Are you familiar with the factor-label method of problem solving? If not, please become so. It is imperative to learn in order to be able to solve any type of calculation problem without memorizing each scenario. In my experience, the vast majority of calculation errors could be avoided by learning this simple method. Check in your Chemistry text or make an appointment with a tutor. It will be time well spent.

In your example, you are to infuse 3000ml of IVF over 24 hours with a drop factor of 10.

This is the factor-label method of solving the problem:

3000ml x 1 hour x 10 drops = 20.83 drops/minute

24 hours 60 minutes 1 ml

There is a book titled Math for Meds (Anna Curren) that give excellent (logical) step-by-step instructions on these types of problems and so many more. The used (older edition) text is just fine. It is an great resource with lots of practice problems.

Does your library have it? Or maybe a copy in the nursing dept. office?

Good luck!

ok.....here's how i remember how to do it:

take the amt of ml which is 3000 times the drop factor, which is 10 that gives you 30000....now divide that by the # of minutes you need to infuse it....so it says 24 hours...so 24 hrs times 60 min = 1440

so 30000 divided by 1440=20.83

your answer would be 21 gtts/min

Ok...here is the simplest way I can think of.

3000mL/24 hrs. = 125 mL/hr

125(mL/hr) x 10 (drop factor) / 60 minutes = 20.83

You would round to the nearest whole number, so your answer is 21 gtt/min.

im just an lvn and here's my simple solution

3000 ml (10gtt/ml)

________________ = 20.83 r/o to 21

24 hr ( 60 min)

where did we get the 60 min, its not even given in the problem. well its because 1 hour is = 60 min and you need to convert 24 hours to minutes which will give you 1440 minutes, because if you will not convert it into minutes and you will just divide it with 24 hours you will get this answer (1,250) which is wrong.
