A nurse is assessing a client who has a chest tube following a thoracotomy. Which of the following findings requires intervention by the nurse?
1 cm of water present in the water seal chamber
Tidaling with spontaneous respirations
Suction chamber pressure of -20 cm H20
Drainage collection chamber is one-third full
The Correct Answer is A
A. The water seal chamber should contain at least 2 cm of water to maintain the seal and prevent air from entering the pleural space. Only 1 cm of water is inadequate and requires intervention.
B. Tidaling, or fluctuation of water with respirations, is an expected finding and indicates that the system is functioning properly.
C. A suction chamber pressure of -20 cm H₂O is the standard setting for chest tube drainage systems and does not require intervention.
D. A drainage collection chamber that is one-third full is within normal limits and simply indicates the need to continue monitoring output.
