◉ 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 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

hormone in 15 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.

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

submandibular lymph nodes bilaterally. Which of the following is the
most appropriate treatment?

Topical amitraz
Topical betamethasone
Answer: Cephalexin and prednisone
