For which finding should a nurse notify the doctor when assessing a client with a pneumothorax and chest tube?

When assessing a client with a pneumothorax and a chest tube, the movement of the trachea toward the unaffected side is a significant finding that warrants immediate notification of the physician. This phenomenon, known as tracheal deviation, can indicate a tension pneumothorax, a potentially life-threatening condition where air becomes trapped in the pleural cavity, leading to increased pressure that compresses the lung and shifts mediastinal structures, which includes the trachea.

In a stable situation or with simple pneumothorax, the trachea usually remains midline, but if it shifts toward the unaffected side, it suggests severe respiratory distress and possible compromised vascular circulation, which necessitates urgent medical intervention. Timely recognition and communication of this finding can be critical in preventing deterioration in the patient's condition.

The other findings, while they may be important to monitor, do not indicate an immediate risk of significant clinical deterioration. For example, bubbling in the water seal chamber during exhalation can be normal due to the dynamics of air movement through the system. Crepitus around the chest tube insertion site may suggest subcutaneous emphysema but is not always an emergency. Visibility of the eyelets on the chest tube is important for assessment but does
