I started out as CNA in nursing home also. Now RN for 17 years.
The work is hard. You want the truth--right? Depending on the facility as far as turnover. But almost all places will be short staffed: have the CNA, who THINKS they run things: and have the Mean nurse. Just do not give up . Keep your chin up. When you get a job with the CNA status stick it out. Always remember to try to be part of the solution, not the problem.
As far as the patients. Most are great. Appreciate what you do..and the familys will too. There will be the occassional pt, who thinks you owe them everything right then, when they want it. And there will be the family who thinks that there mom's poop doesn't stink. But this happens in the real world too.
Comparing CNA work in hospital vs. Nursing home. The nursing home is better. You get to build relationships with families and patients. The appreciation is better. And you get to know the ins and outs of your patients. I depend on my cna's to be my eyes and ears. They see the patient numerous times a day. They know when there is a change sooner than I do----communicate with your nurse. Work as a team. You are both there for the patient and for each other. A nurse who is willing to help clean a poopy pt is a lifelong friend to the busy cna. And the CNA who is willing to get the vitals right then and check on Mr so-so is a nurses best friend.
Good Luck you are in a wonderful field.
