Final answer:
In Arizona, a non-licensed individual may only practice nursing in specific cases, such as emergencies or as a visiting nurse for a limited time, and must otherwise obtain licensure by endorsement if they are licensed in another state.
Step-by-step explanation:
A person can practice nursing in Arizona without an Arizona or multistate compact license when the person is a licensed nurse in another state providing services in Arizona for a period of time permitted by law, such as in emergency situations or as a visiting nurse. In non-emergency situations, nurses must apply for licensure by endorsement if they hold a valid nursing license in another state. It is important for nurses to check with the Arizona State Board of Nursing for the most current regulations and requirements.
