Why don't you post what you have done? This will allow us to better help you find the answer.

I will show how to solve but you need to find the answer.

The first question you need to ignore what isn't necessary and that is the 750ml of 0.9% saline, it is not needed.

Next you have 11gtt/min, there are 60 minutes in an hour so:

11*60=x

Then there is 10gtt/ml, so:

x(answer from above) diveded by 10=how many milliliters per hour

The second question: First find out how many units in one milliliter

50,000 divided by 500=x

then find out what 900units is in milliliters

900 divided by x (from above)=

This gives you your answer

I can't thank you enough ! It is just what I needed.. The Formula. My professor does not teach us at all and we have to figure out everything ourselves which is tough. This test will be my last before the final. Got 96 on the first and 100 on the second. All self taught ! Now I know how to do this type of calculation... Thanks again I really appreciate it !

also, for any other students who are reading this and shaking their heads in rueful agreement at the unfairness of it all because "my professor doesn't teach us at all and we have to figure out everything ourselves which is tough"... stop right there.

nursing is a profession. you will be a professional. this means that you will have responsibility for life-long learning. part of what you're learning in nursing school is something that might not be explicitly stated in the course catalog, but it is there nevertheless: you are also there to learn how to seek out what you need to know and to teach yourself.

now, don't whine that it's the teacher's job to teach you, they get paid for it, you're in debt for tuition, you deserve to be taught. all of this is true, but it doesn't discount what i said above: you are, and will always be, responsible for your own learning.

so if you find that your professor isn't teaching you med math (which, btw, you ought to have learned in high school sophomore algebra anyway), get yourself over to the learning lab or the remedial math department or the math club and find someone to refresh your memory. also, you will learn someday that there's nothing like having to teach something to make you learn it. get together with a few other students and teach each other how to do med math situations. do it on your own time...because you have to. adults recognize these situations earlier rather than later.

Order: 750ml 0.9% NS IV at 11 gtt/min. Drop factor is 10 gtt/ml. How many mililitters per hour will the patient recieve.

This was a good review. I've had these concepts but I don't see them applied in this fashion very often. We are given medication worksheets but I haven't seen one quite this one in awhile. The other question wasn't too bad. :) The concepts are there. Believe me! I hated med math initially. One day, it clicked after I went through a TON of problems on dosagehelp.com. I strongly recommend that site!!!

i'm a nursing student, and i can't express how correct you are. i don't think you could be more right if you tried. just because we are in school doesn't mean that it is the instructor's responsibility to teach us every last detail. there should be some self-directed learning.

Thanks so much for the site :). I am going to check it out tomorrow and do a bunch of problems. I was so stuck on those two questions. All I needed was the formula that Fortheloveof was kind enough to walk me through and I was good to go.
