I am thinking about taking a CNA class to see if I would like being a nurse. I do enjoy helping people including the elderly. But is this job really hard? Do you use lifts to move patients in Nursing homes and hospitals? I do have neck and back pain sometimes due to needing a breasts reduction. So I would be wearing a back and possibly a neck brace while working. Also are you allowed to wear masks and goggles to protect you from germs? I've been told that some patients will try to spit and throw feces on you. Which is why I will definitely want to wear a masks and goggles.
