Question 1
A litter of 6 week old kittens is being evaluated because of intermittent soft stools with
flecks of blood. The kittens are confined in an unsanitary cage. Two direct fecal
examinations show oocysts. Which of the following is the most appropriate therapy?
dichlorvos
fenbendazol
ivermectin
piperazine
sulfadimethoxine
CORRECT ANSWER
sulfadiemthoxine (Albon, for coccidiosis)
Question 2
On examination of the cranial nerves in a 3-year old female cat, the right pupil appears to
be larger than the left pupil. The right pupil shows no response when light is shone into
either eye. The left pupil constricts when light is shone into either eye. Mild ventrolateral
strabismus is noted in the right eye only. These findings are most consistent with a lesion
at which of the following locations?
left occipital cortex
right occipita cortex
right optic (II) nerve
right oculomotor (III) nerve

,right abducens (VI) nerve
CORRECT ANSWER
right oculomotor (III) nerve
Question 3
A 4-year old second-lactation Holstein cow that is 150 days in milk has been in anestrus
since calving. On palpation of the rectum, a cystic structure that is 3cm in diameter is
identified on the left ovary. Administration of which of the following is the most
appropriate initial treatment?
Follicle-stimulating hormone followed by gonadotropin-releasing hormone in 15 days
Gonadotropin-releasing hormone followed by prostaglandin in 15 days
Melengesterol acetate followed by prostaglandin in 19 days
Prostaglandin followed by melengestrol acetate in 19 days
CORRECT ANSWER
Gonadotropin-releasing hormone followed by prostaglandin in 15 days
Question 4
A 10-year-old commercial beef cow has had a gradually diminished appetite and
progressive weight loss over the past two months. Feces are dry and scanty. She continues
to drink water. Physical examination shows distention of the left paralumbar fossa and
ventral right abdominal wall. On rectal palpation, the rumen is full of firm ingesta and the
ventral sac extends to the right of midline (L-shaped). Which of the following is the most
appropriate next step?
Administration of bisthmuth subsalicylate with sucrose
Administraiton of magnesium hydroxide
Exploratory laparotomy

,Salvage to slaughter
Surgical creation of a rumen fistual
CORRECT ANSWER
Salvage to slaughter
Question 5
Fifteen percent to 20% of feedlot heifers that recently arrived from several auction
markets are anorectic. Physical examination of the heifers shows serous nasal and ocular
discharge, short explosive cough, and hyperemia of nasal mucosa. Which of the following
is the most likely diagnosis?
Atypical interstitial pneumonia
Infectious bovine rhinotracheitis
Mucosal disease
Pasturellosis
Mycoplasmosis
CORRECT ANSWER
Infectious bovine rhinotracheitis
Question 6
A group of 1000 5-week-old pigs has experienced a 2% death loss since weaning two
weeks ago. most of the deaths were sudden; however, approximately 3% of the pigs
showed clinical signs of lethargy, lameness, and labored breathing before dying.
Postmortem examination of an affected pig shows severe fibrinous pleuritis, pericarditis,
and peritonitis. Which of the following is the most likely causal organism?
Arcanobacterium suis

, Escheria coli
Haemophilus parasuis
Salmonella cholerasuis
Streptococcus suis
CORRECT ANSWER
Haemophilus parasuis
Question 7
A 9-week-old Rottweiler-mix puppy is beign evaluated because of an itchy rash around the
lips and eyelids. Temperature is 103.3*F. Physical examination shows swellign of the
muzzle, pruritic, exudative pustiles around the lips and eyelids, and swelling of the
submandibular lymph nodes bilaterally. Which of the following is the most appropriate
treatment?
Cephalexin and prednisone
Clindamycin and carprofen
Enrofloxcin and etodolac
Topical amitraz
Topical betamethasone
CORRECT ANSWER
Cephalexin and prednisone
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 occured 10 days ago. Rectal temperature is 104*F . During PE, the
cow is reluctant to move and periodically kicks at her abdomen. On rectal palpation, the
left kidney is grossly enlarged and has a smooth texture. When stimulated to urinate, the
