accompanying the dizziness are

18
Q

People with psychological dizziness frequently report being dizzy

A

on a continuous basis

19
Q

Drugs that are ototoxic affect the

A

peripheral vestibular system

20
Q

This group of antibiotics is the
most common cause of irreversible ototoxicity and most common cause of bilateral
vestibular dysfunction.

A

Aminoglycosides antibiotics

21
Q

Ototoxic drugs

A

loop diuretics (Lasix), vancomycin (currently used to
treat MRSA), anti-neoplastics, NSAID’s (aspirin – tinnitus – reversible), tetanus antitoxin,
erythromycin (rare and reversible)

22
Q

It is most useful for treating mild to moderate episodes of vertigo and for
prevention of motion sickness

A

Diphenhydramine Hydrocholride (Benadryl)

23
Q

Most useful in preventing nausea and vomiting associated with motion
sickness

A

Scopolamine

24
Q

It is effective for treating mild to moderate episodes
of vertigo and for suppressing motion sickness

A

Meclizine (antivert)

25
Q

This is a vestibular suppressant and anti-emetic agent that is primarily used for prevention
of motion sickness

A

Dimenhydrinate (Dramamine)

26
Q

Useful for
treating severe vertigo with recurrent nausea and vomiting.

A

Phenergan

27
Q

This medication has long been used for treating vertigo, especially vertigo associated with
Meniere’s disease

A

Betahistine

28
Q

A necessary starting point in testing and diagnostic

A

Audiometric Evaluation

29
Q

The faintest sound level at which a patient
can understand and repeat speech at 50%
accuracy

A

Speech recognition threshold

30
Q

Excessive (20% or more) decline in speech
understanding as intensity increases

A

Rollover

31
Q

Scored as the percentage of repeated
correctly of a list of monosyllabic words
presented as varying intensities

A

Speech recognition tests

32
Q

A significant difference in hearing levels between the ears
and indicates the possibility of peripheral vestibular or auditory nerve pathology

A

Auditory asymmetry

33
Q

Auditory evoked potentials

A

used to determine the integrity of the auditory and
vestibular nerve

34
Q

the recording of eye movements during a variety of tests performed to
elicit nystagmus.

A

Nystagmography

35
Q

To assess smooth pursuit eye movements, ask the patient to track

A

a small object about 3 feet

36
Q

Should be examined to detect the presence of characteristic eye
movement abnormalities suggestive of either central or peripheral vestibular system
dysfunction

A

ocular motor system

37
Q

Primary symptoms and signs of individuals with vestibular dysfunction

A

Vertigo
Dizziness/lightheadedness
Nausea and vomiting
Oscillopsia
Nystagmus
Impaired balance

38
Q

Relevant items in the past medical history include

A

allergies, illnesses (such as cardiac or
neurological), medications, and surgeries

39
Q

This tool provides a method of quantifying the symptoms evoked by a set series of
movements

A

Motion Sensitivity Quotient

40
Q

Was developed in response to a perceived to have a
standardized measure of self-report activity limitation and participation restriction
resulting from dizziness and unsteadiness

A

Dizziness Handicap Inventory

41
Q

One can easily assess all three canals for BPPV quickly with the following test procedure.

A
  1. Perform the Hallpike-Dix Maneuver on the left side
  2. Perform the Hallpike-Dix Maneuver on the right side
  3. If the patient has not vertigo: before sitting the patient up from the right side,
    perform a roll test by having the patient turn the head quickly to the left
  4. After 30 seconds, have the patient quickly turn the head back to the right
  5. After 30 seconds, have the patient sit up
42
Q

Because there is no definitive test for __________, the diagnosis is based on the
individual’s signs and symptoms and on the absence of otologic and neurologic causes for
the clinical findings

A

cervicogenic dizziness
