1. A 6-year-old Thoroughbred gelding was involved in a motor vehicle
collision while riding in a trailer three weeks ago. Physical examination shows
heling superficial abrasions on the face. A photograph is shown. Injury to which of
the following nerves is the most likely underlying causes of these findings?
A) Left Facial (VII) Nerve
B) Right Facial (VII) Nerve
C) Left Trigeminal (V) Nerve
D) Right Trigeminal (V) Nerve
E) Left infraorbital nerve
F) Right Infraorbital Nerve: B) Right Facial (VII) Nerve
2. In cases of pyothorax in cats, what type of microorganisms are most
frequently cultured from pleural fluid?
A) Chlamydiae
B) Mycoplasmas
C) Obligate anaerobes
D) Spirochetes
E) Yeasts: C) Obligate anaerobes

3. A 6-year-old male Cocker Spaniel has recurrent otitis externa. Microscopic
examination of a smear of purulent ear discharge shows large numbers of rod
shaped bacteria. What is the most likely causative organism?
A) Escheria coli
B) Klebsiella spp
C) Pasturella multocida
D) Pseudomonas aeruginosa
E) Staphylococcus intermedius: D) Pseudomonas aeruginosa
4. An 82-lb (37 kg) 8-year-old MN German Shepherd mix is being evaluated
for a 2 month history of decreased exercise tolerance. The client reports that the
dog had two episodes of profound weakness on walks during the past week. The
dog seems comfortable at home but his "heart is always racing." Two years ago the
dog was diagnosed by another vet with hypothyroidism and prescribed oral
levothyroxine 0.8 mg twice daily. Dosage was reevaluated one month after
initiation and was determined to be appropriate. Appetite, urination, and bowel
movements are normal. BCS is 6/9. Temp 101.2 F and HR 180 bpm. The dog is
panting. Pulse deficits are occuring 3-5x/min. No other abnormalities are noted.
CBC, serum chemistry, and urinalysis are WNL. Which of the following is the
most likely cause of episodic weakness in this dog?
A) Decreased cardiac output
B) Electrolyte imbalance
C) Neurogenic weakness
D) osteoarthritis
E) ventilation-perfusion mismatch: A) Decreased Cardiac Output
5. Fifteen of a group of 200, 7-month old feedlot calves are lame. The calves
arrived at the feedlot approximately 1 month ago, and one week later 40 of the
,3|Page
animals developed pneumonia. These calves were treated with oxytetracycline, and
pneumonia appeared to resolve. On Physical examination, the affected calves have
swellings in the carpi, tarsi, and stifles with distension of associated tendon sheaths
and a stiff gait. Two calves are euthanized. Postmorten examination shows
fibrinous pleuritis and papillary muscle necrosis.
Which of the following organisms is the most likely cause of these agents?
A) Arcanobacterium (Actinomyces) pyogenes B)Histophilus somni
(Haemophilus somnus)
C) Mannheima (Pasturella) haemolytica
D) Pasturella multocida
E) Salmonella typhimurium: B) Histophilus somni
6. A 2-year old spayed female indoor/outdoor Singapura cat has had several
facial pruritis for the past two weeks. Vaccinations are up-to-date and the cat is on
a monthly regimen of topical imidaclorid. Examination of the skin shows linear
ulcers along the ventral aspects of both mandibles and miliary scabs on the ventral
and lateral aspects of the neck. The remainder of the dermis appears normal. Deep
and surface skin scrapings and dermatophyte culture are negative. Which of the
following is the most appropriate next diagnostic step.
A) Serum Allergy Testing
B) Thyroid function testing
C) Trial of hypoallergenic diet
D) Trial of IM methylprednisolone
E) Trial of intramuscular cyclosporine: C) Trial of hypoallergenic diet.

7. A 9-month-old intact male Siberian Husky dog is being evaluated because of
a cough of 2 week duration. These lesions at the carina are seen on bronchoscopic
exam. Which of the following is the most appropriate pharmacotherapy?
A) Amoxicillin
B) Chlorpheniramine
C) Dextromethorphan
D) Ivermectin
E) Prednisone: D) Ivermectin
8. A 5-year old Simmental cow who is used as a donor for embryo transfer is
evaluated because of the acute onset of anorexia and lethargy. She has been
flushed six times; the most recent flushing occurred 10 days ago. Rectal
temperature is 104.0 F. During physical exam the cow is reluctant to moce and
periodically kicks at her abdomen. ON rectal palpation the left kidney is grossly
enlarged and has a smoot texture. When stimulated to urinate, the urine is grossly
hematuric; numerous blood clots and fibrin are present. Which of the following is
the most appropriate treatment?
A) administration of gentamicin intravenously
B) Administration of procaine penicillin G intramuscularly
C) Long-term catheterization of the bladder
D) Surgical removal of the enlarged kidney
E) No treatment is indicated.: B) Administration of
procaine penicillin G intramuscularly
9. A 13 year old cat has a large, firm mass of the third mammary gland on the
right side. Which of the following represents the likelihood that this tumor is
malignant A) 10% B) 25% C) 40%
