Which healthcare worker is required to earn a license to practice their profession?

A physician is required to earn a license to practice their profession because they have a significant responsibility for diagnosing and treating patients. The licensing process is rigorous and typically includes completing a medical degree, passing comprehensive board examinations, and fulfilling residency training requirements. This ensures that physicians have the necessary education, skills, and ethical standards to provide safe and effective medical care.

The other healthcare workers listed also have important roles in patient care, but their licensing requirements differ. While nurses, pharmacists, and others may also need to be licensed to practice, the specific question indicates that the physician’s licensing requirements are particularly stringent and foundational for their ability to manage complex health conditions.
