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

6. I guess we've mixed up some decimal points, huh?!?!
hehehe:chuckle
7. 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!!!
8. ahhh ok. So ladies..did you work it out? LOL

I'll tell you what. I hate math so I envy you being able to even Attempt to work it out.:chuckle

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

I keep getting the 4000 mcg/ml

Oh well... sorry about the decimal confusion!
10. 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.
11. it's 4000!!!
12. ITA - 4000 mcg per ml concentration.
13. The first line:

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

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.)
14. 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!)
