A patient was involved a serious accident and lost a large quantity of blood. In an attempt to replenish body fluids, distilled waterequal to the volume of blood lostis added to the blood directly via one of his veins.

What will be the most probable result of this transfusion?

The correct answer will be - The blood sample will become hypotonic as a result of which RBC will swell.

Explanation:

In the given question, water was given to the patient who lost his blood in the accident.

The addition of an equal amount of water could have caused the blood solution to become hypotonic that is with low salt concentration and high water potential.

Since the solution is hypotonic and the concentration of water is high in blood than in blood cell, the water will move inside the Red blood cell through diffusion and the cell will swell and could burst. This would lead to the death of the patient.

Thus, the blood sample will become hypotonic as a result of which RBC will swell is the correct answer.
