If a patient with a chest tube suddenly has drainage stop, which intervention is most appropriate to assess the cause?

• A. Reposition the patient
• B. Have the patient cough and deep breathe
• C. Inspect the chest tube and drainage system for kinks or occlusion
• D. Assess lung sounds to determine lung expansion

Answer: (D)

When a chest tube drainage stops, the priority is to quickly assess how the lung is expanding. Auscultation of the lungs provides immediate information about whether the affected lung is re-expanding and how well ventilation is occurring. If breath sounds on the affected side are present and equal, the chest tube may have accomplished its goal or the system may be occluded, and you would then inspect the drainage system as the next step. If breath sounds are diminished or absent, this suggests the lung is not expanding properly, signaling a potential problem such as a blockage in the tube or a new complication that needs prompt attention. Repositioning the patient or having the patient cough and deep breathe are supportive but do not directly clarify the cause of the stopped drainage. Inspecting the chest tube and drainage system remains important, but the most informative immediate action is to assess lung expansion through auscultation.
