JBL Trauma Practice Test

In cases of a neck injury where a patient is showing signs of air embolism, the priority is to manage the airway and prevent the entry of air into the vascular system. Applying direct pressure with a sterile dressing is crucial because it helps to seal the wound in the neck, which can minimize the risk of air being sucked into the bloodstream. This step is essential for stabilizing the situation, as air embolism can lead to serious complications, including cardiovascular and neurological deficits.

Monitoring vital signs closely and administering supplemental oxygen are important secondary interventions but don't address the immediate risk of air entering the circulatory system through the neck injury. A quick head-to-toe assessment, while important in overall patient evaluation, does not directly intervene to prevent air embolism in a timely manner. Thus, the most urgent and appropriate action in this scenario is to apply direct pressure to the wound to help control the situation.
