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
. 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:
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.
