A nurse is testing a client for conduction deafness by performing the Weber's test. Which of the following actions should the nurse take when performing this test?
Place the base of a vibrating tuning fork on the top of the client's head.
Count how many seconds a client can hear a tuning fork after it has been struck.
Place the base of a vibrating tuning fork on the client's mastoid process.
Move a vibrating tuning fork in front of the client's ear canals one after the other.
The Correct Answer is A
The correct answer is that the nurse should place the base of a vibrating tuning fork on the top of the client's head when performing Weber's test. Weber's test is a screening test for hearing that can detect unilateral (one-sided. conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss)².
Options b, c and d are not correct actions for performing Weber's test. Counting how many seconds a client can hear a tuning fork after it has been struck, placing the base of a vibrating tuning fork on the client's mastoid process and moving a vibrating tuning fork in front of the client's ear canals one after the other are not part of Weber's test.
