Emergency Medical Technician (EMT) Trauma Practice Test

One step of proper treatment for an open chest wound is to assist ventilation and prep for transport because an open chest wound can lead to a condition called tension pneumothorax, where air accumulates in the chest cavity and puts pressure on the lungs and heart. By assisting ventilation, you are helping the patient breathe better despite the injury, and prepping for transport ensures that the patient receives further care at a medical facility promptly.

Covering the wound with a porous dressing (Option B) may seem like a good idea, but it is essential to first address the potential tension pneumothorax by assisting ventilation.

Preventing air from entering the wound (Option C) is not recommended because the air needs to escape to prevent tension pneumothorax.

Reassessing ventilatory status (Option D) is important but should come after providing initial treatment such as assisting ventilation and prepping for transport.
