What is an example of an objective symptom?

An objective symptom is one that can be observed and measured by someone other than the patient, such as a healthcare professional. Redness is a classic example of an objective symptom because it can be visibly seen and documented during an examination. This observable sign indicates potential inflammation, irritation, or an allergic reaction.

In contrast, symptoms like itching, dryness, and pain are considered subjective symptoms. These are based on the individual's personal experience and cannot be quantified or externally observed. Instead, they rely on the person's description of their feelings or sensations, which makes them subjective by nature. Thus, redness stands out as the correct answer for an objective symptom.
