Question 1

A 7-year-old spayed female cat presents with polyuria, polydipsia, and a palpable ventral neck mass. T4 is markedly elevated. Which treatment option is considered curative?

Accepted Answer

Radioactive iodine (I-131) therapy

Answer

Radioactive iodine (I-131) is the treatment of choice for feline hyperthyroidism as it selectively destroys hyperfunctional thyroid tissue and is considered curative with a single dose.

Question 2

A 2-year-old intact male dog presents with acute scrotal swelling, fever, and pain. Orchitis is suspected. What is the most appropriate initial management?

Accepted Answer

Castration and broad-spectrum antibiotics

Answer

Castration combined with broad-spectrum antibiotics is recommended for bacterial orchitis to eliminate the infection source, prevent abscess formation, and avoid systemic sepsis.

Question 3

A horse presents with acute colic, nasogastric reflux >2 L, absent borborygmi on the right side, and tachycardia of 68 bpm. What is the most likely diagnosis?

Accepted Answer

Duodenitis-proximal jejunitis

Answer

Large volumes of nasogastric reflux (>2 L) combined with absent right-sided borborygmi, severe tachycardia, and acute pain are classic for duodenitis-proximal jejunitis (anterior enteritis).

Question 4

A rabbit presents with acute respiratory distress, cyanosis, and sudden death of several cage-mates over 24 hours. Necropsy reveals multifocal hepatic necrosis and pulmonary hemorrhage. The most likely etiologic agent is:

Accepted Answer

Rabbit hemorrhagic disease virus (RHDV)

Answer

Rabbit hemorrhagic disease virus causes peracute mortality with hepatic necrosis, disseminated intravascular coagulation, and pulmonary hemorrhage, often affecting multiple animals rapidly.

Question 5

A 10-year-old dog is diagnosed with stage 3 chronic kidney disease (IRIS). Which dietary modification is most appropriate?

Accepted Answer

Phosphorus restriction with moderate protein reduction

Answer

Phosphorus restriction slows CKD progression by reducing renal secondary hyperparathyroidism, and moderate protein reduction decreases uremic toxin accumulation without worsening malnutrition.
