Assessment is more than collecting a complete set of findings. Its purpose is to identify immediate threats, establish what is normal for this person, and gather the information that will change the differential diagnosis or the plan. Clinical reasoning moves through recognizable steps: recognize cues, analyze and cluster the data, generate and rank hypotheses, plan and implement an intervention, and evaluate the response.[2] The sequence is not rigid. A sign of deterioration can move the clinician from history-taking directly to emergency action. Experienced clinicians often notice the patient’s overall appearance before they interpret a single vital sign. Work of breathing, ability to speak, posture, skin colour, level of alertness, motor activity, and ease of movement can reveal physiological stress. A patient who says they are only “a little short of breath” but sits forward, pauses between words, and has new confusion requires an immediate safety assessment rather than a leisurely review of systems.
