3. I'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".

What 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.
5. Yeah, 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.
6.  Volume (mL) = Y (Flow Rate in mL/hr) Time (hr)

OR

 Volume (mL) x Drop Factor (gtts/mL) = Y (Flow Rate in gtts/min) Time (min)
