Which statement differentiates subjective and objective data in nursing assessment?

• A. Subjective data are measurable; Objective data are what the patient reports
• B. Subjective data refer to personal opinions of the clinician; Objective data are laboratory values
• C. Subjective data are observable signs; Objective data are patient descriptions
• D. Subjective: what the patient reports; Objective: measurable/observable data

Answer: (D)

Subjective data come from the patient’s own reports about symptoms, feelings, and perceptions, while objective data are measurable or observable findings obtained through examination, vital signs, and tests. The best statement aligns with this: what the patient reports is subjective, and what can be measured or observed is objective. For example, a patient might say they have headaches and dizziness (subjective), while the nurse notes a temperature, blood pressure, pulse, and unsteady gait (objective). The other options mix up these definitions or limit objectivity to single types of data, which is why they don’t fit as well.
