Nursing is both an art and a science that focuses on the protection, promotion, and optimization of health and human abilities. It involves the prevention of illness and injury, the alleviation of suffering through the diagnosis and treatment of human response, and advocacy in the care of individuals, families, communities, and populations. As an autonomous profession, nursing blends compassionate patient-centered care with rigorous scientific knowledge.
Global bodies shape how nursing is practiced and understood worldwide. The International Council of Nurses (ICN) defines nursing as encompassing autonomous and collaborative care of individuals of all ages, families, groups, and communities, whether sick or well, in all settings. Similarly, the World Health Organization (WHO) highlights the vital contribution of nurses to universal health coverage and primary healthcare delivery systems.
The nursing metaparadigm defines the four core phenomena that anchor all theoretical nursing frameworks and clinical practice:
A professional nurse integrates specialized knowledge, ethical integrity, and empathy into daily patient interactions. Key roles include serving as a care provider, patient advocate, educator, and communicator. Professional accountability means taking responsibility for one's actions, maintaining competence through continuous learning, and adhering strictly to established codes of ethics.
In Nigeria, nursing practice is regulated by the Nursing and Midwifery Council of Nigeria (NMCN). The scope defines what qualified nurses are educated, authorized, and legally permitted to do. It covers preventive, curative, and rehabilitative care in primary health centers, teaching hospitals, and private clinics. Adhering to the NMCN guidelines safeguards the public against quackery and ensures high standards of professional conduct.
