ABG Practice Questions With Verified Answers. pH 7.18 PaCO2 38 mm Hg PaO2 70 mm Hg HCO3- 15 mEq/L - answerMetabolic acidosis pH is low. PaCO2 is normal. HCO3− is low. By using the ROME mnemonic, the metabolic component (HCO3− ) is going in the same direction as the pH—thus the patient has metabolic acidosis. Because the CO2 is normal, there is no compensation. pH 7.60 PaCO2 30 mm Hg PaO2 60 mm Hg HCO3- 22 mEq/L - answerRespiratory alkalosis pH is high. PaCO2 is low. HCO3− is normal. By using the ROME mnemonic, the respiratory component (PaCO2) is going in the opposite direction as the pH—thus the patient has respiratory alkalosis. Because the HCO3− is normal, there is no compensation. pH 7.58 PaCO2 35 mm Hg PaO2 75 mm Hg HCO3- 50 mEq/L - answerMetabolic alk
