1. HELP.....I've tried everything I can think of and still can't get the right answer

    Calculate the total mg of hydrocodone the patient will receive.
    Ordered: Hydrocodone/Acetaminophen Elixir 2 tsp. PO now
    On hand: Hydrocodone 7.5mg/Acetaminophen 500mg/15mL Elixir

    First...convert the tsp to milliliters. 1 tsp = 5 ml

    Start with the order...always...

    So for every 15 contains 7.5 mg of Hydrocodone.

    So you take 15 ml's and divide by 7.5 mg...that gives you the mg of Hydrocodone per ml...DO NOT ROUND THAT ANSWER. know that 2 tsp was ordered...that is 10 mls...take the 10 mls and multiply it by the above answer.

    That gives you your Hydrocodone for the order.

    PS: That is a bad question to start with...a physician cannot give you an order for an Elixir that contains two medications, with an order for ONE of them without any instructions for the don't worry, you'll probably never run into that on NCLEX or in real life, for that matter.

    I have 7.5 mg in 15cc, want ?mg in 10cc
    7.5mg hydrocodone:15cc :: x:10cc
    5mg in 10cc

    Remember, 5cc is 1 tsp, so 2 tsp is the same as 10cc
    In real life that's not a drug I give in liquid form, so I'd also be checking the bottle, make sure the label on what you have says 7.5 mg/15cc.

    This is a basic math problem in everyday nursing. How many pills to give, how much of an injection to give--Lopressor, Vasotec, heparin bolus IV all may need a little drug calc performed.

    Just a thought. There is no dosage in the order and hydrocodone comes in different concentrations. (ie - 5/325, 5/500, 7.5/500 - etc.). In the real world, I'd call the prescriber for clarification. Pharmacy would kick that right back to us as well.
