Can someone help clarify this pediatric dosage problem

1. Order: Gentamicin 8 mg / kg /day q6h for a child weighing 72 lb.
a. Give ____65 mg/ dose ______ mg per dose.
b. Gentamicin is provided as 80 mg / 2 mL.
c. How many mL would you draw up/ ______1.62 or 1.6 mL _______
d. The Gentamicin is to be added to 15 mL of IV fluid and infused over 60 minutes.
e. How fast would you set the IVAC? _______ mL per hour________________
I can get everything else but I am having trouble understanding E. 

Aug 24, '13I've never heard of an "IVAC" either, but after looking it up apparently it's a brand name of an IV pump, which is a really inappropriate way to ask this type of question.
Anyway, the E basically asks what rate, in mls per hour, that you would set the IV pump to run at, although I don't know why there's another blank after "hour". 
Aug 24, '13Quote from Matt1986What is the total volume after you dilute the Gent with 15 mL? You want to infuse that total volume over 1 hour so that's your answer.1. Order: Gentamicin 8 mg / kg /day q6h for a child weighing 72 lb.

Aug 26, '13Yeah, really, let's not overthink this. When a dose (of anything) (in X amount of fluid) has to be given over an hour, the amount of fluid it's in is your answer Xcc/hour.
