Which of the following professionals is considered a medical professional according to the provided definitions?

The designation of a medical professional typically requires specific education, training, and licensure that ensures the individual is qualified to provide medical care and services. In this context, a registered nurse fulfills these criteria by holding a degree in nursing and being licensed to practice. Registered nurses undergo rigorous training and must pass a licensing exam, which qualifies them to assess patients, administer medications, and provide comprehensive care in various medical settings. This formal recognition and licensure classify them as medical professionals.

On the other hand, while a licensed tattoo artist, a certified body art technician, and an unregistered health care provider may have skills relevant to body art practices, they do not possess the same level of medical training or official recognition that comes with being a registered nurse. Tattoo artists and certified technicians focus on body art rather than healthcare, and unregistered healthcare providers lack the necessary credentials that constitute being a professional in the medical field.
