Suicide Risk Assessment & Precautions

The most dangerous moment for a suicidal patient isn't when they're most depressed — it's when they suddenly seem better. Missing that window can be fatal.

Suicide risk assessment is a continuous nursing responsibility, not a one-time screening. The highest-risk period is when a depressed patient's energy returns before their hopelessness lifts — they now have the motivation to act on existing suicidal ideation. This is why patients starting antidepressants or being discharged from inpatient care require intensified monitoring. Assess using structured questioning: move from broad ("Have you thought about hurting yourself?") to specific ("Do you have a plan? Access to means?"). A specific plan with available means and a timeline signals imminent risk. Protective factors (reasons for living, social support, future orientation) lower but never eliminate risk. Suicide precautions include one-to-one observation, removing sharps, belts, cords, glass, and plastic bags from the environment, checking belongings on admission, and documenting every 15-minute safety checks (or continuous observation for imminent risk). Contracts for safety are NOT evidence-based and should never replace direct observation. The nurse documents mood, statements, and behaviors objectively — not just "patient denies SI."

Key Distinctions

Don't confuse a "no-harm contract" with adequate precaution — contracts have no evidence base and give false reassurance. Students often think the most depressed phase is highest risk, but rising energy with persistent hopelessness is the danger zone. Environmental safety means removing ALL potential ligature points, not just obvious weapons — shower rods, bed linens, and electrical cords are common means on inpatient units.

Clinical Pearl

Sudden calmness in a previously agitated suicidal patient may mean they've made a decision to act — escalate observation immediately, don't celebrate improvement.
