Effect of infusion of hypotonic saline?

Ans. is 'c' i.e., Increased in both ICF and ECFAfter infusion of hyptonic saline causes a decline in plasma osmolality and a shift of water into interstial space (as water moves from higher osmolarity to lower osmolarity), causing decrease in ICF osmolality.This results in shift of water from ECF to ICF.Finally, both ECF and ICF compaments are increased (due to increases water) and osmolality of both compament are decreased.
