Uncompensated metabolic acidosis

Answer and Explanation

The Correct Answer is C

A. Compensated metabolic acidosis would show a normal pH with a decrease in HCO3- and a decrease in PaCO2.

B. Compensated respiratory acidosis would show a normal pH with an elevated PaCO2 and a compensatory increase in HCO3-.

C. The low pH indicates acidosis, and the elevated PaCO2 suggests that it is respiratory in origin, with the HCO3- remaining normal, indicating no compensation has occurred yet.
