What is the primary function of the American Nurses Association (ANA)?

The primary function of the American Nurses Association (ANA) is to advance the nursing profession and advocate for nurses and patients. This encompasses a broad range of activities aimed at improving the quality of care and ensuring that nurses are supported in their professional roles. The ANA works to establish standards for nursing practice, promotes a positive image of nursing, and lobbies for the interests of nurses at various levels of government.

By focusing on advocacy, the ANA empowers nurses to enact change in healthcare settings and ensures that patient care is prioritized. This includes promoting policies that enhance the healthcare system and ensuring that nurses have the tools and resources necessary to provide high-quality care to their patients.

The other options address important aspects of nursing but do not capture the primary role of the ANA as fully. For instance, while developing new nursing theories and conducting research on nursing practices are essential components of nursing's evolution, they are not the main focus of the ANA's mission. Similarly, establishing nursing schools is crucial for training the future workforce, but it falls outside the direct advocacy and professional advancement remit of the ANA.
