(A) The chloride level is within acceptable limits. (B) The sodium level is within acceptable limits. (C) This value indicates hypokalemia, rather than the hyperkalemia that occurs during diabetic ketoacidosis. (D) When diabetic ketoacidosis exists, intracellular dehydration occurs and potassium leaves the cells and enters the vascular system, thus increasing the serum level beyond an acceptable range. When insulin and fluids are administered, cell walls are repaired and potassium is transported back into the cells. Normal serum potassium levels range from 3.5-5.0 mEq/L.
