## Question

A 38-year-old client comes to the emergency department voluntarily reporting intrusive violent thoughts about a specific co-worker, including a stated plan to confront the co-worker at the office tomorrow. The client states the thoughts are getting stronger but the client does not want to act on them. The client has access to a handgun at home. Which actions are essential? Select all that apply.

1

Place the client in a safe room with continuous observation by trained staff and remove all potential weapons or dangerous items

2

Document the client's statements using broad, non-specific language to safeguard privacy and minimize legal risk in the medical record.

3

Discharge the client home with a 24-hour mental health follow-up appointment because the client is voluntary and denies immediate intent to act.

4

Ask the client directly about access to the firearm and whether the firearm is currently accessible, and arrange means restriction with family or law enforcement

5

Notify the identified co-worker (the intended victim) per the duty-to-warn obligation under Tarasoff principles, with provider involvement

6

Reassure the client that information shared will be kept strictly confidential so the client feels safe disclosing further details.

## Explanation

Homicidal ideation with a specific identified target, a plan, and means (firearm access) is a psychiatric emergency requiring immediate safety, duty-to-warn, and means restriction. Required actions: (1) safe environment with continuous observation and removal of potential weapons (psychiatric ED safety bundle); (2) duty to warn the identified co-worker per Tarasoff v. Regents — most jurisdictions require notifying the identified victim and law enforcement when a serious threat to a specific person is disclosed; (3) explicit means restriction — ask about firearm access and arrange secure storage off-site, transfer to family, or law enforcement temporary surrender (the most evidence-based intervention to prevent homicide and suicide). Promising absolute confidentiality (option 6) is unethical when third-party harm is foreseeable. Vague documentation (option 2) endangers the third party and the team legal protection. Discharge home with a 24-hour outpatient follow-up (option 3) is grossly inadequate for active homicidal ideation with means and a specific target — typically requires inpatient psychiatric admission, often involuntary.

## In-depth explanation

Homicidal Ideation Crisis Triage
Specific target plus plan plus means plus escalating intent equals imminent risk. Three legal and clinical pillars must be simultaneous.

Three Pillars
1. Safety: 1:1 observation, remove weapons and sharps, locked unit
2. Duty to warn (Tarasoff): notify the identified victim and law enforcement
3. Means restriction: firearm storage off-site, family lockup, or temporary surrender to law enforcement — the single most effective intervention

Disposition
Almost always inpatient psychiatric admission (voluntary preferred, involuntary if refused).

Wrong Answers
4: Confidentiality has limits when third-party harm is foreseeable.
5: Vague documentation creates legal jeopardy.
6: Outpatient follow-up is insufficient for active HI with means.

NCSBN Theme
PSI — Crisis intervention / behavioral health emergency.

## Clinical scenario

Scenario
38-year-old, voluntary ED presentation, homicidal ideation.

Risk Profile
- Specific target: identified co-worker
- Plan: confront at office tomorrow
- Means: handgun at home
- Stated escalation: thoughts getting stronger
- Insight present: client does not want to act

Crisis Tier
High imminence. Tarasoff threshold met. Means restriction critical.

Required Actions
Safety plus duty to warn plus means restriction plus inpatient psych.

## Key concepts

- **Tarasoff duty to warn** — Legal duty arising from Tarasoff v. Regents of the University of California (1976) — when a clinician determines that a client poses a serious danger of violence to an identified third party, the clinician has an obligation to take reasonable steps to protect the intended victim, which may include warning the victim, notifying law enforcement, or pursuing involuntary commitment. Specific requirements vary by state.
- **Means restriction** — Limiting access to lethal means (firearms, medications, sharps, height) for individuals at acute risk of harm to self or others. Strongest evidence base in suicide prevention but applies equally to homicidal risk. Methods: voluntary off-site storage with family or friend, gun shop or law enforcement temporary surrender, gun safes with combinations held by another, medication lockboxes.
- **Homicidal ideation assessment** — Structured evaluation of imminent violence risk: identified target (specific person versus generalized), plan (method and timing), means (weapons access, especially firearms), preparatory actions, intent (passive thoughts versus active wish), insight, history of violence, substance use, command hallucinations. Disposition follows acuity — most acute cases require inpatient admission.
