Answer to Question 1

ANS: A
The partial pressure of carbon dioxide in the alveoli and blood is directly proportional to its pro-duction (CO2) and inversely proportional to its rate of removal by alveolar ventilation (VA).

Answer to Question 2

ANS: D
Ventilation that does not meet metabolic needs (resulting in respiratory acidosis) is termed hypoventilation. Hypoventilation is indicated by the presence of an elevated PaCO2.
