The nurse is assessing a patient who may have hearing loss. Which of these statements is true concerning air conduction?

Question

Quizplus · Accepted Answer

The normal pathway of hearing is air conduction, which starts when sound waves produce vibrations on the tympanic membrane. Conductive hearing loss results from a mechanical dysfunction of the external or middle ear. The other statements are not true concerning air conduction. The frequency of sound waves is what determines pitch, not the amplitude. Vibrations of the bones in the skull are bone conduction, not air conduction. Conductive hearing loss involves mechanical dysfunction of the external or middle ear and is caused by impacted cerumen, foreign bodies, a perforated tympanic membrane, pus or serum in the middle ear, and otosclerosis, not loss of air conduction.
