Answer to Question 1

ANS: C
Parapneumonic effusions are common causes of persistent fever among ICU patients with pneu-monia. Sampling by thoracentesis is commonly performed to exclude empyema. Pleural fluid drainage can improve ventilation if the fluid volume is large.

Answer to Question 2

ANS: A
Lymphatic obstruction within the mediastinum causes poor pleural fluid egress from the pleural space, although the pleural space is otherwise normal. The most common condition that causes this abnormality is cancer that metastasizes to the mediastinum.
