A nursing diagnosis is a clinical judgement about a patient's response (actual or potential) to health conditions or life processes that nurses are licensed and accountable to treat. Unlike a medical diagnosis, which names a disease or pathology, a nursing diagnosis names the patient's response to that disease or to a life situation. The standardised vocabulary of nursing diagnosis is maintained by NANDA International, whose current reference is Nursing Diagnoses: Definitions and Classification 2024-2026 (twelfth edition 2023, edited by T. Heather Herdman, Shigemi Kamitsuru, and Camila Takao Lopes). The taxonomy currently catalogues 267 approved diagnoses across 13 domains and 47 classes. EssayFount writing experts use this guide with pre-licensure students writing first care plans, RN-to-BSN students working through diagnostic-reasoning assignments, MSN students writing comprehensive case studies, and DNP students whose evidence-based-practice projects must use NANDA-I labels in their data architecture.
Where the standardised vocabulary came from: the 1973 First National Conference
The nursing diagnosis as a standardised label dates from the First National Conference on the Classification of Nursing Diagnoses, held at Saint Louis University in 1973 and convened by Marjory Gordon and Kristine Gebbie. The conference produced an initial list of approximately one hundred diagnostic labels and led to the founding of the North American Nursing Diagnosis Association in 1982. The organisation became NANDA International in 2002 to reflect the broader international community of users; the formal name today is NANDA International, Inc., and the abbreviation NANDA-I is the convention.
The terminology has gone through twelve editions. Each edition adds new diagnoses, retires diagnoses without sufficient empirical support, and revises definitions and defining characteristics. A paper that cites a label from an old edition without checking whether the label has been retired or revised is a paper a grader will catch. The current 2024-2026 edition is the only edition in active use; previous editions are historical.
Taxonomy II at a glance: 13 domains, 47 classes, 267 diagnoses
Taxonomy II, introduced in the 2003 edition and refined since, is the structural framework NANDA-I uses to organise the diagnoses. The taxonomy operates at three nested levels. At the top sit 13 domains, each naming a broad area of human functioning. Each domain holds one to several classes (47 in total), each naming a sub-area of functioning. Each class holds one to several individual diagnoses (267 in total), each naming a specific patient response.
The 13 domains are health promotion; nutrition; elimination and exchange; activity and rest; perception and cognition; self-perception; role relationship; sexuality; coping and stress tolerance; life principles; safety and protection; comfort; and growth and development. The next ten headings walk through the most clinically used diagnoses inside each domain, with one or two examples of the diagnosis statements students most often write in each.
Domain 1, Health promotion: deficient and readiness diagnoses
Health promotion holds diagnoses about the patient's awareness of well-being and the strategies they use to maintain or enhance it. Two of the most-used diagnoses in this domain are deficient diversional activity engagement, which appears in long-term-care and rehabilitation settings, and the readiness for enhanced health management diagnosis, which is one of the canonical health-promotion diagnoses in primary-prevention nursing. The readiness diagnoses begin with the phrase "readiness for enhanced" and use a one-part format because they describe a desire to improve a status rather than a present problem.
Domain 2, Nutrition: ingestion, digestion, absorption, metabolism, hydration
The nutrition domain holds five classes that follow the physiological sequence from ingestion to hydration. Imbalanced nutrition: less than body requirements is one of the most-written diagnoses in oncology and gastroenterology. Imbalanced nutrition: more than body requirements appears in chronic-disease and obesity-management contexts. Risk for unstable blood glucose level is a common diagnosis in diabetes care, and deficient fluid volume and excess fluid volume are core diagnoses in cardiac, renal, and post-operative care. The hydration class also holds the risk diagnosis for electrolyte imbalance, which appears in critical-care and post-surgical settings.
