Nursing Case Study Examples & How to Write One

The nursing case study is one of the most common — and most marked-down — assessments in undergraduate and postgraduate nursing. It asks you to do something deceptively hard: take a single patient, apply the full cycle of clinical reasoning, and show that your decisions are grounded in evidence rather than habit. Students lose marks not because they lack knowledge, but because they describe what happened instead of analysing why, and because they let the structure drift. This guide gives you a complete worked example using an illustrative patient, then breaks down exactly how to build your own and what markers reward — the same analytical discipline that underpins any strong case study.

Key points

• Use a recognised framework — the nursing process (ADPIE) is the safest default.
• Every clinical decision must be tied to current evidence and, where relevant, NMC standards or local guidelines.
• Anonymise the patient completely — confidentiality is both an ethical and an assessment requirement.
• Markers reward analysis and rationale, not description. Always answer “why”.
• End with honest evaluation and reflection, not a summary.

What a nursing case study actually assesses

A nursing case study is not a story about a shift. It is evidence that you can think like a safe, accountable practitioner. Examiners are looking for four things: that you can gather and prioritise assessment data; that you can translate that data into accurate nursing diagnoses; that you can plan and justify interventions against current best evidence; and that you can evaluate outcomes honestly and adjust. Underpinning all of this is professional accountability — in the UK, alignment with the Nursing and Midwifery Council (NMC) Code, and everywhere, respect for patient confidentiality and dignity.

The single biggest conceptual error students make is treating the case study as descriptive when it is analytical. “The patient was given paracetamol” is description. “Paracetamol was selected as first-line analgesia because the patient’s pain was mild-to-moderate and non-inflammatory, and because it avoided the gastrointestinal risks of NSAIDs given her history” is analysis. The second sentence earns marks; the first does not.

Choosing your framework

Before you write a word, decide which framework structures your analysis. The three most widely used in nursing education are:

• The Nursing Process (ADPIE) — Assessment, Diagnosis, Planning, Implementation, Evaluation. The most flexible and the default for most case studies.
• Roper–Logan–Tierney (Activities of Living) — structures assessment around twelve activities of living. Strong for holistic, whole-person assessments.
• Gibbs’ Reflective Cycle — used for the reflective component many case studies require at the end.

For the worked example below we use ADPIE, because it maps cleanly onto the clinical reasoning examiners want to see and because it works across almost every clinical setting.

“Description tells the reader what happened. Analysis tells them why it mattered and what you decided as a result — and only analysis earns marks.”

A complete worked example (illustrative patient)

1. Patient background

Mrs A is a 68-year-old woman admitted to an acute medical ward with a two-day history of increasing breathlessness, a productive cough with green sputum, and a fever. She has a background of type 2 diabetes (diet-controlled) and hypertension. On admission she appears flushed, is using accessory muscles to breathe, and reports feeling “exhausted”. A provisional medical diagnosis of community-acquired pneumonia has been made. This section sets the scene: it gives the reader the clinical context without yet interpreting it. Keep it concise and relevant — include only the history that bears on the care you will go on to discuss.

2. Assessment

A structured assessment is the foundation of the whole case study. Using a recognised tool such as the ABCDE approach (Airway, Breathing, Circulation, Disability, Exposure) demonstrates systematic, safety-first thinking:

Crucially, a strong case study does not just list observations — it interprets and prioritises them. Here, the National Early Warning Score (NEWS2) would be elevated, driven primarily by the respiratory rate and oxygen saturation, flagging the patient as at risk of deterioration and requiring escalation. Identifying that the breathing problem is the immediate priority — and explaining why — is exactly the clinical reasoning markers reward.

3. Nursing diagnosis

Nursing diagnoses differ from the medical diagnosis (pneumonia): they describe the patient’s responses to the condition that nursing care can address. For Mrs A, prioritised diagnoses might be:

Writing diagnoses in the recognised “problem – related to – evidenced by” format shows you can connect cause, effect and evidence. Prioritising them — gas exchange first, because it is the most immediately life-threatening — demonstrates safe clinical judgement.

4. Planning

For each diagnosis, set SMART goals (specific, measurable, achievable, relevant, time-bound) and plan interventions justified by evidence. For impaired gas exchange:

• Goal: oxygen saturation maintained at or above 94% within four hours (or the target range set for this patient).
• Interventions: administer oxygen as prescribed and titrate to target; position the patient upright to optimise lung expansion; monitor respiratory rate, saturation and NEWS2 at least hourly; escalate per protocol if the patient deteriorates.

Every intervention should have a stated rationale grounded in evidence or guideline — for example, upright positioning improves ventilation–perfusion matching and reduces the work of breathing. This is where you cite the literature and local policy.

5. Implementation

Implementation describes the care delivered and, importantly, how you delivered it safely and in partnership with the patient and team. For Mrs A this would include administering prescribed oxygen and antibiotics within the recommended window (timely antibiotics are strongly associated with better outcomes in pneumonia), encouraging oral fluids, monitoring blood glucose given her diabetes and the physiological stress of infection, and communicating clearly with the multidisciplinary team. Note where you escalated, who you involved, and how you maintained the patient’s dignity and informed consent throughout.

