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