    There are 1000 mcg in 1mg

    Dobutamine 1gram = 1000 x 100 = 100,000 mcg
    Dobutamine 100,000 mcg in 250 mls

    Dobutamine 100,000 mcg in 250 mls Now divide both mcg & mls by 250 to simplify=

    Dobutamine 400mcg in 1 ml

    It is easy to jumble our brain cells when we have too many zeros and decimals!!!

    I just noticed you are in Rochester - I grew up in Osseo - near MPLS !!!
    Too cold for me!! I am a southern girl now!!!

    That's really funny you say that you're from here... I am actually from New Orleans and just moved up here. Working at Mayo...
    That town sounds familar but I'm still not sure about the area. How far away is Osseo?
    So I guess we traded places

    Anyway... still not sure about this problem...

    I keep getting the 4000 mcg/ml

    Oh well... sorry about the decimal confusion!

    Osseo is just a little north of MPLS.
    I have lived in Virginia for about 20 years now -
    I love the heat and the summers here - and the mild winters.

    ITA - 4000 mcg per ml concentration.

    The first line:

    Dobutamine, 1 gram= 1000 x 100 = 100,000 mcg

    should read:

    Dobutamine, 1 gram= 1000 x 1000 = 1,000,000 mcg

    That's why the correct answer is 4000, not 400. (I always like to know what went wrong.)

    I am hardly a math whiz...so I'm not posting an answer, but I just wanted to let you all know that seeing a formula like that kind of gives me an idea of what I'm in for!

    :uhoh21:

    Is it just all about conversions? I rremember learning some of that in high school (20+yrs ago!)
