What Does a Registered Nurse Do?

Published on: October 4, 2022

Registered nurses are the professionals that patients typically see the most: the ones coordinating care, tracking how a patient is responding to treatment and making sure everyone on the medical team is aligned. It's a role that covers a wide range of daily work, depending on the setting, patient population and specialty a nurse chooses.  

This article covers what a registered nurse is, the skills the role demands, where RNs work and how the job can grow into something bigger. 

What Is a Registered Nurse? 

So, what is a registered nurse? An RN is a licensed nursing professional who has completed an approved nursing program (either an associate degree or a bachelor's degree in nursing) and passed the NCLEX-RN, the national licensing exam. Once licensed, an RN practices under a defined scope of practice set by their state board of nursing, which governs what an RN can assess, administer and perform independently versus under a provider's order. While that scope can vary by state, the core license and the exam behind it are consistent nationwide.  

The registered nurse occupational outlook from the Bureau of Labor Statistics is positive, with an above-average job growth rate of 5% anticipated between 2024 and 2034.    

What Does a Registered Nurse Do Day to Day? 

Ask ten RNs what their day looks like, and you'll get ten different answers. Although the specifics shift by setting and specialty, a few core duties show up across nearly every registered nursing role: 

• Assess patients and record medical histories and symptoms 
• Administer medications and treatments, then monitor for reactions 
• Develop, implement and evaluate patient care plans with the medical team 
• Perform wound care and other hands-on procedures 
• Operate medical equipment and run diagnostic tests 
• Chart care and maintain electronic medical records 
• Educate patients and families on managing an illness or injury 
• Supervise LPNs, nursing assistants and nursing students 

How Does an RN Coordinate Care Across a Team? 

An RN is the connective tissue of a care team. A patient might see a specialist for one problem, a physical therapist for another and a primary provider for everything in between, but none of those providers are in the room at the same time to compare notes. The RN is the one tracking how a patient is doing across those touchpoints and flagging when something isn't adding up. 

Because of this coordination, RNs are often the first to catch a problem before it becomes serious. Whether there’s a change in a patient's breathing, a medication that isn’t working properly or a symptom that doesn't match the chart, an RN is positioned to notice issues before any single specialist. This is also why RNs spend so much of a shift on communication rather than hands-on procedures alone, since keeping a care team aligned takes constant, active coordination.  

Skills Every Registered Nurse Needs 

The job asks for a specific set of abilities, and each one shows up in a real situation rather than as an abstract trait on a job posting. 

Clinical Judgment 

When a standard treatment isn't producing the expected result, an RN has to recognize that quickly, weigh the alternatives and determine the next step, often without time to consult a textbook. That judgment is built through training and repetition, not guesswork. 

Communication 

An RN translates medical information into language a patient or family member can actually use, then hands that same information off cleanly to the next shift so nothing gets lost. A shift change with a gap in communication is where mistakes tend to happen. 

Compassion and Emotional Resilience 

RNs care for people on some of the worst days of their lives. They may see multiple patients in a single shift, and they have to stay steady and present for each one. That takes genuine compassion, paired with the resilience to keep functioning well after an emotionally difficult moment. 

Attention to Detail 

Medication dosing, charting and ongoing monitoring leave little room for error. A missed decimal point or an overlooked change in vital signs can have real consequences, making strong attention to detail a baseline requirement of the job. 

Physical and Mental Stamina 

RNs spend long shifts on their feet, moving between patients and responding to whatever comes up next. The physical demands of the job are matched by the mental load of staying sharp for twelve hours at a stretch. 

Where Do Registered Nurses Work? 

RNs work in a variety of settings, including:  

• Hospitals 
• Outpatient clinics 
• Physicians' offices 
• Home health settings 
• Nursing care facilities  
• Schools  

Some take on travel nursing assignments that move them between locations every few months, often to fill short-term staffing gaps. Setting drives scheduling as much as it drives daily duties: a hospital RN might work rotating twelve-hour shifts around the clock, while an RN in a physician's office or a school setting typically works standard weekday hours. Home health RNs, by contrast, often manage their own schedule across a caseload of patients spread throughout a region.  

Nursing Specialties and How the Role Changes 

The same RN license can lead to very different day-to-day work depending on the specialty a nurse chooses. A pediatric RN spends the day managing young patients and anxious parents. An oncology RN builds long-term relationships with patients moving through treatment, often over months. A geriatric RN manages the layered health needs that come with aging, frequently alongside multiple chronic conditions. A critical care RN works in a high-acuity unit where a patient's condition can change by the minute. The license is the same across all four, but the pace, relationships and clinical demands are not. 

How Do Registered Nurses Advance Their Careers? 

RN licensure is often the starting point for a nursing career. Graduate education is how nurses expand their scope of practice or step into leadership roles beyond the bedside. An MSN is the most common path into advanced practice, preparing nurses for roles such as nurse practitioner, where responsibilities include assessing, diagnosing, developing treatment plans and prescribing medications.  

Other RNs use graduate education to move toward nursing administration, education or informatics rather than direct patient care. An MSN can lead in several different directions depending on the concentration a nurse chooses. For a nurse who has found the ceiling of the RN role but isn't ready to leave patient care behind, an online MSN is usually the next step. 

Advance Your Nursing Career With an Online MSN From Husson 

A registered nurse assesses, treats, educates and coordinates care, often while holding together the connections between every other provider a patient sees. It's a demanding role built on clinical judgment, communication and stamina, and it looks different depending on the setting and specialty a nurse chooses. For RNs who've reached the edge of what the license allows, graduate education is the way to keep growing. 

Husson University’s online MSN programs are built for working RNs who want to move into advanced practice or leadership without stepping away from their current job. If you're ready to take the next step in your nursing career, it's worth exploring what an online MSN could open up.
