The nursing process

In short

The nursing process is the organised, patient-centred, problem-solving method a nurse uses to deliver care — a cycle of Assessment, Diagnosis, Planning, Implementation and Evaluation (ADPIE). It converts data about a patient into a written, measurable plan, carries it out and checks whether it worked, so care is deliberate rather than routine. It is the single most examined concept in Fundamentals of Nursing (B.Sc Nursing I year, Indian Nursing Council curriculum) and reappears in every clinical subject, because every care plan, case study and case presentation in the course is built on it. In placement tests and interviews for AIIMS, PGIMER, NIMHANS, JIPMER, state NHM posts, ESIC, Railways, Apollo, Fortis, Manipal, Medanta and Max, candidates are asked to name the steps, give a diagnosis in correct format, and show how documentation and NABH quality audits depend on it.

Explained

Definition, characteristics and theoretical basis

• Definition: a systematic, rational, cyclic method of planning and providing individualised nursing care, based on scientific knowledge and critical thinking.
• History: the term was introduced by Lydia Hall (1955); Orlando, Wiedenbach, Yura and Walsh developed it; the fifth step (diagnosis) was added in the 1970s, making it five phases instead of four.
• Characteristics: systematic, dynamic (phases overlap and repeat), interpersonal, goal-directed, universally applicable, patient-centred, outcome-oriented, evidence-based.
• Theoretical support: Maslow's hierarchy (physiological needs before safety, love, esteem, self-actualisation) sets priority; Henderson's 14 basic needs and Orem's self-care deficit theory guide what to assess; Roy's adaptation model frames responses to stressors.
• Relation to other methods: it mirrors the scientific method (problem → data → hypothesis → plan → test → conclusion) and the medical process (history, examination, diagnosis, treatment, prognosis), but addresses *responses* to illness, not the disease itself.
• Legal and professional base in India: the Indian Nursing Council Act, 1947 empowers INC to prescribe the curriculum in which the nursing process is core; state nursing council registration is required to practise; nursing records are legal documents admissible in court, and the Consumer Protection Act, 2019 covers healthcare services, so an undocumented assessment is treated as one not done.

Phase 1 — Assessment

• Meaning: systematic, continuous collection, organisation, validation and documentation of data about the patient's health status.
• Types of assessment: *initial/admission* (within a set time of admission, often 24 hours as per hospital policy); *focused* (one problem, e.g. chest pain); *emergency* (ABC — airway, breathing, circulation); *time-lapsed/ongoing* (reassessment to compare with baseline).
• Types of data: subjective (symptoms — what the patient says: "I feel giddy"; covert) and objective (signs — measurable/observable: BP 90/60 mmHg, pallor; overt).
• Sources: *primary* — the patient; *secondary* — family, old records, other nurses and doctors, diagnostic reports, literature.
• Methods: interview (open-ended and closed questions), observation (inspection), physical examination (inspection, palpation, percussion, auscultation), measurement (vital signs, height, weight, intake-output), review of records and investigations.
• Organising frameworks: head-to-toe, body systems, Maslow's needs, Gordon's 11 functional health patterns, Henderson's 14 needs, or the hospital's own nursing-assessment form.
• Validation: cross-check doubtful data (repeat a BP with a correct cuff, compare reported "fever" with a measured temperature) to avoid diagnosing on faulty cues.
• Clustering: group related cues — dyspnoea + crackles + SpO₂ 88% + cough with sputum form one cluster pointing to ineffective airway clearance.

