Q

Isotonicity: Solving for amount of NaCl needed to prepare an isotonic solution

A

Step 1: calculate total amount of NaCl needed to make final volume by multiplying 0.9% NS by desired volume

Step 2: Calculate the amount of NaCl represented by the drug. To do this, multiply the total drug amount (mg or g) by the E value.

Step 3: subtract step 2 from step 1 to get your answer
