Math question

  1. 0 Problem: 400 mg of Dopamine in 250 ML, pump running at 23 ML/HR, client weighs 79.5. How many MCG per kilogram per minute is patient receiving? NCLEX IS TOMORROW. I am going over math questions and I can't get this one to come out to the right answer. Can someone please work this out step by step for me. It has been a while since I have done this. Thanks.

    I'm not sure if I have it right but here is what I got:

    (400mg/250ml) x (23ml/hr) = 36.8 mg/hr

    (36.8 mg/hr) x (1000 mcg /1 mg) = 36,800 mcg/hr

    36,800 mcg/hr x (1 hr/60 min) = 613.3 mcg/min

    Then divide that answer by the weight
    (613.3 mcg/ min) / (79.5) = 7.7 or if need a whole number round to 8 ( depending on what question asks for)
    8 mcg/kg/min

    I could be wrong or misread the question. Hope this helps though. Good luck.

    I also assumed the weight you gave was already in kg if it was pounds though I believe the answer would be more like 17.

    Thank you so much. Now I know how to work the problem. That was the right answer. I just couldn't figure out how to get there. I hope I don't get this on my NCLEX but if I do I know how to work it.

    Your welcome. My advice is just take your time. For me anyway I always make sure I cross out the units like ml or mg or whatever when I finish converting. It can be so easy to forget something in a long problem like that. Good luck tomorrow.
