Which of the following contributions is made by The American Nurses Association (ANA)?

The contribution made by The American Nurses Association (ANA) that is best represented is the provision of a definition of nursing. The ANA plays a significant role in the nursing profession by establishing a clear definition that provides parameters for practice and helps to define what nursing is and what nurses do. This definition is essential for understanding the scope of nursing practice and ensuring that the role of nurses is recognized and valued in healthcare.

The definition of nursing created by the ANA is used as a foundational framework for nursing education, practice, and policy. It helps guide not only nurses in their daily work but also informs the public and other healthcare professionals about the unique contributions nurses make to patient care and the healthcare system as a whole. Thus, recognizing the ANA's role in defining nursing is crucial for both professional development and the promotion of nursing as a vital component of healthcare.
