Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

This registry role asks for 48 hours a month, two weekend shifts and a summer and winter holiday. How do you plan your month so you meet that commitment without it slipping?

What they are checking: Whether they will reliably cover the hard shifts the registry exists to fill, not just the convenient ones.

Tell me about a time you noticed a patient getting worse before anyone else did. What tipped you off and what did you do?

What they are checking: Whether their assessments catch subtle change early and whether they act on it instead of waiting.

Describe a time you had to escalate a concern up the chain of command. How did you decide it was time?

What they are checking: Whether they know when bedside effort is not enough and are willing to go over someone's head for safety.

What do you bring to a team you only work with a few times a month, and how do you build trust with them?

What they are checking: Whether a registry nurse fits in quickly and pulls their weight rather than staying on the edges of the team.

How do you stay current on ED skills and policies when you work fewer hours than full-time staff?

What they are checking: Whether they take personal ownership of competency instead of relying on full-time hours to keep them sharp.

What would you do

You pick up a shift in the Lake Geneva emergency department after not working there for two weeks. What do you do in your first fifteen minutes to get oriented?

What they are checking: How a part-time nurse closes the gap on protocol changes, supplies and staffing before taking patients.

You are about to give a medication and the dose looks high for the patient's weight. The physician is busy with a trauma. What do you do?

What they are checking: Whether they hold a questionable order and verify it even when the prescriber is hard to reach.

A family member is yelling at the front desk because their mother has waited three hours. How do you handle it?

What they are checking: Whether they can de-escalate calmly, give honest information, and keep the waiting patient safe.

About the work

Walk me through how you triage three patients who arrive at once: chest pain, a child with a high fever, and an adult with a deep laceration.

What they are checking: Whether their priorities follow acuity and threat to life rather than who arrived first or looks most upset.

A patient comes in with sudden slurred speech and one-sided weakness. What do you do and in what order?

What they are checking: Whether they know stroke time windows, last known well, and how fast the team needs to be activated.

How do you keep your ED documentation complete and timely when the board is full and you have no downtime?

What they are checking: Whether they chart close to real time, since late charting in the ED creates safety and legal gaps.
