Question

Difficulty: HardPhysiological Adaptation

A nurse is discontinuing a client's central venous catheter (CVC). Immediately after the catheter is removed, the client gasps, reports sudden severe chest pain, and becomes distinctly cyanotic. The nurse suspects a venous air embolism. Arrange the following nursing interventions in the correct order of priority from first to last.

  1. 1Apply a sterile, occlusive dressing immediately over the insertion site.
  2. 2Position the client in the left lateral Trendelenburg position.
  3. 3Administer 100% oxygen via a non-rebreather mask.
  4. 4Notify the healthcare provider and activate the rapid response team.
  5. 5Obtain a complete set of vital signs and continuously monitor oxygen saturation.

Answer

The correct sequence of actions for a suspected air embolism is: 1) Apply a sterile, occlusive dressing, 2) Position the client in the left lateral Trendelenburg position, 3) Administer 100% oxygen, 4) Notify the healthcare provider, and 5) Obtain a complete set of vital signs.
A venous air embolism is a life-threatening emergency requiring immediate, sequential actions to prevent cardiac arrest. The first priority is always to stop the source of the problem by occluding the central line insertion site. Next, Durant's maneuver (left lateral Trendelenburg) is utilized to mechanically trap the air in the right ventricle apex, preventing pulmonary outflow obstruction. Only after securing the site and positioning the client should the nurse administer 100% oxygen to treat hypoxemia and reduce the nitrogen bubble size. Finally, the nurse calls for advanced help and continues to closely monitor the client's hemodynamic status.

Step-by-Step Solution

1
Halt the influx of air.
Apply a sterile, occlusive dressing over the central line site.
The priority is to eliminate the root cause of the crisis to prevent the air embolus from enlarging.
2
Prevent embolus migration.
Place the client in the left lateral Trendelenburg position.
This specific position (Durant's maneuver) utilizes gravity to trap the existing air in the right ventricle, preventing it from traveling into the pulmonary artery.
3
Treat hypoxia and shrink the embolus.
Administer 100% oxygen via a non-rebreather mask.
High-concentration oxygen relieves systemic hypoxemia and speeds up the reabsorption of nitrogen gas from the bubble.
4
Escalate care.
Notify the healthcare provider and rapid response team.
Advanced interventions and potential resuscitation will be required; help must be summoned.
5
Reassess and monitor.
Obtain vital signs and monitor oxygen saturation.
Continuous monitoring guides ongoing resuscitation efforts and evaluates the effectiveness of the initial interventions.

Key Concept

Management of a venous air embolism prioritizes stopping the air source, utilizing gravity to trap the air in the right ventricle (Durant's maneuver), and treating severe hypoxia.
