Answer to Question 2

Correct Answer: 4
Tuning forks are used to determine whether a hearing loss is conductive or perceptive. The Weber test is performed by placing the base of a vibrating tuning fork on the midline vertex of the patient's head. Sound is normally heard equally in both ears. If the sound is not heard equally, the cause may be a buildup of cerumen, an infection such as otitis media, or perforation of the eardrum. In the Rinne test, a vibrating tuning fork is placed on the patient's mastoid bone to determine the conduction of sound by bone and air conduction. In a tympanogram, a measuring device is inserted into the ear canal to measure the pressure of the middle ear and observe the tympanic membrane's response to waves of pressure. In the auditory precision test, the patient sits in a soundproof room and raises a hand when sounds are heard.
