Which statement justifies keeping the chest drainage system below the chest level?

• A. Keeps the drainage system below chest level to promote drainage
• B. Clamping the tube when moving the client is advisable
• C. The drainage system should be above the chest level
• D. Secure the catheter with a safety pin to the dressing

Answer: (A)

Keeping the chest drainage system below the chest level uses gravity to move air and fluid from the pleural space into the collection chamber, while maintaining a closed, unidirectional path. When the collection device is below the chest, drainage occurs more reliably and the risk of air or fluid backing up into the chest is minimized, which helps prevent complications like pneumothorax. Placing the system above chest level can allow backflow or air entry, disrupting drainage. Clamping the tube during movement is not advised because it can trap air or fluid and potentially cause tension issues. The catheter should be secured with proper dressing and tubing fixation rather than with a safety pin, which poses a risk of injury and infection.
