Question:
The Weber test uses a tuning fork to test hearing. The frequency range closest to that of
conversational speech would be one with a frequency of:
256 Hz.512 Hz. Correct800 Hz.1000Hz.
Explanation:
The Weber hearing test screens for unilateral conductive hearing loss with a tuning fork. The
tuning fork is measured in frequencies of 256 Hz or 512 Hz. These frequencies fall within the
range of conversational speech. The ideal frequency for the Weber test is 256 Hz. A frequency
of 512 Hz is the ideal frequency for the Rinne hearing test.

In optic atrophy, there is death of the optic nerve fibers. This leads to loss of the tiny disc vessels
giving a white appearance. A pink and hyperemic disc is seen in patients with papilledema. The
normal disc appears yellowish-orange to creamy pink and the disc vessels are tiny with disc
margins that appear sharp. A pale disc with a backward depression is characteristic of
glaucomatous cupping.
Question:
Ophthalmoscopic examination of the retina reveals AV banking. This appears as if the:

vein tapes down on either side of the artery.vein is twisted on the distal side of the artery.
Correctvein crosses beneath the artery. Incorrectvein stops abruptly on either side of the artery.
Explanation:
When the arterial walls lose their transparency, changes appear in the arteriovenous crossings.
Decreased transparency of the retina probably contributes to AV nicking and AV tapering. In AV
nicking, the vein appears to stop abruptly on either side of the artery. In tapering, the vein
appears to taper down either side of the artery. In the normal eye, the vein appears to cross
beneath the artery. With banking, the vein appears to be twisted on the distal side of the
artery and forms a dark wide knuckle appearance.
Question:
Causes of sensorineural hearing loss include all of the following except:
aging.loud noises over prolonged periods of time. Incorrectperforated tympanic
membrane. Correctacoustic neuroma.
Explanation:
A perforated tympanic membrane is an example of a cause of a conductive hearing loss.

Sensorineural hearing loss involves disorders of the cochlear nerve, cochlea, and an
interruption in the neuronal impulse transmission to the brain. Causes include: exposure to loud
noises, inner ear infections, acoustic neuroma, aging, and congenital and/or familial disorders.
Question:
What visual acuity constitutes legal blindness?
