In dermatology, what is the difference between a papule and a macule?
A papule is a small, solid elevation of the skin up to 1cm in diameter (i.e., a pimple, but without pus [which would make it a pustule]); a macule is a circumscribed, nonpalpable spot of skin pigmentation up to 1cm in diameter (i.e., a freckle)
In a dog or cat, in which direction should the hindlimb be manipulated to minimize the risk of sciatic nerve damage when placing an intraosseous needle in the proximal femur?
The hindlimb is rotated internally and adducted, to widen access to the trochanteric fossa and reduce the risk of sciatic nerve damage
Name 3 types of transfusion reactions.
1) anaphylactic;

3) delayed hemolytic (development of anti-erythrocyte antibodies);
4) febrile/bacterial contaminant;
5) volume overload;
6) citrate toxicosis;
7) in vitro hemolytic;

A male lizard is presented for evaluation of recent-onset swelling of the ventral tailbase, adjacent and caudal to the cloacal opening. What is the most likely diagnosis?
Normal enlargement of the hemipenes with sexual maturity, or abnormal debris accumulation (seminal plugs)
Which hormone does the corpus luteum produce?
Progesterone
A high-producing dairy cow that freshened three weeks ago is off feed. On physical exam her heart and respiratory rates are within normal limits. T=101.2°F (38.4°C) [N=100.4–102.8°F (38.0–39.3°C)]
There is decreased rumen motility and a urine test for ketone bodies is positive. There is no evidence of mastitis and the uterus is clear of infection.
On the left side, a high-pitched musical “ping” is audible via stethoscope during percussion over the ribs on a line between the elbow and tuber coxae (hip).
What acid-base abnormality is most likely in this cow?
Respiratory alkalosis -
Metabolic alkalosis -
Depends on severity of displacement -
Metabolic acidosis -
Respiratory acidosis -
Metabolic alkalosis -
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. There is tachycardia and a palpable cranial abdominal mass.
A coagulation profile shows the following:
Thrombocytes= 82,533 per microliter. [N=200,000-900,000]
Buccal mucosal bleeding time (BMBT), increased
Activated partial thromboplastin time (aPTT), increased
Prothrombin time (PT), increased
Fibrin degradation products (FDPs), increased
What disorder of coagulation best fits this pattern?
Disseminated intravascular coagulation -
Idiopathic thrombocytopenia -
Von Willebrand’s disease -
Hepatic insufficiency -
Anticoagulant rodenticide toxicity -
Disseminated intravascular coagulation -
A practice is using an FeLV test with a sensitivity of 90% and a specificity of 95%.
Assuming the prevalence of feline leukemia in the area is 5%, what is the predictive value negative (PVN) of the test?
75% -
55% -
88% -
45% -
99% -
99%
A four-year-old Rat Terrier is presented with a three day history of progressive stumbling and falling.
Physical exam reveals a right head tilt, left sided hypermetria, generalized ataxia and vertical nystagmus.
Which one of the following choices is at the top of the differential list?
Ascending and descending myelomalacia -
Granulomatous meningoencephalitis
Fibrocartilagenous embolism -
Central pontine myelinolysis -
Amyotrophic lateralizing sclerosis -
- Granulomatous meningoencephalitis
The coagulation factors are numbered I to XIII. However, there are only 12. Which factor does not exist?
Factor VI
What is the main antidote for acetaminophen-induced methemoglobinemia in cats?
N-acetylcysteine (Mucumyst). S-adenosyl methionine (SAMe) also may be strongly beneficial
What is the timing of the murmur caused by aortic valve insufficiency?
Diastolic
In birds, dysfunction of which body system is most likely to cause green urates?
Hepatic. Green, bile-stained urates may be observed in feces during liver disease. Birds lack biliverdin reductase and form biliverdin instead of bilirubin as the primary breakdown product of heme
Hypoadrenocorticism is commonly called:
Addison’s disease
Two eight-week old calves are presented down and extremely weak.
They are depressed and lying in pools of foul-smelling brown diarrhea with a small amount of blood.
Another calf died suddenly the previous night with no prior signs.
The down calves are dehydrated, with rectal temperatures of 105.2° and 105.6° F (40.7° – 40.9° C) [N=101.5°-103.5°F, N=37.8°-39.7° C], respectively.
What is the treatment plan?
A.) IV fluids; NSAIDS; frequent milk feedings -
B.) Cull sick calves; prophylactic oxytetracycline in feed for well animals -
C.) Isolate sick calves; oral electrolytes -
D.) Corticosteroids; amprolium in water; rumensin in feed -
E.) Immunize calves and adult cattle with MLV vaccine; probiotics for sick calves -
IV fluids; NSAIDS; frequent milk feedings
At what age do a cow’s permanent 4th incisors begin to erupt in the mandible?
3 years -
5-6 years -
2 to 2.5 years -

7-8 years -
3.5 to 4 years
A two-year-old Angus cow is presented with weakness of the hind limbs and a staggering gait.
On physical exam, the heart rate and respiratory rate are slow and irregular, and the pupils are dilated.
The cow’s breath and urine smell like the odor of mouse urine.
Suddenly the cow’s pulse becomes rapid and thready, she collapses, and dies of apparent respiratory failure.