Phase 2 — Nursing diagnosis

• Definition (NANDA-International): a clinical judgement about an individual, family, group or community response to actual or potential health problems and life processes, which the nurse is licensed and competent to treat.
• Steps: analyse and interpret data → identify the problem → compare with defining characteristics → write the statement → prioritise.
• Types:
  1. Actual — a problem present now, with signs and symptoms.
  2. Risk (potential) — risk factors present but no signs yet: "Risk for falls related to age, unsteady gait and sedative use" (risk diagnoses have two parts — the label plus risk factors, with no "as evidenced by", as there are no symptoms to cite).
  3. Health-promotion/wellness — a desire to raise well-being: "Readiness for enhanced nutrition".
  4. Syndrome — a cluster that occurs together, e.g. "Disuse syndrome".
  5. Possible — more data needed before confirming.
• Format — PES / three-part statement: Problem (NANDA label) + Etiology ("related to", the cause the nurse can act on) + Signs and symptoms ("as evidenced by"). Example: *Impaired skin integrity related to prolonged immobility as evidenced by a 3 cm stage-2 sacral ulcer.*
• Nursing vs medical vs collaborative: medical diagnosis names the disease (pneumonia) and the doctor treats it; nursing diagnosis names the response (ineffective airway clearance) and the nurse treats it independently; collaborative problems need both (potential complication: hypoglycaemia in insulin therapy).
• Rules for writing: state the patient's response, not the nurse's problem or activity; do not use a medical diagnosis as the problem; use "related to" (not "due to", which implies legal causation); avoid value judgements and legally risky wording ("ulcer related to poor nursing care"); one problem per statement; make the etiology something nursing can modify.
• Prioritisation: by Maslow (airway and circulation first), by urgency (high / intermediate / low priority), and with the patient's own perception of what matters.

Phase 3 — Planning

• Purpose: decide what to achieve and how, and write it down so every shift gives the same care.
• Kinds of planning: *initial* (by the admitting nurse), *ongoing* (updated every shift as data change), *discharge* (teaching, follow-up, home care — begins at admission, not on discharge day).
• Steps: set priorities → write expected outcomes/goals → select nursing interventions with rationale → write the nursing care plan.
• Goals / expected outcomes must be SMART: Specific, Measurable, Achievable, Relevant, Time-bound. Components: subject (patient), verb, condition, criterion of performance, time frame — "The patient will walk 20 metres in the corridor with a walker without giddiness by the 4th post-operative day."
• Short-term goals are achievable in hours to days (acute care); long-term goals take weeks to months (rehabilitation, chronic disease, community care).
• Types of intervention: independent (nurse-initiated: positioning, back care, deep-breathing exercises, health teaching), dependent (physician-ordered: administer drugs, IV fluids), interdependent/collaborative (with dietitian, physiotherapist, medical social worker).
• Standardised languages: NANDA-I (diagnoses), NIC (Nursing Interventions Classification) and NOC (Nursing Outcomes Classification) — the NNN linkage; examined as definitions in theory papers.
• Care plan formats: traditional three/four-column (diagnosis, goal, intervention, rationale, evaluation), standardised care plans, protocols, clinical pathways/care maps, and concept maps. Most Indian teaching hospitals use a printed nursing care plan sheet plus a Kardex for quick reference.

Phase 4 — Implementation

• Meaning: carrying out the planned interventions and recording them.
• Steps: reassess the patient (the plan may no longer fit), determine the nurse's need for help, implement the orders, supervise delegated care, document care and the patient's response.
• Requirements: cognitive (knowing the rationale), interpersonal (communication, support, patient teaching) and psychomotor (technical skill) competence.
• Delegation: right task, right circumstance, right person, right communication, right supervision — the registered nurse remains accountable for care delegated to a nursing assistant or student.
• Documentation: record what was done, when, by whom and with what result, using accepted formats — narrative, SOAP/SOAPIE (Subjective, Objective, Assessment, Plan, Intervention, Evaluation), PIE, focus charting (DAR: Data, Action, Response), charting by exception, and electronic health records.
• Rules: chart after the act, never before; no blank lines; correct an error by a single line through it with initials, never by erasing or whitening; sign with name and designation; keep to the facts; "not charted = not done".

