What is an objective indication that can be evaluated by a physician?

The correct answer is a sign because a sign is an objective indication of a medical condition that can be observed or measured by a physician during an examination or through diagnostic tests. Signs are typically physical findings that a healthcare provider can observe, such as a rash, swelling, fever, or abnormal lab results. These observations are independent of the patient's feelings or interpretations, which makes them objective and reliable indicators of health status.

In contrast, symptoms are subjective experiences reported by the patient, such as pain or fatigue, which cannot be measured directly by the physician. Subjective reports and personal observations, similarly, rely on the patient's own account or perspective, which can vary widely from person to person and cannot be objectively verified. Therefore, they do not provide the same level of objective data needed for medical evaluation and diagnosis.
