Calculating IV drug infusion using Volume ctrl set (pediatric)

by Sherri
(Raleigh, NC)

I can't seem to figure out how much IV fluid (mL) to add to the chamber.


Ordered: D5 0.33% NaCl IV at 66 mL/hr with Fortaz 720 mg IV q8h to be infused over 40 min by volume control set

On hand: Fortaz 1 g/10 mL

The book says the answer is 36.8 but closest I've gotten is 36.6 or 36.7. I don't know if thats the closest you can get or if there is a way to get 36.8. Can you walk me through this and give me formula to figure this out?HELP!!!

Also:

Ordered: D5W at 30 mL/hr for continuous infusion with medication x 60 mg q6h to be infused over 20 min by volume control set

On hand: Medication x 60 mg/2 mL

The book says the answer is 8 but I'm getting anything but 8.How did they come with 8? And in the first one, how can I come up with 36.8?
