An ED nurse is a registered nurse who works in a hospital’s emergency department, providing immediate care to patients with urgent and life-threatening conditions. Sometimes called an ER nurse, this role covers everything from assessing a patient’s severity within minutes of arrival to performing CPR, managing trauma injuries, and coordinating with doctors and specialists around the clock. It is one of the most fast-paced specialties in nursing, with a single nurse potentially seeing up to 10 patients in a shift.
What an ED Nurse Does on a Typical Shift
The core of emergency nursing is handling whatever comes through the door, without advance notice. On any given shift, an ED nurse might manage patients in shock, treat heart attacks and strokes, care for burn victims, dress wounds, assist with suturing, perform CPR, and monitor oxygen levels and breathing. The conditions they see most often include injuries and poisonings (about 20% of all ED visits), respiratory problems, abdominal pain, and chest pain.
Beyond direct patient care, ED nurses play a significant forensic role that many people don’t expect. More than half of emergency nurses regularly document evidence related to criminal cases, such as assaults or suspected abuse, while simultaneously treating the patient. They also coordinate across departments, communicating a patient’s status to surgeons, radiologists, and intensive care teams to keep treatment moving quickly.
During mass casualty events or natural disasters, ED nurses may be deployed to provide care at the disaster site itself or manage a surge of victims arriving at the hospital. This disaster response function is considered one of their eight core professional competencies.
Triage: The First Five Minutes
One of the most critical tasks an ED nurse performs is triage, the rapid assessment that determines how urgently each patient needs care. Using a five-level system called the Emergency Severity Index, the nurse evaluates every person who walks in or arrives by ambulance. The goal is to determine severity within five minutes.
The system works like this:
- Level 1: The patient needs immediate life-saving intervention. They may be unresponsive, not breathing, pulseless, or have oxygen levels below 90%. A doctor must be involved right away.
- Level 2: A high-risk situation where vital signs are abnormal (elevated heart rate, low oxygen, rapid breathing) and the patient needs multiple hospital resources, but isn’t in immediate cardiac or respiratory arrest.
- Level 3: The patient is stable but will likely need two or more resources, such as lab work, imaging, or IV medications.
- Level 4: The patient needs one resource, like an X-ray or a single lab test.
- Level 5: No hospital resources are needed beyond a basic exam. Think prescription refills or minor wound care.
The triage nurse checks pulse, breathing, airway, mental status, and bleeding to make this call. It’s a high-stakes decision that shapes the order in which every patient in the department gets treated.
How ED Nursing Differs From Other Units
The emergency department is fundamentally different from other hospital floors. Visits are unplanned, conditions are unknown until the patient arrives, and the nurse must be ready for anything from a sprained ankle to a gunshot wound. An ED nurse might care for 10 patients in a single shift, each with a completely different problem. By contrast, an ICU nurse typically focuses on just two patients over multiple shifts, providing deep, sustained monitoring for a single condition.
The recommended staffing ratio for a moderate-acuity emergency department is one nurse for every three patients, with no more than 1.25 new patients arriving per nurse per hour. Higher-volume departments also need dedicated triage and charge nurses on top of that baseline. In practice, the pace can feel relentless. ED nursing rewards people who think quickly under pressure, can pivot between tasks without warning, and stay calm when situations escalate.
Shifts and Scheduling
Most ED nurses work 12-hour shifts, which is the standard across acute care hospital settings. About 65% of hospital nurses report their most recent shift lasted 12 to 13 hours, and the median shift length is 12 hours regardless of state. Some facilities still offer 8-hour shifts, which about a quarter of nurses work, and a small number of hospitals have introduced flexible scheduling options with shorter shifts to help retain experienced nurses.
Because the emergency department never closes, ED nurses rotate through day, night, weekend, and holiday shifts. This around-the-clock schedule is one of the trade-offs of the role.
Education and How to Become an ED Nurse
To work as an ED nurse, you first need to become a registered nurse. That requires completing either an associate degree in nursing (two to three years, often at a community college) or a bachelor of science in nursing (four years at a university). People who already hold a bachelor’s degree in another field can enter an accelerated master’s-level nursing program that takes one to two years. After graduating, you must pass the national licensing exam known as the NCLEX.
There is no separate license specifically for emergency nursing. Once licensed as an RN, you can apply to work in an emergency department. However, most new ED nurses receive extensive on-the-job orientation, and many pursue additional certifications once they gain experience.
Specialty Certifications
The most recognized credential is the Certified Emergency Nurse (CEN) designation, awarded by the Board of Certification for Emergency Nursing. To sit for the CEN exam, you need an active, unrestricted RN license. Two years of emergency nursing experience is recommended but not required. Earning the CEN signals to employers and patients that a nurse has validated expertise in the specialty.
Many ED nurses also complete training in advanced cardiac life support and trauma nursing through additional certification courses. These credentials build competence in specific high-stakes scenarios like cardiac arrest and major traumatic injuries.
Salary and Job Growth
The median annual pay for registered nurses in the U.S. was $93,600 in 2024, with nurses working in hospitals earning a median of $97,260. ED nurses generally fall within this hospital range, though exact pay varies by location, experience, and shift differentials for nights and weekends.
Employment for registered nurses is projected to grow 5% from 2024 to 2034, which is faster than average across all occupations. Emergency departments, in particular, see consistent demand because of their 24/7 staffing needs and the steady volume of patients. The highest ED visit rates come from adults 65 and older, people in lower-income communities, and those in rural areas, populations that are growing or persistently underserved.
