SECTION 1: COMPANION ANIMAL (DOGS AND CATS) Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 6-year-old Golden Retriever presents with progressive difficulty rising, reluctance to
climb stairs, and shifting forelimb lameness that worsens after rest. Physical
examination reveals pain on extension of both elbows and mild atrophy of the
quadriceps muscles. Radiographs show osteophytosis and subchondral sclerosis of the
elbow joints. Which treatment modality is most appropriate for long-term management?
A. Daily oral carprofen and controlled exercise with weight management ✓ CORRECT
B. High-dose prednisone and complete cage rest for 4 weeks
C. Immediate bilateral elbow arthrodesis to eliminate joint motion
D. Weekly intra-articular corticosteroid injections indefinitely
Correct Answer: A
Rationale: Degenerative joint disease in large-breed dogs responds best to NSAIDs,
weight control, and moderate activity to maintain muscle mass without exacerbating
,cartilage damage. High-dose prednisone offers inferior analgesia compared to NSAIDs
and predisposes to muscle atrophy and iatrogenic hyperadrenocorticism. Long-term
multimodal therapy improves quality of life more than surgical fusion in most cases.
Question 2 of 50
A 3-year-old indoor-only domestic shorthair cat presents with acute vomiting, lethargy,
and anorexia of 24 hours duration. The owner reports the cat chewed on a bouquet of
lilies brought home yesterday. On presentation, the cat is dehydrated with bilateral
renomegaly and a serum creatinine of 6.8 mg/dL. Which immediate intervention is most
critical?
A. Administer methocarbamol to control tremors from neurotoxicity
B. Initiate aggressive intravenous fluid diuresis and evaluate urine output ✓ CORRECT
C. Perform emergency peritoneal dialysis before obtaining a urinalysis
D. Administer activated charcoal orally to bind remaining toxin in the colon
Correct Answer: B
Rationale: Lily nephrotoxicity causes acute tubular necrosis, and aggressive IV fluid
therapy is the cornerstone of treatment to maintain renal perfusion and promote
diuresis. Activated charcoal is ineffective for lily toxicosis because the toxin is rapidly
absorbed and causes vomiting that precludes oral administration. Peritoneal dialysis is
reserved for anuric renal failure unresponsive to medical management.
Question 3 of 50
A 9-year-old male neutered Dachshund presents with acute onset of non-ambulatory
paraparesis, absent deep pain sensation in the pelvic limbs, and a firm, painful
thoracolumbar spine on palpation. The owner reports the dog jumped off the sofa six
hours ago. MRI reveals an extruded disk at T12-T13 with spinal cord compression.
Which surgical approach offers the best chance of functional recovery?
,A. Dorsal laminectomy without removal of the herniated nucleus pulposus
B. Hemilaminectomy at the contralateral side to preserve facet joints
C. Hemilaminectomy with gentle removal of compressive disk material ✓ CORRECT
D. Intervertebral disk fenestration alone without addressing the extrusion
Correct Answer: C
Rationale: Hemilaminectomy provides direct access to lateralized disk extrusions in the
thoracolumbar region, allowing immediate spinal cord decompression. Fenestration
alone does not relieve existing compression and is typically performed prophylactically
at adjacent sites. Preservation of deep pain sensation is the strongest prognostic
indicator, but even dogs without deep pain can recover with rapid decompression.
Question 4 of 50
A 5-year-old intact male German Shepherd Dog presents with a two-week history of
progressive exercise intolerance, cough, and syncope during excitement. Auscultation
reveals a split S2 sound and a systolic murmur loudest over the left heart base.
Echocardiography shows severe right ventricular hypertrophy and a dilated main
pulmonary artery. Which condition is most consistent with these findings?
A. Dilated cardiomyopathy with secondary mitral regurgitation
B. Patent ductus arteriosus with left-to-right shunting
C. Subaortic stenosis causing pressure overload of the left ventricle
D. Heartworm disease causing pulmonary hypertension and cor pulmonale ✓ CORRECT
Correct Answer: D
Rationale: Chronic heartworm infection leads to pulmonary vascular remodeling,
pulmonary hypertension, and right ventricular hypertrophy with a characteristic split S2
from delayed pulmonic valve closure. Dilated cardiomyopathy primarily affects the left
ventricle and would not produce right-sided heart base changes. German Shepherds are
not a breed typically predisposed to subaortic stenosis.
Question 5 of 50
, A 4-year-old Labrador Retriever presents with acute onset of head tilt, horizontal
nystagmus with the fast phase toward the left, and circling to the left. The dog has
vomited twice and shows no evidence of paresis or proprioceptive deficits in the limbs.
Neurologic examination localizes the lesion to the left vestibular apparatus. Which is the
most likely diagnosis?
A. Peripheral vestibular disease from otitis media-interna ✓ CORRECT
B. Cerebellar infarction causing central vestibular signs
C. Meningioma compressing the right vestibular nuclei
D. Intervertebral disk disease at C1-C2 affecting proprioception
Correct Answer: A
Rationale: Head tilt and nystagmus toward the side of the lesion with intact postural
reactions indicate peripheral vestibular disease, and otitis media-interna is the most
common cause in dogs. Central vestibular disease typically produces vertical or rotary
nystagmus and ipsilateral proprioceptive deficits. Cerebellar lesions cause intention
tremor and dysmetria rather than true vestibular signs.
Question 6 of 50
A 2-year-old spayed female domestic shorthair cat presents with episodic coughing,
wheezing, and open-mouth breathing that occurs during spring and summer. Thoracic
radiographs reveal a bronchial pattern with evidence of air trapping. Tracheal wash
cytology shows increased eosinophils. Which long-term management strategy is most
appropriate?
A. Chronic low-dose prednisolone at immunosuppressive doses daily
B. Inhaled corticosteroids via a spacer and bronchodilators as needed ✓ CORRECT
C. Prophylactic amoxicillin-clavulanate administered monthly
D. Surgical removal of the right middle lung lobe to eliminate the trigger
Correct Answer: B
