Answer to Question 1

ANS: A
Accounting for 2 to 3 of all cases of COPD, alpha1-antitrypsin deficiency is severely under-recognized by health care providers, but it affects an estimated 100,000 Americans.

Answer to Question 2

ANS: C
Although many risk factors exist for COPD (Box 25-1), the two most common are cigarette smoking (which has been estimated to account for 80 to 90 of all COPD-related deaths) and alpha1-antitrypsin deficiency.
