Dosage Help

Hello. I am working on a pharmacology equation and need some help. The question is Patient is receiving 4mcg/kg/min of epinephrine. Patient is 60kg and is receiving it over 60 min. How much epinephrine does the patient receive?

I multiplied 4mcg/kg/min by her weight 60kg. From there I'm lost. I'm sorry I sound so stupid. Any help please?

Thanks

    are you saying that you did 4 x 60kg = 240? If this is where you stopped then all you would need is to multiply 240mcg/min by the total time the patient is receiving the infusion to find the total mcg dose that would be infused.

    OK so you have figured out how much she is getting per minute. So how much will the patient get in an hour?

    So if the patient is getting 240mcg/min and there is 60 min/hr...how many mcg/hr is there?

    240mcg/min x 60/min = ______mcg/hour

    That's what I did. But the teacher put 9mg as the answer? *** that can't be right. Right?

    No, it isn't. What do you think the answer is?

    Thanks for everyone's help. So I did 4mcg/kg/min X 60kg = 240mcg/min

    I converted 240mcg to 0.24mg/min

    0.24mg/min X 60mins = 14.4mg/min

    That looks right. You need to ask the teacher where the 9 mg came from.

    Just one thing. The answer is not 14.4 mg/min, it's just 14.4 mg. When you multiply 0.24 mg/min x 60 min, the minutes cancel each other out and you are left with the dose in mg.

    Yep. See up above when you were starting with "0.24 mg per minute"? You can't say that AND 14.4mg per minute, can you? :)
