A nurse is providing care for a client who is receiving intravenous fluids via a central venous catheter. While the nurse is untangling the tubing, the catheter cap accidentally disconnects and the line is briefly open to room air. The client suddenly gasps, develops severe dyspnea, and becomes cyanotic. In what order should the nurse perform the following actions? Arrange the interventions from first to last.
- 1Clamp the central venous catheter immediately.
- 2Place the client in the left lateral Trendelenburg position.
- 3Administer high-flow oxygen via a non-rebreather mask.
- 4Activate the rapid response team and notify the healthcare provider.
- 5Obtain a complete set of vital signs to monitor cardiopulmonary status.
Answer
The correct sequence of actions for a suspected central line air embolism is to first clamp the catheter, then place the client in the left lateral Trendelenburg position, administer high-flow oxygen, activate the rapid response team, and finally obtain a full set of vital signs.
In the event of a suspected central line air embolism, the nurse must immediately prioritize actions that prevent further air entry and minimize the physiological impact of the embolus. The very first action is source control: clamping the catheter prevents more air from being drawn into the venous system. Second, placing the client in the left lateral Trendelenburg position uses gravity to trap the air in the right ventricle, preventing it from occluding the pulmonary circulation. Third, high-flow oxygen is administered to treat acute hypoxia and reduce the size of the air bubble. Fourth, the nurse must call for advanced medical help by activating the rapid response team. Finally, the nurse remains at the bedside to obtain vital signs and continuously monitor the client until the rapid response team arrives.
