Question 1

Why is it critically important for large volume parenteral (LVP) solutions, administered intravenously, to be isotonic with blood plasma?

Accepted Answer

C. To avoid hemolysis or crenation of red blood cells. — Isotonicity ensures that the osmotic pressure of the LVP solution matches that of blood plasma. Administering hypotonic solutions can cause red blood cells to swell and lyse (hemolysis), while hypertonic solutions can cause them to shrink (crenation), both leading to serious adverse effects. Maintaining isotonicity is crucial for patient safety and physiological compatibility.
