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: A supine position can impair lung expansion and increase the risk of respiratory complications. Clients with a chest tube are best positioned in a semi-Fowler’s or high-Fowler’s position to promote lung re-expansion and ease of breathing. B. Empty the collection chamber every 8 hr: The collection chamber in a chest drainage system should not be emptied routinely, it should be emptied as needed to prevent it from overfilling. It is a closed system, and breaking it by emptying can introduce infection or disrupt the pressure needed for effective drainage. C. Ensure the device is kept below the level of the client's chest: Keeping the chest drainage system below chest level uses gravity to promote drainage and prevents backflow of fluid or air into the pleural space. This positioning is essential to maintain the effectiveness and safety of the chest tube system. D. Clamp the chest tube every 4 hr: Routine clamping of a chest tube is not recommended as it can lead to a dangerous buildup of air (tension pneumothorax). Clamping is reserved for specific, short-term procedures under direct provider orders, such as changing the drainage system.
