What would happen if the nurse used distilled water instead? a. You would become hydrated more quickly and be much healthier. b. The distilled water solution would be hypertonic to your blood cells, so they would lose water and crenate. c. The distilled water solution would be isotonic to your cells, so nothing would happen.
