Favorite formulas for drug and IV calculations

[Java Mama]

Hi Everyone,

I am starting my program in 10 days and am still worrying about the math. I've been out of school for a long time and have taken math courses (got an A and a B), but reading my drug calculations book, there are so many different ways to figure out the solutions. If you could give me some examples of the formulas you prefer and why, I'd really appreciate it. Is there one over another that you would have a less-likely chance making a medication error? That is my biggest fear. I know there is no room for error when it comes to giving medications. Thanks. :)

did you use a book to teach you the dimentional analysis method? I just ordered "calculate with confidence" and am hoping it has enough of the dimentional analysis method because I hear about this one the most.

No I did not use a book. I had an awesome instructor who is also the author of this med math book - honestly though, she was so thorough at explaining things, I barely even cracked open the book.

I like the ratio porportion better than dimensional analysis. That way seems easier and sticks in my brain. You have to do what works best for you.

I learned dimensional analysis in Highschool chem! So of course that's what I prefer! It's sooooo easy to understand and sooooooo hard to mess up.

Mangopeach,

What luck that your teacher is the author of a dosage calculation book!!!
