Nursing duties are defined by a combination of educational attainment and regulatory frameworks that establish the legal scope of practice.1

Education and Scope of Practice

Nurses typically enter the profession as generalists, often requiring three to four years of university-level education. However, educational pathways vary; for instance, in the United States, one may enter generalist practice via a two-year community college program or a four-year university degree.2

Advanced nursing practice, such as the role of nurse practitioners, requires graduate-level education. These professionals are trained to provide diagnostic and treatment services, assuming responsibilities that exceed those of generalist nurses. Conversely, roles like the practical nurse involve caring for the sick with different training requirements than those of a registered nurse.234

Regulatory Oversight

The legal parameters of nursing are determined by national and state agencies, which set practice standards and codes of ethics. Licensing mechanisms ensure minimal qualifications for entry and continued competence. While centralized health systems often manage licensing nationally, decentralized systems—such as those in the U.S.—delegate this authority to states or provinces.15
