What is objective data?

• A. Personal opinions
• B. Feelings and beliefs
• C. Patient-reported symptoms
• D. Observable signs (vital signs, lab results)

Answer: (D)

Objective data are observable, measurable facts gathered through assessment—things that can be verified by anyone and do not depend on the patient’s report. This includes signs like vital signs (blood pressure, heart rate, respiratory rate, temperature) and lab results or imaging findings. These data are concrete measurements that can be repeated and tracked over time, providing a reliable basis for evaluating a patient’s condition and response to treatment. In contrast, personal opinions, feelings, beliefs, and symptoms reported by the patient are subjective data, reflecting the patient’s experience rather than an independently verifiable measurement.
