This makes you so mad! i have had the same problem over the past couple years with alot of new girls. The thing is if you complain than you will just end up looking like the big mean pushy cna. The best thing to do is to sit down and talk to the DNS and explain to them that you feel like she may need some training one on one again. even offer to do it on another night when she's not on a assignment so you don't double your work load. Trust me you will look like your going out of your way and it might even help speed her up. if the problem still continues than maybe they will take notice since you brought it to their attention. they will also remember your helpfull positive attitude. good luck!
