Physical exam

To test for CVA tenderness, the examiner first applies gentle pressure to the region inside of the CVA with their finger.LeBlond, Richard F., et al. DeGowin's diagnostic examination. New York: McGraw-Hill Education, 2020. Print. If gentle pressure does not elicit tenderness, the examiner places one hand over the region inside the CVA and taps that hand gently with the closed fist of the other hand.
