The Nursing Process: A Practical Thinking Framework
Learn the five-step nursing process used to organize patient care and clinical thinking.
1. Why the Nursing Process Matters Today
The nursing process is a five-step, cyclical thinking framework used worldwide to organize patient care:
- Assessment
- Nursing Diagnosis (or Nursing Problem Identification)
- Planning
- Implementation
- Evaluation
It is endorsed by major professional bodies (e.g., the American Nurses Association and the International Council of Nurses) and underpins how nurses document and deliver care in modern electronic health records.
Key ideas:
- It is systematic: you follow the same structure for every patient.
- It is patient-centered: focused on the patient's responses, not just the disease.
- It is dynamic: you loop through the steps repeatedly as the situation changes.
In your previous module, you learned what nurses do and where they work. The nursing process is how they think and organize that work in hospitals, community care, long‑term care, mental health, and more.
> As you go through this module, keep asking: “Where am I in the process right now?”
2. Overview of the Five Steps (Big Picture)
Before we go deeper, anchor the five steps with simple, working definitions:
- Assessment – Collect and verify data about the patient's health status (subjective and objective).
- Nursing Diagnosis – Analyze the data to identify actual or potential nursing problems (patient responses) and prioritize them.
- Planning – Set goals (outcomes) and choose evidence-based nursing interventions to address the prioritized problems.
- Implementation – Carry out the planned interventions and document what you did.
- Evaluation – Check results: Did the patient move toward the goals? If not, what needs to change?
Visual description (mental image):
- Imagine a circle with 5 arrows in order: Assessment → Diagnosis → Planning → Implementation → Evaluation → back to Assessment.
- Each time you evaluate, you decide whether to continue, modify, or end the care plan.
You will now walk through each step using one running patient scenario.
3. Step 1 – Assessment (Collecting Meaningful Data)
Scenario
You are caring for Mr. Lee, 72 years old, admitted with pneumonia.
Subjective data (what the patient says):
- “I feel so short of breath when I walk to the bathroom.”
- “My chest hurts when I cough.”
- “I’m scared I won’t get better.”
Objective data (what you observe/measure):
- Respiratory rate: 26 breaths/min, shallow
- Oxygen saturation: 90% on 2 L/min via nasal cannula
- Temp: 38.5 °C (101.3 °F)
- Productive cough with thick yellow sputum
- Uses accessory muscles to breathe, sits leaning forward
- Chest auscultation: crackles in right lower lobe
- Appears anxious, fidgeting, frequently asking for reassurance
What good assessment looks like:
- Systematic: You use a structure (e.g., head-to-toe, body systems, or Gordon’s functional health patterns).
- Holistic: You include physical, psychological, social, and environmental data.
- Ongoing: You reassess when something changes (e.g., new shortness of breath, new pain).
> At this stage, you do not jump to conclusions. Your job is to observe, ask, listen, and measure.
4. Practice Sorting Assessment Data
Classify each item as subjective (S) or objective (O). Write your answers on paper or in your notes.
- “My pain is 8 out of 10.”
- Blood pressure 168/94 mmHg.
- Nurse notes patient grimacing and guarding abdomen.
- “I feel dizzy when I stand up.”
- Heart rate 112 beats/min, irregular.
Check yourself (hover mentally or fold the page):
- 1: S
- 2: O
- 3: O
- 4: S
- 5: O
Reflect: Why does it matter?
Because subjective data come only from the patient’s report, while objective data can be observed or measured by others. Both are essential for accurate nursing diagnosis.
5. Step 2 – Nursing Diagnosis & Prioritization
Once data are collected, you analyze and cluster them to identify nursing diagnoses (or nursing problems).
In current practice (including NANDA‑I terminology used in many curricula), a nursing diagnosis often follows this pattern:
> Problem related to Etiology as evidenced by Signs/Symptoms
> (PES format: Problem–Etiology–Signs/Symptoms)
From Data to Nursing Diagnoses (Mr. Lee)
Cluster 1 – Breathing:
- RR 26, shallow; O₂ sat 90% on 2 L; crackles; uses accessory muscles; short of breath with minimal exertion.
Possible nursing diagnosis:
- Impaired Gas Exchange related to alveolar‑capillary membrane changes secondary to pneumonia as evidenced by O₂ saturation 90% on 2 L and crackles in right lower lobe.
Cluster 2 – Pain:
- “Chest hurts when I cough”; grimacing; holds chest when coughing.
Possible nursing diagnosis:
- Acute Pain related to respiratory infection and coughing as evidenced by patient report of chest pain and guarding behavior.
