Registered Nurse Job Description

A registered nurse is the licensed clinician who owns the patient between provider visits. The physician or nurse practitioner writes the orders; the RN turns them into an hour-by-hour plan, watches how the patient responds, and decides when something has changed enough to call back. That judgment, exercised across a full shift and passed along at the end of it, is the center of the job.

The work runs on the nursing process: assess, identify the nursing problem, plan, carry out, evaluate. On an inpatient unit that starts with a head-to-toe assessment, a review of active orders and new labs, and a medication pass checked against the medication administration record, with a barcode scan at the bedside before anything goes into the patient. Between the scheduled tasks come the unscheduled ones: a post-op patient whose pain is climbing, a telemetry alarm, a daughter who wants an update, an admission arriving from the emergency department, a discharge that needs teaching finished before transport shows up.

Documentation runs through the whole shift. Assessments, interventions, intake and output, wound measurements and patient education all land in the electronic health record, in systems such as Epic, Oracle Health or MEDITECH. The chart is both the legal record and the handoff tool for the next nurse. Structured formats such as SBAR (situation, background, assessment, recommendation) keep shift reports and calls to physicians short and specific.

Setting shapes the work more than the title does. Critical care nurses titrate vasoactive drips, manage ventilated patients alongside respiratory therapists and read hemodynamic monitoring continuously. Emergency nurses triage under time pressure and stabilize patients before anyone knows the diagnosis. Perioperative nurses work as circulators or scrub nurses, guarding the sterile field and running instrument and sponge counts. Labor and delivery nurses monitor mother and fetus together and must be ready when a routine labor turns urgent. Outside the hospital, ambulatory and clinic RNs handle phone triage, injections, chronic disease follow-up and care coordination. Home health nurses do assessments, wound care and medication reconciliation in patients' houses, usually without a colleague down the hall. School nurses manage medications, allergies, asthma and diabetes plans for an entire student body.

Across all of these settings the RN supervises and delegates. Licensed practical nurses and nursing assistants take on tasks the RN assigns within state scope of practice, but the RN keeps accountability for the assessment and the plan. Charge nurses add staffing, bed flow and escalation calls on top of their own patients.

The job is physical and emotional at once. Bedside nurses spend much of a shift on their feet, reposition and transfer patients, and absorb the fear and grief of people on some of the worst days of their lives. Good nurses build habits to manage all of it: clustering care, protecting a few minutes to chart, and asking for help early rather than late.

Every RN needs a state license, and every license runs through the NCLEX-RN, the licensing exam developed by the National Council of State Boards of Nursing (NCSBN). To sit for it, a candidate completes an approved prelicensure program. BLS describes three education paths: a bachelor's degree in nursing, an associate degree in nursing, or a diploma from an approved nursing program.

Choosing a program. The associate degree is usually the fastest route to licensure, typically two to three years at a community college. The bachelor of science in nursing typically takes four years and adds public health, leadership and research coursework, and it is the usual stepping stone to graduate study and management. Career changers who already hold a bachelor's degree in another field can look at accelerated BSN programs, which the American Association of Colleges of Nursing says take between 11 and 18 months to complete, including prerequisites. Associate-prepared nurses can finish an RN-to-BSN program while working.

The exam. The NCLEX-RN is a computerized adaptive test. NCSBN launched the Next Generation NCLEX exams on April 1, 2023, as an enhancement of the existing NCLEX exams. Under the 2026 NCLEX-RN Test Plan, in effect from April 1, 2026 through March 31, 2029, candidates answer a minimum of 85 items and a maximum of 150 within a five-hour window. The best preparation is a program with strong clinical placements plus a structured question bank in the final semester.

Life support and early credentials. Plan on holding a Basic Life Support card, such as the American Heart Association course, from the first day. For critical care, emergency or procedural work, plan on adding Advanced Cardiovascular Life Support (American Heart Association); for pediatrics, add Pediatric Advanced Life Support (American Heart Association).

Specialty certification. BLS notes that nurses may become certified through professional associations in specific areas, and that certification is usually voluntary. Specialty credentials worth considering after a year or two in a specialty include the CCRN for critical care (AACN Certification Corporation), the CEN for emergency nursing (Board of Certification for Emergency Nursing), the CMSRN for medical-surgical nursing (Medical-Surgical Nursing Certification Board), the OCN for oncology (Oncology Nursing Certification Corporation) and the CNOR for perioperative nursing (Competency & Credentialing Institute). Each board sets its own practice-hour requirement.

