What is located in the cochlea of the inner ear?
- A. Semicircular canals
- B. Labyrinth
- C. Vestibulocochlear nerve
- D. Organ of Corti
Correct Answer: D

The nurse is caring for geriatric clients who state that they are prescribed reading glasses. Some individuals state needing assistance with seeing writing far away, and others need assistance with closer vision. What does the nurse understand to be related to visual changes caused by aging?
- A. Changes in refraction
- B. Changes in the visual field
- C. Changes in central vision
- D. Changes in accommodation
Correct Answer: D
Rationale: The changes that occur in vision during aging, which include difficulty reading and the need for reading glasses, include changes in accommodation. Accommodation occurs when the ciliary muscles contract or relax to focus an image on the retina.

The nurse is caring for a client who just returned from a trip requiring an airline flight. The client reported ear pain upon descent. The nurse is correct in stating which site as being the pressure equalizer in the ear?
- A. Eustachian tube
- B. Auricle
- C. Tympanic membrane
- D. Labyrinth
Correct Answer: A
Rationale: The eustachian tube extends from the floor of the middle ear to the pharynx. It equalizes air pressure in the middle ear. The auricle is the fleshy portion of the outer ear which funnels sound waves to the inner ear. The tympanic membrane is the eardrum. The labyrinth is the inner ear which contains fluid.
The nurse is assessing a client's hearing using the Rinne test. When providing instruction to elicit client feedback, which instruction is essential?

- B. Raise your hand when you no longer hear sound.
- C. Raise your hand when the vibration exceeds the sound.
- D. Raise your hand when the sound exceeds the vibration.
Correct Answer: B
Rationale: It is essential to provide clear directions on when the client is to notify the nurse of client response. The information gleaned from the response is what the nurse uses to interpret the test. The correct time to induce feedback is when the vibration is heard.
