Define veterinarian client patient relationship - ANS ✔ - the relationship that must exist between the
veterinarians, his or her patient and the patient's owner before prescription drugs may be dispensed
List four sources of drugs used in veterinary medicine - ANS ✔ - animal products, plant products,
minerals, and synthetic products
Define agonist - ANS ✔ - A drug with a high level of affinity and efficacy that binds to a receptor and
causes a specific action.
Define contraindication - ANS ✔ - a reason not to use a drug in a particular situation, causes
undesirable side effects
Define efficacy - ANS ✔ - the degree to which a drug produces its desired response.
Define over the counter drug - ANS ✔ - a drug that may be purchased without a prescription from a
vet
Define prescription drug - ANS ✔ - a drug that must be prescribed by a vet and taken while under the
supervision of a vet
Define receptor - ANS ✔ - a molecule located on a cell that binds with drugs or neurotransmitters to
cause an effect
Define therapeutic index - ANS ✔ - the relationship between a drug's ability to achieve the desired
effect compared to its tendency to produce toxic effects. Expressed as a ration between the LD and
the ED. LD/ED 50% of the time.
, Define withdrawal time - ANS ✔ - the amount of time that must elapse between the end of drug
therapy and the elimination of that drug from the patient’s tissue or products.
What are four components of a drug regimen - ANS ✔ - includes the dose, the route of administration,
the frequency of administration, and the duration of administration
Discuss the conditions that must be met before a valid veterinarian-client-patient relationship can be
shown to exist. - ANS ✔ - 1. The vet must assume responsibility for making clinical judgements in
relation to the health of the animal. 2. The vet must have recently seen the animal and be acquainted
with its care and 3. The vet must be available for follow up care of the animal.

and monitor patient in a responsible way.
Describe the sequence of events that a drug undergoes from administration to excretion. - ANS ✔ - a
drug is first absorbed or directly placed into the bloodstream. In the blood, the drug may bind with a
plasma protein or exist in the Free State. The circulating blood distributes the drug to the capillary
level, where the drug leaves the circulation and enters the interstitial fluid. The interstitial fluid
bathes the cell or bind with surface receptors. The drug then exits the cell or its surface, moves back
to interstitial fluid, reenters circulation and then is metabolized in the liver and sent to the kidneys
for excretion.
List 11 possible routes for administering a drug and discuss the advantages and/or disadvantages of
each. - ANS ✔ - 1. Oral route 2. SQ 3.IM 4. IV 5. IP 6. IA, intraarterial 7. IC, intracardiac 8. IM,
intramedullary 9. Inhalation 10. Topical 11. Intradermal
List some of the factors that influence drug absorption - ANS ✔ - 1. Method of absorbtion, 2. The ph
of the durg and its ionization status, 3. The absorptive surface area, 4. The blood supply to the area,
5. The solubility of the drug, 6. The dosage form, 7. The status of the gi tract 8 interactions with other
drugs
Most biotransformation of drugs occurs in where? - ANS ✔ - liver
Must durg excretion occurs via? - ANS ✔ - kidneys
