Question

which of the following diagnostic procedures assesses both nerve and bone conduction of sound?
a audiometry
b rinne and weber tuning - fork test
c otoscopy
d falling test

Explanation:

• Audiometry measures hearing acuity but doesn't specifically focus on differentiating nerve and bone conduction in the way the question asks.
• Otoscopy is an examination of the external ear canal and tympanic membrane, not related to nerve and bone conduction of sound.
• Falling test is not related to assessing sound conduction in the ear.
• The Rinne test compares air conduction (nerve - related in a sense as it involves the cochlea and auditory nerve pathway for normal perception) and bone conduction. The Weber test also helps in differentiating conductive (related to bone - conduction pathway issues in some cases) and sensorineural (nerve - related) hearing losses. So, the Rinne and Weber tuning - fork test assesses both nerve and bone conduction aspects.

Answer:

B. Rinne and Weber tuning - fork test
