The dreaded dosage test

  1. Hey I have an idea---actaully I was inspired by the practice quiz threads.

    For those of us that are about to take our dosage test, how about we post our practice questions on this thread for extra practice.

    How does this sound?

    Just an idea. Let me know if anyone is interested, and I'll post some of the ones that we were given for practice.

    1. You shouldn't be giving demerol, it sucks

    2. pretty weak dose for q 12, find that patient a new md.

    3. Nobody gives pcn IM anymore, again, new doc time

    4. No route, not a valid order

    5 1 gram tid is a much better dosage.

    Just curious -- do you have to learn all of the conversions or are you allowed to use a cheat sheet?

    We have to learn all of the equivalents, but when I took an RN course before we didn't have to based on the fact that they are always available to a nurse anyway.

    Disclaimer: I am NOT good at this! LOL, our math was briefly gone over for the first time on Tues. and my conversions may be wrong, but this is exactly what I was going to work on soon anyhow...

    1. 0.05 minims
    2. 1 ml
    3. 1.6 ml
    4. 275 mg
    5. 500 cc

    Okay, here is my calcs then:

    1) first conversion s/b from ml to minims (answer will be in minims). 1m/15ml x 1ml/75mg x 60mg dose = 0.05 minim

    2) first conversion s/b from ml to tsp (answer will be in ml) 4ml/1tsp x 1tsp/0.5 mg x 1mg/1000mcg x 125 mg dose = 1 ml

    3) 4ml/5 million U x 2 million U dose = 1.6 ml

    4) 15mg/kg x 1kg/2.2 lbs x 121 lbs/patient in 3 doses = 275 mg / dose

    5) 1cc/5000mg x 1000mg/1g x 2.5g dose = 0.5 cc
