I am nursing student, in my second semester, and we arre studin GI right now....our book says to stip the feeding, flush the tube with 30cc of sterile solution, give the med, flush the tube again, start the feeding back after 30 min. These is to insure the patency of the tube and allow the medication time to absorb.....Is this right? I don't know...but thats how I understand it.
