A 4 year old female Holstein cow is diagnosed with lactic
acidosis. If she survives the acute disease, she is at greatest
risk for which of the following conditions?
, Page 2 of 153
A) Cystitis
B) Mastitis
C) Metritis
D) Sole abscess
E) Uveitis ...... ANSWER ....... D) Sole abscess
Lactic acidosis (grain overload) in cattle leads to rumenitis
— inflammation and damage to the rumen wall. Once the
rumen epithelium is compromised:
- Bacteria (e.g., Fusobacterium necrophorum,
Arcanobacterium pyogenes) can enter the portal circulation.
- They form hepatic abscesses.
- Bacterial toxins and emboli from these abscesses or
rumenitis-associated endotoxemia then affect laminar
corium perfusion in the hooves.
- Result → Laminitis, which predisposes to sole
ulcers/abscesses and other claw horn lesions.
Which of the following is the most common clinical sign
associated with guttural pouch mycosis in the horse?
A) Corneal ulceration
B) Dysphagia
C) Epistaxis

D) Horner's syndrome
E) Paralysis of the facial (VII) nerve ...... ANSWER ....... C)
Epistaxis
A 3 year old Thoroughbred gelding has had lethargy and a
poor appetite for the past two weeks. Rectal temperature is
101.4 degrees F (38.6 degrees C), heart rate is 42 beats/min,
and respiratory rate is 16 breaths/min. Physical examination
shows mild depression, exposure keratitis of the right eye,
and a head tilt, with the poll displaced to the right. The
muzzle is deviated to the left, and the lower lip is flaccid and
dropping. Which of the following is the most appropriate
next step in establishing the diagnosis?
A) Electromyography
B) Endoscopic evaluation of the larynx
C) Evaluation of aspirate from the temporomandibular joint
D) Nerve conduction velocity tests
E) Skull radiography ...... ANSWER ....... A)
Electromyography
A 3 year old Afghan Hound dog has tachypnea and pleural
effusion. Thoracocentesis yields an opaque, pinkish white
fluid with a specific gravity of 1.020. Which of the following
methods is most accurate in confirming the diagnosis?
, Page 4 of 153
A) Comparing cholesterol and triglyceride content of the
effusion and the serum
B) Performing an ether clearance test on the effusion and
the serum
C) Performing cytologic examination to determine the
proportion of lymphocytes in the effusion
D) Performing ultrasonography of the thorax
E) Staining the effusion with Sudan stain to identify fat ......
ANSWER ....... Correct answer: A) Comparing
cholesterol and triglyceride content of the effusion and
the serum
Why: The description (opaque, pinkish-white pleural fluid;
SG ~1.020) is classic for chylothorax, to which Afghan
Hounds are predisposed. The most accurate confirmation is
to measure lipids:
Chylous effusion: Triglycerides in fluid > serum (often >100
mg/dL in dogs), and
Cholesterol:triglyceride ratio < 1 in the effusion.
Why not the others:
B) Ether clearance and E) Sudan stain: old, nonspecific fat
tests—can be misleading.
C) Cytology: Often lymphocyte-rich, but not definitive (can
shift with chronicity).
