Answer to Question 1

ANS: A
The mechanisms of airflow obstruction in COPD include inflammation and obstruction of small airways (<2 diameter).

Answer to Question 2

ANS: D
Treatment with methylxanthines offers little additional bronchodilation in patients on inhaled bronchodilators, and generally it is reserved for patients with debilitating symptoms from stable COPD, despite optimal inhaled bronchodilator therapy.
