Final answer:
Occupational licenses protect consumers, promote professional conduct, and verify the scope of practice for practitioners.
Step-by-step explanation:
Occupational licenses play a crucial role in protecting consumers and ensuring professional conduct in various industries, including healthcare. By requiring practitioners to be state licensed, it not only safeguards consumers but also allows individuals to file complaints if needed (option a). Additionally, occupational licenses promote continued competency, ethical practice, and protect occupational therapy (OT) providers in situations where clients argue that certain tasks should be delegated to other professionals (option b). Lastly, state regulatory boards, when making changes to the practice act, can verify and educate clients about new inclusions in the scope of practice, such as dry needling for an OTR in this case (option c).
