Hello all, Can you help me with this problem? I think I am reading too much into it, and it might be easier than I am thinking it is...

500ml of a solution was ordered at 35ml/hr. You have a 60 gtts/ml administration set available. What would you administer?

VTBI

____

Time(mins) X gtt factor= ?

So..

500ml

_____ X 60 =

?????

I know it says 35ml/hr, but that is throwing me off! Someone help, and hopefully tell me I am on the right track!:clown:

Thanks in advance.

i hate problems like that, lol. sometimes they give you a drip factor just to throw you off. either way, i got 35.

are you running it on a pump? if yes, then 35 ml/hr. pumps are always ml/hr.

if you want drip factor, then you have to read into it further...

500ml / 857 mins (500/35 = 14 hrs x 60 = 857 mins) x 60 = 35 gtt/min

i hope this helps. :)

you will administer 35 ml/hour. that is what the doctor ordered. using a 60gtt/ml set (that is microdrip tubing) your drip rate will be

35 ml/hour
(infusion rate)
x 60 gtts/ml
(drop factor of iv tubing)
x 1 hour/60 minutes
(conversion factor)
=
35 gtts/minute
(drip rate)

something you should notice with microdrip tubing. . .when you know the ml/hour the drip rate will always be the same as the ml/hour. this is always true when you are using microdrip tubing that has a drop factor of 60 gtts/ml--always.

the 35 ml/hour = 35 gtts/minute -
with microdrip tubing

I also get 35gtt/min. We are required to do dimensional analysis, so here it is:

gtt/min = 60gtt/1ml x 35ml/1hr x 1hr/60min = 2100/60 =35gtt/min

It is often a pain but we have to do all calculations in this form and make 90 or above (1-2 problems) on all DA tests or out of program.
