What is this Dosage problem asking?

Published

Ok here is the question:

The order reads Asa gr X po now. You have Asa 325 mg per tablet. How many tablets should you give?

Well I took the question to mean that the order of the Asa (in grains) is to be given by mouth but what does X mean? I looked to a few medical terminology websites but I still don't know what X means and what the question is asking.

I have a dose question with an answer but I still can't figure out how the answer is what it is, so if anyone can explain it I would appreciate that:

A nurse is to give the liquid medicine 3 times a day. The morning dose is 3/4 ounce, the noon dose is 1/2 ounce and the evening dose is 3/4 ounce. The nurse has 1 ounce of medicine at noon. How much more is needed?

The answer is 1 .....I do not know why

I don't get this question, maybe I am over thinking it, has the nurse already given the noon dose when she has 1 ounce left or does she have an ounce at noon prior to the noon dose? Why is the answer 1?

I don't get this question, maybe I am over thinking it, has the nurse already given the noon dose when she has 1 ounce left or does she have an ounce at noon prior to the noon dose? Why is the answer 1?

1) The nurse has: 1 oz left at noon.

2) At noon, she gives: 1/2 oz

3) She still needs to give: 3/4 oz in the evening

So...

The nurse needs to make sure she has enough to cover the evening dose, right?

1 oz total left - 1/2 oz given = 1/2 oz left

That's not enough. She will need more to complete the 3/4 oz dose

3/4 - 1/2 = 1/4...

So if she has only 1/2 oz left after giving her 1/2 oz noon dose... she needs 1/4 more ounces.

But what if she didn't give the noon dose yet? Let's try it that way:

The nurse gave her noon dose.

She has, after doing so, 1 oz left.

She needs to give 3/4 oz for evening.

She would then have more than enough, if she has 1 oz left, after giving the noon dose.

I don't get 1 oz either way and I think it's a poorly worded question.

Maybe I'm missing something too.

I'm curious to see what others come up with.

The only thing I can think of is incorrect wording. Maybe 1oz is what they have in the am. Then they would need 1oz to finish the noon and evening dose. Maybe it means 1oz to last til noon if so it works out.

3/4 + 1/2 + 3/4 = 2 oz = 1 oz in the am and 1 oz at noon to finish the last doses.

1 oz to be given 3/4 at am and 1/4 at noon.

1 oz to be given 1/4 at noon and 3/4 at evening.

That's the only way it works out for me.

hygiene queen and i agree.

let's look at the question this way. you are working on the floor. you have just given your morning dose of the liquid. you note that you have only 1 oz of liquid med left in the bottle. by doing some simple subtraction you realize you must order more med if you are to give the evening dose.

[you know you have 1 oz on hand and you must administer the lunch dose of 1/2 ounces and evening dose of 3/4 oz = 1-1/4 total ounces you will give. you have 1 oz on hand = 1/4 ounce missing. you will have to requisition more ounces if you want to give the evening dose. you are covered for the lunch dose.]

if you note the 1 oz left in the bottle after giving the lunch dose, you have eough to give the evening dose.

i have seen many poorly worded questions similar to this one. if this was taken out of a book, many books post incorrect answers.

as to the correct answer---contact the professor about the discrepancy and ask for an explanation.

1) the nurse has: 1 oz left at noon.

2) at noon, she gives: 1/2 oz

3) she still needs to give: 3/4 oz in the evening

so...

the nurse needs to make sure she has enough to cover the evening dose, right?

1 oz total left - 1/2 oz given = 1/2 oz left

that's not enough. she will need more to complete the 3/4 oz dose

3/4 - 1/2 = 1/4...

so if she has only 1/2 oz left after giving her 1/2 oz noon dose... she needs 1/4 more ounces.

but what if she didn't give the noon dose yet? let's try it that way:

the nurse gave her noon dose.

she has, after doing so, 1 oz left.

she needs to give 3/4 oz for evening.

she would then have more than enough, if she has 1 oz left, after giving the noon dose.

i don't get 1 oz either way and i think it's a poorly worded question.

maybe i'm missing something too.

I never came back to this question and it's funny because on my Kaplan exam I had a question very similar, I asked my Pharm professor and she said the doses may be 1 ounce vials, and the nurse discards whatever is left, in some cases once a med is open whatever is not used is discarded.

normally, if it is a one dose vial, usually it is stated so on the vial or in the question. am i right or wrong? in this case it was "liquid medicine"--it does not say whether the route is po, iv, im or? instead, we are left guessing. don't you love questions like this.

even my pharm professor who was a nurse for years, kinda took the question like "well i think it's this", meaning as so many have said here, it is a poorly worded question. i gave it to you folks the way it was and i could not make sense of it, but i also got this kinda question wrong on my kaplan and math was my highest section 89
