Hi Gail
this is what i would have answered.

Symptoms: Vomiting

Blood gas
venous sample:
PH 7.23 – = Acidemia
PCO2 30mm/Hg – low – alkalosis
HCO3 13mmol/L – low acidosis
lactate of 4.3mmol/L. hyperlactatemia

Answer-
Metabolic acidosis with a compensated respiratory alkalosis

Significance of the Lactate level? the high lactate can either mean there is an lactic acidosis or poor tissue perfusion
Significance of the HCO3 Levels? the significance of the HCO3 means there is a metabolic cause to the acidemia
