Acid base - goodman - ArchivalUser - 08-29-2017
When has full acid-base compensation occurred?
a. When PaCO2 and HCO3- go in opposite directions
b. When PaCO2 and HCO3- go in the same direction
c. When pH remains on the alkaline or acid side close to the normal range
d. When pH is restored to the normal range even though pH remains on the alkaline or acid side of the range

When has partial acid-base compensation occurred?
a. When PaCO2 and HCO3- go in opposite directions
b. When PaCO2 and HCO3- go in the same direction
c. When pH is within the normal range
d. When the noncausative component (either PaCO2 or HCO3-) is also abnormal in a way that brings the pH back toward the normal range
