Dosage Calculation (Heparin)

  1. 0
    Hello nurses and student nurses..
    I need some help figuring out the answer to a heparin problem. I'm coming up with an answer but I'm not quite sure if I have it correct. Please guide me...
    4. ORDER: Give a heparin drip of 25, 000 units in 500 cc D5W at 9 cc/hr

    Heparin: Prevents recurrence of thrombosis; use with tPa. Adjust dose to keep
    APTT at 1.5-2.0 times control. ASA often given with heparin. Protamine reverses
    heparin. Watch for bleeding.

    Available is 10,000 units/1 cc

    QUESTION: How many cc of heparin would be added to the IV?

    Would this formula work?
    Desired amount = cc
    Conc in sum

    QUESTION: What is the concentration of heparin per cc in the IV bag after
    itís mixed?

    QUESTION: How many units of heparin per hour is the patient receiving?
    QUESTION: If the MD ordered the drip increased by 200 units/hr, what
    would the IV rate be (cc/hr)?

    Omg what a question , i'll give it a shot
    needed 25,000 units of Heparin on hand 10,000 unit /1cc

    so 10,000units : 1 cc :: 25,000units : x
    10,000:1::25,000:x
    1 x 25,000 = 25,000
    X x 10,000 = 10,000x
    10,000x / 10,000 = x
    25,000 / 10,000 = 2.5 so x = 2.5cc

    2.5 cc of hep will be added to iv
    25,000/2.5cc cocentrate
    9 cc/hr

    question: how many cc of heparin would be added to the iv?
    25,000 units/ 10,000 units/ml = 2.5ml

    question: what is the concentration of heparin per cc in the iv bag after
    it’s mixed?

    25,000units/500ml = 50units/ml

    question: how many units of heparin per hour is the patient receiving?
    answer is in the order; 9ml/hr.

    question: if the md ordered the drip increased by 200 units/hr, what
    would the iv rate be (cc/hr)?
    here is how you solve this one. your original order is for 9ml/hr, right? that means you are running 450 units of heparin per hour (50 units/ml x 9ml). now the md ordered an additional 200 units per hour for a total of 650 units/hr. so: 650units/50 units per ml = 13ml/hr.
