A patient diagnosed with diabetic ketoacidosis (DKA) has the following laboratory values: arterial pH 7.20; serum glucose 500 mg/dL; positive urine glucose and ketones; serum potassium (K+) 2 mEq/L; serum sodium (Na+) 130 mEq/L. The patient reports that he has been sick with the “flu” for 1 week. What relationship do these values have to his insulin deficiency?


▸ Increased glucose use causes the shift of fluid from the intravascular to the intracellular space.

▸ Decreased glucose use causes fatty acid use, ketogenesis, metabolic acidosis, and osmotic diuresis.

▸ Increased glucose and fatty acids stimulate renal diuresis, electrolyte loss, and metabolic alkalosis.

▸ Decreased glucose use results in protein catabolism, tissue wasting, respiratory acidosis, and electrolyte loss.
