A nurse in the recovery room is assessing a client who has a new chest tube. The nurse finds that the water seal is no longer tidaling. The nurse should identify the finding as resulting from which of the following?
A.
An air leak noted at the insertion site.
B.
The tubing may be kinked.
C.
Water needs to be added to the suction-control chamber.
D.
The suction is set too low.
The correct answer and Explanation is :
The correct answer is B. The tubing may be kinked.
Explanation:
Tidaling in the water seal chamber of a chest tube system refers to the fluctuation of the water level with the patient’s breathing. This fluctuation is due to the changes in intrathoracic pressure during respiration, which affects the water level in the chamber. When tidaling is present, it indicates that the chest tube system is properly connected and functioning, and that there is a change in pressure within the pleural cavity.
If tidaling stops, this can signal an issue with the chest tube system. The most common reason for the absence of tidaling is that there might be an obstruction or kink in the tubing. Kinks or clogs in the tubing can prevent air or fluid from moving freely through the system, thus preventing the normal fluctuation of the water seal chamber.
Here’s a breakdown of why the other options are less likely causes:
- A. An air leak noted at the insertion site: An air leak at the insertion site would typically cause bubbling in the water seal chamber, not a lack of tidaling. An air leak is usually associated with continuous bubbling in the water seal chamber, not the absence of tidaling.
- C. Water needs to be added to the suction-control chamber: If there is a problem with the suction-control chamber, it would usually result in issues with suction pressure or bubbling, not necessarily with the tidaling of the water seal chamber.
- D. The suction is set too low: This would more likely affect the amount of bubbling in the suction-control chamber rather than the water seal chamber. The absence of tidaling is not directly related to the suction setting but rather to obstructions or issues in the tubing.
Therefore, when assessing for the absence of tidaling, checking for kinks or obstructions in the tubing is a crucial step. Ensuring the tubing is straight and unobstructed helps restore proper tidaling and confirms the functionality of the chest tube system.
