I started nursing clinicals and I have encountered poop, pee, vomit, mucus, etc. I was a CNA for 2 years and loved it, so this doesn't bother me, but one of my nursing friends who graduated claims that she's seen so much "dirty" stuff that she quit working at the hospital to work in a clinic. For example, she says that she no longer even had an appetite. This has to be an exaggeration, right? Comments appreciated.
