 Options:  <1> pH 7.30, HCO3 18 mEq / L, Cl 116 mg / dL, because metabolic acidosis with normal anion gap is characteristic. <2> pH 7.46, HCO3 18 mEq / L, Cl 116 mg / dL, because hyperchloremic metabolic alkalosis is characteristic. <3> pH 7.456, HCO3 18 mEq / L, Cl 100 mg / dL, because metabolic acidosis with increased anion gap is characteristic. <4> pH 7.46, HCO3 30 mEq / L, Cl 90 mg / dL, because metabolic alkalosis with normal anion gap is characteristic. <5> pH 7.45, HCO3 23 mEq / L, Cl 100 mg / dL, because metabolic alkalosis with normal anion gap is characteristic.
