If a chest x-ray shows that the affected lung is fully reexpanded, what should the nurse anticipate observing in the chest tube system?

• A. Continuous gentle suction in the suction control chamber
• B. Absence of bubbling in the water seal chamber
• C. Drainage from the chest tube has stopped
• D. Intermittent bubbling in the water seal chamber

Answer: (A)

When a chest x-ray indicates that the affected lung is fully reexpanded, it is important to understand what this means for the chest tube system. In such a scenario, the presence of continuous gentle suction in the suction control chamber indicates that the system is still actively managing drainage and ensuring that any remaining air or fluid is being removed from the pleural space. This is particularly crucial for maintaining lung function and preventing re-accumulation of fluid or air. While it is possible that there may be limited drainage once the lung is reexpanded, suction is typically maintained until it is determined that the lung is stable and no further drainage is necessary. The continued presence of gentle suction contributes to the stability of the lung and further minimizes the risk of complications. Considering the other answer choices, it is incorrect to expect the absence of bubbling in the water seal chamber, as some level of bubbling could still occur due to the dynamics of fluid drainage and air presence. Drainage from the chest tube may continue even if the lung is reexpanded; it doesn't mean that drainage has completely stopped. Intermittent bubbling in the water seal chamber can indicate that there may still be some degree of air leak or fluid movement, which is not typical for completely reexpanded lungs. Therefore
