A nurse is removing a non-tunneled central venous catheter (CVC) from a client's right subclavian vein. Immediately following the catheter's removal, the client suddenly gasps, exhibits severe dyspnea, clutches their chest, and their oxygen saturation rapidly drops to 84%. Suspecting an acute venous air embolism, arrange the following collaborative and nursing interventions in the priority order they must be implemented to mitigate physiological risk.
- 1Immediately apply a sterile, impermeable occlusive dressing over the catheter insertion site.
- 2Place the client in a left lateral decubitus position with the head of the bed lowered (Trendelenburg).
- 3Initiate 100% supplemental oxygen therapy via a non-rebreather face mask.
- 4Activate the rapid response team and notify the attending healthcare provider.
- 5Initiate continuous hemodynamic monitoring and prepare for potential cardiopulmonary resuscitation.
Cevap
The correct sequence for managing a suspected venous air embolism is to first seal the insertion site to prevent further air entry, position the client in the left lateral Trendelenburg position to trap the embolus, administer 100% oxygen to shrink the bubble, activate the rapid response team for advanced support, and continuously monitor for cardiovascular collapse.
The precise physiological management of an air embolism requires a deliberate deviation from standard algorithms. The absolute first priority is stopping the source of the lethal agent by sealing the open tract. The immediate second priority is mechanically sequestering the entrained air (via Durant's maneuver) to prevent it from obstructing pulmonary circulation. Only after the source is controlled and the embolus is trapped should the nurse proceed to chemical reduction of the embolus (100% oxygen) and escalating the level of care.
