A diver is admitted complaining of ear pain and hearing loss. On examination, the nurse notes a rupture in the tympanic membrane. The nurse would conduct further assessment for which type of hearing loss?
1. Conductive hearing loss
2. Sensorineural hearing loss
3. Noise-induced hearing loss
4. Mixed hearing loss
1
Rationale 1: A rupture in the tympanic membrane interferes with sound conduction, so this is a conductive hearing loss.
Rationale 2: Sensorineural hearing loss occurs when the nerves of the inner ear are damaged. Another type of hearing loss is more likely.
Rationale 3: The most obvious reason for the perforation of this patient's tympanic membrane is barotrauma from diving. There is no information to implicate noise as the etiology of this loss.
Rationale 4: There is no assessment data supporting sensorineural hearing loss, one of the components of mixed hearing loss.
