A nurse is caring for a client who is 12 hr postoperative and has a chest tube to a disposable water-seal drainage system with suction. The nurse should intervene for which of the following observations?

A. Constant bubbling in the suction-control chamber is normal as it indicates that the suction is active and functioning as intended. The chamber should have steady bubbling when suction is applied.
B. Continuous bubbling in the water-seal chamber is abnormal and indicates a potential air leak. The water-seal chamber should only bubble intermittently with respiratory effort or changes in pressure; constant bubbling suggests that air is being introduced into the system, which could indicate a malfunction or an air leak at the insertion site or along the tubing.
C. Fluid-level fluctuations in the water-seal chamber are normal and should be observed, especially with breathing. The fluid levels will rise with inspiration and fall with expiration, reflecting the changes in pressure within the pleural space.
D. Bloody drainage in the collection chamber is expected immediately after surgery, particularly in the early postoperative period. It may be a sign of surgical site drainage, but if it becomes excessive or persists, further assessment is required. However, a small amount of blood in the collection chamber initially is not abnormal.

A. Clubbing of the fingernails is typically a sign of chronic hypoxia and is seen in conditions like cystic fibrosis, COPD, and other respiratory or cardiovascular diseases. It is a long-term issue and does not indicate an immediate emergency.
B. Tracheal deviation is a medical emergency and typically indicates tension pneumothorax, where air accumulates in the pleural space, shifting the trachea away from the affected side. This can compress the heart and lungs, leading to respiratory and circulatory collapse, requiring immediate action.
C. Contraction of the diaphragm may refer to normal breathing mechanics and does not indicate an immediate emergency unless it is associated with respiratory distress or failure.
D. Rhonchi are abnormal lung sounds often associated with mucus in the airways and can be heard in conditions like bronchitis or COPD. Although they may require attention, they do not represent an immediate emergency compared to tracheal deviation.
