How to Write a Nursing Care Plan: Assessment to Evaluation

15 August 2026 · 8 min read

Nursing students write care plans from the first semester to the final placement, and the same weakness shows up throughout: interventions listed without reasons. A care plan is an argument that a specific patient problem, evidenced by specific data, will be improved by specific actions for specific physiological reasons. Every column has to connect to the one before it.

Start with assessment data, split in two

Keep subjective and objective data separate. Subjective is what the patient reports — pain described as sharp and rated 7 out of 10, breathlessness on walking to the bathroom. Objective is what you measure or observe — respiratory rate 26, SpO2 91% on room air, crackles at the lung bases, a wound with purulent exudate. Everything later in the plan must be traceable to something in this section.

Write the diagnosis in three parts

Use the problem, aetiology and evidence structure: "Impaired gas exchange related to alveolar-capillary membrane changes as evidenced by SpO2 of 91% on room air, respiratory rate of 26 and reported breathlessness on exertion." The problem comes from a recognised nursing diagnosis list, the aetiology explains why it is happening, and the evidence is lifted directly from your assessment. Medical diagnoses — pneumonia, heart failure — do not belong in this column.

Goals must be measurable and time-bound

"Patient will maintain SpO2 above 94% on 2L nasal cannula within 8 hours" — measurable and checkable.
"Patient will report pain of 3 or less on a 0–10 scale within 1 hour of analgesia" — specific and timed.
"Patient will demonstrate correct inhaler technique before discharge" — observable.
"Patient will feel better" — unmarkable; avoid it.

Distinguish short-term goals (this shift, next few hours) from long-term goals (by discharge). Markers look for both where the condition warrants it.

Every intervention needs a rationale

This is the column that separates a pass from a distinction. "Elevate the head of the bed to 45 degrees" is the intervention; "to reduce diaphragmatic pressure and improve lung expansion, increasing tidal volume" is the rationale. Where you can, support the rationale with a citation from a textbook or guideline — most rubrics award marks explicitly for evidence-based justification. Include assessment, therapeutic, educational and collaborative interventions rather than only tasks.

Evaluation closes the loop

Evaluate against the exact wording of your goal: met, partially met or not met, with the data that shows it. If a goal was not met, say what you would change — a revised target, a different intervention, or escalation to the medical team. A care plan that ends with every goal fully met and no reflection tends to read as fiction.

Before you submit

Check every piece of evidence in your diagnoses appears in the assessment section.
Prioritise diagnoses using ABC or Maslow — airway and safety problems come first.
Anonymise the patient completely; no names, hospital numbers or identifying details.
Reference rationales in the style your school requires, usually APA or Harvard.
Read the rubric one final time — many allocate marks per column, so an empty column is a guaranteed loss.
