Introduction
,This comprehensive practice examination is designed to prepare candidates for the American Association of
Veterinary State Boards (AAVSB) Program for the Assessment of Veterinary Education Equivalence (PAVE)
Qualifying Science Examination (QSE). The assessment evaluates foundational knowledge across the core
veterinary science domains including anatomy, physiology, pharmacology, microbiology, pathology, parasitology,
and clinical sciences. Through multiple-choice questions and real-world clinical scenarios, candidates demonstrate
the scientific knowledge and clinical reasoning required for veterinary practice. This examination serves as a
critical tool for assessing readiness for the QSE, emphasizing evidence-based medicine, diagnostic reasoning, and
professional standards in veterinary care.
SECTION ONE: QUESTIONS 1–100
1. Which of the following anatomical structures is responsible for the production of cerebrospinal fluid (CSF) in
the canine brain?
A. Arachnoid villi
B. Choroid plexus
C. Cerebral aqueduct
D. Fourth ventricle
🟢B
,🔴 RATIONALE: The choroid plexus, located in the ventricles of the brain, is responsible for the production of
cerebrospinal fluid (CSF). Arachnoid villi are involved in CSF reabsorption, not production.
2. A 5-year-old dog is presented with a history of polydipsia, polyuria, and weight loss. Fasting blood glucose is
350 mg/dL. Which of the following is the most likely diagnosis?
A. Diabetes insipidus
B. Diabetes mellitus
C. Cushing's syndrome
D. Hyperthyroidism
🟢B
🔴 RATIONALE: Polydipsia, polyuria, weight loss, and hyperglycemia are classic signs of diabetes mellitus in
dogs. Diabetes insipidus presents with polydipsia and polyuria but normal blood glucose. Cushing's syndrome
typically presents with polyphagia, and hyperthyroidism is more common in cats.
3. A 3-year-old cat is presented with a history of vomiting, lethargy, and anorexia. Blood work reveals azotemia,
hyperkalemia, and hyperphosphatemia. Which of the following is the most likely diagnosis?
A. Acute kidney injury
B. Chronic kidney disease
, C. Urinary tract infection
D. Diabetes mellitus
🟢A
🔴 RATIONALE: Acute kidney injury (AKI) presents with azotemia, hyperkalemia, and hyperphosphatemia.
Chronic kidney disease may also present with these findings but typically has a more gradual onset. Urinary
tract infections do not typically cause azotemia unless severe.
4. In a cow, which of the following organs is responsible for fermentation of ingested feed?
A. Abomasum
B. Omasum
C. Rumen
D. Reticulum
🟢C
🔴 RATIONALE: The rumen is the primary site of microbial fermentation in ruminants. The reticulum, omasum,
and abomasum also play roles in digestion, but fermentation primarily occurs in the rumen.
5. A 2-year-old horse is presented with a history of colic, fever, and diarrhea. Fecal examination reveals small,
motile, flagellated protozoa. Which of the following is the most likely causative agent?
