AB Measurement  of  electrolyte-free  water  clearance  is  extremely  useful  in  understanding  the  pathophysiology  of  hyponatremia  and  hypernatremia.Treatment  of  hyponatremia  should  be  guided  by  the  degree  of  symptomatology,  rather  than  the  magnitude  of  the  hyponatremia  per  se.Hyperkalemia  should  be  treated  emergently  if  typical  electrocardiographic  (ECG)  changes  are  present;  hence,  ECG  monitoring  is  indispensable  in  this  settingHypocalcemia  need  only  be  treated  urgently  if  it  is  symptomatic.Severe  hyperphosphatemia  is  seen  in  the  setting  of  renal  failure  and/or  massive  cell  lysis.Total  body  phosphate  stores  may  be  significantly  reduced  and  produce  organ  dysfunction  even  in  the  face  of  normal  or  minimally  decreased  serum  levels;  if  suspicion  for  a  depleted  state  exists,  treatment  should  be  given.Severe  hypomagnesemia  may  have  significant  consequences  itself,  including  cardiac  arrhythmias  and  muscle  weakness;  lesser  degrees  of  hypomagnesemia  often  accompany  hypokalemia  and  hypocalcemia  and  correction  of  the  magnesium  deficit  facilitates  correction  of  the  other  electrolyte  abnormalities.
