That's a tough job- I did a one month CNA certification one summer and get some hands on experience in college, and I didn't have a single coworker there more than 5 years who didn't have at least one serious injury. The for-profit nursing home couldn't be bothered to provide adequate supplies (I worked 3-11 and literally started my shift by bargaining with the other CNAs on the floor over how to split up the inadequate number of bath towels and fitted sheets for that night, because there certainly couldn't be enough clean linen for everyone scheduled for a shower or bed change). I had 15 patients every shift to move in and out of the dining room, feed, shower each 2x/week, do bed baths on the others, brush teeth, change all the diapers and soiled beds, turn and reposition in beds to stop bedsores, answer call bells, etc. There was also an insane amount of charting on the computer system for each one- I'm talking recording an estimated size of each poop and how many ml of fluid each one drank each day. The back injuries came in because with all this to do, there was no way people were available to help you move patients in the lifts that were supposed to require 2 operators. That includes a literally 600 lb woman would had no other way out of her bed. Most of these patients were demented to some degree and also wandered and got into things. If you think the nurses might help, you are out of your mind (all LPNs, could not give less of a crap- sometimes couldn't be bothered to even give scheduled meds.) I cared about my patients, but what a nightmare. It was a good experience to have before I went to medical school though- I have a very realistic view of what nursing homes will and won't do in terms of prescribed treatments.

Also know that a CNA is NOT an easy $11/hour
