Answer to Question 1

ANS: D
If HCO3 is in the normal range in the presence of alkalosis, then the alkalosis probably is of res-piratory origin.

Answer to Question 2

ANS: A
The patient has a compensated metabolic acidosis. This is characterized by a low HCO3, a pH between 7.35 and 7.39, and a low PaCO2. The compensatory response (decreased PaCO2) has restored the pH to the low normal range.
