The conditions, the settings, and the decisions nobody enjoys making
The first part of this subject taught the work that is done with words — communication, assessment, risk, the mental state, and the common presentations. This part takes up what comes after: the conditions that run for years rather than weeks, the settings where most mental health care actually happens, and the decisions that involve doing something to a person who does not want it done. Those decisions are the hardest thing in nursing, and they are made most often by the person physically present, which is almost always a nurse. A student who has thought about them beforehand makes them better than one meeting them for the first time at two in the morning.
The first part of this subject dealt with assessment, communication and the common presentations as they appear in a first meeting. Most mental illness, however, is not a single episode. It recurs, it fluctuates, it interacts with physical illness and with poverty, and it is lived with for decades. This part is about that longer arc, and about the settings where it actually plays out, which are far more often homes and clinics than wards.
For most of the world there is no specialist psychiatric service within reach, and mental health care is delivered by general nurses, community health workers and family doctors alongside everything else they do. Any account of this subject that assumes a multidisciplinary team, an inpatient bed and available therapy describes a minority of practice. This manual tries to be useful in both situations.
This part deals directly with restraint, seclusion, compulsory treatment and the refusal of care, because those are the points at which nursing does something to a person against their stated wish. They are the hardest decisions in the profession, they are frequently made at night by whoever is present, and thinking about them in advance is the only preparation available.
Recovery in mental health does not necessarily mean the absence of symptoms. It means a life the person regards as worth living, with as much control and as much ordinary participation as possible, whether or not the illness has gone. This reframing changes what counts as a good outcome, and therefore changes what nursing aims at.
A single depressive episode frequently becomes a recurring pattern, and each episode raises the likelihood of another. This changes the nursing conversation from getting through this episode to recognising the person's own early warning signs, keeping treatment going after they feel better, and planning what they and their family will do when the signs appear again.
Some people experience periods of elevated mood, reduced need for sleep, rapid speech, grand plans and impaired judgement, alternating with depression. The elevated phase is often experienced as feeling well, which is why insight is limited and why treatment is frequently stopped during it. Sleep loss is both an early sign and a driver, which makes sleep one of the most useful things to ask about.
People with severe mental illness die substantially earlier than the general population, mostly of ordinary physical causes — heart disease, respiratory disease, diabetes, cancer — that were detected late or treated less thoroughly. This is one of the clearest health inequalities there is, and general nurses are in the best position to close it by treating physical complaints from these patients with the same seriousness as anyone else's.
When a person with a known mental illness reports a physical symptom, it is systematically more likely to be attributed to their psychiatric condition and less likely to be investigated. This has a name because it happens often enough to need one, and it kills people. The corrective is simple to state and hard to practise: investigate the physical complaint first, then consider the psychiatric explanation.
Outcomes are substantially better when a first episode of psychosis is treated early, and worse the longer it goes untreated. Since first episodes typically occur in late adolescence and early adulthood, the people most likely to encounter them first are family, teachers and general health workers rather than psychiatric services. Recognising and referring quickly is therefore a general nursing skill.
Between acute episodes, what commonly remains is not hallucination but reduced motivation, flattened emotional expression, social withdrawal and difficulty with planning and memory. These are frequently mistaken for laziness or rudeness, including by staff, and they respond poorly to the treatments that help acute symptoms. They also determine whether someone can hold work, study or relationships, which is what the person usually cares about most.
Relapse usually has a warning period, and the signs are often idiosyncratic — a particular change in sleep, a withdrawal from a specific routine, a return of a particular preoccupation. The person and their family frequently know these better than any professional. Writing them down while the person is well, together with what they want done, is one of the highest-value interventions in this whole manual.
Medicines used in psychosis produce effects that nurses are expected to notice: movement disorders of several kinds, some appearing early and some after long use, sedation, weight gain, effects on glucose and on the heart, and a rare but rapidly dangerous reaction involving fever, rigidity and confusion. Knowing what to watch for and escalating quickly is nursing work regardless of who prescribed.
