Maybe I'm just built different because c-diff doesn't affect me that much. For me, it's melena, because I literally still smell it for hours after my shift has ended.
Also, while maybe not the worst smell, one of the somehow more disturbing ones was when an intestinal blockage patient belched and it smelled like a fart... which basically it was.
Never, ever become a nurse's assistant if you can't handle horrible smells :)
This cannot be overstated. It can be rough. It's important to know what you're getting into. The worst places I've been have CNAs that are not cut out for the job, and straight up hide during shifts to push the gross/arduous tasks to already heavily-burdened nurses. That is no bueno and it ends with burnt out nurses and much worse patient care.
At the same time, good CNAs are an absolute godsend. Literally could not do my job as well as I do without CNAs kicking ass, so much appreciation for you guys.
