Registered nurses provide hands-on patient care, coordinate treatments, educate families, and serve as the primary point of contact between patients and the rest of the healthcare team. They work in hospitals, clinics, schools, and private homes, with responsibilities that shift depending on the setting. The median annual salary for registered nurses was $93,600 in May 2024, and employment is projected to grow 5 percent from 2024 to 2034.
Core Clinical Responsibilities
The day-to-day work of an RN centers on direct patient care. That includes performing physical exams, recording observations about a patient’s health, administering medications and other treatments, assisting with diagnostic tests, and operating medical equipment. These tasks happen continuously throughout a shift, not as isolated events. A nurse on a general medical-surgical floor might care for four to eight patients at a time, cycling through assessments, medication rounds, and documentation for each one.
Behind every clinical task is a structured thinking process nurses follow called the nursing process. It has five steps: assessment, diagnosis, planning, implementation, and evaluation. During assessment, the nurse collects data about a patient’s physical condition alongside psychological, social, spiritual, and lifestyle factors. From there, the nurse forms a clinical judgment about how the patient is responding to their health condition, sets measurable goals (like getting out of bed three times a day or managing pain through medication adjustments), carries out the care plan, and continuously evaluates whether it’s working. If it’s not, the plan gets modified. This cycle repeats throughout the patient’s stay.
Medication Safety
Administering medications is one of the highest-stakes parts of a nurse’s job. Nurses verify that each medication is appropriate for the patient, confirm dosages, check for contraindications, and document everything. For high-alert medications, additional safeguards kick in: independent double checks by a second qualified staff member, standardized labeling on IV bags and tubing, and calibrated infusion pumps to control delivery rates.
When something goes wrong, nurses are often the first to respond. If a patient shows signs of a toxic reaction, for example, the nurse can activate a rapid response call, stop the infusion, monitor vital signs including oxygen levels, and administer an antidote using pre-approved standing orders before the physician arrives. This kind of independent clinical judgment is a core part of what separates RNs from other support staff.
Patient Education and Discharge Planning
Nurses don’t just treat patients in the moment. They prepare them to manage their health after they leave. Discharge planning starts early in a hospital stay, not on the last day, and nurses drive most of it. They teach patients and families about five key areas to prevent problems at home: what daily life will look like during recovery, how to take each medication (including purpose, dosage, and side effects), what warning signs to watch for, what test results mean, and which follow-up appointments to keep.
Good patient education relies on plain language and repetition. Nurses break information into small chunks, revisit important points throughout the stay, and use a technique called “teach back,” where they ask the patient to repeat instructions in their own words to confirm understanding. They also identify which family members or friends will be providing care at home and include those people in conversations early. The goal is making sure patients and caregivers feel competent and confident before they walk out the door.
Patient Advocacy
Advocacy is baked into the profession’s definition. The American Nurses Association describes nursing as the protection, promotion, and optimization of health, the prevention of illness and injury, and advocacy in the care of individuals, families, and communities. In practice, this means nurses listen to a patient’s goals and preferences, ask open-ended questions to surface concerns, and make sure the care team accounts for what the patient actually wants. They push for family involvement, encourage patients to write down questions, and schedule dedicated conversations about care plans rather than rushing through them during rounds.
Where Registered Nurses Work
Hospitals are the most common setting, but they’re far from the only one. In outpatient clinics, RNs support providers by triaging patient phone calls, coordinating daily patient flow, running infusion therapy sessions, and managing population health campaigns. Some serve as vaccine coordinators, overseeing inventory, storage, and compliance with local health department programs. In pediatric clinics, nurses assess symptoms over the phone, determine urgency, and document findings in electronic medical records.
Outside of clinical facilities, nurses work in schools, corporate wellness programs, home health agencies, and public health departments. Home health nurses provide one-on-one care for patients recovering from surgery or managing chronic conditions, often with a level of independence that hospital nurses don’t have. School nurses handle everything from managing students’ chronic conditions like asthma and diabetes to conducting vision screenings and responding to injuries.
How Hospital Specialties Differ
The intensity and pace of nursing work varies dramatically by unit. On a general medical-surgical floor, nurses care for patients with a wide variety of diagnoses, from post-operative recovery to infections to chronic disease flare-ups. Patient loads run from four to eight, and the work emphasizes breadth. These floors are often where new graduates start because the variety builds a strong clinical foundation.
Critical care nursing is a different world. ICU nurses care for the most unstable patients in the hospital, typically handling just one to three patients at a time. Only RNs (not LPNs) can work in these settings. Shifts are almost always 12 hours to minimize handoffs between caregivers, since even small communication gaps can be dangerous with critically ill patients. The equipment is more complex, the decision-making is faster, and the margin for error is narrower.
Education and Licensing Requirements
There are two main educational paths to becoming an RN. An Associate Degree in Nursing takes two to three years and qualifies you to sit for the licensing exam. A Bachelor of Science in Nursing takes about four years but opens more career doors. Many hospitals now require new hires to hold at least a BSN, and most advanced certifications and graduate programs require one as well. If you start with an ADN, your credits typically transfer toward a BSN later, which makes it a common stepping-stone approach.
Regardless of which degree you earn, you must pass the NCLEX-RN, a national licensing exam that verifies you have the knowledge and skills to practice safely as an entry-level nurse. Once you pass, your state issues your license and you can begin working. Licensure is state-based, with each state’s nurse practice act defining the legal boundaries of what an RN can do independently. These boundaries vary somewhat from state to state, so a procedure an RN performs routinely in one state may require additional certification or physician oversight in another.
Scope of Practice
An RN’s legal scope of practice is defined in two layers. First, the state legislature passes a nurse practice act. Then regulatory bodies create rules and regulations that fill in the details. Together, these documents outline what nurses can and cannot do, who they can treat, and what professional standards they must meet. For nurses working in a recognized specialty like critical care, oncology, or pediatrics, additional specialty standards describe the specific competencies, professional boundaries, and expected behaviors for that role. These standards serve as a reference not just for nurses but for employers, educators, and regulators as well.
