The short answer: ER nurse interviews focus on prioritization under pressure: how you triage, how you handle several critical patients at once, how you act in a code or rapid deterioration, and how you work with a fast-moving team. Expect scenario questions (“You have three patients arriving at once…”), behavioral questions about difficult patients and families, and questions about how you cope with stress. Answer clinical scenarios with a clear method, such as ABCs and your triage system, and behavioral questions with real stories. Below are the common questions with sample answers and what managers listen for.
Sample answers are illustrations, not quotes from real candidates. Use your own experience.
Triage and prioritization
“How do you prioritize multiple patients?”
What they listen for: a clear, safe method.
Sample answer: “I start with airway, breathing and circulation, then look at who’s most likely to deteriorate. In our department we triage with the Emergency Severity Index, which sorts patients into five levels by acuity and the resources they’ll need. On a busy shift I keep reassessing, because a stable patient in the waiting room can change quickly, and I escalate early rather than waiting.”
The Emergency Severity Index (ESI) is a five-level triage system that the Emergency Nurses Association acquired in 2019 and describes as used by nearly every emergency nurse in the United States. If you’ve used a different triage system, say which and how.
“Three patients arrive at once: chest pain, a child with a high fever, and an ankle injury. Who do you see first?”
How to answer: Walk through your reasoning, not just the answer: the chest pain patient first for a rapid assessment and ECG per protocol, because of the risk of a heart attack; the child next, checking for signs of sepsis or respiratory distress; the ankle injury last if stable, with pain management and reassessment. Mention delegating and escalating.
Clinical scenarios
“A patient suddenly deteriorates. What do you do?”
Assess ABCs, call for help or the rapid response team, start appropriate interventions within your scope, communicate clearly using SBAR, and document. Give a real example if you have one.
“Describe your role in a code.”
Explain roles you’ve held (compressions, airway support, medications, recorder), how you follow ACLS or PALS algorithms, and how you communicate in closed loops. Mention your certifications.
“How do you handle a patient who is aggressive?”
Stay calm, keep a safe distance and an exit, use de-escalation (a calm voice, acknowledging their feelings), involve security early if needed, and follow your hospital’s policy. Consider medical causes such as hypoxia, hypoglycemia or intoxication.
Patients and families
“Tell me about a time you dealt with a difficult family member.”
Sample answer: “A father was shouting at the desk because his son had been waiting four hours with a broken arm. I took him aside, acknowledged how long they’d waited, explained that patients are seen by urgency, not arrival time, and gave him a realistic update. I made sure his son had pain relief and checked in every 30 minutes. He apologized later and thanked us.” See our guide to difficult customer questions.
“How do you support a family after a patient dies?”
Show compassion and honesty: a private space, clear and simple language, time for questions, involving chaplaincy or social work, and taking care of yourself afterward.
Teamwork and pressure
- “Tell me about a time you disagreed with a physician’s order.” Show you raised it respectfully, with your reasoning, and followed the chain of command when needed.
- “How do you handle a shift when you’re short-staffed?” Prioritize, communicate with the charge nurse, delegate safely, and escalate unsafe staffing.
- “Tell me about a mistake you made.” Be honest about a near miss or error, what you did immediately, and what you changed. See tell me about a time you failed.
Stress and self-care
“How do you cope with the stress of emergency nursing?”
Be honest and specific: debriefing with colleagues after hard cases, using employee support programs, exercise, sleep and time off. See our guide to how do you handle stress.
“Why emergency nursing?”
Connect to something real: you thrive on variety and pace, you like making a difference in the first critical hours, or a specific experience drew you in.
Questions to ask the nurse manager
- What’s the nurse-to-patient ratio, and how are surges handled?
- What does orientation look like for new ER nurses?
- Which triage system do you use, and when do nurses start triaging?
- How does the team debrief after difficult cases?
The job market
The U.S. Bureau of Labor Statistics reports a median annual wage of $97,550 for registered nurses in May 2025, with employment projected to grow 6% from 2025 to 2035 and about 180,800 openings a year.
