All of the Following Statements Concerning Severe Hyperglycemia's Effect on Serum

All of the following statements concerning severe hyperglycemia's effect on serum Na⁺ levels are true, EXCEPT

A) levels are measured as a concentration, so as water decreases, levels increase.
B) administering a hypertonic saline would help compensate for the decreased Na⁺ levels.
C) as insulin is administered, serum Na⁺ levels will return to normal.
D) the amount of Na⁺ is really unchanged since the water has only changed location and not left the body.
E) the Na⁺ levels would appear decreased as the ICF water leaves for the hyperosmotic ECF.
