A nurse is contributing to the plan of care for a client who has a pleural chest tube with a closed drainage system. Which of the following actions should the nurse recommend for the client's care?

A. Maintain 30 ml sterile water in the drainage collection chamber: The sterile water is maintained in the water-seal chamber, not the drainage collection chamber. The water-seal chamber typically holds about 2 cm of water to create a one-way valve preventing air from entering the pleural space, not 30 mL in the drainage area. B. Place the drainage device level with the tube insertion site: The drainage device should always be kept below the level of the chest tube insertion site to allow gravity to assist drainage and to prevent backflow of fluid or air into the pleural cavity, which could cause complications. C. Keep system tubing connections taped together: Taping the system tubing connections securely helps maintain a closed system, preventing accidental disconnections that could lead to air leaks or loss of the negative pressure needed for proper lung re-expansion. This is essential for the effectiveness of chest tube management. D. Empty the drainage collection chamber every 4 hr: The drainage collection chamber is not emptied routinely. Instead, it is replaced when full or according to facility protocol. Frequent opening of the system increases the risk of introducing infection or losing the closed negative-pressure system.
