My facility is having so much trouble keeping CNAs that they started asking LPNs to come in and work as a CNA. I don't have a problem with this as long as it is a voluntary thing. Now they have had a LPN come in on her regular shift only to find out that she had to work as a CNA. I don't want to work as a CNA. Don't get me wrong, I admire our CNAs and don't mind changing people and helping out, but I don't think I could handle doing it for a 12 hour shift. I have never been a CNA. Any opinions?
