Question 1

Which of the following would be characteristics of a central vestibular pathology?

Accepted Answer

D

Question 2

A patient complains of dizziness and imbalance with loud noises and when coughing.She also reports she can hear her heart beat in one ear.This patient most likely has:

Accepted Answer

The symptoms described, including dizziness and imbalance triggered by loud noises or coughing and hearing one's heartbeat in one ear, are indicative of superior canal dehiscence. This condition involves a thinning or absence of part of the bone that covers the superior semicircular canal of the inner ear, leading to these specific symptoms.

Question 3

Posterior canal BPPV is characterized by:

Accepted Answer

Posterior canal BPPV is characterized by upbeat torsional nystagmus due to the involvement of the posterior semicircular canal.

Question 4

According to research by Schubert (2004) the Horizontal Head Thrust Test is most sensitive when the patient's head is flexed

Accepted Answer

Schubert's research indicates that the Horizontal Head Thrust Test reaches its highest sensitivity when the patient's head is flexed at 30 degrees. This position optimizes the test's ability to detect vestibular deficits by aligning the horizontal semicircular canals with the plane of head movement.

Question 5

When performing the Dix-Hallpike Test the therapist should first:

Accepted Answer

The Dix-Hallpike Test, used to diagnose Benign Paroxysmal Positional Vertigo (BPPV), involves rotating the patient's head 45 degrees to one side before moving them from a long-sitting to a supine position. This maneuver aims to provoke vertigo and nystagmus by moving the otoliths within the semicircular canals of the inner ear.

Question 6

Based on evidence by Marchetti (2006) the 4-item Dynamic Gait Index (DGI) can:

Accepted Answer

The answer of Based on evidence by Marchetti (2006) the...

Question 7

A therapist is using the sidelying test to examine the posterior canal for BPPV.Which of the following statements would be true?

Accepted Answer

The answer of A therapist is using the sidelying test...

Question 8

Which of the following would be characteristics of a peripheral vestibular pathology?

Accepted Answer

Peripheral vestibular pathologies often present with sudden onset of vertigo, torsional or horizontal nystagmus, and may include hearing loss, which aligns with option C.

Question 9

A 76 year-old patient complains of falling at least once every 2 weeks in a variety of situations and he is concerned about the frequency of falls increasing.Which outcome measure might best assess this patient's fall risk?

Accepted Answer

The Activities-Specific Balance Confidence Scale is specifically designed to assess the level of confidence a person has in performing various activities without falling, making it an appropriate tool to evaluate fall risk in this patient.

Question 10

A patient with a complaint of vertigo that began 48 hours ago is presenting with horizontal eye movements with slow phases directed toward right side and quick phases directed toward the left side.The therapist is most likely observing:

Accepted Answer

The description of horizontal eye movements with slow phases directed toward the right side and quick phases directed toward the left side indicates spontaneous nystagmus, which is often a sign of vestibular dysfunction. The direction of the slow phase (toward the right) suggests a lower tonic output from the vestibular system on the right side, leading to the correct answer being spontaneous nystagmus due to the low tonic output on the right.

Question 11

Which of the following outcome measures was found to have excellent test-retest, (inter-rater and intra-rater reliability) when used with school-aged children with mild to moderate impairment?

Accepted Answer

The Pediatric Balance Scale has been shown to have excellent test-retest, inter-rater, and intra-rater reliability when used with school-aged children with mild to moderate impairment.

Question 12

Which of the following assessment tools would best assess a patient's functional problems related to vestibular dysfunction?

Accepted Answer

The Balance Evaluation Systems Test (BESTest) is designed to assess balance and functional problems, which are often affected by vestibular dysfunction.

Question 13

Which of the following are components of the peripheral vestibular system?

Accepted Answer

The peripheral vestibular system includes the otoliths, vestibular nerve, and sensory hair cells, which are involved in detecting head movements and maintaining balance.

Question 14

A patient with a vestibular disorder complains of decreased concentration,feeling embarrassed when around people outside of his immediate family,and difficulty doing light house work.Which outcome measure would best evaluate the emotional aspect of his complaints?

Accepted Answer

The Dizziness Handicap Inventory (DHI) is specifically designed to assess the impact of dizziness on a patient's quality of life, including emotional aspects such as embarrassment and decreased concentration. It evaluates the physical, emotional, and functional effects of dizziness and vestibular disorders, making it the best choice for this scenario.

Question 15

A patient complains of her hearing fading in and out,high-pitch ringing in the left ear,and episodes of severe spinning lasting for 2 hours once every 3 months.This patient has symptoms consistent with:

Accepted Answer

Meniere's disease is characterized by episodes of vertigo, fluctuating hearing loss, tinnitus (often described as high-pitched ringing in the ear), and a feeling of fullness in the affected ear. The symptoms described by the patient match those of Meniere's disease, including the episodic nature of the vertigo lasting a few hours and the auditory symptoms.

Question 16

A patient complains of sudden onset of spinning,with imbalance,nausea,and vomiting for the past 24 hours.This patient has symptoms consistent with:

Accepted Answer

Vestibular neuritis is characterized by sudden onset of vertigo, nausea, and vomiting, often without hearing loss, which aligns with the symptoms described. It typically presents with a single episode of vertigo lasting hours to days, not triggered by changes in head position.
