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.

treatment?
,Follicle-stimulating hormone followed by gonadotropin-releasing
hormone 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

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
,●● 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.
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 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?
