A nurse is performing routine tubing changes on a client's central venous catheter (CVC). During the procedure, the catheter hub accidentally detaches from the injection cap, exposing the central lumen to room air. The client abruptly gasps, grasps their chest, and exhibits severe respiratory distress. Arrange the following nursing actions in the most appropriate order of priority.
- 1Clamp the open lumen of the central venous catheter.
- 2Position the client in the left lateral Trendelenburg position.
- 3Administer 100% oxygen using a non-rebreather mask.
- 4Activate the facility's rapid response team.
- 5Auscultate heart sounds and obtain a full set of vital signs.
Answer
The correct priority sequence is to clamp the catheter, position the client in the left lateral Trendelenburg position, administer high-flow oxygen, activate the rapid response team, and finally assess vital signs.
In acute deterioration scenarios, the nurse must prioritize actions that immediately remove the cause of the threat and stabilize airway, breathing, and circulation. Clamping the line removes the threat. Positioning prevents immediate mechanical death. Oxygen supports failing gas exchange. Getting help and assessing data naturally follow these immediate survival steps.
