Which is the correct interpretation of the following values: pH = 7.36; PaCO2 = 22 mm Hg; and HCO3– = 12 mEq/L?
a. Combined alkalosis c. Compensated res-piratory alkalosis
b. Combined acidosis d. Compensated met-abolic acidosis
ANS: D
The pH of 7.36 is a compensated acidosis; any value greater than 7.35 is indicative of acidosis. A PaCO2 of 22 mm Hg is indicative of a respiratory alkalosis and a HCO3– of 12 mEq/L represents a metabolic acidosis. Therefore, the interpretation is a compensated metabolic acidosis.
