Which statement best describes a chest tube?

• A. It is a flexible plastic tube inserted through an incision into the side of the chest to drain air, fluid, or pus from the intrathoracic space.
• B. It is a rigid metal rod placed in the chest to collapse the lung.
• C. It stimulates coughing to clear airways.
• D. It delivers chemotherapy directly to the pleural space.

Answer: (A)

A chest tube is a flexible plastic tube placed through a small incision in the chest wall into the pleural space to drain air, fluid, or pus. This drainage lets the lung re-expand and restores proper pressure dynamics in the chest. The tube is usually connected to a drainage system with a water-seal (and sometimes suction) to prevent air from re-entering the space and to collect the contents. It’s not a rigid metal rod, it doesn’t provoke coughing, and it doesn’t deliver chemotherapy to the pleural space. Chest tubes are used for conditions like pneumothorax, hemothorax, pleural effusion, or empyema, and care involves keeping the system below chest level, monitoring drainage and air leaks, and ensuring the dressing and tubing are secure.
