ER nurse interviews test triage judgment, how you keep eight patients safe when four of them are waiting, how you handle violence and intoxication without losing compassion, and how you work in a department where the next hour is unknown. Expect triage scenarios, a question about a patient who deteriorated in the waiting room, and questions about de-escalation. The general questions are in nursing interview questions, the critical care version is ICU nurse interview questions, and the question behind most of the scenarios is how do you handle pressure. This page gives 10 questions with what a strong answer contains, 3 sample answers you can adapt, a table of the rounds to expect, and a practice plan for the week before.
What the interview looks like
| Round | What happens | Prepare |
|---|---|---|
| Phone screen | Licence, BLS/ACLS/PALS, TNCC or ENPC if held, ER experience and volume, trauma level, shifts | A summary of departments worked, annual volume and trauma designation |
| Manager and charge nurse interview | Triage scenarios, waiting-room deterioration, violence and de-escalation, sepsis and stroke pathways, behavioral questions | Scenario answers organised by acuity, with reassessment and escalation |
| Peer interview or shadow shift | Meet the team, see the flow, sometimes a short shadow | Questions about ratios, boarding, security presence and charge support |
ER nurse interview questions and what strong answers contain
- Three patients arrive at once: chest pain, a child with a fever, and an intoxicated man with a head wound. Who do you see first? Acuity-based triage with reasoning; ESI level thinking; what you delegate; reassessment of the others.
- Tell me about a patient who got worse in the waiting room. What was missed or not, how it was caught, what changed in the process.
- How do you de-escalate an aggressive patient or visitor? Calm voice, space, one speaker, offering choices, security early, personal safety first.
- Walk me through your sepsis or stroke recognition. Screening criteria, time-critical steps, team activation, documentation.
- How do you keep patients and families informed during long waits? Rounding, honest time estimates, reassessment, escalation when a wait becomes unsafe.
- Describe your experience with trauma. Level of centre, role in the bay, procedures assisted, what you want to learn.
- How do you handle a provider who dismisses your concern? Restate with data, use the chain of command, document; patient first.
- How do you manage boarding patients who are really inpatients? Inpatient-style care in the ER, medication timing, pressure injury and fall prevention, advocating for beds.
- Tell me about a mistake in the ER and what you learned. What happened, how it surfaced, the system fix.
- Why the ER? Honest reasons tied to the work, not the drama.
Sample answers
Three patients arrive at once. Who do you see first?
The chest pain goes to a bed and a monitor now, with an ECG within ten minutes, because that is a time-critical pathway. The intoxicated man with a head wound is second, because a head injury plus alcohol hides deterioration, so he gets a neuro check and a short reassessment interval rather than a chair in the corner. The febrile child gets a quick look to rule out the things that cannot wait, then a wait with a plan. I tell the charge nurse what I have and I reassess all three; triage is a process, not a single decision.
How do you de-escalate an aggressive patient or visitor?
Lower my voice and slow down, give them space and one person to talk to, and name what I can see: you have been waiting a long time and nobody has told you anything. I offer real choices, water, a quieter spot, an update in ten minutes, and I keep the exit behind me. Security is called early, before I need them, not as a punishment. If a patient is intoxicated or confused I treat it as a clinical problem, not a behaviour problem. My own safety and the other patients' come first, and I have left a room when that was the right thing to do.
Tell me about a patient who got worse in the waiting room.
A woman in her sixties was triaged with abdominal pain, stable, and over two hours her pain and heart rate crept up while the department was slammed. The tech doing reassessments flagged it and I pulled her in; it was a perforation and she went to theatre. What changed afterwards was our reassessment interval for abdominal pain over a certain age, and I now walk the waiting room myself once an hour whatever the board looks like, because the chart cannot see faces.
Mistakes to avoid
- Triage answers with no reasoning or no reassessment of the patients you did not pick.
- De-escalation described as being tough; managers want calm and early security.
- No trauma honesty; say your level and what you have and have not done.
- Choosing the ER 'for the adrenaline' in the why question.
A practice plan for the week before
- Rehearse three multi-patient triage scenarios aloud with your reasoning and the reassessment plan.
- Write your waiting-room deterioration story and the process change it led to.
- Review your department's sepsis and stroke pathways so the time-critical steps come out in order.
- Run a mock interview from the posting and answer the de-escalation and provider-disagreement questions aloud.
- Prepare questions about ratios, boarding, security, charge support and orientation.
