Which of the Following Best Describes Normal Saline

Question

Which of the following best describes normal saline?
A) Radioactive
B) Hemolytic to red blood cells
C) Isotonic
D) Crenating to red blood cells

Accepted Answer

Normal saline is an isotonic solution, meaning it has the same concentration of solutes as the fluid inside of cells. It is commonly used as a physiological saline solution and does not cause hemolysis (breakdown of red blood cells) or crenation (shriveling of red blood cells). It is also not radioactive.
