Question

b.         So, if you add that amount of mM glucose in the IV bag, what adjustment do you have to make for the NaCl ?

B.        A physiological saline is just salt in water. Assume your patient needs energy. You will provide it in her IV bag in the form of glucose ( also called dextrose).

a.         The average glucose levels in blood is about 80 mg/deciliter. What is the Molarity of glucose in blood ? ( you will need to figure out what a deciliter is and the MW of glucose…. Express your result in mM)

Explanation / Answer

Molarity = (weight of glucose / molar mass of glucose × volume in ml) × 1000

M= (80 / 1000× 180 × 100)× 1000

M=0.80/180

M=0.0044 = 0.0004 M

1M= 1000 mM

Therefore, 0.0004×1000= 0.4 mM

Molarity is 0.4 mM
