Which statement describes a hemothorax?

• A. Non-compressible hemorrhage
• B. Air in pleural space
• C. Free intra-abdominal fluid
• D. Airway obstruction

Answer: (A)

A hemothorax is blood accumulating in the pleural space, the gap between the lungs and the chest wall. This blood collection crowds the lung, limits its expansion, and can lead to breathing trouble and shock if large. It is not air in the pleural space (that would be a pneumothorax), not free fluid in the abdomen (that would be intraperitoneal bleeding), and not an issue with the airway. Signs you’d expect include decreased or absent breath sounds on the affected side and dullness to percussion. Treatment focuses on removing the blood and allowing the lung to re-expand, typically with a chest tube and close monitoring for ongoing bleeding.
