Define subjective data versus objective data in nursing documentation and give an example of each.

• A. Subjective data are patient-reported symptoms; objective data are measurable observations (e.g., blood pressure 110/70).
• B. Subjective data are measured vitals; objective data are patient feelings.
• C. Subjective data are lab values; objective data are imaging results.
• D. Subjective data are the nurse's interpretations; objective data are guesses.

Answer: (A)

Subjective data are information the patient communicates about their experiences, symptoms, and feelings, such as pain level, dizziness, or nausea. Objective data are what the nurse can observe or measure directly, using senses or instruments, like vital signs or physical findings. The example given—blood pressure 110/70—fits objective data because it’s a measurable measurement. In contrast, patient-reported symptoms or descriptions (e.g., “I have a headache” or “my pain is a 6 out of 10”) are subjective data recorded from the patient’s perspective. In nursing documentation, you’d capture the patient’s reported experience in their own words and document the measurement separately as objective data. Lab values and imaging results are also objective, while relying on the nurse’s interpretation or guesses does not constitute objective or subjective data.
