Which data type is gathered from physical examination, laboratory tests, and other diagnostic sources?

• A. Objective data
• B. Subjective data
• C. Planning phase
• D. Health history

Answer: (A)

Objective data are observable, measurable findings collected from physical examination, laboratory tests, and other diagnostic sources. This type of data can be verified by anyone and serves as a concrete basis for assessment, diagnosis, and planning. Examples include vital signs, edema, abnormal lung sounds, and lab or imaging results. In contrast, subjective data are what the patient personally reports, such as pain level or dizziness, which require interpretation and cannot be measured directly by another observer. The planning phase and health history are parts of the nursing process or data collection but do not define the data type itself. Therefore, the best answer is objective data.