Self-harm and attempted suicide overlap but are not identical. Self-harm is frequently a way of managing unbearable feeling rather than an attempt to die, and treating every instance as a failed suicide attempt misreads the person. At the same time, self-harm is one of the strongest predictors of later suicide, so it is never dismissed as attention-seeking either. Both errors are common and both are harmful.
Asking a person directly whether they are thinking of ending their life does not plant the idea, and this is one of the most firmly established findings in the field. Vague questions get vague answers. Asking plainly, without alarm, and then asking about plan, means and intent, is what produces usable information, and most people answer honestly when asked properly.
The measures with the best evidence are unglamorous: restricting access to the means, treating the underlying illness, follow-up contact after an episode of self-harm, responsible reporting in media, and reducing harmful alcohol use. Restricting means works because much suicidal crisis is short-lived and highly specific to a method, which is not intuitive but is well supported.
People who attend after self-harm frequently report being treated with hostility or indifference, and that experience reduces the likelihood of seeking help next time. The way a nurse speaks to someone during wound care after self-harm is not a soft skill beside the clinical care; for this patient's future it may be the most consequential part of the encounter.
When a patient dies by suicide, the staff involved are affected, and pretending otherwise produces the silence that stops people asking for help. Reviews that look for a person to blame guarantee that the next near-miss is concealed. Reviews that ask what made the outcome possible produce information, and they are also the humane option.
Anxiety is normal and useful; it becomes a disorder when it is out of proportion, persistent, and limiting what the person can do. The physical symptoms are real and physiological — racing heart, breathlessness, tremor, gut upset — which is why so many people with anxiety disorders present repeatedly to physical health services and are investigated repeatedly for a heart or gut problem.
Obsessions are intrusive, unwanted thoughts that the person recognises as their own and finds distressing; compulsions are acts performed to reduce that distress. The relief is brief, which is precisely why the cycle strengthens. Reassuring the person or helping them complete the compulsion feels kind and makes the condition worse, which is a genuinely difficult thing for a nurse to sit with.
Following a severe threat, some people develop persistent re-experiencing, avoidance, a sense of constant threat and changes in mood and thinking. Re-experiencing is not remembering; it is the event intruding with its original intensity. Understanding that difference explains why a patient may react to a smell, a sound or a procedure in a way that appears disproportionate and is not.
In practice this means predictability and control: explaining before touching, offering choices about position and timing, allowing someone to stop, avoiding restraint where any alternative exists, and recognising that intimate examinations and procedures can be re-traumatising. None of it requires knowing the person's history, which is fortunate, because usually you will not.
Eating disorders carry among the highest mortality of any psychiatric condition, from both physical complications and suicide. The physical risks — heart rhythm disturbance, salt abnormalities, bone loss, and the dangers of feeding someone after prolonged starvation — mean that physical monitoring is a central part of care rather than a background task.
The behaviour concerns food and weight; the illness usually concerns control, self-worth and distress. This is why arguments about eating rarely work and why a patient can be highly knowledgeable about nutrition while gravely ill. The nursing stance that helps is consistent, warm and non-negotiating about the agreed plan, which is easier to describe than to sustain.
Feeding a severely undernourished person too quickly drives salts rapidly out of the blood into cells and can cause heart failure, seizures and death. This is a well-described danger with a defined protocol, and it is the reason nutritional restoration in these patients is slow, supervised and monitored with blood tests rather than driven by how much weight needs to be regained.
Families are frequently exhausted, frightened and blamed, and in younger patients their involvement in treatment improves outcomes substantially. Working with them rather than around them is both more effective and more decent, and it requires a nurse to tolerate being present while a family is distressed without needing to fix it immediately.
Repeated use of certain substances produces physical adaptation, so stopping causes withdrawal, and changes in the brain's reward systems that make continued use feel necessary rather than chosen. Understanding this changes the tone of every conversation, and tone determines whether a person tells you the truth about how much they are using, which is the information you actually need.
Withdrawal from alcohol and from certain sedatives can cause seizures and a severe confusional state with a real mortality, and is managed medically rather than by willpower. Withdrawal from opioids is intensely unpleasant and rarely directly fatal. Knowing which is which determines urgency, and getting it the wrong way round is a recognised and dangerous error.
