WITH VERIFIED SOLUTIONS RATED A.
A mare is presented with a history of intermittent lameness in the right fore
involving a shortened stride and occasional stumbling.
She relieves pain by pointing the affected foot with the heel off the ground. A
flexion test of the distal right forelimb exacerbates the lameness
temporarily.
Which one of the following choices is the most likely diagnosis?
A - Laminitis
B - Caudal heel pain
C - Villonodular synovitis
D - Pedal osteitis
E - Sidebone
B - Caudal heel pain
A four-year-old male, neutered cat is presented with a history of severe
lethargy and inappetance.
The cats mucous membranes are extremely pale and his PCV at
presentation is 9%. [Normal=30-45%]
A blood transfusion is indicated.
Which one of the following choices best explains the rationale for blood
typing prior to transfusion in cats?
A - Cats have naturally-occurring antibodies against the blood group antigen
they lack
B - Blood typing is not necessary. Cats are universal receivers and can
receive any blood type
C - Cats that are negative for DEA 1.1 are more likely to have a reaction to
DEA 1.1 positive blood
D - If donor is Type A, it is a universal donor and recipient typing is not
,needed
E - Blood typing will determine if recipient cat is Rh factor negative or Rh
positive
A - Cats have naturally-occurring antibodies against the blood group antigen
they lack
NAVLE® Question of the Day:
A commercial turkey operation experiences an outbreak of disease in 40%
of its 12-16 week old birds. Typically affected birds show only depression,
then death.
Some animals appear weak, recumbent with one leg forward and one leg
back.
On necropsy, diffuse or nodular lymphoid tumors are visible in various
organs, particularly the liver, and spleen. Two affected birds have distorted
pupils.
What is the diagnosis?
A - Viral hepatitis of turkeys
B - Newcastle disease
C - Marek's disease
D - Infectious bursal disease
E - Histomoniasis
C - Marek's disease
Many hens in a large backyard flock recently became ill after the owner

They have poor appetite and act depressed. Some affected birds have
watery green diarrhea and swelling of the head and neck.
A few have paralyzed legs and wings, twisted necks, are circling, and have
tremors or clonic spasms.
Birds are not laying well and some eggs are misshapen with watery
, albumen. Many of the sickest birds have died.
Necropsy of a dead chicken shows petechial hemorrhages on the mucosal
surface of the proventriculus and gizzard (left).
What should be done next to address this problem?
A - Increase poultry house temperatures to reduce morbidity
B - Disinfect housing with phenolic compounds, barrier precautions for staff
C - Treat all affected chickens with amprolium
D - Cull affected birds and vaccinate the remainder
E - Report outbreak to regulatory authorities
E - Report outbreak to regulatory authorities
Which one of the following hormones can induce neoplastic transformation
of hypertrophied mammary tissue in cats?
A - Oxytocin
B - Progesterone
C - Estrogen
D - Testosterone
E - Prolactin
B - Progesterone
Which one of the following organisms transmits the causative agent of
blackhead disease in turkeys?
A - Heterakis gallinarum
B - Ascardia galli
C - Capillaria spp
D - Eimeria spp
E - Raillietina spp
A - Heterakis gallinarum
Which one of the following would be the best way to prevent a vibriosis
abortion storm in ewes?
