. Being a CNA personally is one of the best things i have chose to do career wise. I love the work environment and the work I get to experience while working with older people. The downfalls of being a CNA which could be the mentally challenging part would be, when you get attached to a resident. Which its hard not to, your taking care of them all the time and constantly helping them get into bed, brushing their teeth, washing their hair, and so much more. Then they end up passing away and you have to take care of the post mortem cares then have to help the family process the loss of the loved one. The physically challenging part is having to lift 150+ pound people. If they are over a certain weight we get to use a lift to get them into bed easier. Being a CNA you work long exhausting hours because, CNA’s are always needed. Most of the nursing homes you’ll goto will be understaffed with CNA’s. Overall being a CNA takes a lot of physical work but it also requires you yo be mentally as strong.
