Hearing Loss

What is the cranial nerve that may be affected in a patient diagnosed with sensorineural hearing loss?

8th

Audiologic test

AIR AND BONE CONDUCTION Audiologic testing uses air and bone conduction to assess hearing loss. Otoscopic examination assesses for cerumen impaction.

What will be done to determine if cerumen impaction is creating a patient's hearing loss?

Otoscopic examination

Which behavioral pattern might suggest a potential hearing loss?

Patient frequently asks others to repeat themselves.

A patient is experiencing clinical symptoms of hearing loss and a determination that conductive hearing loss is noted on the medical record. Based on this diagnosis, what might the nurse assume is causing that symptom presentation?

Cerumen impaction

Audiometer

DELIVERS SOUND FREQUENCIES An audiometer test delivers sound frequencies at different intensities to assess the extent of hearing loss. The patency of the ear canal is assessed by performing an otoscopic examination.

The nurse is caring for a patient with a diagnosis of external otitis media. What clinical manifestations could the nurse expect to observe? Select all that apply.

External ear tender to touch Swelling in and around the external ear

Which of the following medications could pose a risk for the development of ototoxicity? Select all that apply.

Furosemide (Lasix) Gentamicin (Garamycin) Cisplatinum (Cisplatin) Acetylsalicylic acid (Aspirin)

Which of the following are risk factors for hearing loss? Select all that apply.

Heredity Advancing age Occupational noises Recreational noises

Which of the following factors can lead to sensorineural hearing loss? Select all that apply.

Lesion in the eighth cranial nerve Lesion noted in the inner ear

The nurse tests for the presence of an acoustic reflex and notes normal findings. What technique does the nurse use to assess for this reflex?

Note if patient's stapedius muscle responds to loud noises.

Acoustic reflex

RESPONSE OF STAPEDIUS MUSCLE Acoustic reflex involves the response of stapedius muscle to loud sounds. With hearing loss, the ability to elicit this reflex would decline.

Speech discrimination test detects:

TYPE OF HEARING LOSS A speech discrimination test is used to determine the type of hearing loss that a patient may be experiencing-conductive, sensorineural, or mixed. Detection of a lisp is not the focus of the test.

A speech discrimination test is ordered for a patient who is suspected to have hearing loss. What is the purpose of this test?

To measure speech intensity

Tympanometry

USED TO ASSESS MIDDLE EAR DAMAGE A tympanometry test is used to assess for middle ear damage by measuring the impedance of the middle ear to acoustic energy.
