Final answer:
Continuous bubbling in the water-seal chamber of a chest tube drainage system indicates a possible air leak and should be reported to the provider.
Step-by-step explanation:
A nurse is assessing a client with a chest tube that is attached to a water-seal drainage system, and the observation that should be reported to the provider is continuous bubbling in the water seal chamber. Continuous bubbling may indicate the presence of an air leak, which could suggest that there is a problem with the chest tube system or that the patient's lung has not fully re-expanded and sealed. Fluctuation of water in the water-seal chamber with inspiration and expiration (also known as tidaling) is normal, as it indicates that the system is responsive to changes in intrathoracic pressure. Similarly, slight tidaling in the water-seal chamber with respiration is expected. The absence of drainage in the collection chamber is not necessarily a cause for alarm, as drainage may decrease over time as the patient heals. However, if there is a sudden cessation of drainage when there was previously a consistent amount, it may need to be reported, as it could suggest a blockage in the chest tube.
