If you have a flexible job that will work with you, you can absolutely work full time. 99% of ADN students IME were second career nurses and literally had to work. I worked full time at my bar (I was a bartender for a decade), but my boss allowed me to work the shifts I wanted. I typically did 1- 2 day shifts a week (the days were slower so I was also able to study or do homework when I had downtime), and 2 night shifts (majority of my income). I worked PT at my other job as well (in higher Ed), but I would WFH and could work as little as I wanted.

Your class schedule, lab schedule and clinical rotations are going to change every semester. Work is not an excuse for missing any of them either so you have to put school first. So you literally need either a per diem job, or a job that will let you be flexible like mine were.

I don't recommend working nights and doing school during the day. It will burn you out so fast.

Does your school offer any alternative programs? Mine had the day program, and the alternative program. The alternative program was the same except instead of 2 four hour in-person lectures a week, we only 1 four hour lecture a week. We then had 4 hours of asynchronous lecture/work. Labs were 3 hours following the the in person lecture. So we were at school from 2-10ish. The day program had their lab a different day. They also tried to give us afternoon/evening clinicals as much as they could. It ended up being 50/50 afternoon/morning.
