Answer to Question 1

ANS: D
Among the available treatments for COPD, supplemental oxygen is important because, like smoking cessation and lung-volume reduction surgery in selected individuals (see below), it can prolong survival. Box 23-2 reviews the indications for supplemental oxygen, and Figure 23-6 shows the results of the American Nocturnal Oxygen Therapy Trial and the British Medical Re-search Council Trial of Domiciliary Oxygen, 1980-1981. Survival was improved when eligible patients used supplemental oxygen for as close to 24 hr as possible and that survival improved less for those using oxygen only 15 hr/day.

Answer to Question 2

ANS: A
Comprehensive pulmonary rehabilitation is an additional important strategy for improving func-tional status. Indeed, randomized controlled trials show that a pulmonary rehabilitation program including education and a progressive exercise program can enhance exercise capacity, even though lung function and survival are not improved.
