Which of the following is an example of a symptom?

A symptom is defined as a subjective indication of a disease or condition, experienced and reported by the patient. In this context, chest pain serves as an excellent example of a symptom because it is a feeling that the patient experiences and communicates to the healthcare provider. The presence of chest pain can indicate various underlying health issues, but it is inherently linked to the patient's personal experience.

On the other hand, a fever represents a measurable sign of illness, not a subjective experience. It can be objectively determined through temperature readings rather than reported by the patient. Blood pressure readings are also objective measurements taken by healthcare professionals and do not reflect the patient's personal sensations. Similarly, physical exam findings consist of observable facts noted during a medical evaluation, which again do not represent the patient's subjective experiences. Thus, chest pain stands out as the clear example of a symptom, as it is rooted in the individual's perception of their health condition.
