mEq calculation

Question

Order 20mEq /L of KCL needs to be added to a 1L fluid bag

on hand 20 ml KCL bottle with a concentration of 2mEq/L

how much KCL do you draw up to add to the 1L fluid bag

Answer 1

Are you sure you don't have these solutions reversed? You cannot prepare a 20 mEq/L solution from one that is 2 mEq/L. You can, however, prepare a 2 mEq/L solution from one that is 20 mEq/L.
