Emergency Medical Technician (EMT) Trauma Practice Test

Immediate decompression with a needle thoracostomy followed by chest tube placement is the correct action for a patient with a suspected tension pneumothorax. This condition occurs when air becomes trapped in the pleural space and creates increased pressure, which can lead to compromised respiratory function and cardiovascular collapse. The prompt intervention of needle decompression serves to quickly relieve this pressure, allowing the lungs to re-expand and alleviating the associated life-threatening symptoms.

Following this emergency procedure, the placement of a chest tube is necessary to ensure continuous air evacuation and re-establish normal lung function. This two-step approach is critical in managing tension pneumothorax effectively and preventing further complications.

High-flow oxygen administration alone does not address the underlying issue of pressure buildup in the chest. Observing the patient without intervention could lead to worsening of their condition, as tension pneumothorax is a medical emergency that requires immediate action. Wrapping the chest tightly with bandages could exacerbate the situation by further increasing intrathoracic pressure, making it a dangerous approach in this context.
