Step-by-step explanation:
The review of systems is used to document subjective symptoms that the patient may have forgotten to mention or that may have seemed unimportant. It is a way for the healthcare provider to gather information about a patient's symptoms or possible issues that may not have been brought up during the examination. On the other hand, the physical exam involves the healthcare provider conducting an assessment of the patient’s body using various techniques, such as observing, palpating, percussing, and auscultating. This is done to collect objective symptoms or signs of a medical condition.
