Nursing intervention begins with lethality assessment: suicide, homicide or violence risk is checked before anything else, followed by rapid rapport, defining the problem from the person's own view, mobilising resources and short-term follow-up. Crisis work is brief and present-focused, and its psychiatric extensions — de-escalation of aggression, safe restraint as a last resort, care of rape and disaster survivors with psychological first aid — are all structured skills rather than intuition. ## What you must remember - Crisis types: situational or dispositional (job loss, bereavement, unwanted pregnancy), maturational (developmental transitions such as marriage, retirement, adolescence) and adventitious (disasters, accidents, crime). - A crisis typically resolves within 4 to 6 weeks; the person either returns to pre-crisis functioning, adapts at a higher level, or decompensates — timing defines the intervention window. - Step sequence: assess danger and lethality first, ensure safety, establish rapport, define the problem, encourage expression of feelings, explore past coping and alternatives, build an action plan, and follow up. - Suicide precautions: never leave the person alone, remove means, one-to-one observation, and re-assessment after any intervention, because risk fluctuates hour to hour. - De-escalation ladder: approach calmly with respectful tone, keep distance and an exit path, remove the audience and noise, offer food, drink or a quieter space, offer PRN medication early; restraint and seclusion are always last resorts. - Physical restraint or seclusion per the Mental Healthcare Act 2017: least restrictive method, physician order, documented rationale, physical monitoring at short intervals, release at the earliest, and never as punishment or convenience. - Psychological first aid follows look, listen, link — safety, calm contact, practical support and referral — without forcing debriefing of details. - Rape and trauma care is survivor-centred: consent at every step, preservation of forensic evidence before washing or changing clothes, prophylaxis against pregnancy and sexually transmitted infections, and mandatory reporting when the survivor is a child under POCSO. ## A typical exam case A young woman is brought to the emergency department at 2 a.m. after taking a fistful of her mother's tablets during a family quarrel; she is medically stable and refusing to speak. The nursing sequence the exam expects: she is never left alone, means of further harm are removed from reach, and the assessment opens with direct, calm questions about current intent — not with "why did you do it". Rapport is built by naming the overwhelm rather than interrogating the act; the problem is defined in her words (the quarrel, a broken relationship), her previous coping is explored, and a short list of immediate options is generated with her — telling a trusted aunt, a helpline number, a follow-up appointment within 24 to 48 hours. The plan is written, one copy with her. Contrast the second framing in the same paper: an agitated young man pacing the ward corridor, shouting. The correct ladder is one nurse speaking calmly at an angle with space respected, stimulation and audience reduced, needs offered — food, phone call, PRN medicine — and only if he endangers himself or others, a physician-ordered restraint with monitoring every 15 minutes and documentation of behaviour before, during and after release. Students who choose "call security and restrain" as the first action fail the item, because least-restrictive comes first. ## Where students slip The commonest wrong answer is choosing counselling depth over safety: in any stem combining suicide risk with emotional needs, lethality assessment wins the "first action" question. Students also confuse crisis with mental illness — crisis intervention is for anyone, is short-term and present-focused, unlike psychotherapy — and forget the 4 to 6 week self-limiting course that MCQs quote verbatim. In grief questions, the tested distinction is that normal grief comes in waves with preserved self-esteem, while depression is pervasive with worthlessness. Restraint questions are lost on details: the order, the documentation and the short-interval physical monitoring are the scored elements, not the type of hold. ## Frequently asked questions ### What is the first step in crisis intervention? Assessment of lethality — danger of suicide, homicide or violence — and ensuring immediate safety before any counselling begins. ### How long does a crisis state usually last? Four to six weeks, during which the person returns to previous functioning, adapts, or decompensates; intervention is brief and focused within this window. ### What are the three types of crisis? Situational (external events like loss or disaster), maturational (developmental transitions) and adventitious (catastrophic events such as disasters and crime). ### When may a nurse physically restrain a psychiatric patient? Only as the least-restrictive last resort for imminent danger, with a physician order, close physical monitoring, documentation and release at the earliest, per the Mental Healthcare Act 2017. ### What does psychological first aid involve? Look, listen and link — ensuring safety and calm, active listening without pressing for details, and connecting survivors to support, information and services.
