Chose the best answer from the answer options:

1. Blood glucose 500 mg/dL (27.8 mmol/L); arterial blood gases: pH 7.30, PaCo2 50, HCO3– 26.
2.	Blood glucose 400 mg/dL (22.2 mmol/L); arterial blood gases: pH 7.38, PaCo2 40, HCO3– 22.
3.	Blood glucose 450 mg/dL (25.0 mmol/L); arterial blood gases: pH 7.48, PaCo2 39, HCO3– 29.
4.	Blood glucose 350 mg/dL (19.4 mmol/L); arterial blood gases: pH 7.28, PaCo2 30, HCO3– 14.

Answer 1

Ans) 4. Blood glucose 350 mg/dL (19.4 mmol/L); arterial blood gases: pH 7.28, PaCo2 30, HCO3– 14.

Explaination:

- Diabetic ketoacidosis is typically characterized by hyperglycemia over 250 mg/dL, a bicarbonate level less than 18 mEq/L, and a pH less than 7.30, with ketonemia and ketonuria.
