Answer to Question 1

C
Fibrocalcific pleural plaques, bronchospasm, and excessive bronchial secretions are among the pathologic and structural changes associated with asbestosis.

Answer to Question 2

B
Peripheral shunting decreases the C(a-v)O2 because less oxygen is extracted by the tissues. All of the other listed options increase oxygen extraction and so will increase the C(a-v)O2.
