There are 110 tablets available. Each with 8mg of the drug.

24mg is a multiple of 8mg. How many tablets is that?

Thank you. I have problems with certain wording questions. thanks.
4. I believe 86 tablets will be left. Am I correct?

Not quite. How did you get that?
6. The current Drug S 8mg tablets balance in the wards CD register is 110.

110 is in the CD register

24mg will be taken away so 86 will be the new stock balance?

Refer to the part where I said that there are 110 tablets available, not 110 milligrams.

What you're doing incorrectly is taking away milligrams from number of tablets, which makes as much sense as taking away oranges from apples - they are not the same thing.

A tablet has more than 1mg of the drug.
9. 110 -3= your over thinking. you are dealing in two quantities tablets and mgs you are required to give 24mgs the tablets are 8mgs so 24/8 =3. your drug stock is 110 less 3. if you had given 24 tablets you would have given 192mgs.you would probably have killed your patient. if it comes out a daft number youve done it wrong.

Thank you that is why I'm practicing
11. trust me im not great with numbers. just remember what your target mg dose is if you answer does not agree then its wrong. now drip rates scare me.
12. I think I got it now from everyone's post. 3 tablets will be taken so the remaining stock balance will be 107

Thanks.
15. There is an easy way of doing it aswell

You can use ratios (the sound of doom.but trust me they aren't as hard to use as the sound.
OK there 8mg has a balance of 110, so you can write it as a ratio of 8:110
Another drug is 24mg. OK. so how many times do you have to multiply 8 by to get 24?
Using the answer to that question multiply 110 with it as well to find the new stock balance.
You can use ratios for any questions like this and you will get the right answer using this method!
Make sure to thumbs up if it helped!

That's not right. What you are saying is that for every 110 tablets there is, there is 8mg. In fact, for every tablet there is, there is 8mg. The ratio is not 8 : 110, but 8 : 1.

Then multiply 1 by 110, and consequently multiply 8 by 110 to have 880 : 110, and then multiply 8 by 24/8 = 3, and multiply 1 by that to get 24 : 3. Then subtract 24 from 880. Divide that number by 8. Then multiply 1 by that result, and that is your answer (because 8 : 1).

Or instead of subtracting the number of milligrams used from the total amount, you could subtract the number of pills used from the total number of pills and get the answer immediately.

This is in fact a conversion problem. Two quantities in different units (mg, and pills) and you must calculate the difference, but to do so you must convert
17. wow that looks nicely open to produce an error. i think i will stick with my way its not messed up yet in 30 years. lets take paracetamol but only if you need to. a patient is needing 4 grams per day. ward stock is 100. my way tabs are 500mg so 4 grams = 8 tabs leaving 92. please show us your way im puzzled. remember it needs to be simple a tired nurse can make mistakes.
