Answer:
The patient's red blood cells will swell and possibly burst because the blood has become hypotonic compared to the cells.
Step-by-step explanation:
Distilled water is water obtained through the distillation process. Water distillation consists of evaporation followed by condensation (return to liquid state) of water. This process provides the separation of a quantity of salts present in ordinary water, also called mineral water. In other words, distilled water is an extremely low salt water and this makes this water unfit for use in the case shown in the above question.
If distilled water is used as a substitute for the patient's lost blood and injected directly into their veins, the patient's red blood cells will swell and possibly explode because they have lost salts trying to balance the concentration of salts with the distilled water.
