Welcome to the second edition of our dosage calculations book!

Are you a nursing student, or nurse, who wants to learn a few simple methods of solving dosage
calculations without a bunch of formulas?

Would you like to raise your hand in your dosage calculation class, after the instructor explains a
complicated formula, and ask to approach the white board to show the class a much simpler method?

Do you want to go on your clinicals knowing that you have a solid foundation in dosage calculations?

Do you want to walk into your Nursing Calculations Class on the first day knowing that you can ace all
the tests before the course begins?
