<prompt> A child presents with acute diarrhea with signs of dehydration; On investigation, Na 125 mEqL, K 3 meqL, HCO3- 16 mEqL and pH is 7.23. IV Fluid to be given is?Normal saline3 salineN2 saline 10 dextroseN3 saline 5 dextrose  <response>: Hyponatremic dehydration is treated by correction of intravascular volume with isotonic fluid NS or LR. An overly rapid 12 mEqL over the first 24 hr or overcorrection of serum sodium concentration 135 mEqL is associated with an increased risk of central pontine myelinolysis.
