In clinical diagnosis, objective data helps establish which of the following?

• A. Subjective feelings of well-being.
• B. A baseline and confirmation of diagnosis.
• C. Dietary preferences.
• D. A physician's personal impression.

Answer: (B)

Objective data are measurements and observations that can be verified by others, such as vital signs, lab results, imaging findings, or physical exam measurements. They provide the starting point for care—the baseline health status—from which clinicians can track changes over time. They also give solid evidence that supports or refutes a clinical diagnosis, helping to confirm what is suspected. In contrast, subjective feelings of well-being, dietary preferences, and a physician’s personal impression rely on personal report or judgment rather than measurable facts, so they don’t provide the same verifiable foundation.
