ANS: B
The most common indications for a chest tube are pneumothorax (air in the pleural space) and empyema (pus in the pleural space), although chest tubes may also be used to drain blood (hemothorax) or fluid (hydrothorax) or to install a sealant (e.g., the antibiotic doxycycline) to achieve closure of the pleural space, thereby preventing recurrent pneumothorax or hydrothorax.
