Difficulty: HardReduction of Risk Potential

A nurse is caring for a client receiving parenteral nutrition via a subclavian central venous catheter (CVC). Upon entering the room, the nurse discovers the IV tubing has disconnected from the catheter hub. The client is suddenly grasping their chest, gasping for air, and reporting a feeling of impending doom. Arrange the following nursing actions in the correct order of priority to manage this life-threatening complication.

  1. 1Clamp the central venous catheter immediately.
  2. 2Place the client in the left lateral Trendelenburg position.
  3. 3Administer 100% oxygen via a non-rebreather mask.
  4. 4Notify the healthcare provider and the rapid response team.
  5. 5Obtain a full set of vital signs and assess cardiopulmonary status.

Answer

First, clamp the catheter; second, position the client in left lateral Trendelenburg; third, administer oxygen; fourth, notify the healthcare provider; and finally, obtain vital signs.
In the event of a disconnected CVC and suspected air embolism, the nurse must prioritize actions using the ABCs and immediate life-saving physical interventions. The sequence must proceed from stopping the source of the harm (clamping), mitigating the anatomical damage (left lateral Trendelenburg positioning), supporting physiological function (oxygen), escalating care (calling for help), and finally, gathering systemic data (vital signs).

Step-by-Step Solution

1
Clamp the CVC
Stops further air entry into the vascular system.
Preventing the embolus from enlarging is the most critical first step in risk reduction.
2
Position in left lateral Trendelenburg
Traps the air in the right atrium.
Prevents the air bubble from acting as a complete mechanical obstruction in the right ventricular outflow tract.
3
Administer 100% oxygen
Alleviates tissue hypoxia and reduces bubble size.
Increases the diffusion gradient, helping nitrogen wash out of the air bubble, causing it to shrink.
4
Notify HCP and Rapid Response
Summons advanced medical intervention.
The client may require vasopressors, intubation, or needle aspiration of the air by a physician.
5
Obtain vital signs
Establishes a baseline for ongoing monitoring.
Provides data to the arriving response team about the client's hemodynamic stability following the initial interventions.
