No...it is not "normal" for EMT-Bs to be learning this. Of course you will learn these calculations in an LVN program.
Your formula is basic, but it varies depending on what one is solving for. One must obviously know the volume to be infused, the time that the medication is to be deliverd over, and the drip rate factor (i.e. micro vs. macro).
Give me one of your problems and I will solve it for you step by step so you can see it all mapped out (I would try and make one up but I can't think right now, as it is 0215 and I'm beat).
