@Rose Black,
I don't know what kind of advantages you wanted to know so be little specific when asking questions. It is mostly place (city) and hospital type dependent. At my hospital, new CNAs make $1.38/hour more than the state minimum pay. Also, they get about 10 days/year of paid time off when working as a full time employee. Most of my CNAs went through about 8 weeks of training and their job responsibility includes helping patient with toileting (you gottta wipe their ass and balls frequently), making patients bed, passing water and linens, cleaning medical equipments, transporting patients between wards etc. Basically CNA is a cleaning job and there is little to no room for gaining clinical knowledge out of it. Personally, I would choose some other minimum pay jobs than being CNA at anytime of the day. Oh and finally healthcare in USA is not much different than Nepal. As long as you have a degree you can be doing crap and still get away (yes that includes Doctors too).
