Nurses are the frontline of patient care. They perform physical exams, administer medications, monitor vital signs, coordinate treatment plans, and serve as the primary point of contact between patients and doctors. While the specific tasks vary by setting and specialty, the core of nursing is hands-on clinical care combined with patient education and advocacy.
Day-to-Day Responsibilities
A registered nurse’s daily work centers on assessing patients and responding to what they find. That includes conducting physical exams, reviewing symptoms and medical history, recording health observations, administering medications and treatments, and using medical equipment to track a patient’s condition. Nurses also coordinate care across a patient’s entire team of providers, making sure everyone from the specialist to the physical therapist is on the same page.
Beyond the clinical tasks, nurses spend a significant amount of time teaching. They explain diagnoses to patients and families, walk through treatment plans, and describe what at-home care looks like after discharge. If a family member needs to understand a loved one’s condition or learn how to manage wound care at home, it’s typically the nurse who has that conversation.
Where Nurses Work
Hospitals are the most familiar setting, but nurses work in dozens of environments. Outpatient clinics, home health agencies, schools, correctional facilities, insurance companies, and public health departments all employ nurses. A school nurse handles allergic reactions, promotes student wellness, and responds to emergencies on campus. A nurse in a correctional facility focuses largely on managing chronic conditions among inmates while also responding to medical emergencies for both prisoners and staff.
The setting shapes the work. A nurse in a primary care clinic might spend most of the day triaging phone calls and assisting with routine checkups. A home health nurse drives between patients’ houses, managing wound care, medication schedules, and post-surgical recovery independently. The variety is one reason nursing attracts people with very different personalities and interests.
How Specialties Change the Job
Nursing specialties create dramatically different work experiences. Two of the most intense are emergency nursing and intensive care nursing, and comparing them illustrates just how much the role can shift.
Emergency room nurses treat patients with acute, unplanned conditions: severe injuries, heart attacks, strokes. Their work is fast-paced and procedural. They triage incoming patients by urgency, stabilize them, start IVs, give stitches, set broken bones, and perform airway procedures like intubations. An ER nurse might see up to 10 patients in a single shift, each with a different problem.
ICU nurses, by contrast, go deep rather than wide. Their patients have life-threatening conditions and are often on ventilators and multiple medications simultaneously. An ICU nurse may care for just 2 patients over multiple shifts, monitoring every change in condition, adjusting treatments, and delivering ongoing updates to doctors and families. The pace is slower but the stakes on each decision are extremely high.
Other specialties include neonatal nursing (caring for premature or critically ill newborns), psychiatric nursing, surgical nursing, oncology, cardiology, and pediatrics. Each requires additional training and carries its own rhythm.
LPN, RN, and Nurse Practitioner: What’s Different
Nursing has a clear professional hierarchy, and each level comes with different authority and responsibilities.
- Licensed Practical Nurses (LPNs) work under the supervision of a registered nurse or physician. They collect patient data and assist with care, but they cannot independently assess patients, formulate nursing diagnoses, or interpret clinical data on their own. If a patient becomes unstable, the RN takes over primary care.
- Registered Nurses (RNs) function independently. They perform comprehensive assessments, create nursing diagnoses, develop care plans, and direct the work of LPNs. The RN decides how much supervision an LPN needs based on the complexity of the task and the stability of the patient.
- Nurse Practitioners (NPs) hold graduate degrees and can provide primary and specialty healthcare, often with prescribing authority. They coordinate patient care at a level closer to a physician’s scope, with a median salary of about $132,050.
Education and How to Become a Nurse
There are two main paths to becoming a registered nurse. An Associate Degree in Nursing (ADN) is a two-year program, typically offered at community colleges, with tuition ranging from $6,000 to $20,000. Some accelerated programs finish in 18 months. A Bachelor of Science in Nursing (BSN) is a four-year university program costing anywhere from $40,000 to over $200,000 depending on the school.
Both degrees qualify you to take the licensing exam and work as an RN, but the job market increasingly favors the BSN. Many healthcare facilities only consider candidates with a bachelor’s degree during hiring. A BSN is also required if you ever want to pursue a graduate nursing program to become a nurse practitioner, nurse anesthetist, or nurse midwife.
Salary and Job Outlook
The median annual wage for registered nurses was $93,600 as of May 2024. The lowest 10 percent earned under $66,030, while the highest 10 percent earned more than $135,320. Holding a BSN pushes earnings higher: staff RNs with a bachelor’s degree earn roughly $107,960 per year on average.
Specialization and advanced degrees can push salaries much further. Certified Registered Nurse Anesthetists are the highest-paid nurses in 2025, earning an average of $223,210 per year. Psychiatric mental health nurse practitioners average about $151,600, and pediatric nurse practitioners around $135,160. Even roles that don’t require a graduate degree pay well at the specialty level: ICU nurses average roughly $118,700 and neonatal nurses about $127,400.
Demand for nurses remains strong. The aging population, expansion of chronic disease management, and ongoing staffing shortages across healthcare systems mean nursing consistently ranks among the most secure career paths in the country.
