A patient reports feeling lightheaded and nauseated; this is an example of which data type?

• A. Objective data
• B. Administrative data
• C. Subjective data
• D. Diagnostic data

Answer: (C)

The key idea here is distinguishing subjective data from other types of health information. When a patient describes how they feel, such as lightheadedness and nausea, that information is subjective data. It’s based on the patient’s personal experience and cannot be directly measured by a clinician. In contrast, objective data are observable and measurable—things like blood pressure, heart rate, or lab results. Administrative data refers to record-keeping details such as demographics and billing information, not symptoms. Diagnostic data consists of test results used to support a diagnosis, like imaging findings or specific lab values. So the patient’s reported symptoms are best categorized as subjective data, since they come from the patient’s own report rather than something you can directly measure.
