A. Loop the tubing of the chest tube on the client's bed: Looping the tubing can create kinks and obstruct drainage, increasing the risk of complications like tension pneumothorax. B. Strip the client's chest tube every 2 hrs: Stripping the chest tube increases negative pressure in the system, which can damage lung tissue. Instead, gentle milking of the tube is acceptable if needed and directed by protocol. C. Tape the connections on the client's chest tube: Securing the connections with tape prevents accidental disconnection, which could compromise the seal and lead to complications such as a pneumothorax. D. Place the chest tube drainage system above the level of the client's heart. The drainage system should always remain below the level of the chest to facilitate gravity drainage and prevent fluid from flowing back into the pleural cavity.