Where someone is not going to stop, reducing the damage is a legitimate and evidence-supported aim: safer injecting practice, avoiding using alone, vaccination, treatment of blood-borne infection, and access to reversal agents for overdose. This is uncomfortable for people who feel it condones use, and it keeps people alive long enough to change.
Mental illness and substance use frequently occur together, each worsening the other, and services are often organised so that each declines to treat the person until the other problem is dealt with. This gap is where a large number of people are lost, and the practical nursing response is to keep the person engaged with somebody rather than to enforce the boundary.
Mental illness in pregnancy and the year after birth is common, and in several countries mental health causes are among the leading causes of maternal death in that period. It is missed because attention is on the baby, because women fear the consequences of disclosure, and because low mood is assumed to be normal exhaustion.
Brief tearfulness and mood swings in the first days after birth are common and settle. Depression persisting beyond that, with inability to enjoy the baby, hopelessness or thoughts of harm, is not, and needs assessment. The distinction matters because reassuring a depressed woman that this is normal is a delay with real consequences.
A small number of women develop a severe illness within days of birth, with confusion, rapidly changing mood and beliefs that may involve the baby. It develops fast, it is a psychiatric emergency, and it is one of the few situations in this manual where the correct action is immediate escalation rather than assessment and planning.
Women frequently fear that disclosing distress will result in the baby being removed, and that fear is not irrational. Explaining what will and will not happen, asking routinely of everyone rather than selectively, and treating the answer without alarm are what make honest answers possible. A question asked in a way that predicts punishment is not a screening question.
Younger children express distress through behaviour, physical complaints, regression and play rather than through describing feelings. Adolescents may present with irritability rather than sadness, with risk-taking, or with school refusal. Applying adult descriptions of illness to children produces both missed cases and wrong labels.
A large majority of lifetime mental illness begins before early adulthood, which is why services aimed at young people have a disproportionate effect and why they are so often the least funded. It also means that a nurse working with young people is frequently seeing the beginning of something, with the best opportunity to change its course.
Work with a young person involves family, school and sometimes social services, and the young person's own confidentiality has to be balanced against safety and against the rights of those with parental responsibility. The balance differs by age, by jurisdiction and by risk, and the honest position is that this is genuinely difficult and is not resolved by a rule.
Self-harm is common among adolescents and is frequently dismissed as attention-seeking or as contagious behaviour. It is a marker of genuine distress and of later risk, and it requires the same assessment as in adults with additional attention to what is happening at home and at school, which is usually where the answer is.
Low mood in older people is frequently accepted as an understandable response to age, loss and illness, and therefore left untreated. It is common, it is treatable, and it presents more often with physical complaints, agitation or memory difficulty than with expressed sadness, which is exactly why it is missed.
These three are confused constantly and are distinguished mainly by time course and attention. Delirium develops over hours or days with fluctuating attention and is caused by something physical. Dementia develops over months to years with relatively preserved attention early. Depression can impair concentration and mimic both. Getting this wrong means a treatable physical cause is missed.
Delirium indicates that something physical is wrong — infection, pain, retention, constipation, dehydration, a medicine, withdrawal — and it carries a real mortality. The nursing response is to look for the cause, treat the physical problem, and manage the environment with orientation, familiar people, sleep, glasses and hearing aids, rather than to sedate a confused patient as a first resort.
Behaviour described as challenging in dementia is usually communication of an unmet need — pain, needing the toilet, fear, noise, hunger, boredom, or being handled without warning. Looking for the need first, rather than treating the behaviour, resolves a substantial proportion of it and avoids medicines that carry real harm in this group.
Any intervention that limits a person's freedom must be the least restrictive that will achieve safety, used for the shortest time, and stopped as soon as it is no longer needed. This principle appears in law and guidance across very different countries, and it is the single most reliably examined idea in this part of the subject.
Physical restraint causes injury and death, including from restricted breathing when a person is held face down or with pressure on the chest, and the risk is higher in people who are exhausted, intoxicated, physically unwell or have been struggling for some time. Treating restraint as a safe default because it feels decisive is how people die during it.
