Answer:
Both of the regular intravenous solutions administered in medicine, normal saline and lactated Ringer’s solution, are isotonic. Why is this important?
Explanation:
Because the isotonic saline solution has a sodium concentration similar to that of blood.
ISOTONIC SOLUTIONS: The osmolarity of the isotonic fluid approximates the osmolarity of serum plasma. Isotonic fluids are used to hydrate the intravascular compartment in situations of significant fluid loss, such as dehydration, bleeding, etc.
