Nursing Diagnosis vs Medical Diagnosis (With 20 Side-by-Side Examples)
A medical diagnosis names the disease. A nursing diagnosis names the patient's response to it that nurses can treat. Pneumonia is a medical diagnosis; impaired gas exchange is a nursing diagnosis. The same patient usually has one medical diagnosis and several nursing diagnoses, and the nursing diagnoses can change from shift to shift while the medical one stays the same.
The difference at a glance
| Medical diagnosis | Nursing diagnosis | |
|---|---|---|
| Describes | A disease, injury or condition | The patient's response to a health problem or life process |
| Made by | Physician or nurse practitioner | Registered nurse |
| Focus | Cause and cure | Function, comfort, safety, coping, learning |
| Changes | Usually stays the same during the illness | Changes as the patient's response changes |
| Classification | ICD (International Classification of Diseases) | NANDA-I (in many programs) |
| Leads to | Medical treatment (drugs, surgery) | Nursing interventions within nursing scope |
| Example | Type 2 diabetes | Deficient knowledge of blood glucose self-monitoring |
20 side-by-side examples
| Medical diagnosis | Possible nursing diagnoses |
|---|---|
| Pneumonia | Impaired gas exchange; Ineffective airway clearance |
| Heart failure | Excess fluid volume; Activity intolerance |
| Type 2 diabetes (new) | Deficient knowledge; Risk for unstable blood glucose level |
| Hip fracture (post-operative) | Acute pain; Impaired physical mobility; Risk for falls |
| Stroke | Impaired verbal communication; Risk for aspiration; Self-care deficit |
| COPD exacerbation | Ineffective breathing pattern; Anxiety |
| Dementia | Chronic confusion; Risk for injury; Caregiver role strain (family) |
| Sepsis | Risk for shock; Hyperthermia |
| Major depressive disorder | Hopelessness; Risk for suicide |
| Chronic kidney disease | Excess fluid volume; Risk for electrolyte imbalance |
| Pressure injury | Impaired skin integrity; Risk for infection |
| Post-partum | Risk for bleeding; Readiness for enhanced breastfeeding |
| Appendectomy (post-op) | Acute pain; Risk for surgical site infection |
| Opioid-induced constipation | Impaired intestinal elimination |
| Breast cancer (on chemotherapy) | Fatigue; Risk for infection; Disturbed body image |
| Asthma (child) | Ineffective airway clearance; Deficient knowledge (parents, inhaler technique) |
| Alcohol withdrawal | Risk for injury; Anxiety |
| Rheumatoid arthritis | Chronic pain; Impaired physical mobility |
| Schizophrenia | Social isolation; Ineffective coping |
| Total knee replacement | Acute pain; Risk for falls; Impaired physical mobility |
Labels use the wording most textbooks and care plan templates still teach. The NANDA-I 2024 to 2026 edition revised 98 labels and merged some (constipation, for example, is now a defining characteristic of impaired intestinal elimination), so check the exact label against the edition your program uses.
How to write a nursing diagnosis statement
Nursing diagnoses come in three main types. Each has its own structure.
| Type | Structure | Example |
|---|---|---|
| Problem-focused | [Diagnosis] related to [cause] as evidenced by [signs and symptoms] | Acute pain related to surgical incision as evidenced by pain rating 7/10, guarding and grimacing on movement |
| Risk | Risk for [diagnosis] as evidenced by [risk factors] | Risk for falls as evidenced by post-operative opioid use, age 82 and unfamiliar environment |
| Health promotion | Readiness for enhanced [area] as evidenced by [patient's expressed wish] | Readiness for enhanced nutrition as evidenced by patient asking for a diabetic meal plan |
Some programs teach PES format (Problem, Etiology, Signs and symptoms) for problem-focused diagnoses. It's the same structure under a different name.
Mistakes that lose marks
| Mistake | Example | Fix |
|---|---|---|
| Using the medical diagnosis | "Pneumonia related to infection" | Name the response: "Impaired gas exchange related to..." |
| Medical diagnosis as the cause | "Acute pain related to hip fracture" | Accepted by some programs; many prefer the nursing-treatable cause: "related to tissue trauma from surgery" |
| Restating the same thing | "Acute pain related to pain" | The "related to" must be a cause, not the problem again |
| No evidence | "Anxiety related to surgery" | Add "as evidenced by" with what you observed and the patient said |
| Risk diagnosis with symptoms | "Risk for infection as evidenced by fever" | If the sign is already present, it's no longer a risk; use a problem-focused diagnosis |
| A diagnosis nurses can't treat | "Ineffective cardiac output" when only medical treatment applies | Choose a response nursing interventions can change |
How nursing and medical diagnoses work together
In a care plan, the medical diagnosis is context. The nursing diagnoses drive the plan:
- Medical diagnosis: Heart failure (from the chart).
- Assessment data: 2 kg weight gain in 48 hours, bilateral ankle oedema, crackles at both bases.
- Nursing diagnosis: Excess fluid volume related to reduced cardiac function as evidenced by weight gain, oedema and crackles.
- Goal: Weight returns to within 0.5 kg of baseline within 72 hours.
- Interventions: Daily weight at the same time and scale, fluid intake and output each shift, administer prescribed diuretic and monitor response, teach low-sodium diet.

Frequently asked questions
What is the main difference between a nursing diagnosis and a medical diagnosis?
A medical diagnosis identifies a disease. A nursing diagnosis identifies the patient's response to that disease (or to a life process) that nurses can treat independently.
Can a nurse make a medical diagnosis?
Registered nurses don't make medical diagnoses. Nurse practitioners can, within their scope of practice.
Is "pain" a nursing diagnosis or a medical diagnosis?
Acute pain and chronic pain are nursing diagnoses. The condition causing the pain, such as a fracture, is the medical diagnosis.
How many nursing diagnoses should a care plan have?
Many student care plans ask for 2 or 3, prioritized. Check your rubric.
Do Canadian nursing programs use NANDA-I?
Many do, but not all. Some programs use clinical problem statements instead. Follow your program's preferred format.
What is a risk nursing diagnosis?
A problem that hasn't happened yet but could, based on risk factors. It has no "related to" or signs and symptoms; it lists risk factors instead.
