A client has a newly inserted chest drainage system with a water seal. Which of the following actions should be taken?
Correct Answer: B
Rationale: The correct answer is B: Keep the collection device below the level of the client's chest. This is important to ensure proper drainage and prevent backflow or air from entering the pleural space. Placing the collection device below the chest allows gravity to assist in drainage. Clamping the tube while ambulating (choice A) can lead to increased pressure in the chest, risking complications. Coiling the tubes (choice C) may cause kinks, obstructing drainage. Positioning the client flat (choice D) can lead to leaks in the tubing due to elevated pressure.
