How is objective data primarily collected during assessments?

Objective data is primarily collected during physical examinations because this method involves direct observation and measurement of the patient's physical condition by a healthcare professional. During these examinations, clinicians assess various aspects of the patient's health, such as vital signs, appearance, and physical functioning, using equipment and techniques that provide measurable and quantifiable information.

This type of data is distinguished from subjective data, which relies on the patient's personal experiences and perceptions gathered through interviews or self-reports. While medical records and laboratory analysis can provide valuable information, they are often considered supporting sources of objective data rather than primary means of collection during the assessment process itself.
