Which competency focuses on the concept of public protection and collaboration to improve health care services?

The competency that centers on the concept of public protection and collaboration to improve health care services is indeed service to the public. This competency emphasizes the role of nurses in safeguarding the well-being and safety of the public, ensuring that care provided meets the needs of individuals and communities.

Service to the public reflects a commitment to prioritize patient welfare and coordinate efforts among healthcare professionals to enhance the quality of care. It embodies the responsibility that nurses have to engage with the community, promote health awareness, and work collaboratively across disciplines to address health care challenges effectively. This approach fosters a health care environment focused on public safety and quality service delivery.

In contrast, self-regulation pertains to the nurse's ability to practice independently while adhering to professional standards. Professional responsibility and accountability relate closely to the nurse's obligation to maintain competence and ethical practice within their work. Ethical practice involves adhering to moral principles and frameworks in clinical decision-making. While each of these competencies contributes to the overall goal of improving health care services, service to the public specifically highlights the essential collaborative aspect aimed at protecting and serving the population's health needs, making it the most appropriate choice in this context.
