1Aug 24, '13 by MunoRNI'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".Esme12 likes this. 
1Aug 24, '13 by KelRN215, BSN, RNQuote 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.
