Which option represents definitive drainage in a stable patient with pneumothorax?

• A. Oxygen
• B. Small-bore catheter
• C. Needle decompression
• D. Tube thoracostomy

Answer: (D)

Definitive drainage of a pneumothorax means physically removing the air from the pleural space with a device that provides ongoing drainage so the lung can re-expand. Oxygen helps the body reabsorb intrapleural air faster, but it does not evacuate the air or re-expand the lung on its own. Needle decompression is an emergency maneuver for a tension pneumothorax in an unstable patient, not a definitive treatment for a stable pneumothorax. A small-bore catheter can drain air, but the standard definitive management in a stable patient is tube thoracostomy, a chest tube inserted into the pleural space to evacuate air continuously and permit full lung re-expansion.