Domain 3, Elimination and exchange: urinary, gastrointestinal, integumentary, respiratory function
Elimination and exchange holds diagnoses about the secretion and excretion of waste products. Impaired urinary elimination, urinary retention, urinary incontinence (with several specified types: stress, urge, functional, overflow, reflex, total), constipation, perceived constipation, diarrhoea, and impaired bowel continence are the most-written diagnoses on the urinary and gastrointestinal sides. On the respiratory side, impaired gas exchange names a diagnosis whose etiology cuts across cardiac and pulmonary pathology and whose defining characteristics include abnormal arterial blood gases, hypoxia, and altered mental status.
Domain 4, Activity and rest: sleep, energy, response, self-care
The activity-and-rest domain holds five classes and contains some of the most-written nursing diagnoses across all settings. Activity intolerance, fatigue, impaired physical mobility, impaired walking, and impaired wheelchair mobility cover the activity and energy classes. Insomnia, sleep deprivation, and disturbed sleep pattern cover the sleep class. The self-care class is among the most-written in geriatric and rehabilitation nursing: bathing self-care deficit, dressing self-care deficit, feeding self-care deficit, and toileting self-care deficit each name a specific functional limitation. The cardiovascular and pulmonary responses class holds decreased cardiac output, ineffective breathing pattern, and ineffective airway clearance, three diagnoses that drive a substantial fraction of the work done in acute-care nursing.
Domain 5, Perception and cognition: attention, orientation, sensation, communication, knowledge, thinking
The perception-and-cognition domain spans the patient's sensory and intellectual functioning. The diagnoses most-written in this domain are deficient knowledge (about a specific topic, with the topic always named), readiness for enhanced knowledge, acute confusion, chronic confusion, impaired memory, and impaired verbal communication. The deficient-knowledge diagnosis is the most-used patient-education diagnosis in nursing care plans and is sometimes overused: a paper that names deficient knowledge as a primary diagnosis without naming what the patient does not know and without anchoring it to a specific defining characteristic in the data has not yet derived the diagnosis from cues.
Domain 6, Self-perception: self-concept, self-esteem, body image
The self-perception domain holds diagnoses about how the patient sees themselves. Disturbed personal identity, hopelessness, powerlessness, situational low self-esteem, chronic low self-esteem, and disturbed body image are the principal diagnoses. The body-image diagnoses are heavily used in oncology nursing (especially after mastectomy or amputation), in burn care, and in rehabilitation after spinal-cord injury. The self-esteem diagnoses are heavily used in psychiatric and mental-health nursing.
Domain 7, Role relationships: caregiver, family, role performance
The role-relationships domain holds diagnoses about how the patient functions in the network of relationships they belong to. Caregiver role strain and risk for caregiver role strain are heavily used in home-health, hospice, and chronic-illness contexts. Impaired parenting, risk for impaired parent-infant attachment, and dysfunctional family processes are heavily used in maternal-child nursing. Ineffective role performance and ineffective relationship cover the broader role-functioning class.
Domain 8, Sexuality: sexual identity, function, reproduction
The sexuality domain holds three classes covering sexual identity, sexual function, and reproduction. Sexual dysfunction, ineffective sexuality pattern, and ineffective childbearing process are the principal diagnoses. The childbearing-process diagnoses are heavily used in maternal-child nursing and have been extensively revised in recent NANDA-I editions to reflect changes in obstetric care.
Domain 9, Coping and stress tolerance: post-trauma, coping, neurobehavioural stress
Coping and stress tolerance holds three classes that cover the patient's response to stressors. Post-trauma syndrome, rape-trauma syndrome, and risk for post-trauma syndrome cover the post-trauma response class. Ineffective coping, defensive coping, ineffective denial, ineffective community coping, compromised family coping, and disabled family coping cover the coping-response class. Anxiety and death anxiety are also in this domain, in the neurobehavioural-stress class. Anxiety is among the most-written diagnoses in psychiatric, oncology, palliative, and pre-operative settings.
