For the last ten years, your state has had a mandatory vaccination program against
"pedunculated giblet disease" in fur-bearing turtles and the prevalence of this terrible
disease has decreased markedly.
How does this decrease in prevalence affect the predictive value positive (PVP) of the
best serologic test for pedunculated giblet disease?
A - PVP is affected by specificity, not prevalence
B - PVP depends on the number tested, not prevalence
C - PVP stays the same as prevalence decreases
D - PVP increases as prevalence decreases
E - PVP decreases as prevalence decreases
Give this one a try later!
E - PVP decreases as prevalence decreases
,Under what conditions may the technician's hands be under the path of a primary x-
ray beam when assisting in the radiology area?
A. When the x-ray beam is collimated
B. If a grid is used
C. When the animal is moving too much for a clear radiograph
D. If lead gloves are worn
E. Under no conditions

Two bucket-fed veal calves are depressed and stunted and have sticky feces coating
their hindquarters.
Fluid-splashing sounds are audible during auscultation over the left flank when a calf
,is drinking.
Passage of a stomach tube obtains a rancid-smelling liquid with a pH of 5.2 [N=5.9-
6.2]
Which one of the following choices is the most appropriate diagnosis?
A - Colibacillosis
B - Ruminal drinker
C - Vitamin E/Selenium deficiency
D - Enterotoxemia
E - Pica

A pig farm has several sick and dying adult pigs. Affected animals are
febrile and depressed.
Some seem constipated and others have diarrhea. A few are ataxic.
A necropsy on one of the dead pigs shows widespread petechial and
ecchymotic hemorrhages in the kidneys ("turkey egg kidneys"),
bladder, spleen, and larynx.
Which one of the following choices is the most likely diagnosis?
A. Anthrax
B. Postweaning multisystemic wasting syndrome
C. Mycoplasma hyopneumoniae
D. Glasserella parasuis (formerly Haemophilus parasuis)
E. Classical swine fever

A four-month-old calf from a small beef herd in Louisiana presents
with a fracture of the right metatarsus.
He was normal last night. The owner found the calf this morning after
rounding up the herd for deworming.
This is the fifth calf this season with fractured bones.
One had a vertebral fracture, two calves had humeral fractures, and
one other had a cannon bone fracture.
Which one of the following choices is the most likely problem in this
herd?
A. High dietary phosphorus
B. High dietary calcium
C. Low dietary protein
D. Low dietary copper
E. Hypovitamintosis D
Give this one a try later!
D. Low dietary copper
A nine-year-old male neutered German shepherd is presented with unchecked
bleeding from a cut on the gums above the right canine tooth. The owner relates that
the dog has lost weight and had an episode of collapse three days ago, but he
recovered.
On physical exam, the gums are pale with petechiae and ecchymotic hemorrhages.
