Answer to Question 1

ANS: C
Oxygen therapy is the main treatment that improves survival among patients with COPD and pulmonary hypertension, though smoking cessation and lung volume reduction (in selected indi-viduals) may also confer survival benefits in patients with COPD.

Answer to Question 2

ANS: A
Alveolar hypoxia, because of its potent pulmonary vasoconstrictive effect, is probably the most important factor contributing to pulmonary hypertension in patients with COPD. Sustained alve-olar hypoxia causes pulmonary vasoconstriction and eventually medial hypertrophy, fibrosis of the intima, and narrowing of the lumen of the pulmonary blood vessels.
