Final answer:
A physical exam is assessed from the perspective of the healthcare provider, using objective measures and medical expertise to evaluate a patient's health.
Step-by-step explanation:
While the review of systems involves the patient's personal perception of their symptoms being either positive or negative, a physical exam is determined based on the point of view of the healthcare provider. This is because during a physical exam, the healthcare provider is actively evaluating the patient's physical state using their medical expertise and diagnostic skills to objectively assess the patient's health. For instance, a neurologist assessing a patient's neurological function will conduct various tests such as checking tongue movements to evaluate the functioning of the hypoglossal nerve, testing muscular strength, and sensory perception to pinpoint potential areas of damage in the nervous system.