Cluster 3 – Anxiety:
- “I’m scared I won’t get better”; appears anxious; frequently seeks reassurance.
Possible nursing diagnosis:
- Anxiety related to health status and hospitalization as evidenced by verbalization of fear and restlessness.
Prioritization
Use frameworks like:
- ABCs (Airway, Breathing, Circulation)
- Maslow’s hierarchy (physiological needs before psychological)
- Safety first
For Mr. Lee, the priority order is likely:
- Impaired Gas Exchange (Breathing – life‑threatening if not managed)
- Acute Pain (affects breathing, coughing, mobility)
- Anxiety (important, but less immediately life‑threatening)
> Nursing diagnoses focus on patient responses (e.g., impaired gas exchange, anxiety), not medical labels (e.g., pneumonia).
6. Quick Check: Identifying the Best Nursing Diagnosis
Use the information about Mr. Lee to choose the most appropriate, highest‑priority nursing diagnosis.
Which nursing diagnosis should be **addressed first** for Mr. Lee based on the data provided?
- Anxiety related to hospitalization as evidenced by restlessness and verbalization of fear
- Impaired Gas Exchange related to alveolar‑capillary membrane changes as evidenced by O₂ saturation of 90% on 2 L and crackles in the right lower lobe
- Acute Pain related to coughing as evidenced by patient report of chest pain and guarding behavior
Show Answer
Answer: B) Impaired Gas Exchange related to alveolar‑capillary membrane changes as evidenced by O₂ saturation of 90% on 2 L and crackles in the right lower lobe
Impaired Gas Exchange is the highest‑priority problem because it directly affects oxygenation and breathing (ABCs). While pain and anxiety are important, they are not as immediately life‑threatening as compromised gas exchange.
7. Step 3 – Planning: Goals and Interventions
In planning, you translate your prioritized diagnoses into a clear plan of care.
1) Set SMART Goals/Outcomes
Goals should be S.M.A.R.T.:
- Specific
- Measurable
- Achievable
- Realistic/Relevant
- Time‑bound
Example (Impaired Gas Exchange – Mr. Lee):
- Short‑term goal:
“Mr. Lee’s oxygen saturation will remain ≥ 94% on 2 L/min via nasal cannula within the next 4 hours.”
Example (Anxiety):
- “Within 24 hours, Mr. Lee will report a decrease in anxiety from 8/10 to ≤ 4/10 and demonstrate use of at least one coping strategy (e.g., deep breathing).”
2) Choose Evidence‑Based Nursing Interventions
Interventions should be:
- Directly linked to the diagnosis and goals.
- Based on current best evidence (e.g., national guidelines, institutional protocols).
- Specific about what, how often, and under what conditions.
Sample interventions for Impaired Gas Exchange:
- Monitor respiratory rate, depth, and O₂ saturation at least every 2 hours and with any change in condition.
- Position patient in high‑Fowler’s or semi‑Fowler’s to optimize lung expansion.
- Encourage and assist with deep breathing and coughing every hour while awake.
- Collaborate with provider/respiratory therapist regarding oxygen titration according to facility protocol.
> In many settings, these plans are entered into an electronic care plan that auto‑links diagnoses, goals, and interventions.
8. Write a Simple Plan of Care (Mini Exercise)
Using Mr. Lee’s Acute Pain diagnosis, draft one SMART goal and two nursing interventions.
Diagnosis reminder:
Acute Pain related to respiratory infection and coughing as evidenced by patient report of chest pain and guarding behavior.
- Write one SMART goal in your notes. Example structure:
“Within [time frame], the patient will [specific, measurable change in pain].”
- List two nursing interventions you (as the nurse) can perform or coordinate.
Sample answers (compare with yours):
- Goal: “Within 8 hours, Mr. Lee will report a decrease in chest pain from 7/10 to ≤ 3/10 at rest.”
- Intervention 1: Assess pain using a standard pain scale every 4 hours and before/after analgesic administration.
- Intervention 2: Teach and assist Mr. Lee to use a splinting technique (holding a pillow to the chest) when coughing to reduce discomfort.
Reflect: Did your goal specify time, measurement, and realistic improvement? Did your interventions clearly describe what you will do and how often?
9. Steps 4 & 5 – Implementation and Evaluation in Practice
Step 4 – Implementation
This is where you do the plan and document it.
For Mr. Lee, implementation might include:
- Positioning him in high‑Fowler’s and re‑checking his comfort.
- Guiding him through deep breathing and coughing exercises every hour.
