  1. Which drug is used to reverse the sedative and analgesic effects of medetomidine in dogs and cats?

    Answer: Atipamezole

    Atipamezole is a specific alpha-2 adrenergic antagonist used to reverse medetomidine and dexmedetomidine sedation in dogs and cats.

  2. Which of the following best describes the pharmacokinetic term 'volume of distribution' (Vd)?

    Answer: A theoretical volume relating plasma drug concentration to total drug in the body

    Volume of distribution is a theoretical volume that relates the total amount of drug in the body to the concentration measured in plasma.

  3. Aminoglycoside antibiotics (e.g., gentamicin) should be used with extreme caution in patients with which condition?

    Answer: Renal insufficiency

    Aminoglycosides are nephrotoxic and require renal elimination; pre-existing renal insufficiency greatly increases the risk of drug accumulation and toxicity.

  4. A ferret with insulinoma is being treated medically. Which drug is used to increase blood glucose by inhibiting insulin secretion?

    Answer: Diazoxide

    Diazoxide inhibits pancreatic insulin secretion and promotes glycogenolysis, making it useful for managing hypoglycemia in ferrets with insulinoma.

  5. Which fluoroquinolone is known to cause retinal degeneration in cats, particularly at high doses?

    Answer: Enrofloxacin

    Enrofloxacin at high doses has been associated with acute retinal degeneration and blindness in cats, and dosing must be carefully limited in this species.

  6. What is the primary mechanism by which ivermectin kills parasites?

    Answer: Potentiates glutamate-gated chloride channels causing paralysis

    Ivermectin potentiates glutamate-gated chloride channels in invertebrate nerve and muscle cells, causing hyperpolarization, paralysis, and death of the parasite.

  7. Which drug is used to treat hyperthyroidism in cats by blocking thyroid hormone synthesis?

    Answer: Methimazole

    Methimazole inhibits thyroid peroxidase, thereby blocking the synthesis of thyroid hormones and is the most common medical management for feline hyperthyroidism.
