  1. What is the primary concern when administering xylazine to cattle compared to other species?

    Answer: Cattle are 10 times more sensitive to xylazine than horses

    Cattle are approximately 10 times more sensitive to xylazine than horses, so doses must be drastically reduced to avoid profound sedation and cardiorespiratory depression.

  2. A technician is preparing doxycycline for a patient. Which administration guideline is critical to prevent esophageal stricture in cats?

    Answer: Follow each dose with water or food to clear the esophagus

    Doxycycline tablets can cause esophageal stricture in cats if they lodge in the esophagus, so each dose must be followed by water or food to ensure the pill reaches the stomach.

  3. Which drug is used to treat toxoplasmosis in cats?

    Answer: Clindamycin

    Clindamycin is the drug of choice for treating toxoplasmosis in cats due to its efficacy against Toxoplasma gondii.

  4. Atropine is classified as which type of drug?

    Answer: Anticholinergic (muscarinic antagonist)

    Atropine is an anticholinergic drug that competitively blocks muscarinic acetylcholine receptors, increasing heart rate and decreasing secretions.

  5. Which medication is used to stimulate appetite in cats and works by acting as a serotonin antagonist?

    Answer: Cyproheptadine

    Cyproheptadine is a serotonin and histamine antagonist that stimulates appetite in cats, though mirtazapine is also used; cyproheptadine specifically is the classic serotonin antagonist appetite stimulant.

  6. A dog receives an accidental overdose of acepromazine. What is the most appropriate treatment?

    Answer: Provide supportive care including IV fluids and vasopressors

    There is no specific reversal agent for acepromazine; treatment is supportive, including IV fluids and vasopressors (such as phenylephrine) for hypotension.

  7. Which antiparasitic drug works by disrupting the nervous system of invertebrates by potentiating glutamate-gated chloride channels?

    Answer: Ivermectin

    Ivermectin (a macrocyclic lactone) potentiates glutamate-gated chloride channels in invertebrates, causing hyperpolarization and paralysis of parasites.
