Answer to Question 1

ANS: C
A high PaCO2 increases dissolved CO2, lowering the pH:
pH HCO3/PaCO2
where means decreased, means no change, and means increased. Respiratory disturbances caus-ing acidemia are called respiratory acidosis.

Answer to Question 2

ANS: B
When any primary acid-base defect occurs, the body immediately initiates a compensatory re-sponse.
