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

A. Milk the chest tube at least three times a day: Milking is generally not recommended as it can increase intrathoracic pressure and damage lung tissue. It should only be done with a provider’s order and specific indication. B. Empty the drainage collection chamber when full: The collection chamber is a closed system and should not be emptied. When full, the entire drainage unit should be replaced to maintain sterility. C. Ensure intermittent bubbling is present in the water seal chamber: Intermittent bubbling in the water seal chamber is expected during expiration or coughing, indicating air leaving the pleural space. However, continuous bubbling may suggest an air leak and requires evaluation. D. Clamp the chest tube when transferring the client from bed to the chair: Clamping the tube is contraindicated during transport, as it can cause tension pneumothorax. The system should remain unclamped and below chest level.
