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

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

Prostaglandin followed by melengestrol acetate in 19 days - ANSWER Gonadotropin-
releasing hormone followed by prostaglandin in 15 days
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 - ANSWER Salvage to slaughter

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
2
,Mucosal disease
Pasturellosis
Mycoplasmosis - ANSWER Infectious bovine rhinotracheitis
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 - ANSWER Haemophilus parasuis
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 - ANSWER Cephalexin and prednisone
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
3
, 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 - ANSWER Administration of procaine penicillin G
intramuscularly
In a mare, a 30-day pregnancy is most likely to be detected on rectal examination by which
of the following?
Absence of ovarian follicles
Palpation of the chorionic vesicle
Palpation of the corpus luteum
Palpation of the fetus
Slipping the fetal membranes - ANSWER Palpation of the chorionic vesicle
a 12-year old male budgerigar is evaluated because of a two-week history of progressive
difficulty gripping with the right foot. The client reports that during the past three days, the
bird has stopped using the foot entirely but he still flies around the house daily. On physical
examination, mild coelomic distention is palpated. The bird is standing on his perch using the
left leg only. All toes of the right food are pointing downward with no gripping capability.
Which of the following is the most likely cause of the paralysis?
Chronic heavy metal toxicity
Previous trauma
Renal neoplasm
