Nursing Process in the Management of Mental Health Patients
The nursing process is a systematic, person-centred and cyclical method of assessing needs, identifying nursing problems, planning measurable outcomes, implementing individualized interventions and evaluating response.
In mental-health nursing, the process joins physical assessment, mental-state examination, risk formulation, therapeutic relationship, medicine care, psychological support, social context and recovery goals. It is not a form completed once on admission; it changes whenever risk, symptoms or functioning changes.
Purposes
- Prevent important needs from being missed during complex or rapidly changing presentations.
- Prioritize immediate danger before long-term rehabilitation.
- Make nursing actions individualized, measurable and accountable.
- Coordinate patient, family and multidisciplinary contributions.
- Evaluate whether care produced benefit, harm or no change.
- Provide continuity across shifts, referral and discharge.
Step 1: Assessment
Immediate safety and medical assessment
Start with the urgency of the presentation. Use ABCDE for collapse, overdose, injury, intoxication, withdrawal, seizure, altered consciousness or severe agitation. Check glucose and relevant vital signs, identify pregnancy and medical comorbidity, and do not assume that abnormal behaviour is purely psychiatric.
Psychiatric history
- Presenting problem: Onset, duration, triggers, severity, progression, effect on daily life and the patient’s explanation.
- Symptoms: Mood, anxiety, psychosis, cognition, sleep, appetite, energy, behaviour and somatic complaints.
- Risk: Suicidal thoughts, intent, plan, means, attempts; violence; vulnerability; self-neglect; absconding; substance use and safeguarding.
- Past history: Previous episodes, admissions, self-harm, violence, treatment, response and adverse effects.
- Medical history: Neurological/endocrine illness, infection, pain, reproductive status, medicines, allergies and disabilities.
- Personal/social history: Development, education, occupation, relationships, housing, finances, legal issues, trauma, culture, faith and supports.
- Substance history: Substance, amount, frequency, last use, dependence features, withdrawal, complications and readiness to change.
- Strengths: Skills, protective relationships, values, coping strategies, treatment preferences and recovery goals.
Mental-state examination
| Domain | What to observe/ask | Example documentation |
|---|---|---|
| Appearance and behaviour | Dress, hygiene, eye contact, cooperation, activity, abnormal movements | “Dishevelled, pacing, intermittently scanning room; accepts interview near doorway.” |
| Speech | Rate, volume, amount, spontaneity and coherence | “Rapid, loud and difficult to interrupt.” |
| Mood and affect | Subjective mood; observed range, reactivity and congruence | “Reports sadness 8/10; affect constricted and congruent.” |
| Thought | Form, flow, content, delusions, hopelessness, obsessions, suicide/homicide ideas | Record the person’s relevant words and degree of conviction. |
| Perception | Hallucinations, illusions, depersonalization and response | “Reports a male voice commanding self-harm; appears distracted.” |
| Cognition | Alertness, orientation, attention, memory and executive ability | Fluctuation and inattention raise concern for delirium. |
| Insight/judgment | Understanding of change/illness, need for care and safe decision-making | Describe what the patient understands rather than writing “no insight” alone. |
Risk formulation
A checklist score does not replace clinical judgment. State: current risk; static and dynamic factors; protective factors; foreseeable situations that increase risk; and a management plan. Example: “High immediate suicide risk due to current intent, available pesticide and command hallucinations; partially protected by help-seeking and supportive sister. Requires constant observation, removal of means, urgent medical/psychiatric review and collaborative safety planning when able.”
Step 2: Nursing diagnosis/problem identification
A nursing diagnosis describes a human response that nursing can independently monitor or address. Use approved terminology where required, but ensure it is supported by assessment data. Distinguish it from a medical diagnosis.
| Type | Structure | Example |
|---|---|---|
| Actual problem | Problem related to contributing factor as evidenced by findings | Disturbed sleep pattern related to hyperarousal as evidenced by sleeping two hours nightly and daytime fatigue. |
| Risk diagnosis | Risk for problem related to risk factors; no “as evidenced by” because it has not occurred | Risk for suicide related to current intent, previous attempt, command hallucinations and access to poison. |
| Health promotion | Readiness to improve a health behaviour | Readiness for enhanced treatment self-management. |
Prioritization
- Life-threatening physical instability, overdose, withdrawal, injury or seizure.
- Immediate suicide, violence, severe vulnerability or safeguarding danger.
- Severe self-neglect, dehydration, malnutrition, sleep loss or inability to function.
- Distressing symptoms and medicine adverse effects.
- Knowledge, coping, relationships, occupation and long-term recovery.
