When a person receives intravenous fluids to help build up blood volume, why is it important for the fluid to be isotonic?
What will be an ideal response?
Intravenous fluids must be isotonic to prevent the cells from losing or gaining water. If the solution was hypertonic, the cells of the body would lose water, shrink, and possibly be harmed. On the other hand, the introduction of hypotonic fluid would cause the cells to swell and tissues to rupture.
