Suicide Risk: Assessment, Observation and Safety

Mental Health · Crisis Intervention·Updated 2026-10-28

What it is

Suicide risk rises with hopelessness, a specific plan, access to lethal means, a prior attempt, substance use and recent loss. Asking directly about suicide does not plant the idea; it opens the conversation and is the nurse's first assessment step. The level of risk, not the diagnosis, determines the level of observation and the safety plan.

What the NCLEX focuses on

Ask directly: "Are you thinking about killing yourself?" Then assess plan, intent, means, timing and prior attempts.
A prior attempt is the strongest predictor of suicide; a specific, lethal plan with available means indicates high risk.
Warning signs: giving away possessions, putting affairs in order, saying goodbye, and sudden calm after severe depression, which signals a decision to act.
Antidepressants carry a boxed warning for increased suicidal thinking in clients under 25; risk rises in the first weeks as energy returns before mood lifts.
A plan with means or intent requires continuous 1-to-1 observation; passive thoughts without a plan are managed with observation per policy and frequent reassessment.
Remove belts, shoelaces, cords, plastic bags, sharps and glass; search belongings and confirm oral medications are swallowed.
A written safety plan replaces no-suicide contracts, which do not prevent suicide.

Priority nursing actions

Stay with a client in imminent danger and remove any means of harm.
Ask directly about suicidal thoughts, plan, intent and access to means.
Start the observation level that matches the risk and notify the provider.
Make the environment safe: remove ligature points and dangerous items.
Build a collaborative safety plan with the client and family, including the 988 Suicide and Crisis Lifeline.
Reassess risk at every contact, especially as energy improves and before discharge.

Numbers to know

Finding	Meaning	Nursing action
Passive wish to not wake up, no plan	Suicidal ideation	Assess further; observation per policy; safety plan
Specific plan and access to means	High risk	Continuous 1-to-1 observation; notify provider
Plan with a time ("tonight")	Imminent risk	Stay with client; remove means; 1-to-1
Sudden calm after severe depression	Possible decision to act	Reassess for a plan; do not reduce observation
First weeks of antidepressant therapy	Energy returns before mood	Monitor closely; boxed warning under age 25
988	Suicide and Crisis Lifeline (call or text)	Include in every safety plan

Common exam traps

Choosing to avoid the word "suicide" so the idea is not suggested: wrong because direct questions reduce risk and are required for assessment.
Choosing to reduce observation for a depressed client who is suddenly cheerful: wrong because sudden calm signals a possible decision to act.
Choosing a no-suicide contract as the safety intervention: wrong because contracts do not prevent suicide; use a safety plan and observation.
Choosing hourly checks for a client with a plan and means at home: wrong because high risk requires continuous 1-to-1 observation.
Choosing to keep a disclosure of suicidal intent secret: wrong because safety overrides confidentiality; the team must know.

What to teach

Teach family the warning signs and to call 988 or 911 for immediate danger.
Remove or lock up firearms and medications at home.
Antidepressants take several weeks to lift mood; report new or worsening suicidal thoughts at once.
Keep the written safety plan where the client can reach it, and keep follow-up appointments.

Question 1 · QID AF201AC0

The nurse is assessing suicide risk in several clients. For each statement, indicate whether it supports standard observation or continuous 1-to-1 observation.

For each client statement, indicate the level of observation it supports.

	Standard observation	Continuous 1-to-1 observation
"I feel hopeless most days, but I don't have any thoughts of hurting myself."
"I know exactly how I would do it and I have everything I need at home."
"I have the pills counted out and I'm planning to take them tonight."
"Sometimes I wonder what it would be like to not wake up, but I would never act on it."

Question 2 · QID 1C09BCB2

A client who has been severely depressed and tearful for weeks suddenly appears calm and cheerful, telling the nurse, "I finally feel at peace." Which action should the nurse take?

Select the best answer.

A. Assess further for a possible plan to attempt suicide
B. Acknowledge the calmer mood and ask which recent treatment changes or coping strategies the client feels have contributed to the improvement
C. Consider decreasing observation after confirming that the client remains calm, cooperative, and engaged with the treatment plan throughout the shift
D. Document the sudden improvement in mood and continue close therapeutic observation while monitoring whether the change remains consistent over the next several hours
