Congratulations, in most cases, it is very difficult for inexperienced CNAs to get a med surg job.
I can tell you this: you will have it a lot easier and better than if you started in a nursing home! Shoot when I started my Med Surg NA job, they gave me like 5 shifts of orientation! My boss asked me if I wanted more, but I told her, "You can keep giving me small assignments with a preceptor - it's nice and I can help everyone out a lot, but I won't really learn any more from it."
I had already had three years in LTC, home health, and a bunch of clinical rotations so it was really easy to pick up.
It will be hard, but new CNA jobs are always hard. You'll do fine.
