The American Nurses Association (2012) defines nursing as "the protection, promotion, and optimization of health and abilities, prevention of illness and injury, alleviation of suffering through the diagnosis and treatment of human response, and advocacy in the care of individuals, families, communities, and populations" (para. 25a).
This definition address's the metaparadigm theories of nursing by person/health, "provision of a caring relationship that facilitates health and healing"; health/environment, "attention to the range of human experiences and responses to health and illness within the physical and social environments"; and nursing practice, "application of scientific knowledge to the processes of diagnosis and treatment throughout the use of judgment and critical thinking" (para. 25b).
