Which type of data is information that is observed and leaves little room for interpretation, such as vital signs and wound characteristics?

• A. Objective data
• B. Subjective data
• C. Demographic data
• D. Experimental data

Answer: (A)

Observed, measurable facts fall under objective data. These are the kinds of information you can verify through examination or instruments, such as vital signs (blood pressure, pulse, respirations, temperature) and wound characteristics (size, depth, color, drainage). They are not about personal interpretation or patient feelings; they represent what can be counted or observed by anyone using the same method. In contrast, subjective data are the patient’s reported experiences, like pain level, dizziness, or nausea, which can vary based on perception. Demographic data describe who the patient is (age, sex, ethnicity) and are identifying information, not measurements. Experimental data come from research settings and are not typically part of routine bedside assessment.
