Zorluk: ZorReduction of Risk Potential

A nurse enters a client's room and discovers that the intravenous tubing has accidentally disconnected from the client's central venous catheter (CVC) hub. The client is suddenly dyspneic, coughing, tachypneic, and grasping their chest. In which order should the nurse perform the following actions to minimize the client's risk for complications? (Arrange the actions from first to last.)

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

Cevap

1. Clamp the central venous catheter. 2. Place the client in a left lateral Trendelenburg position. 3. Administer 100% oxygen via a non-rebreather mask. 4. Activate the rapid response team and notify the healthcare provider. 5. Obtain a full set of vital signs and monitor oxygen saturation.
In the event of a central line disconnection and suspected air embolism, the nurse must act immediately to reduce the risk of a fatal complication. The sequence follows a clear hierarchy: stop the source (clamp), contain the existing damage (positioning), treat the symptoms (oxygen), call for advanced help, and finally reassess.

Adım Adım Çözüm

1
Clamp the central venous catheter.
The source of the air leak is secured.
An open central line creates a pressure gradient that pulls air into the venous system. Clamping is the most rapid way to stop the ongoing physiological insult.
2
Place the client in a left lateral Trendelenburg position.
The air embolus is localized and trapped.
This specific position keeps the air bubble in the apex of the right ventricle, preventing it from migrating into the pulmonary arterial system and causing an outflow obstruction.
3
Administer 100% oxygen via a non-rebreather mask.
Hypoxia is addressed and the air bubble size is reduced.
High-flow oxygen treats tissue hypoxia and washes out nitrogen, hastening the resorption of the air bubble in the bloodstream.
4
Activate the rapid response team and notify the healthcare provider.
Advanced medical support is mobilized.
The client requires critical care interventions, which may include emergency aspiration of the air from the right atrium.
5
Obtain a full set of vital signs and monitor oxygen saturation.
A hemodynamic baseline is established for the incoming team.
Once life-saving measures are in place, the nurse evaluates the client's response to the interventions and monitors for further deterioration.
