The nurse is caring for a diabetic patient in renal failure who is in metabolic acidosis. Which laboratory findings are consistent with metabolic acidosis?

pH 7.35, PaCO2 40 mm Hg, HCO3-25 mEq/L

pH 7.32, PaCO2 47 mm Hg. HCO3-23 mEq/L

pH 7.3, PaCO2 36 mm Hg. HCO3- 19 mEq/L

pH 7.5, PaCO2 35 mm Hg, HCO3- 35 mEq/L

Answer and Explanation

The Correct Answer is C

A.   pH 7.35, PaCO2 40 mm Hg, HCO3-25 mEq/L: This is within normal ranges and does not indicate acidosis.
B.   pH 7.32, PaCO2 47 mm Hg. HCO3-23 mEq/L: This indicates respiratory acidosis, not metabolic.
C.   pH 7.3, PaCO2 36 mm Hg. HCO3- 19 mEq/L: This indicates metabolic acidosis. The pH is low (acidic), and the HCO3- (bicarbonate) is decreased. The PaCO2 is within normal limits, indicating the respiratory system is compensating for the metabolic acidosis.
D.   pH 7.5, PaCO2 35 mm Hg, HCO3- 35 mEq/L: This indicates alkalosis, not acidosis.
