A patient is scheduled for diagnostic tests to determine the cause of a hearing and balance disorder. For which diagnostic tests should the nurse prepare this patient?

Select all that apply.
1. tonometry
2. computed tomography (CT) scan
3. electronystagmograp hy (ENG)
4. auditory evoked potentials (AEP)
5. auditory brainstem response (ABR)

Question 2

During a Weber test, a patient is found to have increased hearing in the right ear. The nurse realizes that this finding is consistent with:

1. normal aging.
2. conductive hearing loss in the right ear.
3. possible buildup of cerumen or otitis media in the left ear.
4. perforated left eardrum.

Answer to Question 1

Correct Answer: 3, 4, 5
Diagnostic tests used to determine hearing and balance disorders include audiometry, auditory evoked potential (AEP), auditory brainstem response (ABR), and electronystagmograp hy (ENG). Tonometry is used to measure intraocular pressures. CT scan would note abnormalities in organ structure but would not be helpful in identifying hearing and balance issues.

Answer to Question 2

Correct Answer: 2
During the Weber test, sound heard in, or lateralized to, one ear indicates either a conductive loss in that ear or a sensorineural loss in the other ear. The sound will be louder on the impaired side with a conductive hearing loss; in this case, the right ear. Lateralization is not associated with normal aging. A buildup of cerumen, an infection such as otitis media, or perforation of the eardrum can cause conductive hearing loss. For this patient, the affected ear is the right ear.
