A nurse is collecting data from a client who has a right pneumothorax and a chest tube. Which of the following findings should the nurse report to the provider?

The scenario involves assessing a client with a pneumothorax and an active chest tube drainage system. Knowledge of pleural mechanics, chest tube function, and signs of respiratory decompensation must be applied to identify complications. Choice A rationale Drainage of 60 mL/hr is within acceptable postoperative parameters, as hourly output exceeding 70 to 100 mL/hr typically signifies active hemorrhage. This finding indicates normal chest tube function and requires continued monitoring. Choice B rationale Continuous bubbling in the suction control chamber is an expected, normal finding that confirms the ordered negative pressure suction is operating correctly. It must not be confused with intermittent bubbling in the water-seal chamber. Choice C rationale A further decrease in breath sounds indicates worsening lung collapse, a tension pneumothorax, or chest tube occlusion. This finding reflects respiratory deterioration and requires immediate provider notification and rapid clinical intervention. Choice D rationale Serous drainage on the dressing is an expected finding from localized tissue trauma at the insertion site. As long as the drainage is not frankly sanguineous or purulent, it represents normal wound healing.
