Nokea
A patient has been diagnosed with hearing loss related to damage of the end organ for hearing or cranial nerve VIII. What term is used to describe this condition?
- A. Exostoses
- B. Otalgia
- C. Sensorineural hearing loss
- D. Presbycusis
Correct Answer: C
Rationale: Sensorineural hearing loss results from damage to the cochlea or cranial nerve VIII. Exostoses are bony growths, otalgia is ear pain, and presbycusis is age-related hearing loss.

The nurse is discussing the results of a patients diagnostic testing with the nurse practitioner. What Weber test result would indicate the presence of a sensorineural loss?
- A. The sound is heard better in the ear in which hearing is better.
- B. The sound is heard equally in both ears.
- C. The sound is heard better in the ear in which hearing is poorer.
- D. The sound is heard longer in the ear in which hearing is better.
Correct Answer: A
Rationale: In sensorineural hearing loss, the Weber test shows sound lateralizing to the better-hearing ear, as the affected ear has impaired nerve function. Equal hearing or sound in the poorer ear suggests normal hearing or conductive loss.
An advanced practice nurse has performed a Rinne test on a new patient. During the test, the patient reports that air-conducted sound is louder than bone-conducted sound. How should the nurse best interpret this assessment finding?
- A. The patients hearing is likely normal.
- B. The patient is at risk for tinnitus.
- C. The patient likely has otosclerosis.
- D. The patient likely has sensorineural hearing loss.
Correct Answer: A
Rationale: A Rinne test showing louder air-conducted sound indicates normal hearing or sensorineural loss, but in context, normal hearing is most likely. Tinnitus and otosclerosis are not directly assessed by this test.
A patient is being discharged home after mastoid surgery. What topic should the nurse include in discharge teaching?
- A. Expected changes in facial nerve function
- B. The need for audiometry testing every 6 months following recovery
- C. Safe use of analgesics and antivertiginous agents
- D. Appropriate use of OTC ear drops
Correct Answer: C
Rationale: Teaching about analgesics and antivertiginous agents supports safe management of pain and vertigo post-mastoidectomy. Facial nerve changes are complications, audiometry is not routine, and OTC ear drops are not recommended.
A patient has benefited from a cochlear implant. The nurse should understand that this patients health history likely includes which of the following? Select all that apply.
- A. The patient was diagnosed with sensorineural hearing loss.
- B. The patients hearing did not improve appreciably with the use of hearing aids.
- C. The patient has deficits in peripheral nervous function.
- D. The patients hearing deficit is likely accompanied by a cognitive deficit.
- E. The patient is unable to lip-read.
Correct Answer: A,B
Rationale: Cochlear implants are used for profound bilateral sensorineural hearing loss unresponsive to hearing aids. Peripheral nerve deficits, cognitive issues, or inability to lip-read are not prerequisites.
A child goes to the school nurse and complains of not being able to hear the teacher. What test could the school nurse perform that would preliminarily indicate hearing loss?
- A. Audiometry
- B. Rinne test
- C. Whisper test
- D. Weber test
Correct Answer: C
Rationale: The whisper test, assessing the ability to hear a whispered phrase, is a simple screening tool for hearing loss that a nurse can perform. Audiometry, Rinne, and Weber tests require specialized training or equipment.