Step 3: Planning outcomes and interventions
Outcomes should be specific, observable, realistic, relevant and time-bound. “Patient will improve” cannot be reliably evaluated. A stronger outcome is: “During this shift the patient will remain free from injury, disclose any increase in suicidal urge to staff and participate in a jointly written immediate safety plan when concentration permits.”
Plan with the patient, not merely for the patient. Record preferences, language, triggers, calming strategies, family participation, cultural considerations and what should happen during a crisis.
Step 4: Implementation
- Independent nursing actions: Therapeutic engagement, observation, environmental safety, sleep and nutrition support, health education and evaluation.
- Prescribed/dependent actions: Administration of medicines, investigations and treatments authorized by an appropriate prescriber.
- Collaborative actions: Psychological therapy, medical review, occupational rehabilitation, social support, family meetings and referral.
Step 5: Evaluation
Compare current findings with the outcome criteria: met, partially met or not met. Ask what changed, why, whether there were adverse effects and whether the formulation is still correct. Continue, modify, escalate or close the intervention accordingly. Evaluation begins the next assessment cycle.
Worked care plan: acute psychosis with command hallucinations
| Assessment/diagnosis | Outcome | Interventions with rationale | Evaluation |
|---|---|---|---|
| Risk for suicide related to command hallucinations, hopelessness and accessible pesticide. | Patient remains free from self-harm; means removed; staff know observation level; patient reports escalation promptly. | Place in safest observable area and institute prescribed observation; remove hazards with consent/lawful authority; ask directly about voices, intent, plan and means at each change; engage calmly and validate distress without agreeing with voices; urgent psychiatric review; involve chosen support person with consent; create safety plan as concentration improves. | No attempt/injury; urges and hallucinations reassessed; observation reduced only after documented multidisciplinary review. |
| Disturbed sensory perception evidenced by distressing voices and distraction. | Within 72 hours, patient identifies two coping responses and reports reduced distress or frequency. | Use brief clear communication; reduce excessive stimulation; help identify triggers; encourage reality-based activity; teach distraction/grounding; administer prescribed antipsychotic and monitor response/adverse effects. | Record voice frequency, content, distress, function and adverse effects—not simply “better.” |
| Self-care deficit evidenced by poor hygiene and refusal of meals. | Consumes agreed fluids/meals and completes graded hygiene with decreasing assistance. | Assess swallowing, oral health, delusional fear, depression and medical causes; offer sealed/preferred foods where appropriate; monitor intake/output and weight; break hygiene into small steps; preserve dignity and praise effort; escalate dehydration or prolonged refusal. | Quantify intake and assistance; review physical observations and laboratory findings when ordered. |
| Deficient knowledge/treatment-management difficulty. | Before discharge, patient and chosen carer explain medicine purpose, major warning signs, follow-up and relapse plan. | Teach in short sessions; use teach-back; discuss beliefs, cost and adverse effects; provide written plan; reconcile medicine supply and appointment; identify early warning signs and crisis contacts. | Patient demonstrates teach-back and a feasible plan rather than merely receiving information. |
Application to common priorities
Aggression
Identify triggers and early warning signs, remove bystanders, maintain an exit route, use one calm communicator and offer choices. Define the measurable goal as safety and reduction of arousal. Record what preceded the event, what helped, any restriction, monitoring and debriefing.
Food and fluid refusal
Determine whether the cause is psychosis, depression, catatonia, swallowing difficulty, nausea, cultural concern or deliberate protest. Measure intake and hydration, assess capacity and physical danger, involve the team early and avoid power struggles.
Insomnia
Assess mania, anxiety, withdrawal, pain, medicines and environment. Plan quiet routine, daytime activity, reduced evening stimulation and prescribed treatment. Evaluate actual sleep duration, daytime function and adverse effects.
Discharge nursing process
- Repeat mental state, physical health and risk assessment.
- Confirm housing, food, transport, medicine supply and follow-up feasibility.
- Provide a collaborative relapse and crisis plan with early warning signs.
- Reconcile every medicine and explain adverse-effect monitoring.
- Communicate the care plan to the receiving service; specify pending tests and responsibilities.
- Document patient and family understanding using teach-back.
Common documentation errors
- Using judgmental labels instead of observable facts.
- Copying identical care plans across days without evaluation.
- Listing interventions with no frequency, trigger or rationale.
- Recording “denies suicide” without intent, plan, means, history, protective factors and collateral information.
- Focusing on psychiatric symptoms while omitting physical observations and adverse effects.
Revision questions
- Explain every stage of the nursing process using a psychiatric example.
- Differentiate medical diagnosis, nursing diagnosis and risk formulation.
- Write measurable outcomes for suicide risk, insomnia and self-care deficit.
- Develop a care plan for a person with acute mania or severe depression.
- Explain how evaluation changes the next cycle of care.
