Which of the following questions is most likely to be clinically useful in the differential diagnosis of sensorineural versus conductive hearing loss?
A)
"What medications do you currently take?"
B)
"What effect is this hearing loss having on your quality of life?"
C)
"Has your hearing loss developed quickly or more slowly?"
D)
"Do you ever hear a persistent ringing in your ears?"
Ans:
A
Feedback:
Conductive hearing loss occurs when auditory stimuli are not adequately transmitted through the auditory canal, tympanic membrane, middle ear, or ossicle chain to the inner ear. It can be a temporary loss from impacted cerumen. Sensorineural hearing loss occurs with disorders that affect the inner ear, auditory nerve, or auditory pathways to the brain. Numerous drugs have ototoxic potential, a consequence of which is sensorineural hearing loss. The onset and course of hearing loss and the presence or absence of tinnitus do not necessarily help to differentiate between conductive and sensorineural hearing loss. The subjective effect of the client's hearing loss, while a valid concern, does not help with the differential diagnosis.