Giving a sedating medicine in order to control behaviour rather than to treat illness is a restrictive intervention, and it is governed by the same principles as physical restraint: necessity, proportion, the least restrictive option, monitoring afterwards and review. It is frequently not recorded as a restrictive practice at all, which hides it from the review processes that exist to reduce restriction. Physical observation afterwards is essential, because sedation carries risks to the airway, to breathing and to blood pressure that are easy to miss in a person who now appears settled.
Most restraint follows a period during which the situation could have gone differently: unmet requests, long waits, noise, lack of information, being ignored, and staff responses that escalated rather than reduced tension. Reviewing incidents for what preceded them, rather than only for whether the hold was correct, is what actually reduces their number.
After any episode of restraint or seclusion the person is offered the chance to talk about what happened, the episode is recorded and reviewed, and physical observation continues because injury is common and sometimes unrecognised. Skipping the conversation because it is uncomfortable leaves the person with the experience and no account of it.
Every country permits treatment without consent under defined circumstances, and the circumstances, the safeguards and the appeal routes differ fundamentally. What does not differ is that it is an exception requiring justification, that the person retains rights throughout, and that the nurse's role includes making sure the person knows what those rights are.
A person may have capacity to decide one thing and not another, and capacity can change through the day and with illness. It is assessed for the decision in question at the time it is being made, not assigned as a general status, and a diagnosis never establishes its absence by itself.
A person is entitled to make choices others consider foolish, and doing so is not evidence that they cannot decide. The test concerns the process — whether they can understand, retain, weigh and communicate — not the outcome. This is the distinction most commonly got wrong in practice and most commonly examined.
Before concluding somebody cannot decide, everything practicable is done to help them: plain language, an interpreter, information in stages, choosing a time when they are least confused, involving someone they trust, and using written or pictorial aids. Capacity assessments performed without these steps frequently find incapacity that better communication would have removed.
People with recurring mental illness can record, while well, what they want to happen if they become unwell — treatments they prefer or refuse, who should be told, practical arrangements for dependants and pets. The weight this carries in law differs by country, and its value in reducing conflict and distress does not depend on that weight.
Most mental health care happens outside hospital, delivered in homes, clinics and primary care, over years. The defining feature is continuity — the same person, known over time, noticing changes. That relationship is the intervention in a way that is difficult to measure and easy to dismantle through service reorganisation.
The periods of highest risk are immediately after discharge from hospital and immediately after an episode of self-harm. Contact soon after, rather than an appointment in six weeks, is what the evidence supports. Arranging and protecting that contact is frequently a nursing responsibility and is frequently the thing that gets lost.
Housing, income, work, safety, immigration status and isolation influence mental health powerfully, and a treatment plan that ignores them addresses the smaller half of the problem. Helping with a housing letter or a benefits form is not outside nursing in this field; it is frequently the intervention with the largest effect.
Where specialist services do not exist, structured approaches allow non-specialists to assess and manage common mental disorders, and they work. The principles are recognition, brief structured intervention, limited well-defined medicine use, follow-up and clear referral criteria. This is the reality for most of the world, and it is not a lesser version of the subject.
Stigma delays help-seeking, reduces disclosure, damages employment and relationships, and affects the quality of physical health care people receive. It is not a peripheral social concern; it is a determinant of outcome, and it operates inside health services as strongly as outside them.
People absorb the attitudes around them and apply them to themselves, concluding that they are dangerous, useless, a burden, or beyond help. This self-directed version predicts withdrawal from treatment, from work and from relationships, and it is reinforced every time a professional speaks about them as a case rather than a person. It is also reduced by very ordinary things — being spoken to normally, being asked about work and family, being treated as somebody with a life rather than a diagnosis — which is a genuine intervention available to every nurse at no cost.
Health workers contribute through language, through tone, through where patients are placed and how long they wait, through assuming that a physical complaint is psychiatric, and through conversations held within earshot. Most of it is unintentional, which is why it persists, and why noticing it in oneself is the only available correction.
