Mixed Deck — All ICVA Topics Flashcards

A horse with equine protozoal myeloencephalitis (EPM) most commonly shows which clinical sign?

Answer: Asymmetric ataxia and muscle atrophy

EPM typically causes asymmetric ataxia, weakness, and focal muscle atrophy due to multifocal CNS lesions.

What is the primary action of the deep digital flexor tendon (DDFT) in the equine foot?

Answer: Flexion of the coffin joint and support of the navicular bone

The DDFT flexes the coffin joint and wraps around the navicular bone, placing it under significant tension during weight-bearing.

Which vaccine type is most effective for preventing Clostridium perfringens type D (pulpy kidney disease) in sheep?

Answer: Toxoid (inactivated toxin) vaccine

Clostridial toxoid vaccines containing inactivated epsilon toxin provide effective protection against Clostridium perfringens type D and are standard practice in sheep management.

A 10-year-old neutered male dog presents with weight loss, ravenous appetite, and diarrhea. A cranial abdominal mass is palpated. Ultrasound shows a hypoechoic pancreatic mass. The most likely diagnosis is:

Answer: Insulinoma

Insulinoma is the most common functional pancreatic tumor in dogs, causing hypoglycemia-driven polyphagia, weakness, and seizures.

Under global veterinary standards, which principle requires that antimicrobials critically important for human medicine be restricted in veterinary use?

Answer: Antimicrobial stewardship

Antimicrobial stewardship principles restrict or require careful oversight of critically important antimicrobials in veterinary use to preserve their efficacy for human medicine.

Which of the following is considered an ethical obligation in veterinary continuing education?

Answer: Ensuring CE activities are free from significant commercial bias and represent current evidence

Ethical CE participation requires critical evaluation of commercial influences and commitment to evidence-based, unbiased content.

Which global standard framework specifically addresses the equivalence of veterinary drug residue control programs between trading countries?

Answer: Codex Alimentarius maximum residue limits (MRLs)

Codex Alimentarius MRLs for veterinary drugs provide the international benchmark against which national residue monitoring programs are evaluated for trade equivalence.

A candidate fails the NAVLE. What is the minimum waiting period before they may retake the exam?

Answer: 90 days

Candidates must wait a minimum of 90 days before retaking the NAVLE after a failed attempt.

Which radiographic finding is most consistent with a left-sided congestive heart failure in a dog?

Answer: Pulmonary venous distension and perihilar interstitial to alveolar pattern

Left-sided CHF causes pulmonary venous hypertension leading to pulmonary edema, seen radiographically as distended pulmonary veins and a perihilar interstitial to alveolar pattern.

Which analgesic is contraindicated in cats due to glucuronidation deficiency leading to hepatotoxicity?

Answer: Acetaminophen

Cats lack adequate UGT1A6 glucuronyl transferase activity, making acetaminophen highly toxic due to accumulation of reactive metabolites causing methemoglobinemia and hepatic necrosis.

Which format of CE is most appropriate when a veterinarian needs to learn a new surgical technique?

Answer: Attending a hands-on wet lab with live animal models

Psychomotor skills like surgical techniques require hands-on practice under supervision, making wet labs the most appropriate CE format.

A dog with protein-losing nephropathy (PLN) has a urine protein:creatinine ratio of 6.2. Which breed is most predisposed to glomerulonephritis due to a primary genetic defect in collagen IV?

Answer: Samoyed

Samoyeds have an X-linked hereditary nephritis caused by a mutation in the COL4A5 gene encoding type IV collagen.

A veterinary technician holds a VTS (Veterinary Technician Specialist) credential. To maintain this credential, they must typically:

Answer: Complete continuing education and re-certification requirements set by the specialty academy

VTS credentials require ongoing CE and periodic recertification through the awarding specialty academy to remain valid.

A goat herd experiences sudden deaths in does within 24 hours of parturition. Necropsy reveals hemorrhagic abomasitis. Which clostridial disease is most likely?

Answer: Clostridium perfringens type C

Clostridium perfringens type C produces beta toxin causing hemorrhagic enteritis and sudden death, particularly in neonates and periparturient does.

A 7-year-old, male neutered Miniature Schnauzer is presented with a 3-day history of vomiting, anorexia, and lethargy. On physical examination, he displays cranial abdominal pain. Laboratory results show neutrophilia, elevated amylase, and lipase. Which of the following is the most likely diagnosis?

Answer: Acute pancreatitis

The signalment (Miniature Schnauzer), clinical signs (vomiting, anorexia, cranial abdominal pain), and laboratory findings (neutrophilia, elevated amylase and lipase) are all highly suggestive of acute pancreatitis. While other conditions can cause similar signs, the combination of findings makes pancreatitis the most probable diagnosis.

Which household plant toxin found in lilies (Lilium spp.) causes acute kidney injury in cats?

Answer: Unknown nephrotoxic principle

True lilies (Lilium and Hemerocallis species) contain an unidentified nephrotoxin that causes severe acute tubular necrosis in cats, with even small exposures being potentially fatal.

A veterinary technician wants to advance to a specialty credential. What is the first step they should typically take?

Answer: Review the eligibility requirements of the relevant veterinary technician specialty academy

Each veterinary technician specialty academy has specific eligibility criteria, case logs, and examination requirements that must be reviewed first.

What is the most reliable imaging modality for evaluating the navicular bone and surrounding soft tissues in equine foot lameness?

Answer: MRI

MRI provides superior soft tissue and bone detail of the foot, including the navicular bone, impar ligament, and deep digital flexor tendon.

In computed tomography (CT), Hounsfield units (HU) are used to measure:

Answer: Electron density relative to water

Hounsfield units quantify the electron density of tissues relative to water (0 HU), with air at -1000 HU and bone at +1000 HU or higher.

A state veterinary board requests NAVLE score transcripts for a licensure application. Who is authorized to release this information?

Answer: ICVA directly to the board upon candidate authorization

ICVA releases official score transcripts directly to licensing boards upon written authorization from the candidate.
