Which statement best describes spontaneous pneumothorax?

• A. Air in the pleural space without trauma
• B. Air in the lung tissue
• C. Blood in the pleural space
• D. Air in the peritoneal cavity

Answer: (A)

Spontaneous pneumothorax is air that collects in the pleural space without any trauma or chest procedure causing it, causing the lung to collapse on the affected side. The key idea is that the air is in the pleural space, not inside the lung tissue or elsewhere. This is different from air in the lung tissue (which is not a pneumothorax), blood in the pleural space (hemothorax), or air in the abdominal cavity (pneumoperitoneum). In practice, a spontaneous event often presents with sudden chest pain and shortness of breath, and management focuses on monitoring, providing oxygen, and rapid transport to definitive care.
