A man with diabetic ketoacidosis (DKA) has the following lab values: arterial pH 7.20; serum glucose 500 mg/dL; urine glucose and ketones positive; serum K+ 2 mEq/L; serum Na+ 130 mEq/L. He reports that he has been sick with the "flu" for 1 wk. What do you suspect is his problem?
decreased glucose use
- this causes increase in fatty acid use, ketogenesis, metabolic acidosis, and osmotic diuresis all of which he has.
