I'll have to go with those who mentioned cleaning up puke & poo from hospital sheets, when a patient loses it all over the place.
When I was in the hospital, I had a roomie for 2 nights who had kidney failure. Nice, sweet grandma. Well she had trouble controlling her bowels. She kept pooping all over herself. Now remember I am laying about 6 feet from her, separated by a shower-curtain type thingy, with freaking pneumonia. I was having trouble breathing in the first place and they put someone within spitting distance who was pooping all over the place!
I got grandma back though. My first night in, I was so heavily drugged & sedated, I didn't cough much. However the 2nd night... the nurse, who was really cool, told me I had to cough to get the phlegm and mucus to come up & out. So she gave me an expectorant. So, I kept Grandma up most of THAT night coughing up lung cookies the size of my Toyota!
But I remember hearing the nurse come in and make a really awful sound when she saw that yet again, she had to clean up poo'ed sheets of my roomie. I thought to myself, this nurse has a patietn who is pooping herself and me coughing up things so large, they were assigned their own ZIP code.