Describing a person by their diagnosis, using the diagnosis as an adjective, and words implying blame or danger all carry weight, particularly in records that other clinicians will read years later. Terms differ between countries and change over time, and the reliable rule is to describe what the person does and experiences rather than labelling what they are.
Because disclosure carries real social cost in many communities, confidentiality in mental health is not only an ethical duty but a practical protection that determines whether people attend at all. A service known to be discreet reaches more people, and a single breach travels further than any amount of outreach.
Repeated exposure to distress, risk and occasionally to violence has a cumulative effect, and the professional consequence is emotional exhaustion, detachment and reduced effectiveness. It is a predictable occupational effect rather than a personal weakness, and treating it as weakness is exactly what prevents people asking for help early.
Regular structured reflection on cases with a supervisor is standard in this field because decisions are difficult, ambiguous and emotionally loaded. It is the mechanism by which judgement improves and by which the effect of the work is noticed before it becomes damage. Where it is not provided, finding an informal equivalent is worth the effort.
Staff involved in a suicide, a serious assault or a restraint that went wrong need time, an accurate account and support, and organisations frequently provide a process that examines the incident and not the people. Both are necessary, and the absence of the second reliably produces silence around the first.
Long relationships with distressed people generate genuine warmth and genuine pressure to do more than the role allows. Clear boundaries protect the patient more than the nurse, because a relationship that becomes personal cannot be handed over, cannot be sustained, and ends in a loss the patient did not agree to.
Nurses rarely deliver formal psychological therapy, and constantly meet patients who are waiting for it, receiving it, have refused it or have been discharged from it. Knowing roughly what each approach asks of a person allows a nurse to explain it honestly, to recognise when somebody has been offered something that does not fit them, and to avoid the common error of describing therapy as simply talking about your problems.
Several well-evidenced therapies work by examining the link between what a person thinks, how they feel and what they then do, and by deliberately changing the behaviour to test the thought. They are structured, time-limited, involve work between sessions, and require the person to do something rather than only to attend. That last point is worth saying in advance, because people who expect to be listened to and are instead given tasks frequently disengage.
Other approaches focus on patterns in relationships, on early experience, and on what is happening in the room between person and therapist. They are typically longer and less structured. Neither family of approaches is universally superior; the useful question is what this person can engage with, what is actually available, and whether anybody has asked them what they want.
Without being a therapist, a nurse can offer structured problem-solving, activity scheduling for someone whose life has contracted, sleep and routine work, psychoeducation about the illness, and brief structured interventions of the kind designed for non-specialist delivery. These are real interventions with evidence behind them, and in most of the world they are the only ones available.
People with mental illness are far more likely to be the victims of violence than the perpetrators of it, and the public perception is close to the opposite. Holding that fact clearly is important, because acting on the perception produces excessive restriction of people who present no danger, while the small number who do present risk are identified by assessment rather than by diagnosis.
The strongest predictors are a history of violence, current substance use, active symptoms that involve threat or command, recent discontinuation of treatment, and the immediate situation — being frightened, cornered, in pain, or not listened to. Diagnosis alone predicts poorly. Assessment therefore asks about history and current state rather than resting on a label.
Where a specific person is threatened, confidentiality gives way to a duty to protect, and the thresholds and procedures differ between countries. What does not differ is that the decision is documented, is taken with senior input wherever time allows, and discloses the minimum necessary to the people who need it rather than broadly.
Some patients are treated in secure settings because of offending linked to illness. The nursing task there is the same clinical work carried out under continuous tension between care and custody, and the main professional risk is drifting into a custodial identity in which security decisions stop being clinically justified. Naming that tension openly is how teams resist it.
People consistently rate work, housing, relationships and having something to do above symptom reduction when asked what matters to them. Services organised entirely around symptoms therefore succeed by their own measure while the person's life continues to shrink. Asking what the person wants their week to look like is a clinical question, not a pleasantry.
Employment improves mental health for most people, and the approaches with the best evidence place people into ordinary jobs with support rather than training them indefinitely in preparation. Fear of losing benefits, gaps in employment history and disclosure decisions are the practical obstacles, and helping with those is more useful than encouragement.
