Nurses assess patients, administer medications, monitor vital signs, coordinate care across medical teams, and serve as advocates for patients who can’t always speak for themselves. But that short list barely scratches the surface. Nursing spans a wide range of roles, settings, and levels of responsibility, from providing basic bedside care to running independent primary care practices.
What a Typical Day Looks Like
In hospitals, nurses typically work 12-hour shifts, meaning each patient interacts with two primary nursing teams in a 24-hour period. A shift starts with a handoff: the incoming nurse reviews patient records and meets with the outgoing nurse to discuss each patient’s condition, recent changes, and care needs. This handoff is critical because it creates continuity even as personnel rotate throughout the day.
From there, the work is a constant cycle of checking on patients, delivering treatments, and documenting everything. Nurses take vital signs, administer injections, manage wound care, run point-of-care tests like blood clotting checks, adjust medication dosages, and follow up with patients who recently visited the emergency department. In primary care settings, nurses also handle first prenatal visits, lactation support, newborn assessments, and complex medication reviews. Between all of this, they’re charting observations, recording changes in patient behavior, and updating electronic health records so the next team knows exactly where things stand.
Patient Advocacy
One of the most important things nurses do has nothing to do with needles or monitors. Nurses act as the voice for patients who are too sick, too overwhelmed, or too unfamiliar with the medical system to advocate for themselves. In practice, this means communicating a patient’s needs and concerns to physicians, pushing back when a treatment decision doesn’t seem right for a particular patient, and making sure critical information doesn’t fall through the cracks between departments.
As one registered nurse described it in a study on clinical advocacy: “Patient advocacy is about how as a nurse you speak up for your patients to ensure that they get the best.” Another put it more simply: “Being the mouthpiece of the patient.” This role requires judgment. Nurses spend the most continuous time with patients of any provider, which puts them in a unique position to notice changes in condition, spot concerns a physician might miss during a brief visit, and flag problems early.
How Nurses Think Through Patient Care
Nursing isn’t just task execution. Every patient interaction follows a structured decision-making process with five steps: assessment, diagnosis, planning, implementation, and evaluation. During assessment, nurses collect both subjective information (what the patient tells them) and objective data (measurable things like blood pressure, weight, and fluid intake). They then identify nursing diagnoses, which are clinical judgments about how a patient is responding to a health problem. This is distinct from a medical diagnosis. A physician might diagnose pneumonia; a nurse might identify that the patient has impaired breathing and is at risk for dehydration.
From there, nurses build individualized care plans with specific goals, carry out interventions like applying monitoring equipment or administering medications, and then reassess to see whether the plan is working. If it isn’t, they adjust. This cycle can repeat many times during a single shift for a critically ill patient.
The Technology Nurses Use
Modern nursing requires fluency with a surprising range of equipment. On the direct care side, nurses operate IV pumps, feeding pumps, ventilators, suction equipment, oxygen delivery systems, urinary catheters, chest tubes, wound drainage systems, and barcode medication administration scanners that help prevent dosing errors. For monitoring, they use telemetry systems that track heart rhythms, bedside monitors displaying real-time vitals, and pulse oximeters that measure blood oxygen levels.
Beyond bedside equipment, nurses work extensively with electronic medical records, electronic ordering systems, and communication devices that keep them connected to physicians, pharmacists, and other team members throughout a shift. They also manage patient safety devices like fall alarms, specialized pressure-relieving mattresses, and limb compression devices that prevent blood clots.
Three Levels of Nursing Practice
Not all nurses have the same scope of practice. The profession has three main tiers, each with different education requirements and clinical authority.
- Licensed Practical Nurses (LPNs) provide basic patient care: monitoring health status, updating records, and administering treatments under the supervision of registered nurses or physicians. They’re often the first point of contact for routine patient needs.
- Registered Nurses (RNs) have broader authority. They assess patients holistically, considering physical, psychological, and even spiritual needs. RNs coordinate across care teams, educate patients and families, perform diagnostics, and make independent clinical judgments about care plans.
- Advanced Practice Registered Nurses (APRNs) hold master’s or doctoral degrees and include nurse practitioners, nurse anesthetists, clinical nurse specialists, and certified nurse midwives. Nurse practitioners can prescribe medications, including antibiotics and controlled substances, in all 50 states. In nearly half the states, they have full practice authority and can run their own clinics, functioning much like primary care physicians.
Where Nurses Work
Hospitals are the most visible workplace, but nurses practice in dozens of other settings. School nurses manage chronic conditions like asthma and diabetes in students, handle first aid, administer medications, and track immunization compliance. Home health nurses visit patients recovering from surgery or injuries who need skilled care after discharge. Hospice nurses provide medical attention and comfort care for terminally ill patients, often in the patient’s own home.
Some nurses never touch a patient at all. Insurance claim nurses review medical claims for accuracy, using their clinical knowledge to determine whether billed treatments are appropriate and covered. Legal nurse consultants evaluate healthcare claims, conduct medical research, and serve as bridges between the nursing and legal fields. Others work in informatics, building and maintaining the electronic systems that hospitals depend on, or in public health, where they work with entire populations rather than individual patients.
Why Nurse Staffing Levels Matter
The quality of nursing care has a direct, measurable effect on whether patients survive a hospital stay. The most methodologically rigorous study to date on the topic, reviewed by the Agency for Healthcare Research and Quality, found a statistically significant relationship between higher registered nurse staffing levels and lower patient mortality. High patient turnover, where nurses are responsible for too many admissions and discharges in a single shift, was independently associated with excess deaths. In short, having enough nurses isn’t just a staffing preference. It’s a patient safety issue.
Pay, Job Growth, and Continuing Education
The median annual wage for registered nurses was $93,600 as of May 2024, according to the Bureau of Labor Statistics. Employment is projected to grow 5 percent from 2024 to 2034, faster than the average for all occupations, driven largely by an aging population and increasing demand for healthcare services.
Nursing also requires ongoing learning well past graduation. Most states require continuing education for license renewal. In New Jersey, for example, nurses must complete at least 30 contact hours of continuing education every two years, including at least one hour specifically focused on opioid prescribing risks and alternatives. Each contact hour equals 60 minutes of instruction, and up to 15 extra hours can carry over into the next renewal cycle. The specifics vary by state, but the principle is universal: nurses are expected to keep their knowledge current throughout their careers.
