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. "Empty the collection chamber every 8 hr." The collection chamber should not be emptied on a regular schedule like every 8 hours. It should be emptied when it becomes full or according to facility policy. Regular monitoring of the chamber is essential to assess drainage and ensure it does not exceed capacity. B. "Place the client in a supine position." The client should not be placed in a supine position when a chest tube is in place for a pneumothorax. The optimal position is typically sitting up or at least semi-Fowler’s position to facilitate lung expansion and drainage. C. "Ensure the device is kept below the level of the client's chest." Keeping the chest tube drainage system below the level of the client’s chest is crucial for proper drainage and to prevent backflow of fluid or air. This position facilitates gravity drainage and helps maintain the effectiveness of the suction. D. "Clamp the chest tube every 4 hr." Clamping the chest tube is generally not recommended unless specifically ordered by a healthcare provider. Clamping can lead to increased pressure in the pleural space and risk of tension pneumothorax. The nurse should avoid clamping unless there is a clear and appropriate reason to do so.
