A client with impaired hearing is having a test to measure the compliance of the middle ear to sound transmission. The nurse would instruct the client about which of the following diagnostic tests?
1. Rinne test
2. Weber test
3. Tympanometry
4. Acoustic reflex
3. Tympanometry
Rationale:
The tympanometry is an indirect measurement of the compliance and impedance of the middle ear to sound transmission. The external auditory meatus is subjected to neutral, positive, and negative air pressure while the resultant sound energy flow is monitored.
The Rinne and Weber tests assess bone and air conduction with the use of a tuning fork. Acoustic reflex testing uses a tone presented at various intensities to evaluate movement of the structures of the middle ear.
