A nurse is caring for a client who has a chest tube drainage system with a dry suction water seal. Which of the following actions should the nurse take?

Nursing care of a client with a chest tube drainage system requires maintaining a closed, gravity-assisted system that promotes effective drainage of air or fluid from the pleural space. A dry suction water seal system depends on correct positioning, patency, and prevention of backflow to ensure proper lung re-expansion. Chest tube management includes preventing obstruction, maintaining sterility, and ensuring the system functions below the level of the chest. Proper handling prevents complications such as tension pneumothorax or impaired drainage. Rationale: A. Stripping the chest tube tubing is contraindicated because it can create excessive negative pressure within the pleural space. This may cause tissue damage, increased pain, or trauma to lung structures. Current practice discourages routine stripping or milking of chest tubes unless specifically ordered due to potential harm. B. Emptying the drainage system every shift is not appropriate because the collection chamber is not routinely emptied during use. The system is typically replaced when full or as per institutional policy using sterile technique. Improper handling can introduce infection or disrupt the closed drainage system. C. Placing the drainage system lower than the client’s chest is correct because gravity assists in proper drainage of air and fluid from the pleural space. This positioning prevents backflow of drainage into the chest cavity. Keeping the system below chest level is a fundamental safety requirement for effective chest tube function. D. Coiling excess tubing next to the client’s side is inappropriate because it may create dependent loops that obstruct drainage flow. Tubing should be kept straight and free of kinks or dependent sections to maintain continuous suction and prevent fluid accumulation. Proper tubing alignment ensures uninterrupted drainage and reduces complication risk.
