Basic pharmacology question

  1. I'm doing a pre-quiz for pharmacology & for some reason I can't seem to find information to answer my question.

    the problem is- administer Tylenol gr v po. The label on the available message reads"Acetaminophen 325 mg/tablet". How many tablets should be given?

    I know the actual answer is about 92%- but how would the answer be phrased? I can see splitting a tablet in halves and quarters but 92%? is that the correct answer?

    thanks for any of your help!

    Seems like you're missing something from the question and, no, you cannot give 92% of a tablet.

    The information they're asking for is "dosage, route and time medication ordered. Tablets come scored."
    Would you just give one tablet in this case? I'm a brand new student, but I know that gr V=5 grains, which translates to 300mg. if I only need 300mg (or 92%) what do I do with the remaining 25mg?

    You can't possibly give 300 mg of a 325 mg tablet. I would call the MD and get the order changed in this case or give liquid formulation.

    All right, I'll ask my professor about that one just to clarify. thanks for your help!

    My conversions say that 1 gr is equal to 60-65 mg. :-)
