Human red blood cells contain 0.9% sodium chloride as a component of their cytoplasm. What would happen if an IV solution containing 3.5% sodium chloride is introduced into a person? 

• The red blood cell would get bigger and burst.

• The red blood cell would stay the same size.

• The red blood cell would shrink.

• The red blood cell would first loose water and then absorb water.
