    1. Order reads infuse Epinephrine @ 30ml/hr. The solution available is 2mg of Epi in 250ml D5W Calculate the following
    a. Mg/hr b. mcg/hr c. mcg/min

    2. A Nitro Drip is infusing at 3ml/hr. The solution avail is 50mg/250ml Calculate mcg/hr and mcg/min. I know this its 5mcg per hr but the problem is how do you get there. its something I need to review for myself. Somebody pls help.

    This smells like homework to me. You should recheck your answer for #2 it's a lot more than 5mcg/hr

    You have 2mg in 250cc, therefore how many mcgs are in a mg? How many min in a hr? How many cc's in hr? How many in the solution.... It is basic math. It is not calculus.

    You are making it too hard.
    Your answer to #2 is wrong. Try again. Ask a student to help. You are going to slap your forehead when you get the answer.

    Is this a nursing homework or nursing boards question??? Isn't school out? If you are currently working in a unit they have titration sheets to use. No time for math class when a patient is crashing!!

    Aah! Drug calcs!! Know the math before you kill your patients-yeah right! With all the smart infusion pumps, who needs drug calcs?
    1. a. If 250ml of D5W contains 2mg, it follows therefore that 30ml/hr will have 0.24mg/hr i.e (2mg x 30ml/hr) /250ml.
    b. Now we know that 0.24mg/hr = 240mcg/hr i.e If 1mg = 1000mcg therefore 0.24mg/hr = 240mcg/hr
    c. We know from b above that epi is running at 240mcg/hr = 4mcg/min

    2. Use same logic as above and you will arrive at 0.6mg/hr and 10mcg/min.

    Goodluck!

    avail: 2mg/ml & order: 30ml/hr

    a. mg/hr=2mg/250ml x 30ml/hr=60/250 = 0.24mg/hr

    b. mcg/hr=1000mcg/1mg x 2mg/250ml x 30ml/1hr = 60000/250 = 240mcg/hr

    c. mcg/min=1000mcg/1mg x 2mg/250ml x 30ml/1hr x 1hr/60min = 60000/15000 = 4mcg/min

    *****dimensional analysis, learn it and you can work out most any dosage!

    apply to next q:

    a. mcg/hr = 600mcg/hr

    b. mcg/min = 10mcg/min
