What Do Nurses Do?

Nurses are the largest group of healthcare professionals in the United States, and they do far more than take temperatures and hand out medication. They assess patients, administer treatments, coordinate care, educate families, and often act as the first line of defense in spotting a change in a patient’s condition. Nursing is a practice built on clinical judgment, not just task completion. It requires a deep understanding of the human body, sharp observation skills, and the ability to make rapid decisions when a patient’s status changes.

What Do Nurses Do on a Typical Shift?

A nurse’s day depends heavily on the setting. A nurse in an intensive care unit works differently from a school nurse or a home health nurse. But the core responsibilities remain consistent.

During a hospital shift, a nurse begins by reviewing each patient’s chart, lab results, and notes from the previous shift. They then conduct a physical assessment of every patient. This is not a quick glance. It involves listening to the heart and lungs, checking the skin, evaluating mental status, and reviewing vital signs. This baseline assessment is how a nurse detects subtle changes that may signal a problem hours before it becomes obvious.

Medication administration is a major part of the job. Nurses verify the right drug, the right dose, the right patient, the right route, and the right time. They also monitor for side effects and allergic reactions. Beyond medications, nurses manage IV lines, change dressings, insert catheters, and operate monitoring equipment.

Documentation takes a surprising amount of time. Every assessment, medication, and procedure must be recorded in the electronic health record. This is not busywork. It ensures continuity between shifts and protects patients from errors.

How Do Nurses Assess Patients?

Assessment is the foundation of nursing practice. It is a systematic process of gathering information about a patient’s physical, psychological, and social condition. A nurse uses their senses, clinical tools, and conversation to build a complete picture of the patient’s health.

The physical exam follows a head-to-toe approach. The nurse checks the airway, breathing, and circulation first, then moves through the body system by system. They listen to bowel sounds, check for swelling in the extremities, assess pupil response, and evaluate muscle strength. These findings are compared to the patient’s baseline and to known normal ranges.

Assessment also includes taking a health history. The nurse asks about current symptoms, past surgeries, chronic conditions, and medications. They ask about lifestyle factors like smoking, alcohol use, and diet. This information helps the care team understand the whole person, not just the presenting complaint.

Assessment is continuous. A nurse does not assess once at the start of a shift. They reassess after procedures, after medications, and whenever a patient reports a change in how they feel. This ongoing vigilance is what catches complications early.

What Procedures and Treatments Do Nurses Perform?

Nurses perform a wide range of clinical procedures. The exact list depends on state regulations and facility policy, but many tasks are standard across the country.

Common procedures include starting and managing intravenous lines, drawing blood, inserting urinary catheters, and placing nasogastric tubes. Nurses also perform wound care, which involves cleaning, debriding, and dressing surgical incisions or pressure injuries. They administer oxygen, manage ventilators, and monitor cardiac rhythms.

Medication administration goes far beyond giving pills. Nurses give IV pushes, run continuous infusions, administer injections, and manage patient-controlled analgesia pumps. They calculate doses based on weight and kidney function. They hold medications when a patient’s condition contradicts the drug’s use.

Nurses also perform point-of-care testing. They run glucose checks, urine tests, and blood gas analyses. In many emergency settings, nurses are trained to interpret these results immediately and act on them before the physician arrives.

How Do Nurses Coordinate Care and Communicate?

Nurses are the hub of the healthcare team. They are the ones at the bedside around the clock. When a physician rounds in the morning, the nurse provides the update: what changed overnight, what the vital signs are trending toward, and what concerns the patient has voiced.

This coordination extends beyond doctors. Nurses communicate with pharmacists about drug interactions, with physical therapists about mobility status, with dietitians about nutritional needs, and with social workers about discharge planning. They relay critical lab results and radiology findings to the appropriate providers.

Nursing shift reports are a structured handoff of information. The nurse leaving gives the nurse arriving a complete picture of each patient’s status, pending tests, and care plan. Miscommunication at this point is a leading cause of medical errors, so many facilities now use standardized handoff tools to structure the exchange.

