A patient with a peripheral nerve injury has an NCS performed 2 days post-injury. Results demonstrate normal conduction below the level of the injury and no response across the injured axon. Which of the following nerve injuries is most likely?
A) Cannot be determined at this time
B) Neurapraxia
C) Axonotmesis
D) Neurotmesis

Question
