What kind of observation refers to data that is visible, palpable, or measurable?

Objective observation refers to data that is visible, palpable, or measurable, which means it is based on observable facts rather than personal feelings or opinions. This type of observation is crucial in the health sciences because it provides concrete evidence that healthcare professionals can rely on to make informed decisions regarding a patient’s condition.

In a clinical setting, objective observations can include vital signs like heart rate and blood pressure, laboratory test results, and any visible signs of illness, such as swelling or discoloration. Such observations allow healthcare providers to track a patient's progress over time and make assessments that are based on clear, quantifiable data rather than subjective interpretations.

Other types of observations, like subjective observations, are based on the patient's personal experiences, feelings, or perceptions, which can vary significantly from one individual to another and may not be as reliable for assessing physical health. In contrast, objective observations are universally applicable and grounded in measurable phenomena.
