The nurse is instructing a client on the benefits of a cochlear implant. The client asks, 'How am I able to interpret sound?' The nurse credits which of the following as significant in the production of hearing?
- A. External microphone
- B. Internal processor
- C. Amplifier
- D. Auditory nerve
Correct Answer: D

An amplifier is used with typical hearing aids.
A nursing student is presenting a report on M?©ni?¨re disease to other members of the class. What symptom would the student list?
- A. Pinkish-orange eardrum
- B. Nystagmus of the eyes
- C. Enlarged lymph nodes behind the ear
- D. Swelling and redness in the auditory canal
Correct Answer: B
Rationale: Nystagmus of the eyes may occur in a client with M?©ni?¨re disease caused by an imbalance in vestibular control of eye movements. Pinkish-orange eardrums, enlarged lymph nodes, or swelling and redness in the auditory canal are not observed in a client with M?©ni?¨re disease.
The nurse is instructing a client's family members on the most incapacitating symptom of M?©ni?¨re disease. Which nursing instruction associated with the symptom is most helpful?
- A. Assist the client when ambulating.
- B. Keep a bucket beside the bed.
- C. Ensure low lighting in the room.
- D. Sit in front of the client when speaking.
Correct Answer: A
Rationale: The most incapacitating symptom of M?©ni?¨re disease is vertigo. When the client is experiencing vertigo or dizziness, gait becomes unsteady. Having a person assist the client when ambulating is most helpful in preventing falls. Keeping a bucket at the bedside is helpful if the client is experiencing nausea. Photophobia is not a main symptom of M?©ni?¨re disease. If the client experiences hearing loss, being able to see the nurse's lips may be helpful.

- D. Hearing loss, vertigo, tinnitus
Correct Answer: D
Rationale: Hearing loss, vertigo, and tinnitus are common symptoms of many disease processes but, when placed together, indicate M?©ni?¨re disease. The other options do not include the accurate triad of symptoms.
