Question

Difficulty: Very hardEstablishing Priorities

A nurse is removing a central venous catheter (CVC) from a client's right subclavian vein. Immediately after the catheter is withdrawn, the client gasps, reports sudden severe chest pain, and becomes acutely tachycardic and dyspneic with a rapidly dropping oxygen saturation. The nurse suspects a venous air embolism. Arrange the following nursing interventions in the correct order of clinical priority from first to last.

  1. 1Immediately apply an impermeable, occlusive dressing over the insertion site.
  2. 2Place the client in the left lateral Trendelenburg position.
  3. 3Administer high-flow 100% oxygen via a non-rebreather mask.
  4. 4Activate the rapid response team and notify the healthcare provider.
  5. 5Initiate continuous hemodynamic monitoring and prepare equipment for emergency intubation.

Answer

The correct sequence of prioritized interventions is to first occlude the insertion site, then place the client in the left lateral Trendelenburg position, followed by administering 100% oxygen, activating the rapid response team, and finally preparing for continuous monitoring and potential intubation.
In the event of a venous air embolism, standard ABC (Airway, Breathing, Circulation) prioritization is temporarily modified to address the immediate mechanical threat. The absolute first action must be to stop further air from entering the vessel (occluding the site). The immediate second action is to prevent the air already in the system from blocking the right ventricular outflow tract, which is achieved by placing the client in the left lateral Trendelenburg position (Durant's maneuver). Only after these two mechanical safeguards are in place should the nurse proceed to treat the resulting hypoxia with high-flow oxygen, followed by escalating the situation to the rapid response team, and finally preparing for advanced resuscitation.

Step-by-Step Solution

1
Apply an occlusive dressing over the CVC insertion site.
The entry point for atmospheric air into the venous system is sealed.
Before treating the systemic effects, the nurse must definitively stop the root cause of the acute deterioration to prevent a larger, fatal embolism.
2
Position the client in the left lateral Trendelenburg position.
The air bubble is directed toward the apex of the right ventricle.
This utilizes gravity to keep the air away from the pulmonary valve, maintaining cardiac output and preventing a catastrophic pulmonary artery occlusion.
3
Administer 100% high-flow oxygen.
Hypoxemia is treated and a diffusion gradient is created.
High concentrations of oxygen relieve ischemia and help shrink the air embolus by encouraging nitrogen to diffuse out of the bubble and into the blood.
4
Activate the rapid response team and notify the provider.
Advanced medical support is mobilized to the bedside.
The client is in critical condition and requires a multidisciplinary team for advanced life support and potential definitive procedures.
5
Initiate continuous monitoring and prepare for intubation.
The client's hemodynamic trends are tracked and emergency airway equipment is ready.
Cardiopulmonary collapse is a high risk following an air embolism, necessitating proactive preparation for full resuscitation.
