Registered nurses assess patients, administer medications, coordinate treatment plans, educate families, and serve as the connective tissue between physicians, specialists, and the people in their care. The scope of what an RN can legally do varies by state, but the core framework is remarkably consistent: a systematic cycle of assessment, diagnosis, planning, intervention, and evaluation that guides every patient encounter. Where RNs work, what they earn, and how far their responsibilities stretch depends on setting, education level, and specialization, and the range is wider than most people outside healthcare realize.
Core Duties and the Nursing Process
Every RN’s clinical work is built around a structured method known as the nursing process, a five-step cycle that serves as the standard approach to individualized, holistic patient care.1Heliyon. Pooled estimate of nursing process implementation and its associated factors in Ethiopia: A systematic review and meta-analysis In practice, that looks something like this: the nurse first assesses the patient, gathering vitals, reviewing history, and noting symptoms. Next comes a nursing diagnosis, which is distinct from a medical diagnosis and focuses on the patient’s response to their health condition. From there, the nurse develops a care plan, carries out interventions (anything from administering IV fluids to teaching a patient how to manage a wound at home), and then evaluates whether those interventions worked. If they didn’t, the cycle starts over.
Beyond this structured framework, RNs perform a long list of hands-on tasks every shift. These include starting and monitoring IV lines, drawing blood, administering medications (oral, injectable, and intravenous), managing ventilators and other life-support equipment, documenting everything in the electronic health record, and communicating changes in patient status to physicians and the broader care team. In ambulatory and community settings, common RN activities include health assessments, behavioral health screenings, and telehealth visits.2PubMed.

Delegation and Scope of Practice
One of the most important and least understood parts of an RN’s job is delegation. RNs routinely supervise licensed practical nurses (LPNs) and unlicensed assistive personnel like certified nursing assistants (CNAs). When deciding what tasks to hand off, experienced RNs weigh scope-of-practice regulations, the skill level of the person receiving the task, and the stability of the patient. A director of nursing in one study described her approach as starting with regulations, then evaluating the experience and confidence of individual staff members.3PubMed Central. Delegation in Long-term Care: Scope of practice or job description?
This matters because poor delegation decisions carry real risk. An RN who assigns a task outside an aide’s scope of practice can face disciplinary action from the state board. At the same time, an RN who tries to do everything personally burns out faster and spends less time on the high-level clinical thinking that only a licensed nurse can provide. The skill is knowing what to hold onto (assessments, care planning, patient education, medication administration via certain routes) and what can safely be shared (vital signs, hygiene assistance, basic mobility support).
Where RNs Work
Hospitals remain the largest employer of registered nurses, but the profession has expanded well beyond the bedside. Here are the most common settings and what the work looks like in each.
- Acute care hospitals: This includes medical-surgical floors, emergency departments, operating rooms, and intensive care units. ICU nurses play a specialized role that goes beyond standard bedside care. Research into ICU nurses on medical emergency teams found their central function is keeping patients safe through systematic assessment, critical thinking, prioritizing care, and directing the team’s response.4PubMed Central. Remote patient triage: Shifting toward safer telehealth practice – Section: Background
- Ambulatory and outpatient clinics: RNs in these settings spend more time on health screenings, chronic disease management, patient education, and coordinating referrals. In medically underserved communities, RN dyads have performed thousands of patient visits spanning at least 15 distinct nursing role categories.2PubMed. Nursing roles and responsibilities conducted by registered nurse/BSN student dyads across ambulatory clinical sites in medically underserved communities
- Home health and palliative care: Home care nurses operate with a degree of autonomy that hospital nurses rarely experience. They make complex decisions about treatment in the patient’s home, often navigating ethical gray areas around end-of-life care. Research on home care nurses in palliative settings found they frequently feel caught between clinical guidelines and personal values, while also managing the blurry boundaries of their role when patients are ambivalent about life-and-death decisions.5PubMed Central. Remote patient triage: Shifting toward safer telehealth practice
- Long-term care and nursing facilities: RNs here tend to serve in supervisory and care-coordination roles, overseeing LPNs and CNAs who provide the bulk of direct daily care.
