That's a good question and I'm wondering the same thing!! Lol I took a med math class as a pre req for the lvn program and was not allowed to use a calculator. But now I'm starting the BSN this fall and have no idea if a calculator can be used. But I'm still refreshing up on my long division, it can't hurt but it sure would be a whole lot nicer to use a calculator.
I would not spend a second worrying about this right now. Your instructor will tell you exactly what they expect. If you can understand the concept of dimensional analysis, which it sounds like you do, don't worry about it. This is such a small part of your education. There are other, more important things to be focusing on before school starts. Like earning money and nursing fundamentals.
This website provides a dosage calculations tutorial, complete with explanations and examples, to help nursing students prepare for a medication exam.

Thanks guys :-). I know I shouldn't worry too much about it right now but honestly math is not my strong subject and I would so much rather spend 20 minutes on it here and there over the summer than end up stressing out about it once school starts :-)
The kind of math you need for nursing is super super basic. Just make sure your answer makes sense, and that your conversions are correct. Know how to go from grams to mg, etc. And know that the DOSE is the amount of medication (mg) NOT the volume (mL).
My school has started providing basic calculators, you can't use your own (you could store info in the memory, etc., if you brought your own).
Your initial math test won't have IV drip rates on it, in all likelihood. It's going to be basic stuff like, "The order is for 550mg of
You need to be aware of things like converting mcg/mg and realizing that 1mg in 5mL is actually 200mcg/mL.
As you progress further in the program, you'll be given things like the patient's weight in lbs and a dosage per kg of body weight, so you'll need to convert pounds to kg, then compute the ordered dose times kg to determine the total dose ordered, then compute how much drug to be administered based on what is available. A lot of my fellow students get flustered by these multi-step problems, but if you look at it as three separate, simple problems instead, it's not as intimidating. Converting lbs to kg is no big deal. Multiplying ordered dose per kg by # of kg is no big deal. Computing amount to administer based on a known dose and a known medication strength is no big deal.
Don't let it intimidate you -- it is all basic math that any fifth-grade student can do -- it's just multiplication and division with fancy-sounding names tossed in to try to throw you off. Just be aware that the longer you go in the program, the more unnecessary crap they'll throw in to try to confuse you. If the order is for 500mg of
Take a deep breath. Figure out what they're asking for. Then find the info you need in order to calculate the answer. Ignore the other crap.
We have math test at the beginning of each semester. You have to get 90 in your sophmore and junior year, and 100 in your senior year. It is very basic math, so no need to worry. Just pay attention to the units they give and they ask, also rounding the numbers ( always round the IV pump to the nearest whole number ). Believe me, when you're dealing with classes like patho or pharm, you won't even care to study for the math test. Good luck!!!

The nursing school I am (hopefully) starting in the Fall has a dosage math test in the first few weeks that you have to pass. From what I've read all schools seem to do this so I was hoping that you guys could give me more of an idea on what to expect.
I have started working through a dosage calculations book using dimensional analysis and I'm feeling pretty confident. The book is now starting into IV meds which is getting a little tricker. For your first math test do they test you on medication dosage questions or will they also look at IV's and drop factor questions too?
Also, do most places let you use a calculator for your first math test or should I start brushing up on my long division?
Thanks,
