The other day, I was having a conversation with a friend of mine who graduated last year about school. Well, during the course of the conversation, I mentioned that I forgot to aspirate when flushing with NS before giving an IV push, and the instructor didn't call me on it, although I did aspirate with all the other flushes. My friend told me that you don't aspirate when flushing with pushes. Now, I know that this is probably a preference thing, but this year I was taught to aspirate with a flush to check the patency of the line. I have also seen other nurses do this, so I know that this practice is out there in existance. I am just curious as to how many other students or nurses have heard of this practice.
