1. Which measure best describes the probability that a person with a positive screening test truly has the disease? → Positive predictive value
2. The IACUC (Institutional Animal Care and Use Committee) is required by US regulations to include which member category? → At least one non-affiliated community member unrelated to the institution
3. What is the primary advantage of using a laryngeal mask airway (LMA) over endotracheal intubation in appropriate cases? → Requires less anesthetic depth to place
4. A horse with equine metabolic syndrome (EMS) typically shows which metabolic abnormality as the primary feature? → Peripheral insulin dysregulation (hyperinsulinemia and insulin resistance)
5. During a difficult airway, which nerve block would anesthetize the supraglottic structures above the vocal cords? → Superior laryngeal nerve internal branch block
6. Which organism is the most common cause of contagious equine metritis (CEM)? → Taylorella equigenitalis
7. In the context of pharmacodynamics, how does a non-competitive antagonist affect the agonist dose-response curve? → Reduces the maximal response (Emax) without changing the EC50.
8. A 55-year-old woman is found to have pellagra. Which vitamin deficiency is responsible for this condition? → Niacin (B3)
9. Which class of drugs causes hyperkalemia by blocking aldosterone's action in the collecting duct? → Potassium-sparing diuretics (spironolactone)
10. Body condition scoring (BCS) in dogs uses which scale and what score indicates ideal body condition? → 1–9 scale; a score of 4–5 indicates ideal condition
11. Which cell type is the primary antigen-presenting cell responsible for activating naïve T lymphocytes? → Dendritic cells
12. Which metabolic pathway is primarily responsible for synthesizing glucose from amino acids during prolonged fasting? → Gluconeogenesis
13. In the avian respiratory system, which structures allow unidirectional airflow through the lungs? → Air sacs and parabronchi
14. In dogs, which muscle of the hindlimb acts as the primary extensor of the stifle joint and is commonly assessed for atrophy in orthopedic disease? → Quadriceps femoris
15. A horse undergoing general anesthesia in dorsal recumbency is at risk for which muscle condition that can result in postoperative myopathy? → Rhabdomyolysis due to prolonged pressure on muscle groups
16. The thoracic duct drains into the venous system at which location? → Left subclavian–jugular junction
17. Which of the following best describes the appropriate use of electrocautery in the monopolar mode? → Current passes from the active electrode through the patient to a grounding pad
18. In small ruminants, what is the term for the dark, tarry, foul-smelling vaginal discharge that can indicate uterine infection postpartum? → Pyometra
19. A patient with a full stomach requires emergent general anesthesia. Which induction technique minimizes aspiration risk? → Rapid sequence induction with cricoid pressure
20. Opioid-induced hyperalgesia is BEST managed by which strategy? → Opioid rotation and multimodal analgesia with NMDA antagonists
21. Hypophosphatemia in postparturient dairy cows is most commonly associated with which condition? → Downer cow syndrome following hypocalcemia (milk fever)
22. In horses, what structure must be manually ruptured or allowed to resolve before Caslick's vulvoplasty repair can be effective for pneumovagina? → Hymen remnant
23. A cow presents with a soft, fluid-filled uterus and bilateral enlarged uterine horns at 4 weeks post-calving. The most likely diagnosis is: → Pyometra
24. On a plain abdominal radiograph, which pattern of bowel gas distribution is most consistent with small bowel obstruction? → Multiple dilated loops of small bowel centrally with a paucity of colonic gas
25. Which of the following best describes the mechanism of action for local anesthetics such as lidocaine and bupivacaine? → They block voltage-gated sodium channels, preventing nerve impulse propagation.
26. Dermatophilosis in cattle and horses is caused by Dermatophilus congolensis. What is the correct classification of this organism? → Filamentous Gram-positive actinomycete
27. Which of the following sets of clinical pathology findings is most consistent with a diagnosis of disseminated intravascular coagulation (DIC)? → Thrombocytopenia, prolonged PT, prolonged aPTT, elevated FDPs
28. On thoracic radiographs, an alveolar pattern with an air bronchogram and cranioventral distribution in a febrile dog with cough is most consistent with: → Aspiration or bacterial bronchopneumonia
29. Which kidney stone kind is most prevalent among the following? → Calcium oxalate
30. Which enzyme deficiency leads to phenylketonuria (PKU), resulting in accumulation of phenylalanine? → Phenylalanine hydroxylase