Phase 5 — Evaluation

• Meaning: judging the extent to which goals were met, by comparing the patient's current status with the stated outcome criteria.
• Steps: collect data about the outcome → compare with the criterion → draw a conclusion (goal met / partially met / not met) → relate care to the outcome → modify, continue or terminate the plan.
• Types: *structure* (staff, equipment, environment), *process* (how care was given), *outcome* (what happened to the patient) — Donabedian's model, the basis of nursing audit.
• If a goal is not met: check each phase — was data incomplete, the diagnosis wrong, the goal unrealistic, the intervention inappropriate, or was it not carried out? Then reassess; this closes the cycle.
• Quality assurance in India: nursing audits, concurrent and retrospective record review, incident reporting, and NABH accreditation standards (nursing assessment, reassessment, care planning and documentation are directly scored); fall rate, pressure-ulcer rate, medication-error rate and CAUTI rate are standard nursing-sensitive indicators.

Advantages, limitations and critical thinking

• Advantages: individualised and continuous care, clear priorities, avoids duplication and omission, improves communication and handover (ISBAR/SBAR), gives legal protection, supports research, teaching and costing, and increases patient participation and satisfaction.
• Limitations: time-consuming paperwork; poor nurse-patient ratios in Indian government hospitals make full care plans difficult; needs training in NANDA language; care plans can become copied formats rather than individual thinking; evaluation is often skipped.
• Critical thinking components used throughout: interpretation, analysis, inference, evaluation, explanation and self-regulation; attitudes of independence, fairness, humility and curiosity.

Key points

• Nursing process - systematic, cyclic, patient-centred problem-solving method of giving nursing care.
• ADPIE - Assessment, Diagnosis, Planning, Implementation, Evaluation; five phases, overlapping, not strictly linear.
• Lydia Hall (1955) - introduced the term; the diagnosis phase was added in the 1970s, making five steps.
• Subjective data - what the patient reports (symptoms); objective data - what is measured or observed (signs).
• Primary source - the patient; everything and everyone else is a secondary source.
• Assessment types - initial, focused, emergency, time-lapsed/ongoing.
• Nursing diagnosis - judgement about a patient's *response*, treatable by the nurse; a medical diagnosis names the disease.
• PES format - Problem "related to" Etiology "as evidenced by" Signs/symptoms; risk diagnoses use only two parts.
• Five diagnosis types - actual, risk, health-promotion, syndrome, possible.
• Prioritisation - Maslow's hierarchy plus urgency and the patient's own priority; life-threatening problems first.
• SMART goals - Specific, Measurable, Achievable, Relevant, Time-bound, with subject, verb, criterion and time frame.
• Intervention types - independent (nurse-initiated), dependent (physician-ordered), interdependent (collaborative).
• NANDA-I, NIC, NOC - standardised languages for diagnoses, interventions and outcomes.
• Implementation - reassess, seek help, act, delegate with accountability, document response.
• Evaluation verdicts - goal met, partially met, not met; then modify, continue or terminate the plan.
• Donabedian - structure, process and outcome evaluation; the framework for nursing audit.
• "Not charted = not done" - records are legal documents; the Consumer Protection Act, 2019 covers health services.
• INC - constituted under the Indian Nursing Council Act, 1947; prescribes the curriculum and standards for nursing education in India.

Formulas and examples

Example 1 — Full care plan for a post-operative patient A 48-year-old man, day 1 after open cholecystectomy. Data: "Pain is severe when I move" (subjective); pain score 8/10, respirations 26/min and shallow, refuses to turn, BP 140/90 mmHg, pulse 104/min, splinting the right upper abdomen (objective).

