What type of data describes symptoms like nausea, pain, or dizziness?

The correct choice, which is subjective data, refers to information that is based on personal reports, feelings, or opinions shared by the individual experiencing the symptoms. When a patient describes sensations like nausea, pain, or dizziness, they are communicating their internal experiences, which are inherently subjective and cannot be measured or observed directly by someone else.

In contrast, objective data would involve measurable and observable facts that can be assessed by caregivers. This might include vital signs, lab results, or physical examination findings that do not rely on personal interpretation. Assessment and diagnosis, while important aspects of healthcare, relate to evaluating and interpreting both subjective and objective data to determine a patient's condition, rather than being types of data on their own. Therefore, subjective data appropriately captures the essence of the symptoms being reported, emphasizing the individual’s own experience of their illness or discomfort.
