1.  In mammals, the most variations of the ear happen in the
  1. Semicircular canals
  2. Utricle
  3. Cochlea
  4. Saccule
2.  Based on comparative mammalian data, a larger semicircular canal arc radius is generally associated with:
  1. Reduced vestibular sensitivity in head movement
  2. Greater sensitivity to angular rotations
  3. Increased susceptibility to otitis media
  4. Slower locomotion
3.  In the large UK canine epidemiology review presented, vestibular disease was found to be most prevalent in:
  1. Brachycephalic breeds
  2. Toy breeds
  3. Dogs under 2 years old
  4. Dogs with cropped ears
4.  Which of the following canine and feline breeds have been identified as having a recognized congenital peripheral vestibular syndrome?
  1. Labrador Retriever and Persian cat
  2. Border Collie and Maine Coon cat
  3. Dachshund and Bengal cat
  4. German Shepherd and Siamese cat
5.  Which of the following would be least consistent with idiopathic peripheral vestibular syndrome?
  1. Sudden onset in an older dog
  2. Nausea, circling, and horizontal nystagmus
  3. Progressive behavior change and aggression
  4. Gradual improvement over days to weeks
6.  A young dog experiences transient vestibular episodes that worsen with play or eating and persist intermittently over months. This pattern is most with:
  1. Pituitary apoplexy
  2. Ototoxicity
  3. Otitis Media Interna
  4. Cerebellar hypoplasia
7.  What is the average age off onset for idiopathic peripheral vestibular ataxia in canines?
  1. 1 year old
  2. 5.4 years old
  3. 9 years old
  4. 12.5 years old
8.  In animals, a way to evaluate nystagmus vision denied is:
  1. Penlight cover test
  2. Goggles with cover on
  3. Put patient in a dark room
  4. Frenzel lenses
9.  To evaluate vestibular strabismus in animals
  1. Tilt head up and eye will deviate ventrally on the lesioned side
  2. Tilt head up and eye will deviate ventrally on the healthy side
  3. Tilt head down and eye will deviate ventrally on the lesioned side
  4. Tilt head down and eye will deviate ventrally on the healthy side
10.  Which diagnostic tool is used to distinguish peripheral from central vestibular disease?
  1. Otoscopy
  2. Nystagmus direction
  3. Advanced imaging
  4. Age and breed of animal
