Question

In reviewing education for the patient who is receiving a cochlear implant, which statement

indicates the need for additional teaching?
A. "The microphone retrieves sound from the environment."
B. "The electrodes send the impulses to different regions of the auditory nerve."
C. "The speech processor selects and arranges sounds received from the
microphone."
D. "The transmitter receives signals from the microphone and converts them into
impulses."

Answer 1

The cochlear implant consists of several components that work together to restore hearing. The statement that indicates the need for additional teaching is that the microphone retrieves sound from the environment.

Step-by-step explanation:

The cochlear implant consists of several components that work together to restore hearing in people with nonfunctional cochleae:

The microphone picks up sound and converts it into an electrical signal.

The speech processor selects sounds in the range of human speech.

The transmitter converts the sounds into electrical impulses.

The electrical impulses are sent to the auditory nerve.

Based on this information, the statement that indicates the need for additional teaching is:

A. "The microphone retrieves sound from the environment."

This is incorrect because the microphone does not retrieve sound from the environment.

It only picks up sound and converts it into an electrical signal.

The sound is actually retrieved by the microphone and then processed and transmitted to the auditory nerve.
