    1 gr = 60 mg

    The ss with the line over it means "half" - that help?

    Hey,

    I'm not sure what the "i" stands for but the ss with a line over the top means one-half..

    "gr" stands for grain,

    One grain= 60mg

    1/2gr= 30mg

    This is the only thing I can think of for that problem..

    The i is like roman numerals. i is 1, ii is 2, iv is 4, etc Always with the squiggle over them and yes, the ss is 1/2. We just saw that on our ERI tests & everyone was thrown for a loop. I have only seen it in use in the MAR for PRN meds. When a patient could have 1 or 2 tabs, the nurse used this way to indicate how many she gave.

    gr (grain) i (one) ss (half) is 1/2 half grain

    the little i is the roman numeral for 1. You might see it as i or I. With grains it tends to be the smaller case i. therefore ii would be two and iii would be three.

    so in the case of the gr i ss it means 1/2 grain which converts to 30 mg (since 60 mg is 1 grain)

    Hope you read this before you left for your exam :spin:

    Are you sure? The way my teacher explained it, the ss would mean an additional 1/2. So it would be 1 1/2 grains. I'm not saying that you are wrong. I'm just confused now.

    Oh wow! I was looking at the example in my book that read gr ss i which is 1/2 grain! Yes Dixie, you are absolutley correct. gr i ss is 1 1/2 grains which would be 90 mg. (1 full grain = 60 and 1/2 gr =30 so he answer would be 60 and 30 making it 90mg.

    so, so sorry. It was really early when I read the post.

    Oh and wanted to add that roman numerals are in upper cases and apothercary notation i in lower case.

    Arabic number 1, 2, 3
    Roman Numeral I, II, III
    Apothecary Notation i, ii, iii

    CT Pixie,
    I guess we both learned something. I hadn't realized that ss i would mean 1/2 or that ii would be apothecary notation. I was just told it corresponded to the Roman numerals. I wondered why they didn't just use capital letters then. Now I understand.
    Thanks. I am about to graduate from PN school in a couple weeks. How much you want to bet, I won't see this on the NCLEX-PN? If I do, I have you to thank and hopefully this helps the original poster.
    Now if this would only help with my Acute Med/surg GI & GU test this morning.

    just like IV is four..not 6..you read it 5-1=4, the ss i would be 1 - 1/2=1/2. Whenever there is a smaller number before a larger one (IV, IX, etc or ssii) you subtract the smaller from the larger to get the number.

    I have 9mths and 6 days (14 hrs and 49 minutes)before I graduate PN school...but who's counting

    1 grain=60mg and ss means half so iss will mean one and a half thus giving u 90mg of the dose
