I'm a new NA (= limited experience) so it's really great for me to realize that everyone has things they can't stand! I'm going to go on and get my RN, despite all the people telling me I'm too old, too inexperienced, too much of an old trucker, etc. None of that worries me, but the one thing that has given me pause is ... I HATE NOSEBLEEDS!! Colostomies? I find them interesting. Poop? I worked in daycare for a long time - no prob. Same with pee. Wounds, trachs, etc. are just all too interesting so I forget to even be grossed out. But my deep, dark secret is that I absolutely cannot handle nosebleeds. The one time in my life when I thought I had one (turned out the blood was from the outside of my nose!) I actually threw up! Now THAT has made me wonder about myself. "If I can't handle nosebleeds do I really have what it takes to be a nurse?" So reading these replies is great. I guess we all have our weirdnessses. It's really funny reading what sets us each off. Makes me smile over my chemistry book.
