I work PRN at a hospice for 13/hr. I actually spend most of my time in the office helping with administrative/clerical/busywork tasks. It really helps to prevent burn-out with regular CNA work. I recommend it for anyone who is interested.
I used to work in a memory care unit too, 8 hrs/day, and it was awful. Afternoon shift pushed my sleep schedule way back, the manual labor was never-ending, and co-workers were mean gossips. Quit after 3 months.
As for how it reflects in apps, I have no idea lol. I haven't even gone to an interview yet. But I hope it reflects well!
Honestly though, I'm not sure if there's a true advantage for schools that stress academics. As much as being a CNA has shown me about the patient experience and basic nursing skills, I haven't been able to publish a paper, show leadership, promote social justice, start a business, cure a disease, or get any other super gold stars. I don't know if some adcoms will dismiss the experience as routine booty-wiping. That's my fear.
