What is the next step after needle decompression in a tension pneumothorax?

• A. Administer antibiotics only
• B. Place a chest tube to evacuate air/bleed and re-expand the lung
• C. Perform abdominal exam
• D. Order CT immediately

Answer: (B)

In tension pneumothorax, relieving the pressure quickly is lifesaving, but you need definitive treatment to prevent recurrence. After needle decompression, placing a chest tube (thoracostomy) is the next step because it provides a continuous pathway for air to escape and any accumulated blood to drain, allowing the lung to re-expand and the mediastinal structures to return toward midline. This chest tube becomes the ongoing treatment, not just a momentary relief. Antibiotics aren’t indicated unless there’s an infection, and performing an abdominal exam won’t address the collapsed lung and mediastinal shift. A CT scan isn’t appropriate in an unstable patient because it delays definitive management and can worsen the situation. The chest tube line is the move that directly fixes the problem and stabilizes the patient.