6. Evaluation

Evaluation closes the loop: did the interventions meet the goals? Suppose that after four hours Mrs A’s oxygen saturation has risen to 95% on low-flow oxygen, her respiratory rate has settled to 20, and her temperature is falling. The gas-exchange goal is partially met; care continues. If a goal is not met, say so honestly and explain what you would change — this demonstrates the reflective, self-correcting practice that markers value far more than a tidy “everything worked” ending.

Worked example: a second prioritised diagnosis

To show how the cycle repeats for each problem, here is the second diagnosis — hyperthermia — worked through in full, because a strong case study addresses more than one diagnosis rather than analysing a single problem in isolation.

• Goal (SMART): the patient’s temperature returns to within the normal range (36.1–37.2°C) within eight hours, and she reports improved comfort.
• Interventions and rationale: administer prescribed antipyretics and antibiotics promptly, because treating the underlying infection is the definitive intervention for an infective fever; encourage oral fluids to offset insensible losses and support thermoregulation; monitor temperature and the wider NEWS2 at least hourly to detect deterioration early; promote rest and a comfortable environment.
• Evaluation: if the temperature falls to 37.4°C at eight hours and the patient reports feeling cooler and more comfortable, the goal is partially met and care continues. If it does not fall, this prompts re-assessment — is the antibiotic appropriate, is there a source not yet identified, does the patient need escalation? Documenting that reasoning is exactly what distinguishes an analytical case study from a descriptive one.

Notice the pattern: each diagnosis runs through the same goal–intervention–rationale–evaluation loop. Once you have internalised that rhythm, the structure of any nursing case study becomes predictable, and you can focus your energy on the quality of the reasoning rather than on what comes next.

The reflection component (Gibbs applied)

Many nursing case studies require a reflective section, and Gibbs’ Reflective Cycle is the most widely used model. Applied to Mrs A’s care, a concise reflection might move through Gibbs’ six stages: Description (what happened — caring for an acutely breathless patient with pneumonia); Feelings (an honest acknowledgement, for instance, of initial uncertainty about when to escalate); Evaluation (what went well — systematic ABCDE assessment and timely oxygen — and what was harder); Analysis (why the NEWS2 score was the turning point that prompted escalation, supported by the evidence on early warning systems); Conclusion (what you now understand about recognising deterioration); and an Action plan (how you will apply this — for example, escalating earlier and more confidently in future). Reflection is assessed on insight and honesty, not on presenting yourself as flawless.

Using evidence and references effectively

Evidence is the difference between an opinion and a defensible clinical decision. In a nursing case study, draw on current sources — ideally within the last five years — including peer-reviewed journals, national clinical guidelines (such as NICE in the UK), and professional standards (the NMC Code). Avoid leaning on textbooks alone, which date quickly, and never rely on non-academic websites. Integrate evidence into your reasoning rather than bolting it on: a citation should appear at the exact point where it justifies a decision, not in a vague cluster at the end of a paragraph. Most nursing programmes require Harvard or APA referencing; apply it consistently, because inconsistent referencing is one of the easiest ways to shed marks on an otherwise strong piece. Finally, make sure every source in your reference list appears in the text and vice versa.

How to write your own nursing case study: step by step

1. Select and anonymise your patient. Choose a case rich enough to analyse but focused enough to manage within the word count. Remove all identifying details.
2. Choose your framework (ADPIE is the safe default) and signpost it in your introduction.
3. Gather and prioritise assessment data using a structured tool (ABCDE, NEWS2).
4. Write prioritised nursing diagnoses in the problem–related to–evidenced by format.
5. Plan SMART goals and evidence-based interventions, each with a rationale.
6. Describe implementation with attention to safety, consent and teamwork.
7. Evaluate honestly against your goals.
8. Reflect (often using Gibbs) on what you learned and would do differently.
9. Reference rigorously — current evidence, NMC standards and local guidelines, in your required style (usually Harvard or APA).

What the marking criteria reward

Although wording varies between universities, nursing case-study rubrics consistently reward the same things: depth of clinical reasoning (not description), integration of current evidence, correct application of the chosen framework, professional and ethical awareness (confidentiality, consent, accountability), and clarity of structure and referencing. If you map your draft against those five dimensions before submission, you will catch most of the gaps that lose marks.

Common mistakes that lose marks

• Describing instead of analysing — the single most common and costly error. Always answer “why”.
• Breaching confidentiality — including any identifying detail can cap or fail the work.
• Unsupported claims — every clinical decision needs an evidence base.
• Ignoring prioritisation — listing problems without ranking them by clinical urgency.
• A “perfect” evaluation — markers distrust case studies where everything went flawlessly; honest reflection scores higher.
• Weak referencing — outdated sources or inconsistent Harvard/APA formatting.

Adapting the case study to your level

Expectations rise with academic level, and matching your depth to your level is part of scoring well. At undergraduate level, markers want to see safe, systematic application of the nursing process, accurate diagnoses and evidence-informed care — correctly done fundamentals. At postgraduate or advanced-practice level, the same structure is expected, but with far greater critical depth: weighing conflicting evidence, questioning the limitations of guidelines, considering the wider determinants of the patient’s health, and demonstrating leadership in the coordination of care. A common reason capable postgraduate students underperform is that they write an excellent undergraduate case study — technically correct but insufficiently critical for the level. Before you start, re-read your learning outcomes and calibrate the depth of analysis accordingly.
