A. pH 7.25, HCO₃- 19 mEq/L, PaCO₂ 30 mm Hg B. pH 7.30, HCO₃- 26 mEq/L, PaCO₂ 50 mm Hg C. pH 7.50, HCO₃- 20 mEq/L, PaCO₂ 32 mm Hg D. pH 7.55, HCO₃- 30 mEq/L, PaCO₂ 31 mm Hg

Correct Answer is A

Explanation

A. pH 7.25, HCO₃- 19 mEq/L, PaCO₂ 30 mm Hg indicates metabolic acidosis with partial respiratory compensation. This is a common finding in chronic kidney disease due to the kidneys' reduced ability to excrete hydrogen ions and reabsorb bicarbonate.

B. pH 7.30, HCO₃- 26 mEq/L, PaCO₂ 50 mm Hg suggests respiratory acidosis with a normal bicarbonate level, which is not typical for chronic kidney disease.

C. pH 7.50, HCO₃- 20 mEq/L, PaCO₂ 32 mm Hg indicates respiratory alkalosis, which is not characteristic of chronic kidney disease.

D. pH 7.55, HCO₃- 30 mEq/L, PaCO₂ 31 mm Hg indicates metabolic alkalosis, which is also not typical for chronic kidney disease.
