Need help nursing qualifications for foot care

  1. My mom owns her own foot care business and is looking to hire a new employee. She's been working with my sister, and they are both nail techs and my mom is a CNA. My mom needs to hire someone with a medical background, like a RN, or a CNA with foot care experience.

    So basically, I'm just wonder what are the qualifications for an RN to do senior foot care I'm Washington state?
