The ABG results show a pH within normal limits, a decreased PaCO2 (indicating hyperventilation or respiratory alkalosis), and a decreased HCO3- (indicating a primary metabolic acidosis). The primary disorder is metabolic acidosis because the primary change is in the bicarbonate level (HCO3-), which is decreased.
