Are you talking about microdrips? If so, microdrips are 60 gtt/cc. Try using this formula cc/time x drip factor (drops (gtt)/cc or ml). When a question asks you for the drip rate, they usually want it in drops per minute, so you may have to convert the time (hrs) into minutes. I hope that this isn't too confusing.:bugeyes:

oops sorry... what i meant was gtts not qtts :bowingpur

for now i know the formula of my letter B follow up question.. what really bugs me is the first question

the problem is asking for the RATE of the IV fluid and to get that i was thinking of volume x qtt factor

duration x 60min/hr

my queston is...where's the volume in the problem?? 80cc/hr or 500cc? and what's the duration? my classmates used the 80cc/hr and some used the 500cc.....im just waiting for the results of our assignment now... someone please enlighten me :banghead:

thanks CISCOPATRICK06 for your answer....

d5imb 500cc at 80cc/hr. how many micro gtts/min will you run the iv? my question is...where's the volume in the problem?? 80cc/hr or 500cc?

the volume the bag of iv fluid is 500 cc. there are 60 microdrops per cc. that is also the same as 60 microdrops per milliliter (ml). so,

80cc/hour
(ordered rate of infusion)
x 60 microdrop/cc
(drip rate of microdrip iv tubing)
x 1 hour/60 minutes
(conversion factor--hours to minutes) =
80 microdrops/minute

if you received a full bottle at 7am, how many cc will you endorse at

12noon?

from 7am to 12 noon 5 hours will have passed with the iv infusing at 80cc each hour for a total of 400cc's:

80cc
(7am - 8am)
+ 80cc
(8am - 9am)
+ 80cc
(9am - 10am)
+ 80cc
(10am - 11am)
+ 80cc
(11am - 12 noon)
=
400cc's

then,
500cc
(amount of iv fluid you started with)
- 400cc
(amount of iv fluid infused)
=
100cc
(amount of iv fluid left in iv bag endorsed to next nurse in charge of patient's care)
