MO Private Practice RN to work in Hospital (on behalf of priv. pract)

Hello everyone.

Is anyone in Missouri working for a private practice group as an RN who's practice rounds in any hospital? If so what are you allowed to do in the hospital working for your MD or pracitice without being a hospital employee?

Any input on any part of this will be helpful.

Thanks!
This is happening in Maryland, but the nurses are NPs and able to prescribe, do orders under their MDs guidance. They do not partake in the hospital regulations that apply to nursing staff who are employed by the hospital. Your employer will be the MD??
