A nurse is caring for a client who has a disposable three-chamber chest tube in place. Which of the following findings should indicate to the nurse that the client is experiencing a complication?
A.
Continuous bubbling in the water-seal chamber
B.
Occasional bubbling in the water-seal chamber
C.
Fluctuations in the fluid level in the water-seal chamber
D.
Constant bubbling in the suction-control chamber
The correct answer and Explanation is :
The correct answer is A. Continuous bubbling in the water-seal chamber.
Explanation:
A disposable three-chamber chest tube system typically includes:
- Drainage Chamber: Collects fluid and air from the pleural space.
- Water-Seal Chamber: Prevents air from re-entering the pleural space and allows for the observation of air leaks.
- Suction-Control Chamber: Regulates the level of suction applied to the chest tube.
Continuous Bubbling in the Water-Seal Chamber:
Continuous bubbling in the water-seal chamber is indicative of an air leak in the system. The water-seal chamber is designed to act as a one-way valve, allowing air and fluid to escape from the pleural space while preventing outside air from re-entering. If there is a continuous bubble in this chamber, it suggests that there is an ongoing air leak, which could be from the chest tube insertion site, a disconnected or loose connection, or a malfunction in the system. This is considered a complication because it can affect the effectiveness of the chest tube in re-expanding the lung and maintaining appropriate pleural pressure.
Occasional Bubbling in the Water-Seal Chamber:
Occasional bubbling in the water-seal chamber can be normal, particularly if the client has an air leak that is gradually resolving. It can also be seen when air is being evacuated from the pleural space but is not necessarily a sign of a significant issue unless it becomes continuous.
Fluctuations in the Fluid Level in the Water-Seal Chamber:
Fluctuations in the fluid level, known as tidaling, are typically normal and reflect changes in intrathoracic pressure with respiration. It indicates that the system is functioning correctly in terms of accommodating changes in pressure.
Constant Bubbling in the Suction-Control Chamber:
Constant bubbling in the suction-control chamber is expected and normal if the suction is set up properly. This chamber allows for continuous air to escape, which is essential for maintaining the prescribed level of suction.
In summary, while occasional bubbling in the water-seal chamber and fluctuations in the fluid level are usually normal, continuous bubbling signifies an air leak, which should prompt further assessment and possible intervention.
