What Does an ER Nurse Do?

An ER nurse provides immediate nursing care to people who arrive at a hospital emergency department with sudden illness or injury. The nurse quickly assesses each patient and helps identify who needs urgent attention, while monitoring for changes in condition. During treatment, the nurse carries out care and reports important observations to the clinical team. The nurse also helps coordinate transitions to hospital care or home. This work helps the emergency department direct care according to patients’ needs and maintain continuity as responsibility shifts.

What Is a ER Nurse?

An ER nurse is a registered nurse who cares for patients in a hospital emergency department. Patients may arrive with problems ranging from minor injuries to life-threatening illness, and the nurse’s immediate focus is to assess their condition and help ensure urgent needs are addressed. The nurse works alongside physicians and other clinical staff, sharing observations that support decisions about treatment and next steps.

Emergency care is not always predictable. A patient’s condition can worsen while waiting or during treatment, so the nurse reassesses patients and alerts the team when a change needs prompt attention. The work also includes documenting care and helping patients understand what happens when they leave the department or move to another unit.

What Are the Main Responsibilities of a ER Nurse?

Assessing patients and supporting triage. The nurse checks for immediate threats and gathers information about symptoms and relevant health history. Vital signs and the patient’s appearance help inform the initial assessment. Triage assigns a level of urgency to help direct care; it is not a diagnosis or a guarantee of how long a patient will wait. If a waiting patient’s symptoms or observations worsen, the nurse reassesses and communicates the change to the clinical team.

Providing and monitoring care. As the care plan proceeds, the nurse performs nursing interventions and observes how the patient responds. Depending on the plan and the nurse’s role, this may include starting an intravenous line when ordered or preparing a patient for imaging. The nurse reports significant changes so the team can consider whether the plan needs to change.

Supporting procedures and emergencies. The nurse prepares for procedures and carries out assigned tasks during them. In a resuscitation, clear role assignments and timely updates help the team coordinate care. The nurse documents key events and times so colleagues can follow what occurred.

Communicating and coordinating transitions. The nurse shares relevant observations with clinicians and records assessments and interventions. When patients are discharged, the nurse helps explain care instructions and when to seek further help. When patients move to another care setting, a clear handoff helps the receiving team understand their condition and care to date.

What Does a ER Nurse Do on a Daily Basis?

A shift commonly begins with a handoff from the departing team. The nurse reviews the patients’ current conditions and care plans, then takes responsibility for monitoring them. When a new patient arrives, the nurse makes an initial assessment and helps determine the urgency of the patient’s needs. The sequence varies with the department’s arrivals and patient acuity, so planned tasks may be interrupted when someone needs urgent attention.

As treatment gets underway, the nurse carries out assigned care and checks whether the patient’s condition is changing. The nurse updates the clinical team when observations raise concern and documents care as it happens. A patient who is waiting may need another assessment if symptoms change. Before the end of the shift, the nurse gives the incoming team a handoff about ongoing concerns and next steps.

Emergency departments operate around the clock, so shifts may include nights, weekends, or holidays. Work can involve extended periods standing and moving, as well as emotionally difficult situations. OSHA describes emergency-department workplace-violence risks, including overcrowding and long waits, and outlines prevention practices for healthcare facilities in its emergency-department guidance.

What Skills Does a ER Nurse Need?

Observation and clinical judgment help the nurse notice meaningful changes. For example, a new breathing difficulty or increasing confusion may matter even if an earlier measurement was not alarming. The nurse must recognize when observations warrant reassessment or prompt communication.

Clear communication supports coordinated care. The nurse needs to give clinicians concise updates about changes and document events clearly for colleagues. Patients and families may be frightened or in pain, so the nurse also needs to explain questions and next steps in a way they can understand.

Adaptability and composure matter when priorities shift. A nurse may need to pause routine work to respond to a patient whose condition has deteriorated, then return to other responsibilities without losing track of them. Teamwork helps keep care coordinated during procedures and emergencies.

How Much Does a ER Nurse Earn?

The U.S. Bureau of Labor Statistics reports a median annual wage of $97,550 for registered nurses in May 2025. This figure covers registered nurses across specialties and work settings; it is not a separate estimate for ER nurses. Actual pay can vary by location, employer, experience, and shift.

What Is the Career Progression for a ER Nurse?

ER nurses first need to qualify and obtain a license as registered nurses. The BLS describes nursing diplomas and associate’s or bachelor’s degrees as common educational routes and notes that registered nurses must be licensed. See the BLS registered nurse profile for these general pathways. Specific employer requirements for emergency-department positions can vary.

After gaining experience, an ER nurse may take on responsibilities such as supporting department education or coordinating a shift. Some nurses pursue leadership roles in emergency services. Advanced-practice nursing is another possible path, but it involves further education and licensure and is distinct from the registered nurse role. Career options depend on the nurse’s goals and the qualifications required for the position.

How Contingent Workforce Management Helps Businesses Hire ER Nurses

Contingent workforce management services help organizations engage temporary workers and manage the administrative parts of those assignments. In an emergency department, a temporary coverage gap can leave the team short while patients still need timely assessment and continuous monitoring. If the hospital has already identified an ER nurse, hiring that worker directly and using third-party payrolling can be a lower-cost alternative to a staffing agency. The facility must still confirm qualifications and complete its credentialing and orientation before the nurse begins patient care.

TCWGlobal helps companies manage contingent ER nurses through payrolling and workforce support for the assignment. When a hospital has selected the nurse, these services can handle employment administration and pay processes while the facility manages clinical credentialing and onboarding. Using the selected worker rather than a staffing agency can save the company money, and shifting assignment administration to a workforce provider can reduce internal administrative work.