- Schools, correctional facilities, and public health departments: These settings involve more independent practice, often with the RN as the only licensed healthcare provider on site.
The Telehealth Frontier
Virtual care has become a permanent part of the RN landscape. Telephone triage lines and virtual urgent-care platforms rely heavily on registered nurses to assess patients remotely and decide whether someone needs to come in for an in-person visit or can be managed with home care advice. A triage protocol is considered essential to prevent underestimation of illness severity and to sort patients to the right level of care.5PubMed Central. Remote patient triage: Shifting toward safer telehealth practice
The work is harder than it sounds. Without being able to physically examine a patient, the nurse relies on decision-support algorithms, their own clinical judgment, and the patient’s self-reported symptoms. Research into remote triage found that while algorithms provide useful structure, effective outcomes depend on the nurse’s ability to interpret those recommendations in context. Technology, professional training, organizational policies, and patient factors all shape how well the encounter goes.6PubMed. Remote triage and virtual urgent care services: A qualitative assessment of factors that impact triage decisions and outcomes In other words, the software helps, but the nurse’s brain is still doing the real work.
How Education Affects What an RN Can Do
You can become a registered nurse through two main paths: an associate degree in nursing (ADN), which takes about two years, or a bachelor of science in nursing (BSN), which takes four. Both qualify you to sit for the NCLEX-RN licensing exam, and both produce nurses with the same base scope of practice. But the distinction matters more than it might seem.
A landmark study of more than 200 hospitals found that for every ten-percent increase in the proportion of nurses holding a bachelor’s degree, the likelihood of a surgical patient dying within 30 days dropped by about five percent. The same held true for failure-to-rescue rates, which measure how often patients die after developing a complication.7PubMed Central. Educational levels of hospital nurses and surgical patient mortality That finding, adjusted for patient characteristics, hospital size, and nurse experience, helped fuel the push for BSN-prepared nurses that many hospital systems now embrace. Some employers require a BSN for hire; others hire ADN-prepared nurses and require them to complete a BSN within a set number of years.
Beyond the bachelor’s level, RNs can pursue master’s and doctoral degrees to become advanced practice registered nurses (APRNs), which include nurse practitioners, clinical nurse specialists, nurse anesthetists, and nurse midwives. A career pathway model developed through evidence-based policymaking identified three broad competence levels: registered nurse, specialized nurse, and advanced practice nurse.8PubMed. Evidence-informed policymaking: Modelling nurses’ career pathway from registered nurse to advanced practice nurse The jump from RN to APRN is significant: nurse practitioners, for example, can diagnose conditions, prescribe medications, and in many states practice independently without physician oversight.
Licensure and the Nurse Licensure Compact
Every RN must pass the NCLEX-RN and hold a license issued by the state where they practice. Historically, if you wanted to work in a different state, you needed a separate license there. The Nurse Licensure Compact changed that. Developed by the National Council of State Boards of Nursing, the compact allows nurses licensed in their home state to practice in other participating states without obtaining additional licenses, similar to how a driver’s license works.9Nursing Administration Quarterly. Nursing Regulation, the Nurse Licensure Compact, and Nurse Administrators The compact’s goals are to promote nurse mobility, increase access to care, and maintain public protection through uniform licensure requirements.10Journal of Nursing Regulation. Highlights of the Nurse Licensure Compact Survey Findings: Nurses’ Needs, Experiences, and Views
As of recent years, over 40 states have adopted the compact. But does it actually work? Research on the enhanced version of the compact found no statistically significant effect on interstate migration, but it did find that adoption was associated with a meaningful reduction in the share of licensed nurses who were not employed in nursing, an effect that strengthened over time.11Health Affairs Scholar. Effects of the enhanced nurse licensure compact on interstate mobility and nursing employment The compact may not be driving nurses to move across state lines in large numbers, but it does seem to be pulling licensed nurses back into the workforce who had drifted away.