Skills that matter on the floor. Systematic physical assessment, medication math, IV starts and central line care, telemetry rhythm recognition, wound care, fluency in an EHR such as Epic, clean delegation, and calm communication with frightened families. A new graduate's first year typically runs through a preceptored orientation or a formal nurse residency program, and a year or two of medical-surgical or step-down experience is typical guidance before moving to critical care or emergency nursing.

Beyond the bedside. A master's or doctoral degree opens advanced practice roles such as nurse practitioner, nurse anesthetist, nurse-midwife and clinical nurse specialist, along with informatics, education and executive leadership tracks.

BLS counted 3,465,400 RN jobs in 2025 and projects employment to grow 6 percent from 2025 to 2035, faster than the average for all occupations. It expects about 180,800 openings a year over the decade, many of them from the need to replace nurses who move into other occupations or leave the labor force, for example to retire.

Hospitals are the biggest employer. Per BLS, state, local and private hospitals employed 59 percent of RNs in 2025, ambulatory healthcare services 19 percent, nursing and residential care facilities 6 percent, and government 5 percent. That spread means the same license works in clinics, physician practices, long-term care and public agencies, not only on inpatient units.

Retention is the pressure point. NCSBN's 2024 National Nursing Workforce Study, which surveyed 800,000 nurses, found that more than 138,000 nurses had left the workforce since 2022, citing stress, burnout and retirement as key reasons. In the same study, 39.9% of RNs reported an intent to leave the workforce or retire within the next five years. NCSBN itself describes elevated intent to leave as more informative than predictive, so treat the figure as a signal, not a forecast. For a nurse choosing an employer, the practical takeaway is to ask about staffing, turnover, orientation length and float policy as directly as about pay.

Artificial intelligence is the newest variable. On May 5, 2026, the American Nurses Association published consensus findings from its inaugural AI in Nursing Practice Think Tank, convened on April 22, 2026, on how AI is already affecting nursing. The report lists risks that bedside nurses will recognize: erosion of professional judgment through overreliance on AI outputs, unclear accountability and liability when AI tools influence care decisions, algorithmic bias that could worsen patient safety and disparities, and increased cognitive burden from poorly implemented tools. Its near-term actions include nurse-led guardrails, a nursing AI playbook, and AI literacy and competence. For working RNs that points to a concrete skill: knowing how a sepsis alert, a deterioration score or a drafted note was produced well enough to challenge it.

Career movement inside nursing takes several forms. Staff nurses can step into charge nurse, nurse manager and director roles on the administrative side, or climb a clinical ladder that rewards expertise without a management title. Lateral moves into case management, utilization review, infection prevention, informatics, quality, education and telehealth triage use the same license.

For someone entering the field now, the profile is projected growth, a license that travels across compact states, and many routes away from the bedside without leaving nursing, paired with a workforce that is telling its regulators it is tired. Choosing a first employer carefully is as important as choosing a program.

Dear Hiring Manager,

Please consider me for the open staff nurse role on your progressive care unit. I finished my BSN in May, passed the NCLEX-RN on my first attempt, and hold an active state license along with current BLS and ACLS cards.

My capstone placement was on a cardiac step-down unit, where my preceptor gradually handed me a full assignment. By the end of the rotation I was running the morning medication pass, completing admission assessments, and giving bedside report to the night nurse without prompting. The skill I worked hardest on was reading the monitor in context. One evening a patient on a heparin drip went into a new rapid rhythm while his blood pressure held steady, and I recognized the change, pulled a strip, checked his latest labs, and paged the provider with a concise SBAR before the alarm fatigue on the unit could bury it. The rate-control order came back within minutes, and my preceptor used the call as a teaching example for the other students.

Before nursing school I spent three years as a pharmacy technician at a community hospital. That job taught me to treat a medication order as something to verify, not just carry out, and it made me comfortable calling a prescriber with a question.

Your unit's twelve-week orientation and its support for nurses working toward the PCCN are the main reasons I am applying. I want to build a strong cardiac foundation here before pursuing critical care.

I can work day or night rotations, including weekends, and can start after a standard two-week notice. Thank you for considering my application.

Sincerely,

[Your Name], BSN, RN
