Certified Clinical Medical Assistant Exam Practice Question
Which of the following instruments is used to test hearing by air and bone conduction?
Correct Answer: A
Rationale: A tuning fork is specifically designed to assess hearing through air and bone conduction, making it essential for audiometric evaluations. It produces a pure tone that helps differentiate between conductive and sensorineural hearing loss.
An otoscope is used for examining the ear canal and eardrum, not for testing hearing. A slit lamp is primarily employed in ophthalmology to examine the eyes in detail, while a Wood's lamp is utilized in dermatology to detect certain skin conditions. Thus, these options do not serve the purpose of hearing assessment, highlighting the unique role of the tuning fork in auditory testing.
