TESTED AND GRADED A+
A nursery barn manager finds a live pig in the condition shown (lateral
recumbency, paddling) in the photograph (image 5506) at 2:00 PM. This is the
only pig he has observed with this problem. The pig appeared clinically healthy
at 10:00 AM. Which of the following is the most likely cause of this condition?
A) Carbon monoxide poisoning
B) Porcine reproductive and respiratory syndrome
C) Streptococcal meningitis
D) Swine influenza
E) Vomitoxin --ANSWER--C) Streptococcal meningitis
A 2 year old corn snake is evaluated because its eyes have been dry, dull, and
"wrinkled" since the snake shed its skin one week ago. Physical examination
shows retained spectacles. Which of the following is the most appropriate
immediate management of this snake?
A) Administer antibiotics systemically
B) Administer corticosteroids topically
C) Provide a bowl of water for the snake to soak in
D) Reevaluate after the next shedding of skin --ANSWER--C) Provide a bowl
of water for the snake to soak in

,In the dog, which of the following is the most effective anthelmintic agent
against tapeworms of the genera Dipylidium and Taenia?
A) Diethylcarbamazine
B) Fenbendazole
C) Piperazine
D) Praziquantel
E) Pyrantel pamoate --ANSWER--D) Praziquantel
A 2 year old intact male cat is being evaluated because of a respiratory tract
infection. On physical examination, salivation and ulceration of the tongue and
hard palate are noted. A radiograph shows interstitial pneumonia. Which of the
following is the most likely diagnosis?
A) Feline calicivirus infection
B) Feline herpesvirus infection
C) Feline panleukopenia virus infection
D) Feline pneumonitis
E) Feline reovirus infection --ANSWER--A) Feline calicivirus infection
A 5 year old castrated male cat is present for the acute onset of hindlimb
paresis, pain, absence of femoral pulses, and cold, firm musculature. Which of
the following is best for confirming the cause of the suspected diagnosis?
A) Computed tomography (CT) scan
Page 2 of 106
,B) Echocardiography
C) Magnetic resonance imaging (MRI)
D) Myelography
E) Spinal radiography --ANSWER--B) Echocardiography
Which of the following is the most common indication for extirpation of the eye
in bovines?
A) Infectious keratoconjunctivitis
B) Panophthalmitis
C) Squamous cell carcinoma
D) Trauma with irreparable damage
E) Trauma with loss of globe contents --ANSWER--C) Squamous cell
carcinoma
Which of the following is the most appropriate class of antibiotics for the
treatment of bite wound abscesses in cats?
A) Aminoglycosides
B) Beta-lactam drugs
C) Chloramphenicols
D) Fluoroquinolones
E) Tetracyclines --ANSWER--B) Beta-lactam drugs

, A 14 year old neutered male domestic longhaired cat is evaluated because of a 3
month history of decreased activity level. The cat has neem an indoor/outdoor
cat during the past year. Body condition score is 5/9. Temperature is 100.6
degrees F (38.1 degrees C), heart rate is 164 beats/min, and respiratory rate is
36 breaths/min. On physical examination, capillary refill time is 1 second.
Palpation of the thyroid glands shows no abnormalities. Thoracic auscultation
discloses a grade III/VI sternal murmur and a gallop rhythm. Which of the
following is most likely present in this cat?
A) Dilated cardiomyopathy
B) Dysplasia of the tricuspid valve
C) Hypertrophic cardiomyopahty
D) Left-to-right shunt
E) Systolic anterior motion of the mitral valve --ANSWER-- Correct
answer: C) Hypertrophic cardiomyopathy
Why:A geriatric cat with a new grade III/VI sternal systolic murmur and a
gallop rhythm (S3/S4) most strongly suggests HCM with diastolic dysfunction.
Normal thyroid palpation makes hyperthyroid-associated cardiomyopathy less
likely. Congenital lesions (e.g., left-to-right shunts, tricuspid dysplasia) are
unlikely to present de novo at 14 years. DCM is rare in cats today (post-taurine
era).
Note on option E:Systolic anterior motion (SAM) of the mitral valve is
commonly present in HCM cats (especially with dynamic LV outflow tract
obstruction) and explains a left sternal systolic murmur, but it's a
mechanism/finding within HCM, not the primary diagnosis. Given mixed
answer types, choose HCM (C).
