Subjective data refers to information that comes directly from the patient’s own perspective and experience. This type of data includes symptoms, feelings, perceptions, and self-reports. During history-taking, healthcare professionals gather subjective data by asking patients about their symptoms, pain levels, emotional state, and overall health experiences. This input is crucial because it provides insight into the patient's condition from their own viewpoint, which can guide diagnosis and treatment plans.

The other choices pertain to various types of objective data, which are based on observable and measurable factors. This includes observations made by healthcare providers, documented medical records, and findings from physical examinations, all of which rely on external assessment rather than the individual's personal account. Understanding the distinction between subjective and objective data is vital for effective clinical practice and patient care.