Domain 10, Life principles: values, beliefs, value-belief-action congruence
The life-principles domain holds the spiritual and ethical-decision diagnoses. Spiritual distress and risk for spiritual distress are heavily used in palliative, oncology, and end-of-life care. Decisional conflict (about a specific health decision, with the decision always named) is the principal diagnosis in the value-belief-action class and appears most often in oncology and palliative-care contexts where treatment choices carry strong values dimensions.
Domain 11, Safety and protection: infection, physical injury, violence, environmental hazards, defensive processes, thermoregulation
Safety and protection is one of the largest domains by diagnosis count. Risk for infection is the most-written risk diagnosis in nursing, appearing across nearly every clinical setting. Risk for falls, risk for injury, risk for aspiration, impaired skin integrity, risk for pressure ulcer, risk for impaired skin integrity, ineffective airway clearance, and ineffective protection are heavily used. The violence class holds risk for self-directed violence, risk for other-directed violence, and risk for suicide, all heavily used in psychiatric and mental-health nursing. The thermoregulation class holds hypothermia, hyperthermia, and ineffective thermoregulation.
Domain 12, Comfort: physical, environmental, social
The comfort domain holds the pain and the broader-comfort diagnoses. Acute pain, chronic pain, chronic pain syndrome, and labour pain are the principal pain diagnoses. Impaired comfort and readiness for enhanced comfort cover the broader-comfort class. The acute-pain diagnosis is among the most-written diagnoses across acute-care nursing, and the labour-pain diagnosis is the standard pain diagnosis in maternal-child nursing.
Domain 13, Growth and development
The smallest domain, growth and development holds risk for delayed development and delayed growth and development. Both diagnoses appear most often in paediatric and developmental-disabilities nursing, and the delayed-development diagnosis requires the nurse to specify the developmental milestone that the child is not meeting.
Four categories of nursing diagnosis
NANDA-I distinguishes four categories of nursing diagnosis, and each category has a different statement format and a different evidentiary requirement. Knowing which category a chosen diagnosis belongs to is what determines whether a one-part, two-part, or three-part statement is appropriate.
A problem-focused diagnosis (sometimes called an actual diagnosis) names a clinical judgement about an undesirable human response that is currently present. It uses the three-part PES format, in which P names the NANDA-I label, E names the related etiology, and S names the signs and symptoms (defining characteristics) drawn from the assessment data. Acute pain related to surgical tissue trauma as evidenced by patient-reported pain six out of ten and guarded movement is a problem-focused diagnosis.
A risk diagnosis names a clinical judgement about a vulnerability to develop an undesirable response. It uses a two-part format, with P naming the NANDA-I label and E naming the risk factors. Defining characteristics are not included because the response has not yet occurred. Risk for falls related to recent hip arthroplasty, post-operative weakness, and patient-reported fear of pain is a risk diagnosis.
A health-promotion diagnosis names a motivation or desire to enhance a behaviour or status. It uses a one-part format consisting of the NANDA-I label alone, beginning with the phrase "readiness for enhanced." Readiness for enhanced knowledge or readiness for enhanced spiritual well-being are health-promotion diagnoses.
A syndrome diagnosis names a cluster of diagnoses that occur together and are best treated as a group. Post-trauma syndrome, chronic pain syndrome, and risk-prone health behaviour are syndrome diagnoses. Syndrome diagnoses use a one-part format.
The PES format walked through
The PES statement is the working artefact of the diagnosis phase. Each part has a different function and a different evidentiary basis, and writing the parts in the wrong order or filling them with the wrong content is the most documented error in undergraduate care plans.
The P (problem) is the NANDA-I diagnostic label, taken verbatim from the current twelfth edition. Substituting a paraphrase or an institutional variant breaks the standardised vocabulary; the chart entry must use the exact label.
The E (etiology, written after the phrase "related to") names the cause or the contributing factors that the related-factors list in NANDA-I authorises for the chosen diagnosis. The etiology cannot be a medical diagnosis (pneumonia or congestive heart failure are diseases, not nursing-actionable etiologies); it cannot be a NANDA-I label (using one diagnosis as the etiology of another is circular); it cannot be a treatment or piece of equipment.
