After chest-tube removal, which action is typically recommended to confirm there is no recurrence?

• A. Observe without imaging unless symptoms indicate.
• B. Reinsert the chest tube if any chest discomfort occurs.
• C. Do not perform any imaging after removal.
• D. Obtain a post-removal chest X-ray to assess for recurrence.

Answer: (D)

After removing a chest tube, the priority is to confirm there is no re-accumulation of air or fluid in the pleural space. Obtaining a post-removal chest X-ray provides an objective assessment of lung re-expansion and can detect a recurrent pneumothorax or pleural effusion that might not yet cause symptoms. Relying on observation alone or waiting for symptoms can miss small recurrences, which can progress if not identified and managed promptly. A post-removal radiograph is the standard step to ensure the patient remains stable and to guide any further treatment if the image shows a recurrence.
