Question 1 of 5
A nurse is assessing a client who has a chest tube with a water seal drainage system. Upon assessment, the nurse notes tidaling in the water seal. Which of the following is an explanation for the tidaling?
Correct Answer: C
Rationale: The correct answer is C: The system is working properly. Tidaling in the water seal chamber is an expected finding in a chest tube with a water seal drainage system. Tidaling occurs as a result of pressure changes during inhalation and exhalation, indicating that the system is functioning as intended. This movement of fluid back and forth in the water seal chamber is a normal physiological response in the presence of a chest tube.
Incorrect answers:
A: The lung has re-expanded - Tidaling does not necessarily indicate lung re-expansion. Tidaling is a mechanical phenomenon related to the functioning of the drainage system.
B: There is a loop of tubing below the drainage system - This would be more likely to cause an issue with drainage rather than tidaling in the water seal.
D: The tubing is partially obstructed by clots - This would lead to decreased or absent drainage rather than tidaling in the water seal.
