A 12-year-old cat presents with weight loss despite polyphagia, vomiting, and a palpable ventral neck mass. T4 is 8.2 µg/dL. Which drug is the most common first-line medical treatment?

Accepted Answer

Methimazole

Answer

Methimazole inhibits thyroid hormone synthesis and is the primary medical management for feline hyperthyroidism before surgery or radioiodine therapy.

Question 2

A puppy presents with intussusception confirmed via ultrasound. Which predisposing condition should be ruled out after surgical correction?

Accepted Answer

Parvoviral enteritis

Answer

Canine parvovirus causes severe enteritis and hypermotility that predisposes puppies to intussusception, and its presence determines additional management.

Question 3

Which of the following findings on abdominal ultrasound is most consistent with Addison's disease (hypoadrenocorticism) in a dog?

Small, thin adrenal glands bilaterally

Answer

Primary hypoadrenocorticism causes adrenocortical atrophy, resulting in adrenal glands that appear smaller than normal (<3 mm) on ultrasound.
