Final answer:
The absence of chest discomfort would be a pertinent negative physical exam finding for a patient with chest pain.
Step-by-step explanation:
The pertinent negative physical exam finding for a patient whose chief complaint is chest pain would be the absence of chest discomfort. Chest pain, or angina, is typically felt as pressure or squeezing in the chest and may radiate to other areas such as the arms, neck, and back. Therefore, if a patient does not experience any chest discomfort during the physical exam, it would suggest that their chest pain is not related to a cardiac condition.
