biopsy of the regions reveals collagen degeneration and granulomatous inflammation
with eosinophils. Which of the following is not a reasonable treatment option for this

Rufus, a 10 year-old male neutered Labrador retriever, was presented to your hospital
for acute abdominal pain, vomiting, and distended abdomen. The owners had a large
family gathering for Thanksgiving and Rufus spent a significant portion of the day
begging for table scraps from the little nieces and nephews; and the owners also noted
that their grandmother spent a lot of time feeding the dog as well. You've known Rufus
for a long time and you've never seen him so lethargic. You are immediately suspicious
of pancreatitis. His PLI snap test is a strong positive, and his complete blood count and
chemistry panel show the following:
, CBC-HCT 31 (36-50%)
WBC 21,800 (7,000-17,000/uL)
PLT 23,000 (200,000-900,000/uL)
CHEM-BUN 20 (10-22 mg/dL) CREA 2.1 (0.5-2.2 mg/dL) TP 6.3 (5.5-7.3 g/dL) ALT 32
(3-33 IU/L)ALP 70 (10-80 IU/L)GLU 120 (60-125 mg/dL)Amylase- 2300 (337-1469
U/L)Lipase 1410 (138-755 U/L)
Based on these results, - ANSWERSPT (prothrombin time), PTT (activated partial
thromboplastin time), FDP (fibrin degradation product)
Diseases that cause severe inflammation can induce disseminated intravascular
coagulation (DIC) complex. The severe inflammation from pancreatitis can cause
massive endothelial injury, resulting in vasculitis.
A horse presents with vestibular signs. Which of the following findings allows the
clinician to differentiate between central vestibular and peripheral vestibular disease? -
ANSWERSProprioceptive deficits
A valuable Merino ram which has been on a high protein diet is brought to you because
it has scabs on the mucocutaneous junction of the prepuce that were only recently
noticed. The owner checked him closely when the ram appeared to experience pain
upon attempting to breed, and had become reluctant to breed. It is the only animal
affected, and the lambs, ewes, and 2 other rams appear normal. When you examine the
lesions you find painful ulcers under the foul smelling scabs. Which of the following
choices is the treatment of choice? - ANSWERSIsolation, reduce the dietary protein,
and administer penicillin
The high protein diet allows C. renale to proliferate and split urea to form ammonia,
which ulcerates the area.
A dairy cow is mounting another cow. Which is in heat? - ANSWERSThe cow that is
mounted
This gives off hormonal cues that other cows may pick up on and lead to them mounting
her irrespective of whether the cow doing the mounting is in heat.
Ivermectin is used to treat Onchocerca microfilariae. What is used to treat the adult
helminths? - ANSWERSThere is no effective treatment against the adults
A 12-year old mare presents to you as a "windsucker". Why is pneumovagina in mares
of medical concern? - ANSWERSIt heavily predisposes to vaginitis and endometritis
. Aspiration of air leads to contamination, and pneumovagina is the most common
cause of genital infections in the horse. Pneumovagina is a common cause of infertility
