That was my worst job, too, but I worked it one entire summer in my college years.
I was hired as a "nurse's aide", now called CNA's. I worked the 7 am -3 pm shift, I had 6 or 7 non-ambulatory patients that I had to wash, dress, change beds, give breakfast AND lunch to (most had to be hand-fed), and clean up. That's not counting "shower days" and "enema days", both of which are .... well, not pleasant. I had to do charts on them, too, which left almost no time to talk with them, hold their hands, just BE KIND to them.
It was summer, hot (no air conditioning, since the patients were always cold), and I made $2.00 an hour.
It was a horribly difficult but emotionally rewarding job. I learned a great deal from the experience. Later, when I had five family octogenarians in nursing homes at one time, and I knew what to look out for.
Because of that, I've had Long Term Care Insurance for myself since I was 32.
Ironically, a few years ago, I landed a job as a Director of HR in a nursing home. Learned a lot more THERE, until I was fired by the nutjob CEO for not being her "yes girl".
My nursing home experiences have made me save a lot of money for my old age!
