CERTIFICATION PREPARATION
1. A 14-year-old, 450-kg Quarter Horse gelding presents with acute onset of severe abdominal
pain. The horse is pawing, looking at its flank, and has a heart rate of 68 bpm. On rectal
examination, you palpate a gas-distended large colon that feels doughy and is not actively
contracting. What is the most appropriate initial step in managing this patient?
A. Administer flunixin meglumine and wait for improvement.
B. Perform an immediate nasogastric intubation.
C. Begin a continuous rate infusion of lidocaine.
D. Refer the horse for exploratory laparotomy.
Correct Answer: B. Perform an immediate nasogastric intubation.
Rationale: Nasogastric intubation is a critical and immediate step in any acute colic presentation. It
allows for the decompression of stomach gas and fluid, which can alleviate pain and prevent gastric
rupture. While pain relief (A) and further diagnostics are important, relieving gastric distension takes
priority. Lidocaine (C) can be helpful for ileus but is not the first step. Surgery (D) may be necessary,
but medical management and stabilization are attempted initially.
2. A veterinary technician is preparing to administer a vaccine to a fractious cat. The cat is hissing
and attempting to swat. Which of the following restraint techniques is considered the safest and
most effective for this scenario?
A. Full-body restraint using a towel wrap, also known as a "kitty burrito."
B. Scruffing the cat while extending the hind legs.
C. Using an Elizabethan collar and a cat bag.
D. Chemical restraint with intramuscular ketamine and dexmedetomidine.
Correct Answer: D. Chemical restraint with intramuscular ketamine and dexmedetomidine.
Rationale: For a fractious cat where safety is a primary concern, chemical restraint is often the safest
and least stressful option for both the animal and handler. A combination of ketamine and a sedative
like dexmedetomidine provides effective immobilization. Physical restraint methods (A, B, C) can
increase the cat's fear and aggression, posing a significant bite/scratch risk and are less effective.
3. A 7-year-old Labrador Retriever presents with a history of progressive hind limb weakness,
difficulty rising, and muscle atrophy. On physical examination, conscious proprioception is delayed
in both hind limbs, and a crossed extensor reflex is noted. Where is the most likely location of the
lesion?
,A. C1-C5 spinal cord segments.
B. L4-S3 spinal cord segments.
C. T3-L3 spinal cord segments.
D. Neuromuscular junction.
Correct Answer: C. T3-L3 spinal cord segments.
Rationale: Upper motor neuron (UMN) signs such as delayed proprioception and crossed extensor
reflexes in the hind limbs, without forelimb involvement, localize a lesion to the T3-L3 spinal cord
segments. C1-C5 (A) would cause UMN signs in all four limbs. L4-S3 (B) would cause lower motor
neuron (LMN) signs in the hind limbs. A neuromuscular junction disorder (D) would present with
generalized weakness and exercise intolerance, not asymmetric UMN signs.
4. A horse is receiving a continuous rate infusion (CRI) of lidocaine for the management of
postoperative ileus. Which of the following clinical signs should the veterinary nurse monitor for as
the most common early indicator of lidocaine toxicity in this species?
A. Seizures and nystagmus.
B. Tachycardia and hypertension.
C. Hypersalivation and muscle fasciculations.
D. Respiratory depression and bradycardia.
Correct Answer: C. Hypersalivation and muscle fasciculations.
Rationale: In horses, the earliest signs of lidocaine toxicity are often neurologic, manifesting as
hypersalivation, muscle fasciculations, and ataxia. As toxicity progresses, it can lead to seizures and
cardiovascular depression. Tachycardia (B) is not a primary early sign. Respiratory depression (D) is a
late and severe sign of toxicity.
5. When performing a dental float on a sedated horse, the veterinary technician notices that the
horse's respiratory rate has dropped from 16 to 6 breaths per minute, and mucous membranes are
pale. What is the most likely cause of this complication?
A. Anaphylaxis to the sedative drug.
B. Aspiration pneumonia from dental debris.
C. Laryngospasm from the speculum.
D. Endotracheal tube obstruction.
Correct Answer: D. Endotracheal tube obstruction.
Rationale: A dental float is typically performed under general anesthesia with the horse intubated. A
sudden decrease in respiratory rate and pale mucous membranes is highly suggestive of an airway
obstruction. The most common causes are a blocked endotracheal tube (from secretions or a kink), a
dislodged tube, or a malpositioned tube leading to a one-lung or no-lung ventilation. This is a life-
threatening emergency requiring immediate assessment and correction of the tube.
,6. A 2-year-old cat is presented with a history of coughing and wheezing that is unresponsive to
antibiotics. Radiographs reveal a diffuse bronchial pattern. A fecal flotation is positive for a few
ova. Which parasitic infection is most likely the underlying cause of this respiratory condition?
