What Is Clinical Judgment?

Clinical judgment is the nurse's ability to interpret patient data, identify the most important problem, decide on the best course of action, and evaluate whether it worked — in real time, under uncertainty.

It is distinct from knowledge. You can know every drug in a pharmacology textbook and still struggle to decide which one a specific patient needs, in a specific situation, right now.

The NCSBN Clinical Judgment Measurement Model (CJMM)

The NGN is built around the NCSBN CJMM, a six-layer thinking framework:

1

Recognise Cues

Which information in the clinical scenario is relevant? Filter signal from noise. Not everything in a patient chart matters right now.

2

Analyse Cues

What do the relevant cues mean? Connect findings to pathophysiology. Why is this patient's potassium low? What explains these vital sign changes?

3

Prioritise Hypotheses

What is the most likely or most urgent problem? Rank your clinical hypotheses. Life-threatening conditions always rank first.

4

Generate Solutions

What are the possible interventions for this problem? Think broadly, then narrow to what is appropriate for this patient.

5

Take Actions

Which intervention is the priority? What is the sequence? Consider safety, scope of practice, and available resources.

6

Evaluate Outcomes

Did the interventions work? What findings would indicate improvement or deterioration? Be specific.

How to Develop Clinical Judgment Before Your Exam

  1. Apply the CJMM to every practice question — before selecting an answer, identify which layer the question is testing
  2. Read every rationale — even for correct answers. Understanding why an option is wrong develops judgment.
  3. Do full case studies — isolated questions build knowledge; case studies build judgment
  4. Think out loud — narrating your reasoning as you work through questions identifies gaps
  5. Review your wrong answers by layer — if you consistently miss “evaluate outcomes” questions, that's your gap