• Cluster → pain with guarding and shallow breathing.
• Diagnosis: Acute pain related to surgical incision and tissue trauma as evidenced by a pain score of 8/10, guarding, pulse 104/min and shallow respirations of 26/min.
• Goal (SMART): the patient's reported pain will fall to 3/10 or less within 1 hour of analgesia and he will turn and deep-breathe every 2 hours by the end of the shift.
• Interventions: assess pain hourly on a 0-10 scale (independent); administer prescribed analgesic and record effect after 30-60 minutes (dependent); support the incision with a pillow while turning and coughing (independent); position semi-Fowler's, provide a quiet environment, teach splinting and relaxation (independent).
• Evaluation after 1 hour: pain 2/10, respirations 18/min, patient turned with help — goal met; continue the plan with the analgesic prescription reviewed before mobilisation.

Example 2 — Converting raw data into two correctly written diagnoses A 70-year-old woman admitted with a fractured neck of femur, on traction, incontinent of urine, Braden score 14, albumin low, skin intact.

• Diagnosis A (risk, two parts): Risk for impaired skin integrity related to immobility, urinary incontinence and poor nutritional status (Braden 14).
• Diagnosis B (actual, three parts): Impaired physical mobility related to skeletal traction and pain as evidenced by inability to turn independently and a Barthel/ADL dependence for bathing and toileting.
• Note: "Fracture neck of femur" cannot be the problem — it is the medical diagnosis; it belongs in the etiology.

Example 3 — Intake-output and evaluation arithmetic A patient on IV fluids over 24 hours: oral 600 mL, IV 2,000 mL, IV antibiotic diluents 200 mL → intake = 600 + 2,000 + 200 = 2,800 mL. Output: urine 1,500 mL, drain 250 mL, vomitus 150 mL, insensible loss taken as 500 mL → output = 1,500 + 250 + 150 + 500 = 2,400 mL. Balance = 2,800 − 2,400 = +400 mL.

• Urine 1,500 mL in 24 h for a 60 kg adult = 1,500 / (60 × 24) ≈ 1.04 mL/kg/h — adequate.
• Evaluation: the goal "balance within ±500 mL in 24 h" is met; continue monitoring, no change in plan.

Example 4 — Audit calculation on a ward A 30-bed ward: 112 nursing goals were set in a month, 84 fully met, 18 partially met, 10 not met. Patient-days = 30 beds × 30 days × 0.9 occupancy = 810 patient-days; 2 falls occurred.

• Goal attainment = 84/112 × 100 = 75%.
• Fall rate = 2/810 × 1,000 = 2.47 falls per 1,000 patient-days.
• Interpretation: 25% of goals unmet points to the evaluation phase — re-examine whether goals were realistic and interventions actually carried out.

Example 5 — BMI as an assessment cue A 54 kg woman of height 1.62 m: BMI = 54 / (1.62²) = 54 / 2.6244 = 20.6 — normal on ICMR Asian cut-offs, so "Imbalanced nutrition: less than body requirements" is not supported by BMI alone; further cues (haemoglobin, dietary recall, weight loss history) are needed before diagnosing.

Where it is used

• Teaching and corporate hospitals: nursing assessment forms, care plans, Kardex and SOAPIE/DAR notes at AIIMS, PGIMER, CMC Vellore, Apollo, Fortis, Manipal, Max and Medanta; NABH surveyors score reassessment and care-plan documentation directly.
• Government and community services: ANM/LHV and staff-nurse work under NHM — ante-natal assessment and risk screening, ASHA-linked home visits, immunisation follow-up, TB and NCD screening under Ayushman Bharat Health and Wellness Centres, where the same ADPIE logic drives the family health record.
• Critical care and emergency: emergency assessment (ABCDE), hourly reassessment charts, ICU flow sheets, early-warning scores; triage in casualty is prioritisation of diagnoses in practice.
• Job roles: staff nurse, ICU/OT/dialysis nurse, nurse educator (teaches care-plan writing), nursing supervisor (audits plans), infection-control nurse, quality/NABH coordinator, clinical research coordinator, and nurses recruited for Gulf, UK NMC and US NCLEX routes, where ADPIE and NANDA formats are tested explicitly.
• Examinations: B.Sc Nursing Fundamentals theory and clinical practicals (care plan and case presentation are marked items), INC/state nursing-officer recruitment papers (AIIMS NORCET, ESIC, Railway, state PSC), and nursing entrance tests for M.Sc.
• Records and law: nursing notes used in medico-legal cases, insurance claims and consumer-court matters; audit data feed hospital quality dashboards.

