believe-in-laughter asked: I just saw your meme about the saline flushes. Here's a trick- loosen the cap a little while its still in the bag just until it pops. You will only lose a very small amount and the flush will still be effective. Another trick that my clinical professor taught us is pull back on the plunger while its in the bag. It will also pop and you won't lose any saline, just make sure you get the air out before flushing! Hope that helps!
