A nurse is providing care to a client who has a chest tube. Which of the following should the nurse expect to implement?

A. Tubing should be kept straight and free of kinks or coils to ensure proper drainage, not coiled or hung. B. The drainage system should be kept below the client’s chest level to prevent backflow of fluid into the pleural space. C. Assessing vital signs every 30 minutes for the first 3 hours is appropriate to monitor for complications after chest tube insertion. D. Bubbling in the water seal chamber is expected with coughing or exhalation; continuous bubbling may indicate an air leak, so assessing for bubbling is important but not specifically with exhalation or cough only.
