HELP!!!!!!!!!!!!!!!!!!!!!!!Nursing Math

Published

Specializes in rehab, dementia.

Can anyone recommend a good nursing math calculations website. I am having a rough time. I got so upset in my calculations class today, that I cried:o. I guess ns is getting the best of me. All my instructor kept saying to us is "this is easy".....at that point, I just wanted to pack my bags and books and go home.

I guess I was emotional from an A/P exam that I took later today and it was difficult.

Anyway, please help. This is the second week of math calculations and I gotta score a 90 to pass the class!:uhoh21:

Thanks

Beth,

Thanks so much for catching my request. I will check out the site.

Thanks again. I'll be posting again, if I have any questions. Oh, I asked one of the site managers for this forum if they can establish a math site only...for calculations. So we'll see!

Thanks,

stuff

there is a sticky thread for dosage calculations on this forum that has some links listed in the beginning posts and towards the end has lots of examples of problems that are worked out

the accd website that you were given by beth66335 is an excellent tutorial for medical math calculations.

I sympathises with you,I feel the same about Med calc exams,we have to get 100 percent!!!!.the pressure is huge,and if you forget to write the formula or something silly,and still get the right answer you will still fail.It is awful and nerve racking.

Don't ya hate it when they say it is easy and it isn't for you!

I tutored a fellow student who could not get an 80% in the math test after 2 attempts. I showed her the dimensional analysis technique and she passed with 91% on her third and last attempt. So look into that method, I find it the easiest by far.

the nurse procalc booklet with cd is very helpful. i don't know any websites for nurse math, but i might interest you with my short formulas.arrggh it's hard to type formulas here.

probs.

pills/powder/ampules/vials: dose ordered (d) divide drug on hand (h) then multiply volume (v/ml) this formula applies to insulin units too

gtt/mins: gtt factor(gf) divide #minutes(m) then multiply volume (v/ml)

make sure you understand the question first and convert what needs to be converted.

This page http://www.bruteforcestudyguide.com/learndrugcalculation.html has a calculator that shows you the steps to calculate the value.

Hope this helps.:nuke:

i love those formulas they really help me in my pharm class i remember the dosage formula by a little brain tag... what is ordered is more important than what you have so it goes on top...then multiply by the milli's. it helps me to brain tag things... good luck

does anyone know the formulation to the following math prolem. this is one of my courses math questions and i cannot figure out how to set this up with the numbers provided. any help would be greatly appreciated.

dextrose 5% in water with epinephrine is infusing at a rate of 120 ml per hour. the iv solution was prepared by adding 2 mg of epinephrine to dextrose 5% in water. the final solution contained a total volume of 250 ml. how many mg are infusing per minute? round to the thousandth and do not write the units.

120 ml/1 hour
(rate of infusion)
x 2mg/250 ml
(dose on hand)
x 1 hour/60 minutes
(conversion factor)
=
0.016 mg/minute
(dose desired)

this could also be expressed as 16 mcg/minute.
