Nursing is a professional discipline dedicated to the promotion of health, prevention of illness, and management of acute and chronic conditions. It encompasses the direct care of individuals and populations, involving the assessment of physical and psychosocial status, the planning of interventions, and the implementation of therapeutic measures. The scope of practice requires integrating specialized knowledge in human anatomy, physiology, pathology, and public health sciences to deliver comprehensive, individualized care. Modern nursing emphasizes critical thinking and evidence-based practice, utilizing systematic evaluation to guide care delivery, thereby aiming to restore function, alleviate suffering, and optimize overall patient well-being across various settings, including community, hospital, and home care environments.