The S (signs and symptoms, written after the phrase "as evidenced by") names the defining characteristics from the patient's assessment data that match the defining-characteristics list NANDA-I provides for the chosen diagnosis. If the data does not contain enough defining characteristics to justify the diagnosis, the statement should be a risk diagnosis instead, with risk factors in place of defining characteristics.
From cues to a diagnosis: a worked derivation
The diagnostic-reasoning move that produces a NANDA-I statement from raw assessment data is a four-step process. First, the nurse clusters related cues from the assessment data. Second, the nurse identifies the pattern those cues suggest. Third, the nurse compares the pattern against the defining-characteristics lists of candidate NANDA-I diagnoses. Fourth, the nurse selects the diagnosis whose defining characteristics best match the cluster and writes the PES statement.
For a patient with the cues productive cough, thick green sputum, dyspnoea on exertion at one block of walking, oxygen saturation 89 percent on room air, lung sounds with diffuse expiratory wheezes, and patient using accessory muscles, the cluster suggests a respiratory-elimination problem. The pattern matches the defining characteristics for ineffective airway clearance (productive cough, abnormal lung sounds, dyspnoea, ineffective cough). The PES statement reads: ineffective airway clearance related to retained secretions and bronchoconstriction as evidenced by productive cough with thick green sputum, dyspnoea on exertion, and diffuse expiratory wheezes.
For the same patient, the additional cues smoking history twenty pack-years with current half-pack-per-day use, home oxygen prescribed but not consistently worn, and incorrect inhaler technique cluster differently and suggest a different domain (health promotion or knowledge). The pattern matches the defining characteristics for ineffective health management (failure to take action to reduce risk factors, ineffective choices in daily living for meeting health goals). A second PES statement reads: ineffective health management related to gaps in inhaler technique and oxygen-use adherence as evidenced by incorrect inhaler technique on observation and current tobacco use despite home-oxygen prescription. The patient now has two diagnoses, each derived from a different cue cluster.
What is not a nursing diagnosis
Five things look like a nursing diagnosis but are not, and each appears as a substitution error in undergraduate care plans. Naming them keeps the diagnostic statement clean.
- A medical diagnosis. Pneumonia, congestive heart failure, type two diabetes, and acute myocardial infarction are diseases, not patient responses. They belong in the medical-diagnosis field of the chart, not the nursing-diagnosis field.
- A laboratory or imaging value. Hyponatraemia, leukocytosis, and ST-segment elevation are findings, not patient responses. The corresponding nursing diagnoses might be deficient fluid volume, risk for infection, or decreased cardiac output, derived from the patient's response to the underlying condition.
- A piece of equipment or a treatment. "Patient on a ventilator" or "needs a tracheostomy" are equipment or interventions, not patient responses. The corresponding nursing diagnosis might be impaired spontaneous ventilation or ineffective airway clearance.
- A nursing intervention. "Needs ambulation" or "requires turning every two hours" are interventions, not patient responses. The corresponding nursing diagnosis might be impaired physical mobility or risk for impaired skin integrity.
- A patient request or wish. "Wants to go home" is a patient preference, not a NANDA-I diagnosis.
Diagnoses students most often misuse
Three diagnoses appear in undergraduate care plans more often than the data justifies. Knowing the misuse pattern is what stops the substitution.
The first is deficient knowledge. The diagnosis requires the student to specify what the patient does not know (the topic of the deficit) and to anchor the deficit in a defining characteristic in the data (an inaccurate response on patient teach-back, an explicit verbalisation of misunderstanding). A diagnosis that names deficient knowledge without specifying the topic and without an anchoring cue is a placeholder, not a derived diagnosis.
The second is anxiety. Anxiety is a NANDA-I diagnosis with specific defining characteristics (apprehension, increased heart rate, restlessness, verbalisation of worry). A patient who is fearful of an upcoming surgical procedure has anxiety only if the data shows the defining characteristics; a quiet patient who is "probably anxious about surgery" by the student's inference does not meet the diagnostic threshold. Fear is the alternative diagnosis when the threat is identifiable; anxiety applies when the threat is not.
