Registered nurses provide hands-on care to patients, assess their health, administer treatments and medications, monitor recovery, and work with doctors and other healthcare professionals to develop and manage care plans. RNs also educate patients and families and use electronic health records, digital monitoring systems, and increasingly AI-supported healthcare technology as part of modern nursing practice.
Plan on about 4 years of postsecondary education for the most widely recognized RN pathway. Complete an approved nursing program, typically a Bachelor of Science in Nursing (BSN/BScN), including classroom study, laboratory work, and supervised clinical experience. You must then pass the required nursing licensing examination and register with the nursing regulatory body where you plan to work.
Registered nurses work in hospitals, clinics, doctors' offices, long-term care, community health, schools, home healthcare, and other healthcare settings. Some work in specialized areas such as emergency, intensive care, surgery, pediatrics, mental health, or critical care. Nurses may work days, nights, weekends, or rotating shifts, depending on their role. Modern RNs also work extensively with electronic health records, digital patient-monitoring equipment, telehealth, and other healthcare technologies.
Nursing is expected to remain an important and in-demand career globally. An aging population, longer life expectancy, chronic diseases, and growing healthcare needs are increasing demand for nurses in many parts of the world. The World Health Organization's 2025 nursing report estimates that the world could still face a shortage of about 4.5 million nurses by 2030, despite growth in the global nursing workforce. *Nursing is also becoming more technology-driven. Electronic health records, remote monitoring, telehealth, robotics, data systems, and AI-assisted clinical tools are changing how nurses work. The technology is not replacing the need for nurses; it is changing the skills nurses use.