Nurses also serve as patient advocates. When a patient cannot speak for themselves, the nurse speaks for them. This might mean questioning an order that seems wrong, requesting additional pain control, or ensuring a patient’s wishes are respected in end-of-life discussions.

How Do Nurses Educate Patients and Families?

Patient education is a formal part of nursing practice, not an afterthought. Before a patient is discharged from the hospital, the nurse must confirm they understand their diagnosis, their medications, and their follow-up plan.

This teaching covers practical skills. A nurse may teach a patient how to inject insulin, how to care for a surgical wound, or how to recognize the signs of an infection. They teach family members how to operate a home oxygen machine or how to position a bedridden relative to prevent bedsores.

Education is tailored to the patient’s level of health literacy. A nurse does not hand someone a pamphlet and walk away. They explain, demonstrate, and then ask the patient to explain it back. This teach-back method confirms understanding and reduces the risk of readmission.

Nurses also provide emotional support. They help patients process a new diagnosis, cope with chronic illness, and make decisions about treatment options. This aspect of care is often invisible in medical records, but it is a core reason patients report high satisfaction with their nurses.

What Is the Difference Between an RN and an LPN?

The two most common nursing titles are Registered Nurse (RN) and Licensed Practical Nurse (LPN), sometimes called Licensed Vocational Nurse (LVN) in some states. The difference is in education, scope of practice, and responsibility.

An RN completes either a two-year associate degree or a four-year bachelor’s degree, followed by passing the NCLEX-RN exam. RNs perform comprehensive assessments, create care plans, administer complex medications, and make independent clinical judgments.

An LPN typically completes a one-year diploma program and passes the NCLEX-PN exam. LPNs provide basic nursing care: taking vital signs, changing dressings, administering certain medications, and assisting with daily activities. They work under the supervision of an RN or physician.

Advanced practice registered nurses (APRNs) go further. Nurse practitioners, nurse midwives, nurse anesthetists, and clinical nurse specialists hold master’s or doctoral degrees. They can diagnose conditions, prescribe medications, and in many states, practice independently without physician oversight.

Where Do Nurses Work Besides Hospitals?

Hospitals employ the largest share of nurses, but they are far from the only setting. Clinics, schools, and workplaces all rely on nurses.

Outpatient clinics employ nurses for primary care, specialty care, and urgent care. These nurses handle patient intake, administer vaccines, assist with minor procedures, and manage chronic disease education.

Home health nurses visit patients in their homes. They care for people recovering from surgery, managing chronic conditions, or receiving end-of-life hospice care. This role requires significant independence, as there is no physician or colleague down the hall.

Public health nurses work for government agencies and community organizations. They run immunization clinics, conduct disease surveillance, and educate the public on health issues. School nurses manage everything from minor scrapes to life-threatening allergic reactions. Occupational health nurses in corporate settings handle workplace injuries and wellness programs.

Nurses also work in surgery, radiology, oncology, and mental health facilities. Some work in telehealth, providing advice and triage over the phone or video. The flexibility of the profession allows nurses to move between settings as their interests and life circumstances change.

What Skills Make a Good Nurse?

Clinical knowledge is essential, but it is not enough. Nursing requires a specific set of human skills that cannot be learned from a textbook.

Critical thinking is at the top of the list. A nurse must interpret data, recognize patterns, and act when something does not fit the expected picture. A slight change in a patient’s blood pressure or mental status can be the first sign of a serious complication.

Communication matters as much as technical skill. Nurses must explain complex medical information in plain language. They must listen actively to patients who may be frightened or confused. They must document precisely and speak clearly in urgent situations.

Physical stamina is a real requirement. Hospital nurses routinely work 12-hour shifts on their feet. They lift and reposition patients, move equipment, and respond to emergencies. The job is physically demanding in ways that surprise many new graduates.

Emotional resilience is equally important. Nurses witness suffering, loss, and difficult decisions daily. They must maintain compassion without becoming overwhelmed. This balance is one of the hardest parts of the job, and it is why burnout rates in nursing are a serious concern.
