While caring for a client with bilateral chest tubes, the bubbling in the water-seal chamber of the right chest tube stops. What action is most important for the nurse to take?

  • A. Check the chest tube connections to the water-seal container
  • B. Replace the water-seal collection container
  • C. Increase the amount of wall suction connected to the right chest tube
  • D. Milk the tubing connected to the right chest tube
Correct Answer: A

Rationale: The most important action for the nurse to take when the bubbling in the water-seal chamber of the right chest tube stops is to check the chest tube connections to the water-seal container. This is crucial to ensure there are no disconnections or leaks affecting the bubbling. Replacing the water-seal collection container (choice B) is not necessary unless there is a malfunction; increasing suction (choice C) without assessing the connections can be harmful, and 'milking' the tubing (choice D) is an inappropriate action that can cause damage to the system.
