A nurse is performing a tubing change on a client's central venous catheter. The tubing accidentally disconnects, and the client suddenly develops severe dyspnea, tachycardia, and a feeling of impending doom. Suspecting an air embolism, arrange the following nursing interventions in the order they should be performed to minimize client risk. All options must be used.
- 1Clamp the central venous catheter immediately.
- 2Position the client in the left lateral Trendelenburg position.
- 3Administer high-flow 100% oxygen via a non-rebreather mask.
- 4Activate the rapid response team and notify the healthcare provider.
- 5Obtain a complete set of vital signs and monitor cardiopulmonary status.
Answer
The correct sequence is to first clamp the catheter, then position the client in the left lateral Trendelenburg position, administer oxygen, notify emergency personnel, and finally assess vital signs.
When an air embolism is suspected during central line care, prioritizing actions correctly is critical to reduce risk potential. The absolute first priority is to clamp the catheter to stop the source of the air. Next, the nurse must place the client in a left lateral Trendelenburg position (Durant's maneuver) to trap the air in the right ventricle apex. After positioning, 100% oxygen is applied to treat hypoxia and shrink the air bubble by washing out nitrogen. Once these immediate, life-saving actions are complete, the nurse activates the rapid response team. Finally, continuous monitoring and obtaining vital signs are performed while waiting for the team to arrive.

Key Concept
Emergency management of a central venous air embolism requires immediate mechanical intervention (clamping and positioning) prior to oxygenation, notification, or assessment.
