patient’s chart.
  • C. Stop and ventilate the patient with 100% oxygen.
  • D. Give antidysrhythmic medications per protocol.
Correct Answer: C

Rationale: The correct answer is C: Stop and ventilate the patient with 100% oxygen. This is the priority action because PVCs can lead to life-threatening arrhythmias and inadequate oxygenation. By stopping suctioning and providing 100% oxygen, the nurse ensures proper oxygenation and ventilation, which takes precedence over addressing the dysrhythmia itself. Decreasing suction pressure (choice A) may not address the underlying issue and could potentially harm the patient. Documenting the dysrhythmia (choice B) is important but not as urgent as ensuring adequate oxygenation. Giving antidysrhythmic medications (choice D) should be done under the direction of a healthcare provider and is not the first-line intervention in this situation.
