Which statement best describes objective data?

Which statement best describes objective data?

• A. Subjective data are reported by the patient.
• B. Objective data rely on patient memory.
• C. Objective data are observable and measurable.
• D. Subjective data require lab tests.

Answer: (C)

Objective data are information that can be observed or measured by someone other than the patient. They are observable and measurable, like a fever, blood pressure, wound size, breathing rate, or lab results. This makes them more verifiable and less influenced by what the patient reports or recalls. The statements describing subjective data fit the other side: information the patient provides about how they feel or what they perceive, such as pain level or dizziness, which can’t be measured directly by a device. Lab tests and imaging produce data that can be measured and observed, not merely described by the patient, so they align with objective data.