Interview questions

• Q: What are the steps of the nursing process? A: Assessment, Diagnosis, Planning, Implementation and Evaluation (ADPIE) — a cyclic process in which evaluation feeds back into reassessment.
• Q: How does a nursing diagnosis differ from a medical diagnosis? A: A nursing diagnosis describes the patient's response to a health problem and is treated independently by the nurse; a medical diagnosis names the disease and is treated by the physician.
• Q: Write a nursing diagnosis for a patient with pneumonia. A: Ineffective airway clearance related to retained thick secretions as evidenced by productive cough, crackles on auscultation and SpO₂ of 88% on room air.
• Q: Why does a risk diagnosis have only two parts? A: Because the problem has not yet occurred, so there are no signs and symptoms to state — only the problem label and the risk factors.
• Q: How do you prioritise when a patient has several problems? A: Life-threatening problems first using Maslow's hierarchy — airway, breathing, circulation — then safety, then psychosocial needs, while respecting what the patient feels is most urgent.
• Q: What makes a goal measurable? A: It states an observable behaviour with a criterion and a time frame, for example "will walk 20 metres with a walker by the fourth post-operative day", so any nurse can judge it as met or not met.
• Q: Difference between subjective and objective data, with one example each? A: Subjective is what the patient reports, such as nausea; objective is what is measured or observed, such as vomitus of 150 mL or a pulse of 110/min.
• Q: What do you do when a goal is not met? A: Reassess the patient and review every phase — data completeness, correctness of the diagnosis, realism of the goal, suitability of the interventions and whether they were actually carried out — then revise the plan.
• Q: What are independent, dependent and interdependent interventions? A: Independent are nurse-initiated like positioning and health teaching; dependent are carried out on a physician's order like giving a drug; interdependent are collaborative with the dietitian, physiotherapist or other team members.
• Q: Why is documentation part of the nursing process and not extra work? A: It is the evidence of assessment, care and response, ensures continuity across shifts, and is a legal record — care that is not charted is treated as care not given.
• Q: What is NANDA, NIC and NOC? A: NANDA-International provides standardised nursing diagnosis labels, NIC classifies nursing interventions and NOC classifies patient outcomes; together they let care be recorded, compared and researched.
• Q: How does the nursing process support NABH accreditation? A: NABH requires initial assessment, documented reassessment, a care plan with goals and evidence of implementation and evaluation — exactly the five phases, auditable in the patient record.
• Q: Can the phases overlap? A: Yes — assessment continues during implementation, and evaluation may reveal new data that changes the diagnosis, which is why the process is described as dynamic and cyclic.

Common mistakes

• Writing the medical diagnosis or an investigation result as the nursing problem ("Diabetes mellitus related to…") instead of the patient's response.
• Writing the nurse's activity as the goal ("to give back care every 2 hours") — goals must describe patient behaviour, not nursing action.
• Giving vague goals with no criterion or time frame ("patient will feel better", "pain will reduce").
• Adding "as evidenced by" signs to a *risk* diagnosis, or omitting the etiology from an actual one.
• Using "due to" or blame-implying wording ("pressure sore related to neglect by staff") — legally risky and not an etiology the nurse can modify.
• Mixing up subjective and objective data in the assessment column, and forgetting to validate doubtful cues before diagnosing.
• Skipping evaluation, or recording "goal met" without the data (no repeat pain score, no output figure) to support it.
• Charting before the care is given, erasing errors, or leaving blank lines and unsigned entries in the nurses' record.
