Question 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
CORRECT ANSWER
B) Right Facial (VII) Nerve
Question 2

from pleural fluid?
A) Chlamydiae
B) Mycoplasmas
C) Obligate anaerobes
D) Spirochetes
E) Yeasts
CORRECT ANSWER

, C) Obligate anaerobes
Question 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
CORRECT ANSWER
D) Pseudomonas aeruginosa
Question 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

CORRECT ANSWER
A) Decreased Cardiac Output
Question 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 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
CORRECT ANSWER
B) Histophilus somni
Question 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

@THE STUDY VAULT
, B) Thyroid function testing
C) Trial of hypoallergenic diet
D) Trial of IM methylprednisolone
E) Trial of intramuscular cyclosporine
CORRECT ANSWER
C) Trial of hypoallergenic diet.
Question 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
CORRECT ANSWER
D) Ivermectin
Question 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
