Not a lot of math. For a few of the exams, you might have some simple multiplication or division, but nothing more complex than that.

You'll have to know how to do drug dosage calculations, but for the Nursing Concepts tests, there is a calculator on the computer that you can use during your test. You'll just have to know simple multiplication or division to arrive at the correct answer, as Eric said. :)

As Lunah said, there isn't that much math involved. The only one I believe there was math was on NC2, which had IV drip rates and I also believe NC1 had some basic drug dose calculations under medication safety. Here are some basic formulas:

For IV drip rate: rate to be infused X the IV drop admstration set, divided by the number of minutes. For example: the order states to infuse 100 ml per hour on a 10gtt set: 100ml X 10gtt / 60min= 16.666 gtt per minute, you can round it to either 16 or 17.

To figure out a drug dose, take the ordered dose, divide it by the dose on hand and multiply it by the number of pills or the ml's in a vial. For example, if you were ordered to give 1000mg of Tylenol and it were 500mg in each tablet, you could figure it out in your head that it is two tablets, but here is the formula: 1000mg / 500mg X 1= 2

Another example: the order reads 35mg diphenhydramine IV push. It is supplied as 50mg in one ml. 35 / 50 X 1= 0.7ml.

Hope this helps.
