Answer to Question 1

A
CN III, the oculomotor nerve, is responsible for accommodation. Failure of a pupil to accommodate reflects an abnormality in this cranial nerve. CN V, the trigeminal nerve, controls the corneal reflex, chewing, and biting. CN VIII, the acoustic nerve, plays a role in hearing and the sense of balance. CN X, the vagus nerve, affects heart rate, peristalsis, swallowing, and the gag reflex.

Answer to Question 2

C
The nurse's first response is to assess that the person is actually choking and then rapidly proceed to intervene performing abdominal thrusts. Back blows are not indicated in adults with obstructed airways and might actually create a complete obstruction by dislodging a foreign body that was only partially blocking the airway.
