Objective Data

Measurable, observable information the nurse collects

Definition

Objective data are observable, measurable findings collected during assessment. They are verifiable by others and include vital signs, physical exam findings, lab results, and behavior.

Examples

  • Blood pressure 142/88
  • Temperature 38.7°C
  • Patient grimacing while walking
  • Clear amber urine
  • Hemoglobin 11.2 g/dL
  • Crackles in right lower lobe

Contrast With Subjective Data

Subjective data = what the patient reports (e.g., 'My chest hurts 7/10'). Objective data = what the nurse observes/measures.

Documentation

Document objective data clearly, quantifiably, and in measurable terms. Avoid subjective interpretations or judgments.

NCLEX Relevance

Tested in nursing process and documentation. Objective data support nursing diagnoses.
