    Figure out how many units per ml and go from there.

    One plus one equals two...so two minus one equals one

    600,000 mg is half of 1,200,000 - so you would do 1/2 of 2ml, which would be 1ml.

    Very nice of you to do this but it kind of defeats the purpose of teaching. Generally speaking we try to offer clues to help the student figure it out for themselves so they can do it again when faced with similar problems in the future.

    Thank you but say I had 900,000mg/2ml. Do I do 900,000/1,200,000, which equals 0.75 and multiply that by 2ml which equals 1.5 mls

    I have no idea what you've done here. What dose do you want? 600,000 units? If so where did you come up with the 1,200,000? Show us how you set up your ratio.

    Ok the question is if you have Bicillin 1,200,000/2ml and the doctor orders 600,000, how many mls do you give. I did 600,000/1,200,000 and got 0.5 and then did 0.5 mutiplied by 2ml and got 1ml. So is this right and is so I do the same process if the doctor orders 900,000 right?

    And generally, we tell nursing students who post in the School Nurse forum by accident, that they should find the right forum. I was just trying to answer her question.

    To the OP: This is the School Nurse forum. You might find the help you are looking for in the forum for nursing students.

    Okay now I see where you got your figures. Although it isn't the way I do it you have the answers correct.

    :woot: 600,000 is half of 1,200,000 so the dose is half of the container...no algebraic geometrical calculus formula needed. I can prove it easily on my abacus!

    Couple things.

    First- The formula is (DOSE/HAVE) x VOLUME. In this case DOSE (600,000mg) divided by HAVE (1,200,000) and then multiply that result by VOLUME (2mL)

    600,000/1,200,000= 0.5

    0.5 x 2= 1

    Answer is 1mL

    Second- is this homework? We are school nurses, not nursing school.

    But I love to help with math :)
