Answer to Question 1

ANS: A
Full obstruction, or mucus plugging, can result in atelectasis and impaired oxygenation due to shunting.

Answer to Question 2

ANS: B
By restricting airflow, partial obstruction can increase the work of breathing and lead to air trap-ping, overdistention, and ventilation/perfusion () imbalances.
