When I was a PCA, I was assisting the RN change a dressing or something. Anyway, you guys know how when you have gloves on or something nasty is on your gloves...your nose always starts to itch? Well, I proceeded to scratch my nose with the non-gloved part of my arm...apparently my mouth was opened at the same time...I tasted something salty, but didn't really think about it at the time. Next, I looked down at my glove and there was blood on the glove...UUUGGGHHH!!!!
