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: sulfadiemthoxine (Albon, for coccidiosis)
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: right oculomotor (III) nerve
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
, NAVLE practice test
Prostaglandin followed by melengestrol acetate in 19 days: Gonadotropin-
releasing hormone followed by prostaglandin in 15 days
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: Salvage to slaughter
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: Infectious bovine rhinotracheitis
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
, NAVLE practice test
Escheria coli
Haemophilus parasuis
Salmonella cholerasuis
Streptococcus suis: Haemophilus parasuis
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: Cephalexin and prednisone
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
urine is grossly hematuric; numerous blood clots and fibrin are present.
Which of the following is the most appropriate treatment?
Administration of gentamicin intravenously
Administration of procaine penicillin G intramuscularly
Long-term catheterization of the bladder
Surgical removal of the enlarged kidney
No treatment is indicated: Administration of procaine penicillin G intramuscularly
9. In a mare, a 30-day pregnancy is most likely to be detected on rectal
examination by which of the following?
