Dosage calculations

[stephenebr]

Hello everyone,

Please feel free to bump this if this isn't the appropriate section. I am starting the nursing program in a few weeks, though excited I am a bit concerned about dosage calculations. I have a decent grasp on math but am not fluent in this. I have been working on some problems through a dosage calculations book independently..to give you an idea of the scope we may go into I will be in an LPN program so I am not sure of the extent of the math. One clinical instructor stated that we will be using D over H x V formula and that is it. Nothing more, nothing less..maybe I am being a little neurotic about it but they do want accuracy, 75% in PN1 and 85% in PN2. Is there any helpful tips or resources or advice anyone can give me? I am able to work out some problems in the dosage book comfortably though they are not always 100%.. Thanks a bunch..

Stephen.

Good day:

I found DosageHelp.com - Helping Nursing Students Learn Dosage Calculations to be extremely helpful. That site mainly uses the d/h * q method. I also recommend learning at least two methods to solve the dosage calculation problems. I strongly recommend the formula method (which most of the professors use and recommend) as well as dimensional analysis (also known as unit math).

The reason to learn at least two methods is the second method can be used to cross check the fist method. Since both methods should get the same answer, it is a solid method for double checking vs. re-doing the work to get the same answer (which can be error prone).

is a great video on how to learn dimensional analysis.

Thank you.

Thanks so much! -- I came across dosage help previously but was not sure about the content. I'll look more into it and utilize it. Thanks.
