Nursing as a complex system engages nurse at the heart of health care functions fostering their indispensable nature especially in the public health environment. This paper is aimed at describing the Altruistic Care Theory of Nursing (ACTON), addressing the intricacy of nursing practice in health equity and health inequity matters. Nursing that is delivered as altruistic care can be performed by nurses through "internalizing and intervening behaviors" which include reflective processes that transcend the traditional health care. "Nursing Interventions" are multifaceted and inclusive of individualized care. Altruistic Care Theory in Nursing may prove advantageous in addressing health inequity issues through human to human interactions with clients, co-workers, and other members of the health care team, and participating in collaborative and informed engagements.