RN Pay and What Drives It
The median annual salary for registered nurses in the United States hovers around $86,000 according to the Bureau of Labor Statistics, though that number masks enormous variation. Geography is the single biggest factor. Nurses in high-cost states like California and Hawaii can earn well above $120,000, while those in lower-cost states may earn closer to $60,000. Research on spatial wage differentials in nursing has demonstrated that the competitiveness of nursing pay in a given local labor market has a strong effect on the ability of healthcare systems to attract and retain nurses. When pay falls below what comparable workers earn locally, vacancy rates climb.12PubMed Central. Geographically differentiated pay in the labour market for nurses
Specialty and setting also matter. ICU and emergency department nurses typically earn more than those on general medical-surgical floors. Travel nurses, who take short-term contracts in areas with staffing shortages, saw their compensation surge during COVID-19. Research on the travel nursing market found that the number of available jobs increased far more than compensation did, suggesting a highly elastic labor supply: nurses were willing to pick up extra contracts without needing massive pay bumps, partly because they were also willing to travel longer distances when pay rose even modestly.13National Bureau of Economic Research. When Workers Travel: Nursing Supply During COVID-19 Surges
Unionization has a measurable but modest effect on RN wages. A scoping review covering nearly 50 years of research found that union wage premiums for nurses were small. Evidence on other nurse outcomes like job satisfaction and retention was limited and mixed, though unionization was associated with improvements in many patient outcomes studied.14PubMed. Nursing unions: A scoping review of outcomes for employees, patients, and administrators
Staffing Ratios and Patient Outcomes
Few topics in nursing generate more debate than mandated nurse-to-patient ratios. California was the first state to implement them, and the early results were ambiguous. Assessments of the mandate’s impact on patient falls and pressure ulcers did not reveal significant changes despite existing research linking nurse staffing to those outcomes.15PubMed. Impact of California’s licensed nurse-patient ratios on unit-level nurse staffing and patient outcomes A follow-up comparison of pre- and post-regulation outcomes similarly found that anticipated improvements in nursing-sensitive patient outcomes were not observed.16PubMed. Mandated nurse staffing ratios in California: a comparison of staffing and nursing-sensitive outcomes pre- and postregulation
The picture got more encouraging with data from Australia. A large multicentre study in Queensland found that hospitals implementing a staffing ratio policy saw mortality drop significantly compared to baseline, while comparison hospitals without the policy did not see the same improvement. Readmissions increased at comparison hospitals but held steady at intervention hospitals. And the financial math worked out: the costs avoided through fewer readmissions and shorter hospital stays were more than twice the cost of hiring additional nurses.17The Lancet. Evaluation of a hospital nurse-to-patient staffing ratio policy in Queensland, Australia: a multicentre prospective panel study That study also found that improving staffing by one patient per nurse produced measurable reductions in mortality, readmissions, and length of stay. The takeaway is that mandated ratios can work, but the magnitude of benefit likely depends on how much staffing actually changes at the ground level.
