The infusion of hypertonic saline is most appropriate for severe hyponatremia with seizures or other severe symptoms, as it rapidly increases serum sodium concentrations, reducing cerebral edema. Isotonic saline, though helpful for increasing extracellular fluid volume, would not be as effective in rapidly correcting severe hyponatremia. Fluid restriction is more applicable for mild cases. Potassium chloride would not address hyponatremia and could exacerbate her condition.
