Which antiemetic blocks the NK1 receptor and is most effective for chemotherapy-induced vomiting in dogs?
Answer: Maropitant (Cerenia)
Maropitant is an NK1 receptor antagonist that blocks substance P at the emetic center, making it the most effective broad-spectrum veterinary antiemetic.
What is the antidote for acetaminophen toxicity in cats?
Answer: N-acetylcysteine (NAC)
NAC replenishes glutathione stores depleted by the toxic metabolite NAPQI, preventing further oxidative damage to hemoglobin and liver.
Which drug requires therapeutic drug monitoring due to its narrow therapeutic index in dogs?
Answer: Phenobarbital
Phenobarbital has a narrow therapeutic range (15-45 mcg/mL) where the effective dose is close to the toxic dose, requiring regular blood level checks.
What is the recommended protocol for IV fluids in a cat with moderate (5-7%) dehydration?
Answer: Calculate deficit and replace over 12-24 hours plus maintenance rate
The deficit is calculated (body weight x percent dehydration x 1000 = mL) and replaced gradually over 12-24 hours while providing maintenance fluids.
Which topical flea preventative distributes through skin lipids and kills parasites on contact without requiring a bite?
Answer: Fipronil-based spot-on treatments
Fipronil distributes through sebaceous glands and the skin lipid layer, killing fleas and ticks on contact as they move through treated fur.
What is a washout period in veterinary pharmacology?
Answer: Time required for a drug to be eliminated before starting a potentially interacting medication
A washout period is the time needed for substantial drug elimination before introducing a new medication that could interact dangerously, typically 5-7 half-lives.
