What is the immediate action if a chest tube becomes disconnected from the drainage system?

• A. Clamp the tube and leave it open
• B. Reconnect immediately to any drainage system without care
• C. Cover with a sterile dressing only
• D. Place an airtight occlusive dressing over the insertion site and notify the care team; reconnect to an appropriate drainage system if possible

Answer: (D)

When a chest tube becomes disconnected, the top priority is to prevent air from entering the pleural space and to keep the drainage area sterile. Immediately apply an airtight occlusive dressing over the insertion site to seal the wound and minimize air leaks. Then notify the care team so a replacement drainage setup can be arranged and, if possible, the chest tube can be reconnected to an appropriate drainage system. This approach protects against pneumothorax and maintains proper respiratory drainage. Avoid leaving the site open or attempting to connect to an unrelated system, as that can introduce infection or fail to maintain the necessary negative pressure.
