Nursing Diagnosis Guide 2026: NANDA Diagnoses, Care Plans, and How to Write Them Correctly

Nursing diagnosis is how nursing defines its unique clinical contribution. Medical diagnoses label disease: "hypertension," "myocardial infarction," "pneumonia." Nursing diagnoses label the human response to those diseases and the problems nursing can actually address and treat within nursing scope. A patient with pneumonia has a medical diagnosis. The same patient also has "Impaired Gas Exchange," "Ineffective Airway Clearance," and "Activity Intolerance" — nursing diagnoses that define what nurses will specifically assess, intervene for, and evaluate. These are two different but complementary clinical frameworks, not competing ones.

NANDA (formerly the North American Nursing Diagnosis Association, now NANDA International) is the professional organization that develops, standardizes, and publishes the official taxonomy of nursing diagnoses. NANDA diagnoses are used in nursing education, electronic health record care plan documentation, and standardized nursing language systems like NIC (Nursing Interventions Classification) and NOC (Nursing Outcomes Classification).

Types of NANDA Nursing Diagnoses

Type	Definition	Example
Problem-focused (Actual)	A clinical judgment about an undesirable human response that currently exists	Impaired Gas Exchange, Acute Pain, Deficient Fluid Volume
Risk	A clinical judgment about vulnerability to an undesirable response — the problem does not yet exist	Risk for Aspiration, Risk for Pressure Injury, Risk for Falls
Health Promotion	A clinical judgment about motivation and desire to increase well-being and actualize health potential	Readiness for Enhanced Nutrition, Readiness for Enhanced Self-Management
Syndrome	A cluster of actual or risk diagnoses that occur together and are best addressed together	Frail Elderly Syndrome, Chronic Pain Syndrome

The Three-Part Nursing Diagnosis Statement (PES Format)

Actual (problem-focused) nursing diagnoses are written in a three-part format using the PES structure:

P — Problem: The NANDA nursing diagnosis label. This is standardized language — you use the official NANDA diagnosis name, not a paraphrase. Example: "Impaired Gas Exchange"

E — Etiology (Related to): The causative or contributing factor that nursing interventions will address. Written as "related to..." This is the factor nurses can actually influence. Example: "related to alveolar-capillary membrane changes secondary to pneumonia"

S — Signs and Symptoms (As evidenced by): The objective and subjective data that support this diagnosis — the evidence that the problem exists. Example: "as evidenced by SpO2 88% on room air, respiratory rate 28, patient reporting dyspnea"

Combined: Impaired Gas Exchange related to alveolar-capillary membrane changes secondary to pneumonia as evidenced by SpO2 88% on room air, respiratory rate 28, and patient-reported dyspnea

Risk diagnoses use only two parts (P and E — no signs and symptoms because the problem hasn't happened yet): Risk for Aspiration related to decreased level of consciousness and absent gag reflex

Most Common NANDA Nursing Diagnoses in Clinical Practice

Nursing Diagnosis	Commonly Related To	Common in Setting
Acute Pain	Surgical incision, trauma, disease process	Med-surg, PACU, post-operative care
Impaired Gas Exchange	Pneumonia, ARDS, heart failure, COPD exacerbation	ICU, pulmonary units, med-surg
Ineffective Airway Clearance	Excessive mucus secretions, weak cough, decreased consciousness	ICU, post-operative, pneumonia patients
Deficient Fluid Volume	Vomiting, diarrhea, hemorrhage, diaphoresis, inadequate intake	All acute care settings
Excess Fluid Volume	Heart failure, renal failure, aggressive IV fluid therapy	ICU, cardiac units, med-surg
Risk for Falls	Altered gait, cognitive impairment, medications (antihypertensives, sedatives), weakness	All inpatient settings; universal fall risk assessment required
Risk for Infection	Surgical incision, invasive lines, immunosuppression, altered skin integrity	All acute care settings; particularly ICU and post-operative
Impaired Physical Mobility	Post-operative pain limiting movement, neurological impairment, orthopedic injury	Ortho, neuro, post-operative, ICU
Anxiety	Unfamiliar healthcare environment, new diagnosis, procedure anticipation	All settings; particularly pre-op, oncology, ICU family-facing care
Deficient Knowledge	Lack of prior exposure to diagnosis, medication, or procedure; language barrier; low health literacy	All settings; discharge planning emphasis
Impaired Skin Integrity / Risk for Pressure Injury	Immobility, incontinence, poor nutrition, peripheral vascular disease	ICU, long-term care, any immobilized patient
Ineffective Tissue Perfusion	Reduced cardiac output, arterial occlusion, shock states, vasospasm	ICU, cardiac, vascular patients

Medical Diagnosis vs. Nursing Diagnosis: The Critical Distinction

The most common error nursing students make is writing a medical diagnosis as a nursing diagnosis. "Congestive Heart Failure" is a medical diagnosis — it names the disease. Nurses cannot independently diagnose congestive heart failure. Nurses can diagnose and address the human responses to congestive heart failure: "Decreased Cardiac Output," "Excess Fluid Volume," "Activity Intolerance," "Impaired Gas Exchange."

Similarly, "Hypotension" is a sign, not a nursing diagnosis. The nursing diagnosis might be "Deficient Fluid Volume" (if hypotension is from volume depletion) or "Decreased Cardiac Output" (if from pump failure). The nursing diagnosis names the underlying problem that nursing can address — not the symptom the nurse observes.

NANDA vs. clinical nursing diagnoses: In real clinical practice, many nurses and health systems use simplified nursing diagnostic statements or clinical problem lists rather than formal NANDA taxonomy — particularly in electronic health records that use proprietary or simplified diagnostic language. In nursing school, formal NANDA diagnosis writing is required for care plans and exams. Understanding the formal taxonomy builds the underlying reasoning that translates to clinical practice even when the exact NANDA phrasing isn't used at the bedside.

Care Plans: How Nursing Diagnoses Drive Nursing Action

A nursing care plan is structured around nursing diagnoses: for each nursing diagnosis, the care plan specifies the expected patient outcomes (using NOC language in formal academic care plans) and the nursing interventions (using NIC language) that will achieve those outcomes. The evaluation section documents whether outcomes were met.

In clinical practice, care plans in electronic health records (Epic, Cerner, Meditech) typically prompt nurses to select nursing diagnoses and associated interventions from structured pick lists rather than write full three-part statements. The underlying logic — nursing assessment identifies a problem, a standardized diagnostic label names it, nursing interventions address it, outcomes are evaluated — is the same regardless of format.

Priority-setting in care plans: not all nursing diagnoses are equal in urgency. Using Maslow's hierarchy (physiological needs before psychological needs before self-actualization) and the actual vs. risk distinction (actual problems before risk problems) helps students and nurses prioritize which diagnoses to address first when resources or time are constrained. An "Impaired Gas Exchange" is prioritized before "Anxiety" not because the anxiety doesn't matter but because the patient cannot address anxiety if they cannot breathe.
