Difficulty: MediumReduction of Risk Potential

A client on a medical-surgical unit is receiving continuous intravenous fluids through a central venous catheter. The client suddenly reports severe chest pain and shortness of breath. The nurse notes that the intravenous tubing has become disconnected from the catheter hub. Arrange the following nursing actions in the most appropriate order of priority to reduce the client's risk of further physiological complications.

  1. 1Clamp the central venous catheter immediately.
  2. 2Place the client in a left lateral Trendelenburg position.
  3. 3Administer 100% oxygen via a non-rebreather mask.
  4. 4Notify the rapid response team and the healthcare provider.
  5. 5Assess and record the client's vital signs and respiratory status.

Answer

The correct sequence of actions for a suspected air embolism is to first clamp the catheter, then place the client in a left lateral Trendelenburg position, administer oxygen, notify the rapid response team, and finally assess vital signs.
When an air embolism is suspected due to a disconnected central venous catheter, the immediate priority is to stop further air from entering by clamping the line. The next critical step is positioning the client in a left lateral Trendelenburg position to trap the air in the right ventricle and prevent pulmonary entry. Following this, oxygen administration treats hypoxia and helps absorb the gas. Only after these direct life-saving measures are taken should the nurse notify the rapid response team and then proceed to assess and document vital signs.

Step-by-Step Solution

1
Identify the immediate life-threatening complication.
The disconnected central venous catheter tubing combined with symptoms of chest pain and shortness of breath indicates a high risk for an air embolism.
Rapid recognition of a life-threatening complication is required to initiate proper risk reduction measures.
2
Determine the priority intervention to stop the cause.
The nurse's first action must be to clamp the central venous catheter.
Clamping the catheter immediately halts the entry of environmental air into the venous system.
3
Select the appropriate position to minimize physiological harm.
The client should be placed in the left lateral Trendelenburg position.
This specific position traps the air in the apex of the right ventricle, preventing it from migrating forward into the pulmonary artery and causing a massive pulmonary embolism.
4
Support the client's oxygenation needs.
Administer oxygen via a non-rebreather mask.
High-concentration oxygen treats hypoxemia and creates a diffusion gradient that assists in the absorption of the nitrogen gas contained in the air embolus.
5
Escalate care and begin continuous monitoring.
Notify the rapid response team and healthcare provider, then assess vital signs.
Once immediate physical interventions are complete, the nurse must seek advanced medical support and continue monitoring the client's hemodynamic status for deterioration.