The Physical and Emotional Toll
Nursing is physically demanding work. Musculoskeletal injuries are more common among nurses than in many other occupational groups.18PubMed. Interventions to prevent and reduce the impact of musculoskeletal injuries among nurses: A systematic review The biggest culprits are manual patient lifting and repositioning, especially with overweight and obese patients. Common injuries include low back pain, sprains, strains, and shoulder and knee problems.19PubMed. Work-related musculoskeletal risks associated with nurses and nursing assistants handling overweight and obese patients: A literature review Mechanical lifting devices help, but modeling suggests that even in the best-case scenario, their use only reduces low back pain prevalence slightly. Complete elimination of manual lifting would reduce injury claims more substantially, but achieving that in real-world clinical settings is extremely difficult.20Occupational and Environmental Medicine. Assessment of the impact of lifting device use on low back pain and musculoskeletal injury claims among nurses
The emotional toll has received intense attention since the pandemic. A synthesis of recent meta-analyses found that nurse burnout during COVID-19 ranged between 30 and 50 percent.21PubMed Central. From Burnout to Resilience: Addressing Moral Injury in Nursing Through Organizational Innovation in the Post-Pandemic Era A study in a chronic care hospital found that half of nurses reported high emotional exhaustion.22PubMed Central. Burnout and Moral Injury in Healthcare Workers: An Observational Study in a Romanian Chronic Care Hospital The problem has not resolved itself with time. A time-series analysis of RNs found that burnout and moral injury levels increased over the first six months of the study period, with no significant improvement over the next twelve months.23JONA: The Journal of Nursing Administration. Resilience, Moral Injury, and Burnout Among RNs: A Time-Series Analysis This is not a crisis that ended when hospital COVID wards emptied out. Burnout has become structural.
How RNs Communicate With the Rest of the Team
One of the less visible but most consequential parts of an RN’s job is structured communication with physicians and other providers. The most widely used framework for this is SBAR, which stands for Situation, Background, Assessment, and Recommendation. It is designed to make clinical handoffs crisp and reliable, reducing the chance that critical information gets lost.24PubMed Central. Facilitating effective communication through the adoption of SBAR tool in medical training
The evidence that this framework saves lives is direct. A pre-and-post intervention study found that after SBAR implementation, all four elements were documented more frequently during serious adverse events, and unexpected deaths dropped from roughly 1 per 1,000 admissions to about 0.3 per 1,000.25PubMed. SBAR improves nurse-physician communication and reduces unexpected death: a pre and post intervention study Unplanned ICU admissions actually went up after implementation, which sounds bad until you realize it means nurses were catching deteriorating patients earlier and escalating care before those patients coded on the floor. That shift from reactive to proactive is exactly what better communication tools are supposed to produce.
Workforce Diversity and Representation
The RN workforce has grown more diverse over the past decade, but significant gaps remain. An analysis using national survey data found that while the proportion of underrepresented minority RNs grew significantly between 2008 and 2018, unequal representation persisted across the ranks of the profession. Latino/a nurses were the only underrepresented minority group demonstrating proportional gains in the advanced practice workforce.26PubMed Central. Workforce Trends of Underrepresented Minority Nurses in the United States Over the Last Decade: Progress Towards Equal Representation? The pattern suggests that while nursing schools have become more diverse at the entry level, the pipeline narrows as nurses move into higher-credentialed and better-compensated roles.
This matters for patient care, not just workforce equity. Research consistently links a diverse nursing workforce to improved access, quality of care, and outcomes for underserved populations.27Journal of Nursing Regulation. The Registered Nurse Workforce: Examining Nurses’ Practice Patterns, Workloads, and Burnout by Race and Ethnicity When nurses share cultural backgrounds and language with patients, communication tends to be more effective, health literacy gaps shrink, and trust comes more easily. The profession recognizes this as a priority, but progress at the advanced-practice level has been slow.
Non-Clinical and Informatics Roles
Not every RN works at the bedside. Nursing informatics is a growing field where RNs apply their clinical knowledge to the design, implementation, and optimization of health information systems. These nurses help build the electronic health records, clinical decision-support tools, and data dashboards that frontline nurses use every day. Early work defining informatics competencies for nurses identified four distinct skill levels, emphasizing that the field requires far more than computer proficiency; it demands knowledge of clinical workflows, data integrity, and patient safety principles.28PubMed Central. Informatics competencies for nurses at four levels of practice
Other non-clinical roles include nurse educators who teach in academic programs, quality improvement specialists who analyze hospital data to reduce errors, case managers who coordinate care across settings and insurers, legal nurse consultants who review medical records for law firms, and nurse researchers who design and run clinical studies. The RN license serves as a foundation that opens doors well beyond direct patient care, which is part of why the profession continues to attract people with varied career ambitions.
