The occupational nurse is advising a client on options to enhance workplace communication because the client has progressive hearing loss. The client works as a customer service representative. In discussing the options with the client, which type would be the last option offered by the nurse?
- A. Battery-operated hearing aid
- B. American sign language
- C. Headsets with amplifiers
- D. Text-based telecommunications
Correct Answer: B
Rationale: Although American sign language is an asset to use for communication, a client with an occupation of customer service representative needs accommodations to be able to understand the spoken word.

There are several types of hearing loss. Which type of hearing loss benefits from the use of a hearing aid?
- A. Sensorineural
- B. Conductive
- C. Genetic
- D. Acquired
Correct Answer: B
Rationale: Diminished hearing results from a conductive loss, sensorineural loss, or both. Clients with a conductive hearing loss benefit more from the use of a hearing aid because the structures that convert sound into energy and facilitate perception of sound in the brain continue to function. Genetic and acquired are not types of hearing loss.
The nurse is caring for a client with symptoms of ototoxicity from aminoglycoside administration. On which structure does the medication produce the ototoxic effect?
- A. The auditory canal
- B. The eighth cranial nerve
- C. The tympanic membrane
- D. The cochlear nerve
Correct Answer: B
Rationale: Ototoxicity describes the detrimental effect of aminoglycosides on the eighth cranial nerve. Signs and symptoms include tinnitus and sensorineural bearing. The other options are not related to the ototoxic effects.
The nurse is teaching a family member how to instill ear drops to the client to remove impacted cerumen. What is important to teach this family member?
- A. Insert the irrigating syringe deeply.
- B. Direct the flow of the ear drops toward the eardrum.
- C. Refrigerate before instillation.
- D. Place the container in warm water before instillation.
Correct Answer: D
Rationale: If irrigation or instillation of liquids is ordered, the liquid should be warmed to body temperature by placing the container in warm water. Cold or hot liquids cause dizziness, and the potential for injury exists if the liquid is hot. The family member should avoid inserting the irrigating syringe too deeply so as not to close off the auditory canal. The family member should direct the flow toward the roof of the canal, rather than the eardrum.
The nurse is caring for a client with recurrent ear infections. The nurse assesses the client for further infectious processes traveling deeper into the tissue and becoming more lethal. Which infection, originated in the ear, is of most concern?
- A. Mastoiditis
- B. Meningitis
- C. Sinusitis
- D. Labyrinthitis
Correct Answer: B
Rationale: The infection stemming from the ear may extend to the meninges, causing meningitis, or a brain abscess could occur. This could be life threatening. The other options are also potential complications of an ear infection but not as much of a concern as meningitis.
The nurse is caring for a client experiencing hearing loss. The nurse uses the otoscope to assess the ear canal and tympanic membrane and notes a significant accumulation of cerumen. Which documentation of hearing loss type would be accurate?
- A. Conductive
- B. Mixed
- C. Central
- D. Sensorineural
Correct Answer: A
Rationale: Conductive hearing loss occurs from an obstruction in the outer or middle ear such as from cerumen. Mixed hearing loss is a combination of conductive and sensorineural problems. Central hearing loss involves injury or damage to the nerves or the nuclei of the central nervous system. Sensorineural involves damage to the inner ear.
