A client is diagnosed with an acoustic neuroma in the right ear. The neuroma is removed, but the client still has unilateral hearing loss. The cause of the hearing loss from an acoustic neuroma is categorized as a(n) __________ disorder
1. Obstructive
2. Mechanical
3. Inflammatory
4. Sensorineural
Obstructive
Rationale: The cause of hearing impairment can be categorized as mechanical, inflammatory, or an obstructive disorder. An obstructive cause is a partial or complete blockage of the ear canal. An acoustic neuroma is a benign tumor of the eighth cranial nerve. As the tumor grows, it extends from the internal auditory canal to the cerebellopontine angle. A mechanical cause is the result of problems with the structures of the ear. An inflammatory cause of hearing loss is the result of an inflammatory process caused by an infection. Sensorineural is a type of hearing loss, not a cause.
