Can you solve this mcg to mg conversion?

[Emergent]

I was working at my Per Diem job yesterday. One of the acute care nurses came to me, baffled by an order for Fentanyl that read 100mcg/2ml give 0.025 to 0.05 mg. First of all, I think that's a dumb way for pharmacy to transcribe the order. But, nevertheless, I couldn't get this fellow to understand how much to give. He told me that he is usually good at math, but I kind of doubt it. I diplomatically walked him through it several times, not giving any hint that I thought he should know this. It's important for us nurses to be able to ask our co-workers to double check without them rolling their eyes.

So, allnurses cohorts, is this nursing 101 or is this a confusing order? Can you figure out how many ml to give?

Thank goodness! I was wondering if I was really bad at math when I saw the post and thought I knew the dose then saw I was off by a factor of ten. Glad to read it was edited.

EEEK! 5-10 mls? I think not!

No kidding! My reaction exactly!
