# does your school require a dosage caluculations test that has to be above 90%? - page 3

I just found out today, that my school has a test every semester in dosage calculations. In order to stay in the program, a student needs to get 90% correct. There is only one try. Don't you think... Read More

1. Yes, my school does. Every semester in fact. You have 3 tries, and you must get a 95% or above, or you are dropped from the program.
2. No calculators at my school either.
3. we have to get 100% on our tests but we get 3 tries to take. personally the math isn't exactly rocket science. one girl in out class missed the following question, which she thought was so hard and i thought "God, if I am ever sick please don't let her be the one to take care of me"
" you need to give PT X his medication. the order reads give pt 250 mg of tylenol. in the drawer you have the following 3 capsules marked 100 mg each and 4 capsules marked 25 mg each. how many pills would give total and what strengths?"

okay how hard is that?? umm 2 caps marked 100 mg and 2 marked 25 mg for a total of 4. she also missed the sliding scale insulin question example below

your patient has a blood sugar of 300. he is getting 15 units of fast acting insulin. using the scale below how many units of regular will he get and how much total insulin will he recieve?

150-225=5 units
226-265=7 units
266-290= 10 units
291-315= 12 units
316-330 =15 units

so his BS is 300 so he will 12 units of regular. he is getting 15 units of fast acting so 15+12= 27 total units.

again stop me if this is hard. this something that is fundemental to nursing. we are talking adding, subtracting, multipling and dividing. skills learned in elementary school. we are not asking people to do calculus here anything
4. We had one first semester and it had to be 100%. In Med-Surg I & II we had dosage calc questions in the exams, but we just need an overall grade on the exam, no special requirements for the dosage calcs.
5. Kris,
Are they really that straight forward? That is a little reassuring.

Well I am glad at some schools they are said to be that straight forward, but frankly at mine they were not. Yea it's not rocket science as was stated, but ours were not THAT simple.:stone
7. Ours requires a 90% but you get 3 tries. It is done every semester, the first week usually.
8. Come to think of it, I think some of the ones during our OB rotation actually WERE rocket science. I'd get to the end of the paragraph (question) and think...What was the question? :chuckle

But, hey, it's good for me. I remember first semester when an instuctor was going over information for med math testing, and someone complained about a 90% to pass. She made the point that when dealing with someones life, she would prefer it would be a 100%...as others said, would anyone want someone taking care of them that could not get a 100% on a dosage calculations test?

Med Error --> DEAD PATIENT!!! :imbar
10. We have a calculations exam each semester before we can begin clinical. Must make a 95% or better within 3 tries. Of course, they increase in difficulty each semester, but so far I haven't found it to be that difficult - once you memorize the conversion factors and formulas!

Exactly, which is why i don't see this as being too hard on people.

If my nurse only got 20% of my meds correct in a day, I'd be p***ed (if not dead, considering one of mine is for cardiac reasons). I relate dose calc tests to real life.

Exactly!! I don't think it's possible to take 'nursing math' too seriously.....the first time I took one of those math quizzes, I got a 95%, but on the one problem I missed, I 'killed' a patient with a tenfold overdose of KCl. :stone Lesson learned, and cheaply, thank God!
13. The CC I'm at requires ALL students applying for health related degrees to take "MATH for HEALTH CAREERS"---you cannot be accepted without it. the course description follows:
" the student will convert units of measure within and among the metric, apothecary, and avoirdupois systems of measurement; solve pharmacology problems; apply algebraic concepts to signed numbers, formulas, and graphs; and use statistical software to analyze data with descriptive statistics and linear regression. "

WOW! you had better be prepared for dosage calculations after this class!
