The Nursing and Midwifery Board of Australia (NMBA) plays a crucial role in ensuring the standards and quality of healthcare services offered by registered nurses in various medical and healthcare settings. The NMBA has developed codes of conduct, standards for practice, and codes of ethics that guide professional practices in nursing and provide quality care and services. The organization's standards and guidelines are based on international covenants, such as the 'International Covenant on Civil and Political Rights' under the authority of the United Nations (UN), as well as publications from the World Health Organization (WHO) and the United Nations Development Program. Additionally, the NMBA ensures that healthcare services in Australia meet the National Safety and Quality Health Service Standards to guarantee ethical and quality service delivery.
