A nurse is caring for a client who has a chest tube. The client asks why the fluid in the water-seal chamber rises and falls.
Which of the following statements should the nurse make?
"This indicates a possible air leak.".
"This means your lung is fully re-expanded.".
"Your breathing pattern causes this.".
"Suction pressure that is too high causes this.".
The Correct Answer is C

The fluctuation of fluid in the water-seal chamber of a chest tube is known as tidaling and is caused by the changes in pressure within the chest during respiration.
Choice A is not correct because tidaling does not indicate an air leak.
Choice B is not correct because tidaling does not necessarily mean that the lung is fully re-expanded.
Choice D is not correct because suction pressure does not cause tidaling.
