The following tests are designed to help identify the functioning of the twelve pairs of cranial nerves on a patient or “test subject”. Review the following cranial nerve tests. study the case scenarios to determine which cranial nerve (there may be more than 1 for some) may be damaged in each scenario based on the results of cranial nerve tests “you” (as a pretending physician) have performed on some patients. Note that “CN” stands for “cranial nerve”. Use the images attached to help. Case Scenario #1 You are a neurologist seeing a patient who is having trouble with her hearing. You perform a cranial nerve test by having her try to identify an object by its sound. Behind your back you jingle a bell, clap your hands, snap your fingers. The patient indicated that she heard the jingling of the bell, but not the other two sounds. You perform another test where you have the patient walk along a line on the floor. The patient walks in a zig-zag type pattern. What nerve might be damaged in this person? Case Scenario #2 You are a family doctor, and a mother brings in her child who has fallen off his jungle gym in the backyard. She wants you to check to make sure that he is okay. She noticed that he didn’t seem to have any broken bones, but wants him to be “checked over” for sure. After you check his arms and legs and skull for broken bones and wounds, and have ruled out a concussion, you do a couple of cranial nerve tests. You show the child a funny picture, have him smell some vinegar, and you note his responses. After performing these tests, you snap a photo of the child. This is what he looked like (after viewing the funny picture and smelling something unpleasant). The child had a straight face. You have a suspicion that one of his cranial verves is damaged. Which one do you suspect? Case Scenario #3 A wife brings her husband to the medical office, complaining that he is slurring his words. She is worried that he may have had a stroke. You are able to rule that out, but you perform a cranial nerve test by asking the patient to stick out his tongue and move it first to the left and then to the left. The patient is only able to move his tongue in one direction. What is your assessment after this nerve test? Case Scenario #4 Your neighbor, Jim, comes into your clinic complaining that he is having some issues turning his head, that his neck muscles seem weak. You perform a cranial nerve test on Jim and find that he cannot lift his right shoulder when you ask him to shrug his shoulders. You notice also that his right shoulder is not even with his left shoulder. You are concerned that Jim may have nerve damage to his ______________ nerve.
