# Math question stumping me

Albumisol is to be administered at a rate of 3cc/min. You are giving 50cc of albumisol via tubing with a drop factor of 20gtt/cc. How many drops per minute should you regulate the IV to infuse?

gtt/min= 20/1 x 3/1 = 60 gtt/min, it makes sense to me because if 20 gtt = 1 cc and the iv is to infuse at 3cc/min then 60gtt/min would equal 3cc/min

does that seem right

this is just practice but i haven't been stumped by a math problem is a while and it is bothering me that i cant figure out this simple math question. I came up with 3 different answers but I'm sticking with 60, unless someone can point me in the right direction on how to solve the problem.

I agree-but I reserve the right to take it back after I have some sleep and some food.

I'm just coming off 4 12 hour night shifts.

3cc x 60min= 180cc/hr

180cc/hr x 20gtt/cc

60min

60gtt/min

yes, andy, you are correct. you want to end up with a ratio, or fraction, with labels of gtts/minute. the set up for this by dimensional analysis would be:

3 cc/1 minute
(rate of infusion desired)
x
20 gtts/1 cc
(drip factor)
=
60 gtts/1 minute

this iv infusion is going to be done in about 17 minutes.

Albumisol is to be administered at a rate of 3cc/min. ...via tubing with a drop factor of 20gtt/cc. How many drops per minute should you regulate the IV to infuse?

.

That's all the info you need to solve the problem

3ml per minute=180ml per hour

With drip rate of 20, just divide your hourly rate by 3.

60ml per hour.

(with a drip rate of 15, you'd divide by 4, BTW)
