I recommend an exercise book that you can practice with. They are at the larger chain book stores. Also, find out if there are tutors available. There are only a few problems related to meds. You will use the same ones over and over. Once you get those down you will be fine. Also, carry a "cheat sheet" with you when you work!

I struggled with math when I was in nursing school too. I found a book called "Math for Meds". In it was a formula that I still use today. My instructors tried to teach me four different methods that I could not grasp. After learning this method, I have never had trouble again. Hope it works for you.

Take the medication dose ordered divided by the dose available and then multiplied by the dose concentration. Example: Doctor orders Morphine 2 mg IVP. Morphine available in 5 mg/ml.

2mg/5mg x 1ml = 0.4ml to be given.

Example: Doctor orders Valium 2mg IVP. Valium avaliable in 10mg/2ml.

2mg/10mg x 2ml = 0.4ml to be given.

Hope that helps.

I also recommend buying a clipboard with a lot of this useful info pre-printed on it's face. Always handy when you have a brain-fart.

But nothing beats practice.

Practice. Practice. Practice. Practice, till it becomes second nature.

Pretty soon you'll be doing it in your head

my school required we have "Math for Meds" which is a soft cover work bool that you can do on your own and it is very good.
