Quizplus · Accepted Answer

In a patient with a laceration that causes an 8-cm cut on the medial plantar aspect of the left foot, a posterior tibial nerve block is most appropriate. The posterior tibial nerve innervates the sole of the foot. To perform a peroneal nerve block, 1 percent lidocaine is injected into the subcutaneous tissue lateral to the posterior tibial artery at the upper border of the medial malleolus.
