What concentration of sodium chloride is the normal saline that is isotonic with blood cells?
A0.09% (mass/volume)
B9% (mass/volume)
C0.9% (mass/volume)
D1.8% (mass/volume)
Answer & Solution
Correct answer: C. 0.9% (mass/volume)
Normal saline at 0.9 percent mass by volume matches the osmotic pressure of blood cell fluid.
