Acute care nurse practitioner roles have been introduced in many countries. The acute care nurse practitioner provides nursing and medical care to meet the complex needs of patients and their families using a holistic, health-centred approach. There are many pressures to adopt a performance framework and execute activities and tasks. Little time may be left to explore domains of advanced practice nursing and develop other forms of knowledge. The primary objective of praxis is to integrate theory, practice and art, and facilitate the recognition and valuing of different types of knowledge through reflection. With this framework, the acute care nurse practitioner assumes the role of clinician and researcher. Praxis can be used to develop the acute care nurse practitioner role as an advanced practice nursing role. A praxis framework permeates all aspects of the acute care nurse practitioner's practice. Praxis influences how relationships are structured with patients, families and colleagues in the work setting. Decision-makers at different levels need to recognize the contribution of praxis in the full development of the acute care nurse practitioner role. Different strategies can be used by educators to assist students and practitioners to develop a praxis framework.
