✍️ Sample NAVLE Questions & Answers

1. Intra-articular injection of which substance is used as a visco-supplementation therapy to improve synovial fluid quality in horses with joint disease?
Hyaluronic acid (sodium hyaluronate)

Sodium hyaluronate (hyaluronic acid) is injected intra-articularly to restore viscosity and lubrication of synovial fluid, acting as visco-supplementation in arthritic joints.

2. Which of the following best describes the mechanism by which FeLV causes non-regenerative anemia in some infected cats?
Direct viral infection of erythroid precursors in bone marrow causing myelosuppression

FeLV directly infects erythroid progenitor cells in the bone marrow, impairing red blood cell production and causing non-regenerative anemia.

3. A 9-year-old cat presents with hypercalcemia (total Ca 14.2 mg/dL), weight loss, and peripheral lymphadenopathy. Which condition is most likely?
Lymphoma

Lymphoma is the most common cause of hypercalcemia of malignancy in cats, mediated by PTHrP secretion.

4. When designing a biosecurity protocol for a cow-calf operation, which practice is MOST important for preventing introduction of Bovine Leukemia Virus (BLV)?
Testing all purchased cattle for BLV antibodies before introduction and segregating positives

BLV is most effectively prevented by serological testing (AGID or ELISA) of all purchased cattle and excluding seropositive animals, since there is no approved vaccine in the US.

5. Which antifungal drug is currently the first-line treatment for aspergillosis in birds?
Voriconazole

Voriconazole is the preferred antifungal for avian aspergillosis due to its superior efficacy and safety compared to older azoles.

6. A cat presents with pleural effusion. On thoracic radiographs, which finding best differentiates pleural effusion from pulmonary consolidation?
Retraction of lung lobes from the thoracic wall

Pleural effusion causes lung lobes to retract away from the thoracic wall, whereas consolidated lung lobes remain in contact with the chest wall.
