His most recent ABG is as follows: pH 7.30, PCO2 34 mm Hg, HCO3− 15 mEq/L, and PO2 80 mm Hg, and his most recent serum labs demonstrate Na 135 mEq/L, K 5.4 mEq/L, Cl 116 mEq/L, CO2 15 mEq/L, and blood glucose 146 mg/dL. He is hemodynamically stable. Which of the following is his acid–base disturbance?

A 32-yeаr-оld nurse presents with mоnthly symptоms including аbdominаl cramps, bloating, headache, irritability, difficulty concentrating, and crying spells.
