Partial compensation means that the pH is still abnormal.

Full compensation means that the pH is back to normal.

close The CO2 is normal, so it is providing no compensation here.
close The pH is low (acidotic), so the primary problem is an acidosis of some sort.
close CO2 is the respiratory component.
HCO3- is the metabolic component.
normal: (-2) - 2 mEq/L close

Hint...
This BE is low (acidotic). The pH and BE are both acidotic, so the BE is a primary cause.

normal: 22-26 mEq/L close

Hint...
This HCO3- is low (acidotic). The pH and HCO3- are both acidotic, so the HCO3- is a primary cause.

normal: 35-45 mmHg close

Hint...
This CO2 is normal. The CO2 is not providing any compensation against the low HCO3-.

normal: 7.35-7.45 close

Hint...
This pH is low (acidotic). The other acidotic piece (HCO3- and/or CO2) is the primary cause.
