I'm doing some practice problems, and this is from nursesaregreat.com: A procainamide drip is ordered (2 gm in 250 cc of D5W) to infuse at 4mg/kg/min. The patient weighs 165 lbs. Calculate the drip rate in cc/hr for which... Read More

    Wow. Thanks for all the help. I'm going to assume there's something wrong with this problem. I'm trying to re-learn all these calculations that I haven't done in years and years, and it doesn't take much to confuse me. I have been using dosagehelp.com to practice, and I'll check out the other one that Esmel reccommended. I'll have to take a medications test at the hospital, and I'm trying to get all this straight in my head before I go in there!

    Thanks!
    There's nothing wrong with the problem.

    In this case, the patient's weight is irrelevant - it doesn't impact the dose, so it's simply left out.

    dose ordered = 2 g in 250 cc (cc = mL)
    infusion rate = 4mg/min

    4mg/min x 250mL/2g x 1g/1000mg x 60min/hr = 30 mL/hr

    The thread is over a year old....and I beg to differ.......the weight IS relevant.....

    A procainamide drip is ordered (2 gm in 250 cc of D5W) to infuse at 4mg/kg/min. The patient weighs 165 lbs. Calculate the drip rate in cc/hr for which the infusion pump will be set at.

    This math question is all about the weight.
