Which of the following describes subjective data?

Subjective data refers to the personal accounts, feelings, and experiences that a patient expresses about their health, symptoms, and overall condition. This type of data is inherently personal and reflective of the individual's perspective, making it crucial for understanding the patient's experience of their health.

When a patient describes their pain level, mood, or any other internal experience, they provide subjective data that cannot be measured or observed by others in a direct way. This information is essential for healthcare professionals, as it helps in assessing patient needs, planning care, and evaluating treatment outcomes.

The other choices focus on types of data that are either objective—measurable and observable through direct assessment or medical equipment—or are based on external statistical information, which does not capture the personal experiences or feelings of the patient. Thus, the emphasis on the patient's own words and feelings makes the correct answer distinctly valuable in nursing and healthcare.
