1. A 22-kg dog is prescribed amoxicillin at a dosage of 20 mg/kg PO
every 12 hours. The clinic stocks 250-mg tablets. Which dose is
closest to the calculated amount per administration?
A. 220 mg
B. 330 mg
C. 440 mg
D. 550 mg
Answer: C. 440 mg
Rationale: The calculation is 22 kg × 20 mg/kg = 440 mg per dose. The
important pharmacology principle is that the prescribed dose should
first be calculated from body weight and then converted into a
practical formulation. A 250-mg tablet does not permit an exact 440-
mg dose, so the veterinarian must select an appropriate tablet
combination, alternative concentration, or formulation rather than
arbitrarily rounding the dose.
2. Which pharmacokinetic process describes movement of a drug
from the site of administration into the systemic circulation?
1
,A. Distribution
B. Absorption
C. Metabolism
D. Elimination
Answer: B. Absorption
Rationale: Absorption is the movement of a drug from its
administration site into systemic circulation. Distribution describes
movement from blood into tissues, metabolism involves chemical
alteration of the drug—often hepatic—and elimination refers
primarily to removal through renal, biliary, pulmonary, or other
routes.
3. A drug has a very high volume of distribution in a canine patient.
What does this most strongly suggest?
A. The drug remains almost entirely within plasma
B. The drug is extensively distributed into tissues
C. The drug cannot cross cell membranes
D. The drug must be eliminated exclusively through the kidneys
Answer: B. The drug is extensively distributed into tissues
Rationale: A high apparent volume of distribution generally indicates
extensive movement of the drug from plasma into tissues or other body
compartments. It does not necessarily represent a literal anatomical
volume. Drugs that are highly tissue-bound or lipophilic may have
very large apparent volumes of distribution.
4. Which route of administration generally provides 100% systemic
bioavailability when the drug is completely delivered into the
systemic circulation?
2
,A. Oral
B. Subcutaneous
C. Intravenous
D. Intramuscular
Answer: C. Intravenous
Rationale: Intravenous administration places the drug directly into
systemic circulation, so bioavailability is considered 100%. Oral drugs
may undergo incomplete absorption and first-pass metabolism. IM and
SC administration can also have less than complete bioavailability
depending on formulation, perfusion, and drug characteristics.
5. A cat receives a drug that is extensively metabolized by hepatic
glucuronidation. Why may cats be particularly susceptible to
toxicity from some drugs undergoing this pathway?
A. Cats have excessive renal filtration
B. Cats have limited capacity for certain glucuronidation reactions
C. Cats cannot metabolize any lipid-soluble drugs
D. Cats have no hepatic metabolic enzymes
Answer: B. Cats have limited capacity for certain glucuronidation
reactions
Rationale: Cats have species-specific limitations in certain hepatic
glucuronidation pathways. Consequently, some compounds that are
readily conjugated and eliminated in other species may persist longer
or produce toxicity in cats. This is a classic reason veterinary
pharmacology cannot simply extrapolate canine dosing to feline
patients.

, 6. Which pharmacokinetic parameter is most directly associated
with the time required for plasma drug concentration to decrease by
approximately 50% during the terminal elimination phase?
A. Bioavailability
B. Half-life
C. Volume of distribution
D. Clearance
Answer: B. Half-life
Rationale: Drug half-life is the time required for plasma concentration
to fall by approximately half during the relevant elimination phase.
Half-life is influenced by clearance and volume of distribution and is
important when determining dosing intervals and estimating the time
required for drug concentrations to decline.
7. A drug follows first-order elimination kinetics. Which statement
is most accurate?
A. A constant amount of drug is eliminated per unit time
B. A constant percentage or fraction of drug is eliminated per unit time
C. Elimination occurs only when plasma concentrations are zero
D. Elimination is completely independent of concentration
Answer: B. A constant percentage or fraction of drug is eliminated
per unit time
Rationale: In first-order kinetics, the rate of elimination is
proportional to drug concentration, so a relatively constant fraction is
eliminated per unit time. In zero-order kinetics, a relatively constant
amount is eliminated per unit time because the relevant elimination
pathway is saturated.
