Answer to Question 1

D
Alveolar-capillary membrane function is measured by the pulmonary diffusion capacity of the carbon monoxide test. A very small amount of carbon monoxide (CO) is inhaled by the patient to perform the test. But the CO level is not measured in the blood, and CO is not removed from the blood.

Answer to Question 2

C
Chest radiology findings will include, but are not limited to, retraction of lung segments secondary to fibrosis and scarring and right-sided heart enlargement due to cor pulmonale.
