EMT Soft-Tissue Injuries Practice Test

In the case of an open chest wound with bubbling blood, applying an occlusive dressing is a critical step. This type of wound is often associated with a pneumothorax or a sucking chest wound, where air enters the chest cavity through the opening, leading to potential respiratory distress and further lung injury.

An occlusive dressing helps to create a seal over the wound, preventing additional air from entering the pleural space and allowing the lung to potentially reinflate. This is crucial because if air continues to enter the chest cavity, it can lead to a tension pneumothorax, which can be life-threatening. By sealing the wound, you help stabilize the patient’s condition and allow for proper ventilation until further medical treatment can be rendered.

The actions of controlling bleeding and preparing for transport are important, but without first addressing the immediate need to seal the chest wound, the risk of respiratory compromise increases. Similarly, while assisting with ventilations may be necessary later on if the patient's breathing is inadequate, the priority in the initial response to an open chest wound with bubbling blood is to ensure that the wound is sealed properly with an occlusive dressing.
