interesting question as there are many possible answers because they have left out one of the elements to determine drip rate and that is the drip factor of the tubing you will be using. just reading what you wrote i would assume that they are looking for all possible answers. a chemo drug could be mixed in a 100cc piggyback bag. it could also be a 1000cc bag with a chemo drug mixed in it. i don't know of any specific chemo drug that is given specifically with a micro drip (pedi drip), but i'm not that up to date on administering chemo so i could be wrong.
so, 100cc of fluid administered over 2 hours gives you a figure of 50cc/hr
10gtt/min tubing--> 8.3 gtts/min (or rounded to 8gtts/min)
15gtt/min tubing--> 12.5gtts/min (or rounded up to 13gtts/min)
20gtt/min tubing--> 16.6gtt/min (or rounded up to 17gtts/min)
60gtt/min tubing--> 50gtt/min
on an iv pump-->merely set the pump for 50cc/hr.
if you are talking about choice of tubing:
first, go for an iv pump
secondly, for a piggyback with whatever piggyback tubing you have
third, a mini-infusion pump
fourth, if non of the above are available i would use a burette tubing with a mini drip (60gtts/min)
those four methods are the best way to control the amount of fluid you are giving.
here are some web sites to help you with iv drip calculations?
