Answer to Question 1

ANS: D
The following normal findings are expected when testing the spinal accessory nerve (CN XI): The patient's sternomastoid and trapezius muscles are equal in size; the person can forcibly rotate the head both ways against resistance applied to the side of the chin with equal strength; and the patient can shrug the shoulders against resistance with equal strength on both sides. Checking the patient's ability to hear normal conversation checks the function of CN VIII. Having the patient stick out the tongue checks the function of CN XII. Testing the eyes for nystagmus or strabismus is performed to check CNs III, IV, and VI.

Answer to Question 2

ANS: A
Questions regarding reflexes include such questions as, What have you noticed about the infant's behavior, Are the infant's sucking and swallowing seem coordinated, and Does the infant grasp your finger? The other responses are incorrect.
