Which of the following terms is used to refer to what a patient feels or reports?

The term that refers to what a patient feels or reports is "symptom." Symptoms are subjective experiences that cannot be directly observed or measured by someone else, and they are typically described by the patient in their own words. For instance, if a patient says they feel pain, nausea, or dizziness, these feelings are classified as symptoms because they are based on the individual's personal experience and perception of their condition.

In contrast, a sign is an objective finding that can be observed or measured by a healthcare professional, such as a rash or swelling. Indication usually refers to a reason for using a specific treatment or intervention, rather than the patient's personal experience of their condition. Evaluation generally pertains to the assessment process of a patient's condition, which includes both signs and symptoms. Therefore, the definition and context of symptoms distinctly characterize the specific information relayed by a patient regarding their health status.
