NAVLE Prep Questions With Correct
Answers.
A person calls to to say she adopted a friend's dog and requests a copy of the dog's medical record and
radiographs. The former owner is a client at your clinic. Which one of the following choices is the most
appropriate action to take?
A - Require original owner consent or court order to release information
B - Give caller a copy of medical record only
C - Give caller a copy of medical record and radiographs
D - After physical exam, start a new medical record documenting previous issues
E - Give a summarized record with personal identifiers (vet, owner names) blocked out - answer✔A
According to the AVMA's Principles of Veterinary Medical Ethics (2008 revision)
"Ethically, the information within veterinary medical records is considered privileged and confidential. It
must not be released except by court order or consent of the owner of the patient. Veterinarians should
secure a written release to document that request."
A 5 year old domestic short-haired spayed female cat is presented with the complaints of anorexia,
chronic vomiting, and weight loss.
Physical examination reveals icterus, dehydration, and fever. Thickened small intestinal loops are
appreciated with abdominal palpation, and serum biochemistry shows increased bilirubin and liver
enzymes.

The cat is diagnosed with extrahepatic biliary obstruction with accompanying cholangitis and
inflammatory bowel disease. Which one of the following normal anatomic features may predispose cats
to this triad of diseases?
A - Narrowing of the duodenum distal to the entry of the common bile and pancreatic ducts
B - Common opening of the pancreatic and common bile ducts into duodenum
C - Enlarged duodenal papilla in comparison to other species
D - Decreased proportion of alpha-smooth muscle actin in muscle fibers of the wall of the gall bladder in
cats
E - Decreased diameter and increa - answer✔B
In cats, there is a common opening of the pancreatic and common bile ducts into the duodenum. It is
thought that this may predispose them to ascending cholangitis and pancreatitis after vomiting
associated with inflammatory bowel disease, resulting in extrahepatic biliary obstruction.
Other possible etiologies of EHBO include neoplasia, biliary stricture, duodenal obstruction,
diaphragmatic hernia, and parasitic infection.
In all cases, there is a lack of bile entry into the intestinal tract, leading to decreased absorption of fat
and fat soluble vitamins such as vitamin K, potentially resulting in coagulopathies.
Except in transient cases that are related to acute pancreatitis, surgical intervention to relieve the
obstruction is required as well as appropriate supportive care, antimicrobial treatment, and vitamin K
administration.
Most of a litter of European wild boar at a zoological park have died. The surviving piglets are in lateral
recumbency with a frothy nasal discharge. Necropsy of the piglets reveals pulmonary edema and
copious fluid in the trachea and bronchi along with grayish- white necrotic foci on the myocardium.
Which one of the following diseases is the most likely diagnosis?
A - Edema disease
B - Encephalomyocarditis

C - Glasser's Disease
D - Porcine Respiratory and Reproductive Syndrome
E - Pseudorabies - answer✔B
Encephalomyocarditis virus (EMCV) is caused by a cardiovirus in the family picornaviridae. Confusingly,
the virus is named for its effects on mice.
Think of rodents and exotic zoo mammals with EMCV. Pig-to-pig contact, contamination of swine feed
and water by rodents or ingestion of dead rodents may cause disease. See pulmonary edema and
copious transudate in the respiratory tract, causing cardiac failure. Zoo outbreaks of EMCV have
included lions, African elephants, rhinos, hippos, sloths, llamas, antelope and nonhuman primates. An
outbreak of lion deaths at a Florida zoo in the USA occurred after feeding them the carcass of an African
elephant that had died of EMCV.
Edema disease is a neurologic disease caused by a hemolytic Escherichia coli producing Shiga toxin e2
and F18 pili resulting in high mortality in recently-weaned pigs.
Glasser's Disease, caused by Hemophilus parasuis is usually an acute disease of 6 to 8 week-old pigs
which causes fibrinous arthritis, polyserositis, and meningitis.
Porcine Reproductive and Respiratory Syndrome (PRRS), is an arterivirus causing reproductive failure
and post-weaning respiratory disease.
What is the main mode of transmission for feline leukemia virus?
A - Aerosol transmission
B - Shedding of virus via feces
C - Fomite transmission
D - Shedding of virus via saliva - answer✔D
The correct answer is shedding of virus via saliva. The main mode of transmission is via saliva. It requires
prolonged, close contact. Cats may shed the virus for months to years. Transmission may also occur
through reuse of instruments and blood. Virus is shed in saliva, tears, urine, and feces.

You are working with a farmer who is having trouble with calves between the age of 2 weeks and 6
months. They are alert, but weak, dyspneic and die suddenly. On necropsy they have pale cardiac and
skeletal muscles. What is the farmer's problem?
A - Copper deficiency
B - Sorghum toxicity
C - Lightning strike
D - Selenium deficiency - answer✔D
The correct answer is selenium deficiency. The pale muscle and clinical signs are classic for vitamin E and
selenium deficiency. This is important to remember! Other things that should be on your differential list
for this case include cardiotoxic plants.
A 6-year old intact male domestic short haired cat presents with acute onset exophthalmos of the right
eye in the past 2 days. He is painful on palpation around his eye and head. The eye can be retropulsed
with minimal resistance. He has not been eating in the past day and has a rectal temperature of 103.4F
(39.7 C). What is the most likely diagnosis?
A - Orbital neoplasia
B - Retrobulbar abscess
C - Anterior uveitis
D - Glaucoma - answer✔B
The answer is a retrobulbar abscess. Acute, painful exophthalmos is usually due to retrobulbar
abscessation. These lesions are usually painful and may be swollen. These animals are frequently
systemically ill with fever and leukocytosis. Causes of retrobulbar abscesses include penetrating wounds,
foreign bodies, spread from dental or sinus infection, and hematogenous spread. Glaucoma does not
cause exophthalmos, although, chronically it can cause buphthalmos which may appear similar. Anterior
uveitis also does not cause exophthalmos.
