Registered nurses play a key role in improving and maintaining the mental, physical and behavioral health and well-being of people, families, communities, and populations. They support and enable people at all stages of life and in all care settings to make informed choices about how to manage health challenges in order to maximise their quality of life and improve health outcomes. They are actively involved in the prevention of and protection against disease and ill health and engage in public health, community development, and global health agendas, and in the reduction of health inequalities.
