The main part is that you have to be caring and patient. As a cna we deal with a lot of different people from everywhere. So compassion and a want to help others will go a long way. As with being a nurse. To become a Cna there is. 3 month class with a state exam at the end of your schooling. Nursing is a bit different. But there are programs and schools that you will attend to help you on your way. You could be a Lvn, or a Rn depending on what’s comfortable for you. I became a Cna because I wanted to help people and to let them know that some one cares. I treat all my residents like their family regardless of the situation. I really love what I do.
