Final answer:
The American Nurses Association is the organization that lobbies for the interests of nurses at state and federal levels, advocating for their role, economic interests, and healthcare improvements.
Step-by-step explanation:
The group that lobbies at the state and federal levels for the advancement of nurses' role, economic interests, and health care is the American Nurses Association (ANA). The ANA is a professional organization representing the interests of the nation's entire registered nurse population. Other groups such as State Boards of Nursing are regulatory bodies responsible for the licensure and practice standards of nurses within a particular state, whereas the American Hospital Association represents hospitals and healthcare networks.
The National Student Nurses Association is aimed at nurturing the professional growth of nursing students. The ANA focuses on advancing the nursing profession by fostering high standards of nursing practice, promoting the rights of nurses in the workplace, advocating on health care issues, and lobbying Congress and regulatory agencies about health care issues affecting nurses and the public.
