Multiple Choice

Why do solutions for injection or infusion into people with low blood volume normally contain 150 mM NaCl?

A) This is a hypotonic solution,which will cause water movement into dehydrated blood cells.
B) This is an isotonic solution,and the water in it will follow Na and Cl into the intracellular fluid compartment.
C) This is a hypertonic solution,which will raise the blood volume and pressure more rapidly than an isotonic solution would.
D) This is an isotonic solution,and NaCl will keep the added volume in the extracellular fluid compartment.
E) NaCl are penetrating solutes,which will get them more quickly into blood cells to increase their volume.
