A nurse is contributing to the plan of care for a client who has a chest tube set to continuous suction to relieve a pneumothorax. Which of the following interventions should the nurse include?

A. Place the client in a supine position: Supine positioning is not recommended for clients with a chest tube, as it can impair lung expansion and increase the risk of respiratory complications. Upright or semi-Fowler’s positioning promotes optimal lung re-expansion. B. Clamp the chest tube every 4 hr: Clamping a chest tube unnecessarily can cause tension pneumothorax or fluid accumulation. Chest tubes should only be clamped temporarily under specific provider orders or for troubleshooting, not routinely. C. Ensure the device is kept below the level of the client's chest: Keeping the collection device below chest level prevents backflow of fluid or air into the pleural space. This is a critical safety measure to maintain proper drainage and prevent complications. D. Empty the collection chamber every 8 hr: The collection chamber is designed to be self-contained and does not require routine emptying by nursing staff. Interfering with the sealed system can disrupt suction and introduce infection risk.
