# Seriousely,do you even use algebraic equations ? - page 3

Since you are only as strong as your weakest link,I would like to know if you use algebra in your daily routine.If you do use it, then to what degree and how is it applied? I know how to do the... Read More

1. Quote from pnurseuwm
Calc is usually just a weed-out class.... give me algebra ANY day!
In nursing prereqs, algebra is often a weed out class.

In fact, it almost weeded me out.
2. Someone asked for an example of a math problem. I work in an ER...our Fentanyl comes in 100mcg/2cc vials. Order is to give: 50mcg IVP of Fentanyl:

So...you have 100mcg/2cc = 50mcg/x (what you want to give)

You then multiple the 50mcg X 2cc = 100 and divide by 100 to get 1cc which is the volume you need to give. Does that help?? In ICU/ER you also have drips based on kg. For instance: Dopamine is usually started at 5-10mcg/kg/min so you factor in the concentration of the drug and go from there.

thanks for the example! i still have a long way off before nursing school (doing bsn prereqs while i wait) but i am in college algebra currently and just needed to see if the algebra you guys are using is worse than this class.
