Answer to Question 1

ANS: D
Metabolic acidosis can occur in one of the following two ways: (1) fixed (nonvolatile) acid ac-cumulation in the blood or (2) an excessive loss of HCO3 from the body.

Answer to Question 2

ANS: B
The kidneys compensate for respiratory alkalosis by excreting HCO3 in the urine (bicarbonate diuresis; see Figure 14-3).
