A 10-year-old commercial beef cow has had a gradually diminished appetite and
Y
progressive weight loss over the past two months. Feces are dry and scanty. She
L
continues to drink water. Physical examination shows distention of the left
F
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
, 2
Exploratory laparotomy
Salvage to slaughter
Surgical creation of a rumen fistual - ANS Salvage to slaughter
R
A 12-week-old kitten is evaluated on the advice of the client's family physician
E
because regional lmyphadenitis caused by Bartonella hensalae infetion was
H
diagnosed in their 8-year-old daughter two days ago. The kitten was acquired
from a shelter three weeks ago. There are no other cats or dogs in the household.
G
While awaiting the results of serologic tests for B henselae infection in the kitten,
I

H
transmission of infection to other family members?
G
Bite wounds from the kitten
N
Contact with the kitten's feces
I
Contact with the kitten's saliva
Y
Scratch wounds from the kitten - ANS Scratch wounds from the kitten

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
, 3
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
R
Previous trauma
E
Renal neoplasm
H
Right-sided intervertebral disk disease
Severe arthritis - ANS Renal neoplasm
IG
A 12-year old spayed female Persian cat is evaluated because of a one-week
H
history of anorexia, vomiting, polyuria, and polydipsia. BCS is 3/9. PE shows
G
lethargy and enlarged, irregular kidneys bilaterally. Serum study shows: BUN
32.18 (N 10-30) Creat 2.54 (N 0.5-2) Gluc 110 (N 65-120) Which of the following is
N
the most likely cause of these findings?
YI
Bacterial cystitis
L
Chronic interstitial nephritis
F
Diabetes mellitus
Polycistic kidney disease
Transitional cell carcinoma - ANS Polycistic kidney disease
A 12-year-old spayed female Siamese cat is evaluated because of the acute onset
of blindness. Physical examination shows dilated pupils bilaterally; menace
, 4
responses and pupillary light reflexes are absent. The pupils constrict after
topical application of pilocarpine. Indirect ophthalmoscopic exam discloses areas
of retinal hemorrhage. Administration of which of the following is the most
appropriate treatment?
Amlodipine
ER
H
Mannitol
Prednisolone
G
Tacrolimus
I
Timolol - ANS Amlodipine
GH
A 13-year-old cat has a large, firm mass of the third mammary gland on the right
side. Which of the following represents the likelihood that this tumor is
N
malignant?
YI
10%, 25%. 40%, 60%, 90% - ANS 90%
FL
A 14-year-old cat has been occasionally "walking into things" for the past week.
The cat has hyperthyroidism that has been treated with methimazole for the past
year. PE, chemistry, and measurement of serum thyroxine (T4) concentration
performed two weeks ago showed no abnormalities. Ophthalmic exam at this
time shows bilaterally detached retinas. Which of the following is the most
appropriate next step in establishing the cause of this cat's condition?
