hello! i am re-entering the nursing field and trying to brush up on my math. can anyone help me solve this problem using dimensional analysis? i have been working on it forever!!!!
[color=#0080c0]for the client whose weight is 130 lbs and has dopamine ordered at 8 mcg/kg/min, what rate should the infusion pump be set for a solution of 400 mg dopamine in 250 ml d5w?
So, first you want to know mcg/min. 130 pounds = 59.09 kg
So, your order is for 472.7mcg/min or 0.473mg/min or 28.3mg/hour (60 minutes)
Then you want to know how many mg are in each ml.
So now you know there are 1.6mg/ml and 28.3mg/hour
How many ml/hour do you need to get this dose? In other words, how many ml will get you the 28.3mg?
28.2/1.6= 17.7 ml/hr

8 mcg X 130 lb X 1kg/2.2 lb X 250 ml/400mg X 1mg/1000mcg X 60min/1hr
