A practical nurse (PN) is caring for a client who is receiving intravenous fluids via a central venous catheter. The client suddenly grasps their chest, gasps for air, and becomes rapidly cyanotic. Suspecting an air embolism, arrange the following emergency risk reduction actions in the priority order the PN should implement them.
- 1Clamp the central venous catheter immediately.
- 2Place the client in a left lateral Trendelenburg position.
- 3Administer high-flow oxygen via a non-rebreather mask.
- 4Activate the rapid response team and notify the supervising registered nurse (RN).
- 5Obtain a complete set of vital signs and remain with the client.
Cevap
The correct sequence is to first clamp the catheter, then place the client in a left lateral Trendelenburg position, administer high-flow oxygen, activate the rapid response team, and finally obtain vital signs while remaining with the client.
When a central venous air embolism is suspected, the immediate focus is on stopping the entry of air and preventing it from blocking pulmonary circulation. Clamping the line stops the source. The left lateral Trendelenburg position uses gravity to trap air in the right ventricle, preventing it from entering the pulmonary artery. Oxygen treats hypoxia and shrinks the bubble. Calling for advanced help and continuous monitoring follow these immediate life-saving physical interventions.
