Chapter 48: Coordinating care for patients with hearing disorders

Question 1

Anything that obstructs the transmission of sound can impair…?

Answer 1

hearing

Question 2

What type of hearing loss involves a mechanical dysfunction of external or middle ear resulting in partial hearing loss?

Answer 2

Conductive

Question 3

Why us conductive hearing loss considered “partial hearing loss”?

Answer 3

If the amplitude is enough to reach normal nerve elements of the inner ear, the person will be able to hear.

Question 4

What are some causes of conductive hearing loss?

Answer 4

-impacted cerumen
-foreign bodies
-perforated TM
- Pus or blood in middle ear
- Otosclerosis: decrease in mobility of ossicles.

Question 5

What age group is most likely to have conductive hearing loss?

Answer 5

• 20 to 40 years old

Question 6

Sensorineural (perceptive) loss signifies pathology in what 3 areas?

Answer 6

-inner ear
-cranial nerve VIII
- auditory areas of cerebral cortex

Question 7

What is a gradual nerve degeneration that occurs with aging?

Answer 7

Presbycusis

Question 8

What are some signs that you have presbycusis?

Answer 8

• Onset occurs in 50s and slowly progresses
• first notice a high-frequency
  -impairs the ability to localize sounds
  -Accentuated when unfavorable background noise is present

Question 9

What affects hair cells in chochlea, such as gentamycin

Answer 9

Ototoxic drugs

Question 10

A combination of conductive and sensorineural types in same ear.

Answer 10

Mixed hearing loss