- Administering prescribed analgesics on schedule and before physiotherapy.
- Providing calm explanations about treatments to reduce anxiety.
- Documenting what you did, when, and how the patient responded.
Implementation is not just tasks; it includes communication, education, coordination, and advocacy.
Step 5 – Evaluation
After implementing, you ask:
- Were the goals met, partially met, or not met?
- What evidence do I have? (vital signs, patient reports, observations)
- What needs to change? (goals, interventions, or even the diagnosis)
Example (Impaired Gas Exchange goal):
- Goal: O₂ sat ≥ 94% on 2 L within 4 hours.
- After 4 hours: O₂ sat is 95% on 2 L, RR 20, less use of accessory muscles.
- Evaluation: Goal met. Continue current plan, monitor for further improvement, consider gradual weaning per protocol.
If the goal was not met, you would:
- Reassess (new data? new complications?).
- Modify interventions (e.g., more frequent monitoring, consult respiratory therapy).
- Possibly revise the nursing diagnosis if the problem has changed.
> Evaluation is not the end; it loops you back to Assessment in a continuous cycle of clinical reasoning.
10. Apply the Full Nursing Process to a New Scenario
Use the nursing process to reason through this short case.
Ms. Ortiz, 60, had abdominal surgery yesterday. She rates her pain as 9/10 and refuses to get out of bed, saying, “It hurts too much to move.” Her incision is clean and dry, vital signs are stable. Which **nursing diagnosis and priority action** best reflect the nursing process?
- Nursing diagnosis: Risk for Infection; Priority action: Monitor temperature every 4 hours.
- Nursing diagnosis: Impaired Physical Mobility related to postoperative pain; Priority action: Manage pain adequately and assist with early ambulation as ordered.
- Nursing diagnosis: Deficient Knowledge; Priority action: Provide written discharge instructions.
Show Answer
Answer: B) Nursing diagnosis: Impaired Physical Mobility related to postoperative pain; Priority action: Manage pain adequately and assist with early ambulation as ordered.
The key problem is that severe postoperative pain is limiting mobility, which can delay recovery and increase complications (e.g., DVT, pneumonia). The best nursing diagnosis is Impaired Physical Mobility related to postoperative pain, and the priority action is to manage pain effectively and assist with early ambulation according to postoperative protocols.
11. Flashcard Review: The Five Steps & Key Ideas
Use these flashcards to quickly review core terms and concepts from the nursing process.
- Assessment
- The systematic collection, verification, and organization of subjective and objective data about the patient’s health status. It is ongoing and holistic.
- Nursing Diagnosis
- A clinical judgment about a patient’s response to actual or potential health problems, forming the basis for nursing interventions. Often written in PES format: Problem–Etiology–Signs/Symptoms.
- Prioritization (ABCs)
- A method for choosing which nursing problems to address first, focusing on Airway, Breathing, and Circulation, followed by safety and other needs.
- Planning (SMART Goal)
- The step where nurses set Specific, Measurable, Achievable, Realistic/Relevant, and Time‑bound outcomes and select appropriate nursing interventions.
- Implementation
- The phase where nurses carry out the planned interventions, including direct care, education, coordination, and documentation of actions and patient responses.
- Evaluation
- The step where nurses determine whether goals were met, partially met, or not met, using observable data, and then continue, modify, or end the care plan.
- Subjective Data
- Information reported by the patient, such as feelings, perceptions, and concerns (e.g., “I feel short of breath”).
- Objective Data
- Observable and measurable information, such as vital signs, physical examination findings, and lab results.
- PES Format
- A structure for nursing diagnoses: Problem related to Etiology as evidenced by Signs/Symptoms.
- Cyclical Nature of the Nursing Process
- The idea that the process is not linear; after evaluation, nurses reassess and adjust diagnoses, plans, and interventions as the patient’s condition changes.
12. Summarize the Nursing Process in Your Own Words
To consolidate your learning, take 2–3 minutes to do this brief reflection activity.
- Write one sentence (in your own words) that explains what the nursing process is and why it is used.
- List the five steps from memory. Then check:
- Did you include: Assessment, Nursing Diagnosis, Planning, Implementation, Evaluation?
- Think of a clinical or simulated experience you’ve had (or imagine one). Ask yourself:
- Which step of the nursing process was I in?
- What would the next step be?
If you can:
- Explain the process,
- Name all five steps in order, and
- Sketch a simple plan of care for a basic scenario (like Mr. Lee or Ms. Ortiz),
then you have met this module’s learning objectives.