Depression, psychosis and long admissions all contract a person's activity until very little remains, and inactivity then maintains the low mood and the isolation. Rebuilding deliberately — one activity, at a set time, small enough to succeed at — is a recognised intervention rather than a suggestion, and it is something a nurse can do with somebody in ten minutes.
Relatives provide most of the day-to-day care in this field, often for decades, usually without training and frequently while being excluded from decisions on confidentiality grounds. They have their own needs and their own right to information about how to help, and involving them is associated with better outcomes. Where the patient objects, what can still be discussed in general terms is more than most staff assume.
In this field, records are read years afterwards by people who never met the patient, and sometimes by the patient themselves. Words implying blame, danger or dislike travel with the person and change how they are treated. Recording what was said and observed, in the person's own words where possible, is both more accurate and more defensible than recording an impression.
Risk changes and a handover that repeats a risk level from three weeks ago is worse than none, because it carries authority it has not earned. What is useful is what has changed, what the person said today, what was agreed, and what specifically to watch for. A level without a reason cannot be acted on.
Teams in this field disagree frequently about risk, about capacity and about restriction, and that disagreement is often productive because the different disciplines see different things. What matters is that the disagreement is recorded and resolved through a process rather than by seniority alone, and that the person and their family are not caught between two plans.
Nurses are present continuously and therefore hold information nobody else has: how the person is at three in the morning, what they said while their hair was being washed, who visited and what changed afterwards. That information is frequently the most predictive available, and it reaches decisions only if it is written down and said aloud in the meeting.
A learning disability is a lifelong difference in intellectual functioning and everyday skills; autism is a lifelong difference in how a person communicates, relates and processes sensory information. Neither is a mental illness, and treating them as such is a persistent error. People with either can also develop mental illness, at higher rates than the general population, and that illness is frequently missed because the presentation is attributed to the disability instead.
Where a person communicates little through speech, pain, illness, fear and unmet need are expressed through behaviour — agitation, withdrawal, self-injury, aggression. The professional habit that matters most is to look for a physical cause first every time: toothache, constipation, ear infection, injury, a full bladder. Behaviour that changes suddenly in someone whose behaviour is usually stable is a physical question until proved otherwise.
Small, specific changes make health care possible: longer appointments, a quiet room, dimmed light, avoiding waiting areas, one clinician rather than many, explaining each step before touching, allowing a familiar person to stay, and using pictures or written information. These are not courtesies; in many countries they are a legal requirement, and without them people simply do not attend.
For many autistic people, ordinary hospital sensory input — fluorescent light, alarms, overlapping conversation, strong smells, unexpected touch — is genuinely painful rather than merely unpleasant. Distress that follows is frequently recorded as challenging behaviour when it is a predictable response to an environment nobody adjusted. Asking in advance what the person finds difficult takes two minutes and prevents most of it.
People with learning disabilities die substantially younger than the general population, and reviews repeatedly find the same avoidable causes: diagnostic overshadowing, failure to make adjustments, poor communication between services, and assumptions about quality of life influencing decisions about treatment. Knowing that this pattern exists is the beginning of not contributing to it.
The reliable topics are least restrictive practice, capacity including that an unwise decision is not incapacity, asking directly about suicidal thoughts, distinguishing delirium from dementia and depression, and the physical health gap in severe mental illness. These recur across papers because they are principles rather than local law.
Examiners reward answers that assess before acting, that choose the least restrictive option available, that involve the person in the decision, that escalate appropriately, and that address physical causes before psychiatric explanations. An answer that reaches for restraint or sedation early will lose marks almost everywhere, including where practice locally is different.
Questions involving detention or compulsory treatment are set against the law of the country administering the examination. Learn your own law properly, and in an international paper answer on the principles — necessity, proportionality, least restriction, review and appeal — which hold almost everywhere.
Ask about suicidal thoughts directly. Investigate the physical complaint before attributing it to the diagnosis. Look for the unmet need before treating the behaviour. Write down the person's own early warning signs while they are well. Each of these is small, none requires a specialist service, and together they are most of what this manual is for.
