ATI Fundamentals 5 Practice Test

Subjective data is information the patient reports about their own experiences, feelings, and symptoms. It relies on the patient’s own description and cannot be verified by measurements. For example, statements like “I have a headache,” “I feel nauseated,” or “I’m dizzy” are subjective data. This contrasts with objective data, which are observable and measurable, such as a fever, blood pressure reading, or a rash seen on examination. Administrative data involves nonclinical details like age or insurance, not the patient’s symptoms. Family-reported data can supplement when the patient can’t communicate, but subjective data specifically centers on what the patient says about their condition.
