1. A dog presents with acute vomiting, lethargy, and bloody diarrhea after exposure to trash. What
is the most likely cause?
A) Parvovirus infection
B) Chocolate toxicity
C) Dietary indiscretion
D) Heartworm disease
Answer: A
Rationale: Acute hemorrhagic diarrhea in a puppy is classic for canine parvovirus; rapid
identification prevents severe dehydration and death.
2. A horse presents with colic and tachycardia. Which diagnostic is most appropriate first?
A) Abdominal ultrasound
B) Blood glucose measurement
C) Physical exam and nasogastric tube
D) MRI
Answer: C
Rationale: Physical exam and nasogastric tube evaluation are primary for colic assessment;
imaging is secondary.
3. A cat shows sudden hindlimb paralysis after a fall. Which nerve is most likely affected?
A) Femoral nerve
, Page 3 of 133
B) Sciatic nerve
C) Median nerve
D) Radial nerve
Answer: B
Rationale: Sciatic nerve damage results in hindlimb paralysis and decreased sensation in cats.
4. During routine vaccination, a cow develops facial swelling and urticaria. Which is the most
appropriate immediate action?
A) Observe for 24 hours
B) Administer epinephrine and antihistamines
C) Continue vaccination on other cows
D) Euthanasia
Answer: B
Rationale: Signs indicate anaphylaxis; epinephrine is life-saving, antihistamines mitigate
reaction.
5. A dog ingests xylitol-containing gum and shows hypoglycemia. What is the best treatment?
A) Administer insulin
B) Intravenous dextrose
C) Oral activated charcoal
D) Fluid restriction
, Page 4 of 133
Answer: B
Rationale: Xylitol causes rapid insulin release; IV dextrose corrects hypoglycemia immediately.
6. A cow herd shows sudden abortions and fever. Which pathogen is most likely involved?
A) Brucella abortus
B) Escherichia coli
C) Staphylococcus aureus
D) Toxoplasma gondii
Answer: A
Rationale: Brucellosis commonly causes abortion in cattle; rapid diagnosis and containment are
essential.
7. During anesthesia, a dog becomes hypotensive and tachycardic. What is the most likely cause?
A) Vasodilation from anesthetics
B) Hypoglycemia
C) Pain stimulation
D) Hyperthermia
Answer: A
Rationale: Common anesthetics reduce vascular tone, causing hypotension; monitoring and
fluids correct the issue.
