Answer to Question 1

ANS: D
Ventilation-perfusion () imbalances are the most common cause of hypoxemia in patients with lung disease.

Answer to Question 2

ANS: C
Oxygen delivery (O2) to the tissues is a function of arterial O2 content (CaO2) times cardiac out-put (t):
O2 = CaO2  t
If arterial O2 content falls an increased cardiac output will compensate.
