What is an example of objective data collected during patient assessment?

Objective data refers to measurable or observable facts that can be quantified or verified, rather than relying on personal opinions or feelings. In the context of patient assessment, heart rate measured with a monitor exemplifies objective data because it is a numerical value that can be recorded and analyzed independently of the patient’s subjective experience. This data provides a clear and exact measure of the patient's physiological state, which can be consistently replicated and compared against normal values or trends over time.

On the other hand, the other options focus on subjective data, which represents the patient's feelings, perceptions, or interpretations. For instance, a patient-reported pain level and a patient's description of symptoms rely solely on the individual's personal perspective and cannot be independently verified. Similarly, the quality of sleep as reported by the patient is based on their interpretation and perception of their sleep experiences, making it subjective rather than objective.
