A 25-yeаr-оld Africаn Americаn man with a 5-day histоry оf nausea and vomiting. He also reported a 2-week history of polyuria (increased urination) and polydipsia (increased thirst) and a 10-lb weight loss. The laboratory data showed an anion gap of 24 and glucose 314mg/dl. ABG results show pH of 7.14, PCO2 30 mmHg, PO2 89 mmHg, and HCO3 8mEq/L. Interpret his ABG results.
