Just wondering is this correct? (# of ml's flushed and the aspiration?) When you are pre-flushing a saline line with NS before giving an IV push med, do you flush with 1 ml then aspirate for blood, than flush 2ml (with first 10ml NS prefilled syringe). Next admin the push med at prescribed time, than connect 2nd prefilled syringe and flush with 3ml.
Is there a reason we can't just use the one prefille syringe, because there is enough in there for both flushes? Would that be considered unsterile because of the aspiration of blood that you do in the first flush??
Also, with central lines you always do the full 10ml flush of NS, because the tubing is longer right??..Before flushing would you instill 2-3ml than aspirate for blood, than instill the full amount in the syringe?
Thank you in advance for your help!! (sorry if my questions are confusing)
