Answer to Question 1

ANS: C
Patients who have had one pneumothorax are more likely than the general population to have a second. The recurrence rate is greater than 30 among patients with primary spontaneous pneu-mothorax and approximately 40 among patients with secondary spontaneous pneumothorax. These high recurrence rates indicate that prevention of recurrence of pneumothorax should be undertaken, particularly for patients in whom pneumothorax may be life threatening. Preventing recurrence involves production of adhesions between the parietal and the visceral pleura in the involved area and is termed pleurodesis.

Answer to Question 2

ANS: C
CHF is the most common cause of pleural effusions in clinical practice. The effusions can be massive, filling the entire hemithorax and compressing the lung. More commonly, they are small and bilateral.
