A nurse is planning care for a client who has a chest tube. Which of the following interventions should the nurse include in the plan? (Select all that apply.)

A. Marking the drainage output on the collection chamber at regular intervals helps track trends in drainage volume and detect complications such as sudden increases (possible hemorrhage) or decreases (possible obstruction). B. The collection chamber should always be kept below the level of the chest to promote drainage and prevent backflow of fluid into the pleural space. C. Adding sterile water to the water seal chamber as it evaporates maintains the proper fluid level (usually 2 cm). This ensures the water seal remains intact to prevent air from re-entering the pleural space. D. Clamping the chest tube routinely can cause a buildup of air and tension pneumothorax. It should only be done briefly when changing the drainage system or assessing for leaks under provider direction. E. Stripping the tube vigorously creates excessive negative pressure, which can damage lung tissue and disrupt the pleural seal. It is contraindicated.
