[sociallocker]Correct asnwer is F. Hyperkalemia from massive tissue or cellular breakdown has many causes. Hypokalemia from cell production is rare. When replacing B12 and Folate, particularly if there is pancytopenia, cells in the marrow are produced so rapidly that the marrow packages up all the potassium, lowering the serum level.
