100% dosage calculations?

MiaKeaRN · Jan 16, 2008

We just took our test on Monday night and had to get a 92% to pass, with one chance to retake. I would guess that 25% did not pass and will have to do the re-take, but there was some confusion on when we had to take it. This was our first class back for the semester, and a lot of people didn't understand that we would be tested at this first class. I felt so awful, but hopefully with a week to practice they will pull through with flying colors!! I believe that 3rd & 4th semesters we have to achieve 100%.

The stress of these tests is just awful. I was so sick when I came home that I could barely keep my eyes open from the pounding headache I had.

Good luck to everyone here who has a pending drug calc test. Practice, practice, and more practice will make it easy on you.

We have to get at least an 80% and get to dry 3x

We had our test the other day which we were required 100 %, and we all passed :)

It wasn't to bad, just study and practice and you will get it.

wow 100%? my school required that we pass our dosage exam with a 90% and above..we had two tries. the first exam consisted of 50 questions to be done in 2 hours..and you can only get 5 mistakes to pass with a 90%. and the second exam had 40 questions..and you can only have 4 mistakes. this had to be done in 1 hour and 30 mins.

my school requires us to score 100% each semester, we had a test the first day of classes and had to score 100% to be able to pass meds. Don't worry your not the only one!

In most areas 80% is okay, but if you can't do drug calculations 100% correctly, you won't be safe passing meds. Too many threads in here about the agonies people put themselves through after med errors.

Having several chances to prove yourself works for me though! I tutored several classmates in doing drug calcs because I'd take a LOT of math in high school and pre-reqs. They all passed first time! I failed one question from not reading carefully enough and being over confident. Got it second go round with lesson learned: slow down and do it right the first time :icon_roll:icon_roll

Oh Lordy. Now remember I did that in 1979...(ahem:sasq: me in the stone age, giving pre-op sedation).

Keep your units in the right place: gtts/cc x cc/h x h/min=gtts/min

which makes sure you are multiplying (or dividing) the right numbers.

#mg/kg (drug str) x kg (pt. wt.) = mg (desired dose)

cc/h x #cc desired = hours (time) needed

mg/cc (drug) = dose in mgs/unk. ccs, cross multiply and solve for unk. as in:

known mg x unk cc = cc x dose, then divide cc x dose by known mg to get to the amount needed to give

when the units cancel out correctly you have it set up right.

Hello! Mam, pls help me with my dosage computation. i don't know if this is correct or wrong... Here's the problem, doctors order is 1.5 G of cefuroxime,stock dose is 750mg. So my solution is D/S x Q,

convertion? 1.5g x 1000mg=1500mg , then 1500/750 x 10 ml =20ml

the diluent is 10ml is that correct for adult? i'll gonna give the whole 20ml in 1 shot? is that overdose for adult or what? Sorry for me... Thank you!

I don't know where the 10ml comes in but, 1500mg/ 750mg is 2ml. Is the 750 diluted in 10mls? You need to figure out how many mg per ml diluted and then plug those numbers into the problem I believe. Explain this better if you can so I can see the whole picture.
