Why is it necessary to check more than one vital sign on a patient?

First… without vitals accurately recorded in the chart, a chart audit may fail to confirm the physician's actions and findings.
second… vital signs can be an early indicator of illness, deterioration, or impending adverse event.
lastly, vital signs are important for the physician when evaluating the patient.

Tracking your vital signs provides medical professionals with concrete information that they use to assess your health and form a correct diagnosis. Without vital signs, misdiagnosis can occur and lead to incorrect treatment.
