The dog has urate stones in its bladder
Herd of pigs –> unthriftiness, slow growth, and occasional deaths; (some) posterior ataxia or paralysis; herd previously infected w/ Staphanurus dentatus; how to Dx?
Urinalysis
S/E is caused by ketamine
Increase in muscle tone
Also increase in sympathetic tone –> increase in HR, arterial BP and cardiac output; also apneustic breathing pattern and can induce seizures
4-yr old TB race horse; blood on nostrils immediately after racing; previously healthy; presence of rats in the barn, but no documented exposure to rodenticides; best tx to Dx the most likely condition?

Blood gas analysis show hypoxemia and resp acidosis. What is the next best step?
Bilateral thoracocentesis
7 yr old cat, grade II-III/VI L parasternal systolic heart murmur, heart rhythm at 240 bpm, femoral pulses strong and synchronous; what is the top concern?
Hypertrophic cardiomyopathy (most common cause of heart murmur in cats)
Cat have fallen from a high rise; presents w/ dyspnea, blood and abrasions around mouth, and decreased lung sounds dorsally. What to do next?
Thoracocentesis
Traumatic pneumothorax; thoracocentesis prior to any tx or dx tests
Turkey flock; some has crusty, nodular lesions on the head and neck; some lesions are coalescing, many are scabbed; no other Cx, no mortality; fowlpox suspected based on Cx, small population affected, and lack of mortality; best method to stop the spread of dz?
Vaxx all turkeys except those naturally affected
Neonatal isoerythrolysis in a foal most likely to occur in what scenario?
Foal ingests colostrum from an Aa- mare bred to an Aa+ stallion
If you lyse a mature CL, when would you expect to see estrus in a cow?

Glaesserella parasuis
Ave life span of mice
1.5 yrs
15-yr old mare w/ mild, acute laminitis. What tx?
Phenoxybenzamine
Alpha-adrenergic antagonist, promotes vasodilation and restoration of blood flow to digits; Steroids (prednisone) C/I in laminitis!
12-yr old TB horse w/ foot problem; hollow sound over the hoof wall when tapped near the toe; cavity between the hoof wall and underlying lamina along the white line; hoof quality is poor and crumbling; no evidence of laminitis; what is the condition (common name)
Seedy toe
What membrane is “slipped” when diagnosis pregnancy by rectal palpation in a cow?
Chorioallantois
How many legs do lice have? What sp are sucking lice? Biting lice?
6 legs; Anoplura = sucking lice; Mallophaga = biting lice
Causes splenic dilation and decreased Hgb concentration
Acepromazine
Causative agent of Rocky Mountain Spotted Fever
Rickettsia ricketsii
Equine encephalomyelitis w/ the least mortality in horses showing Cx of infxn?
Western equine encephalomyelitis = 50%
VEE = 75%
EEE = 90%
Cattle being shipped is tested for TB intradermally in the caudal fold of each animal then return to the farm 48 hrs later to read the result. One cow is exhibiting very mild thickening at the injection site. The rest has no swelling, sensitivity nor increased skin thickness at the injection sites. What is the next best step.
Wait another 24 hrs and read the TB tests again
Which animals are induced ovulators
Cats, ferrets and rabbits (also camelids)
Newly weaned piglets show snorting, sneezing, ocular discharge and epistaxis. Necropsy showed atrophy of nasal turbinates. What would you find in the culture of the nasal passages of the affected pigs?
Pasteurella multocida or Bordetella bronchiseptica (atrophic rhinitis)
In what dog breed is systemic aspergillosis seen without apparent resp tract involvement
German Shepherd
4-yr old cat not eating has 104.2F (40.1C) temp; abdomen mildly distended; abdominocentesis reveals serosanguinous fluid; string anchored under the base of the tongue; what test will confirm clinical suspision?
Compare glucose of peripheral blood to glucose of abdominal effusion
In BVD, what is the presentation of the fetus if infected at less than 125 days gestation vs more than 170 days gestation?
<125 d = early embryonic death, fetal death, abortion, congenital defects, mummification, OR persistently infected

Head tilt + CN deficits –> on the side of lesion
Conscious proprioceptive deficits + head pressing + depression –> intracranial problem
