Behavioral Health Nurse interview questions and how to answer them

A behavioral health nurse interview is mostly scenarios. Managers want to hear how you'd handle a patient who's pacing and shouting, a patient who says they're fine but won't meet your eyes, and a patient whose shakes turn into a seizure. Clinical knowledge matters, but the thing they're really checking is whether you stay calm and keep everyone safe.

12 questions7 minute read

Part 1

1.A patient is pacing, yelling at staff and getting closer to another patient. Walk me through what you do.

Why they ask

Agitation is a daily event on most behavioral units. They want to hear a sequence that starts with words and space, not with hands or a syringe.

How to answer

  • Call for backup and move other patients out of the area first
  • Approach at an angle, keep distance and an exit, and lower your voice
  • Name what you see, offer a choice, like a quiet room or an as-needed medication
  • Escalate to restraint or emergency medication only as a last resort and per policy
  • Debrief with staff and the patient afterward and document clearly

2.How do you assess suicide risk on admission?

Why they ask

Every behavioral setting screens for suicide, and a missed risk is the outcome they fear most. They want a structured tool plus clinical judgment.

How to answer

  • Name a structured tool you've used, such as the Columbia Suicide Severity Rating Scale
  • Ask directly about thoughts, plan, intent, means and past attempts
  • Look at protective factors and what the patient says would keep them safe
  • Escalate to the provider and put the right observation level in place right away

3.A patient in alcohol withdrawal starts scoring higher every time you check. What do you do?

Why they ask

Detox and crisis units see medical emergencies dressed up as behavioral ones. They want to know you won't miss a seizure or delirium tremens.

How to answer

  • Describe using CIWA scoring and medicating per protocol
  • Recheck vitals, look for confusion, hallucinations and tremor
  • Call the provider early if scores keep rising despite medication
  • Know when the patient needs a higher level of care, like a medical floor
4.A patient refuses their scheduled antipsychotic. How do you handle it?

Why they ask

Refusals are routine, and the rules about involuntary medication vary by state and by the patient's legal status. They want respect for autonomy plus good follow-through.

How to answer

  • Ask why, since side effects like stiffness or weight gain are common reasons
  • Offer information and try again later rather than arguing
  • Document the refusal and the reason, and tell the provider
  • Follow your facility's policy on involuntary medication, which depends on state law and court orders
5.A patient says their chest hurts, and a coworker says they always complain for attention. What do you do?

Why they ask

People with mental illness have their physical symptoms dismissed all the time. They want someone who assesses every complaint as real.

How to answer

  • Do a full assessment, vitals and an ECG if your unit has one
  • Check medications that raise cardiac risk and any history
  • Escalate to the provider with an SBAR, regardless of the patient's history
  • Mention that you'd raise the dismissive comment with the coworker kindly

Part 2

6.A patient asks for your personal phone number or wants to follow you on social media. How do you respond?

Why they ask

Boundary problems cause real harm in this specialty. They want a warm but firm answer.

How to answer

  • Decline clearly without shaming the patient
  • Redirect to what you can offer during the shift
  • Tell the team so everyone holds the same line
  • Document it if your facility expects that
7.Tell me about a time you worked with a patient who had both a mental illness and a substance use disorder.

Why they ask

Co-occurring disorders are the norm in behavioral health, not the exception. They want to see you treat both at once.

How to answer

  • Pick a real patient, with details kept private
  • Explain how withdrawal or intoxication changed what you saw psychiatrically
  • Describe working with the provider and counselor on a shared plan
  • Say what happened and what you'd do differently
8.Have you been involved in restraint or seclusion? Walk us through it.

Why they ask

Restraint is high-risk and heavily regulated. They want to know you understand monitoring, documentation and the goal of ending it quickly.

How to answer

  • Describe what led up to it and what was tried first
  • Explain your role and how you watched airway, circulation and skin
  • Mention documentation and the provider order timing your facility required
  • Describe the debrief and how the team tried to prevent the next one
9.What would you do if a patient told you they planned to hurt a specific person after discharge?

Why they ask

This touches confidentiality and duty to warn, which vary by state. They want escalation, not you acting alone.

How to answer

  • Stay calm and get specifics about the plan
  • Tell the provider and your charge nurse right away
  • Follow facility policy, which reflects your state's duty-to-warn rules
  • Document the patient's exact words
10.How do you work with therapists, social workers and techs on the unit?

Why they ask

Behavioral care runs on a team, and nurses who act as the only clinicians cause friction.

How to answer

  • Give an example of a treatment team meeting where you shared something useful
  • Mention how you use techs' observations from rounds
  • Describe handling a disagreement respectfully

Part 3

11.Why behavioral health, and why this setting?

Why they ask

Turnover is high, and they want someone who picked this on purpose.

How to answer

  • A real moment that drew you in, like a patient on a medical floor
  • Why this setting, such as detox, crisis or outpatient, fits you
  • What you want to learn next, such as certification
12.How do you look after yourself after a hard shift?

Why they ask

Burnout and secondhand trauma are common. They want someone with a plan, not a martyr.

How to answer

  • Name concrete habits that actually help you
  • Mention using debriefs or an employee assistance program
  • Show you know when to ask for help

Questions to ask them

Ask at least two. It shows you're picking them too.

  • What does the unit do after a restraint or a violent incident, and who leads the debrief?
  • How many techs and nurses are on at night, and who responds to a behavioral code?
  • What de-escalation training do you provide, and how often is it refreshed?
  • How do you handle patients who get medically sick, and how fast can they transfer?
  • What does orientation look like for a nurse coming from a medical floor?
