A client has a hearing loss resulting from chronic mastoiditis. The cause of this type of hearing loss is:
1. Inflammatory.
2. Mechanical.
3. Obstructive.
4. Sensorineural.
Inflammatory.
Rationale: The cause of hearing impairment can be categorized as mechanical, inflammatory, or an obstructive disorder. An inflammatory cause of hearing loss is the result of an inflammatory process caused by an infection. Mastoiditis is a bacterial infection of the mastoid bone. Acute or chronic infection of the mastoid process can lead to changes in hearing and balance. A mechanical cause is the result of problems with the structures of the ear. An obstructive cause is a partial or complete blockage of the ear canal. Sensorineural is a type of hearing loss, not a cause.
