9. Answer: (B) The needle should be withdrawn and redirected more superiorly ⢠⢠⢠The stimulation pattern described indicates ulnar nerve stimulation. Advancing to a deeper position in the axilla when stimulating the ulnar nerve would not be expected to place the needle closer to the desired median nerve. Advancing to a deeper position when stimulating the ulnar nerve might recruit fibers from the radial nerve. The stimulation pattern described indicates ulnar nerve stimulation. Withdrawing and redirecting inferiorly when stimulating the ulnar nerve would not be expected to place the needle tip closer to the desired median nerve. The stimulation pattern described indicates ulnar nerve stimulation. An optimal needle position would place the needle tip next to the median nerve. (B) Withdrawing and redirecting more superiorly would place the needle tip in the proximity of the median nerve
