calculating fluids?

Question

I have to do a math problem that requires to calculate fluid. I'm not sure what i did wrong or if i missed a step in this calculation.

The doctor orders 6 mEq of potassium chloride (20 mEq/10 mL) per 250 mL of IV fluids. What volume will you add to a 1 L bag of fluids?

My solution:

6 mEq x 4 = 24 mEq

24 mEq / 20 =1.2 mL

Answer 1

Hi Rosalie H.,

the 1.2 is a scale factor. You still must multiply by the basis volume of the KCl source, namely x 10mL, for 12 mL as your answer.
