A client is 1-day postoperative following a left lower lobectomy and has a chest tube in place. When assessing the client's three-chamber drainage system, the nurse notes that there is no bubbling in the suction control chamber. Which of the following actions should the nurse take?
- A. Continue to monitor the client as this is an expected finding.
- B. Add more water to the suction control chamber of the drainage system.
- C. Verify that the suction regulator is on and check the tubing for leaks.
- D. Milk the chest tube and dislodge any clots in the tubing that are occluding it.
Correct Answer: C
Rationale: The correct answer is C: Verify that the suction regulator is on and check the tubing for leaks.
Rationale:
1. Lack of bubbling in the suction control chamber indicates suction may not be working.
2. Checking the suction regulator ensures it is on and at the correct level for proper drainage.
3. Checking tubing for leaks ensures the system is intact and functioning properly.
4. This intervention addresses the potential issue of inadequate suction, which can affect the client's postoperative recovery.
Summary:
- Option A: Continuing to monitor is not appropriate as lack of bubbling suggests an issue with suction.
- Option B: Adding more water to the suction control chamber is unnecessary and does not address the root cause.
- Option D: Milking the chest tube is not recommended as it can cause trauma and dislodging clots may lead to complications.