A. Toxocara cati
B. Aelurostrongylus abstrusus
C. Dirofilaria immitis
D. Ancylostoma tubaeforme
Correct Answer: B. Aelurostrongylus abstrusus
Rationale: Aelurostrongylus abstrusus, the feline lungworm, causes respiratory signs such as
coughing and wheezing, often with a diffuse bronchial pattern on radiographs. It is a common cause
of respiratory disease in cats that may be refractory to antibiotics. While Toxocara cati (A) and
hookworms (D) can have a pulmonary migratory phase, they rarely cause this specific clinical picture.
Heartworm (C) is more common in dogs and typically presents with different radiographic findings.
7. A mixed-breed dog presents with a painful, swollen right hock. The owner reports the dog was
running in a field and abruptly yelped. You suspect a fracture. What is the most critical initial
diagnostic step to confirm this suspicion?
A. Palpating for crepitus.
B. Taking a dorsoplantar radiograph.
C. Performing a neurologic assessment of the limb.
D. Administering an anti-inflammatory.
Correct Answer: B. Taking a dorsoplantar radiograph.
Rationale: Radiographs (X-rays) are the gold standard for confirming a fracture. They allow
visualization of the bone, identify the fracture type, and help determine the extent of the injury. While
palpation (A) can identify signs of a fracture, it is not diagnostic and can cause further injury. A
neurologic exam (C) is important but secondary. An anti-inflammatory (D) is used for pain
management but doesn't provide a diagnosis.
8. A 5-year-old gelding is presented for a pre-purchase exam. You perform a flexion test on the
distal limb. The horse is slightly lame for 2-3 strides after the flexion test. How should you interpret
this finding in the context of a pre-purchase exam?
A. This is a normal finding and does not warrant concern.
B. This indicates a mild, likely inconsequential soft tissue injury.
C. This is a positive finding, suggesting a potential subclinical issue in the joint or soft tissues.
D. The test must be repeated in 30 minutes to confirm the result.
Correct Answer: C. This is a positive finding, suggesting a potential subclinical issue in the joint or
soft tissues.
Rationale: In a pre-purchase exam, a positive flexion test is a significant finding that warrants further
investigation. Flexion tests are designed to stress specific joints and soft tissues; a positive result often
indicates underlying pathology, such as arthritis or a tendon/ligament injury, that may not be
, apparent at rest. It is not considered normal (A), nor is it considered a minor or repeatable finding (B,
D).
9. A 2-year-old, 25 kg Beagle presents with severe, acute vomiting and diarrhea. The owner thinks
the dog may have ingested a box of raisins. What is the primary initial treatment goal for this
patient?
A. Administer intravenous fluids and antiemetics.
B. Induce vomiting with apomorphine.
C. Perform an abdominal ultrasound.
D. Administer activated charcoal.
Correct Answer: B. Induce vomiting with apomorphine.
Rationale: In a patient presenting within a few hours of a potentially toxic ingestion, the primary
initial treatment goal is to decontaminate the gastrointestinal tract. Emesis (inducing vomiting) is the
most effective way to remove the toxic substance from the stomach. Apomorphine is a standard
emetic for dogs. While IV fluids (A) and supportive care are crucial, they are secondary to
decontamination. Activated charcoal (D) is given after emesis to bind any remaining toxin.
10. A 12-year-old cat presents with progressive weight loss, polyuria, polydipsia, and a poor hair
coat. The owner reports the cat has a voracious appetite but is still losing weight. What is the most
likely diagnosis for this patient?
A. Diabetes mellitus.
B. Hyperthyroidism.
C. Chronic kidney disease.
D. Lymphoma.
Correct Answer: B. Hyperthyroidism.
Rationale: Hyperthyroidism is a common disease of older cats, characterized by a hypermetabolic
state. The classic clinical signs include weight loss, polyuria, polydipsia, a poor hair coat, and a
ravenous appetite. While diabetes mellitus (A) also causes weight loss and polyuria, it often leads to a
decreased appetite or muscle wasting, not a voracious one. Chronic kidney disease (C) causes weight
loss but typically decreases appetite. Lymphoma (D) can cause weight loss but is not associated with
polyuria or polydipsia.
11. A 3-year-old Arabian horse presents with epistaxis (nosebleed) and swelling over the right
frontal sinus. The horse has a history of a recent upper respiratory infection. What is the most
likely cause of the epistaxis?
A. Guttural pouch mycosis.
B. Sinusitis with a secondary hemorrhage.
C. Nasal laceration.
D. Ethmoid hematoma.
Correct Answer: B. Sinusitis with a secondary hemorrhage.