The third is impaired skin integrity. Impaired skin integrity is the actual problem-focused diagnosis (the skin barrier is currently compromised). Risk for impaired skin integrity is the risk diagnosis (the patient is vulnerable but the skin is currently intact). Confusing the two and writing impaired skin integrity for a patient whose skin is intact converts a risk diagnosis into an actual diagnosis without the defining-characteristic data, which is the failure mode graders catch most often in fundamentals-level papers.
Reader questions about nursing diagnosis
What are examples of nursing diagnoses?
Common NANDA-I nursing diagnoses students see most often include Acute Pain (00132), Risk for Falls (00155), Impaired Skin Integrity (00046), Ineffective Airway Clearance (00031), Anxiety (00146), and Imbalanced Nutrition: Less Than Body Requirements (00002). Each is a labelled human-response judgement, not a medical diagnosis. The full PES format puts the diagnosis label first, then the related factor, then the defining characteristics, for example 'Acute Pain related to surgical incision as evidenced by patient rating of 8 out of 10 on the numeric pain scale and guarded movement.'
What are the 4 types of NANDA?
NANDA-I sorts every diagnosis into one of four categories: problem-focused, risk, health-promotion, and syndrome. A problem-focused diagnosis names a current human response (Acute Pain). A risk diagnosis names a vulnerability (Risk for Infection). A health-promotion diagnosis names a readiness to improve a behaviour (Readiness for Enhanced Nutrition). A syndrome diagnosis names a cluster of co-occurring diagnoses that move together (Post-Trauma Syndrome). Selecting the correct category is the first taxonomic decision in care planning and shapes how the PES statement is written.
What are the 21 nursing problem categories?
The 21 nursing problem categories are Faye Abdellah's 1960 framework, not a NANDA-I list. Abdellah grouped patient needs into 21 problem areas covering hygiene, safety, body mechanics, oxygenation, hydration, sleep, activity, elimination, nutrition, sensory function, fluid and electrolyte balance, infection control, communication, growth and development, emotional needs, social interaction, spiritual needs, awareness of self, recognition of community resources, and acceptance of optimum health goals. The framework predates NANDA-I by more than a decade and is taught as nursing-history scholarship rather than as a current diagnostic taxonomy.
What are the 5 points of nursing diagnosis?
The five components of a complete NANDA-I nursing diagnosis are the diagnostic label, the definition, the defining characteristics, the related factors, and the at-risk population. The label and definition are fixed by NANDA-I; defining characteristics are the cues that justify naming the diagnosis in this patient; related factors are the etiology that the nursing care will target; the at-risk population names who is more likely to develop the response. The 2024-2026 edition adds associated conditions as a sixth element for some diagnoses where comorbid medical conditions are clinically inseparable.
What are three nursing diagnoses?
A common student exercise is to list three diagnoses for one patient ranked by Maslow's hierarchy. For a post-operative patient with controlled pain, the three are usually Acute Pain (a physiological priority), Risk for Infection (a safety vulnerability), and Anxiety (a psychological response). The first names an immediate physiological response, the second flags a vulnerability the surgical wound creates, and the third addresses the patient's emotional state. Each is documented as a complete PES or two-part risk statement, never as a single label, and the three are prioritised in care-plan order.
What are some common diagnoses?
The diagnoses most frequently used on undergraduate care plans are Acute Pain, Risk for Falls, Impaired Skin Integrity, Ineffective Breathing Pattern, Activity Intolerance, Constipation, Risk for Infection, Anxiety, Deficient Knowledge, and Imbalanced Nutrition. They appear most often because they map onto the conditions students see in medical-surgical, paediatric, and post-operative rotations. Each has a published label, definition, defining-characteristics list, and etiology list inside the NANDA-I 2024-2026 taxonomy that students can copy into a PES statement and adapt to the specific patient.
