Given the following arterial blood-gas results, which choice best describes the expected base excess/deficit and total CO₂ results for the sample?
PH = 7.32
PCO₂ = 65 mm Hg
HCO₃ = 24 mEq/L

Given the pH, a base deficit (below normal) would be expected.The total CO₂ is determined using the equation: TCO₂ = HCO₃ + αlogpCO₂ TCO₂ = 24 mEq/L + 0.031 mmol/mm Hg•L × 65 mmHg TCO₂ = 26 mmol/L
The normal reference interval for arterial total CO₂ is 23 - 27 mmol/L.Thus a base deficit (below normal) and a normal TCO₂ is expected to accompany the laboratory data provided in the question.
