Penn Foster Vet Tech Pharmacology questions with
correct answers
define agonist Correct Answer-A drug with a high level of affinity and
efficacy that binds to a receptor and casues a specific action.
define contraindiction Correct Answer-a reason not to use a drug in a
particular situation, causes undesirable side effects
define efficacy Correct Answer-the degree to which a drug produces its
desired response.
define over the counter drug Correct Answer-a drug that may be
purchased without a prescription from a vet
define prescription drug Correct Answer-a drug that must be prescribed
by a vet and taken while under the supervision of a vet
define receptor Correct Answer-a molecule located on a cell that binds
with drugs or neurotransmitters to cause an effect
define therapeutic index Correct Answer-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 Correct Answer-the amount of time that must
elapse between the end of drug therapy and the elimination of that drug
from the patients tissue or products.
define veterinarian client patient relationship Correct Answer-the
relationship that must exist between the veterinarians, hris or her patient
and the patient's owner before prescription drugs may be dispensed
List four sources of drugs used in veterinary medicine Correct Answer-
animal products, plant products, minerals, and synthetic products
what are four components of a drug regimen Correct Answer-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. Correct Answer-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.
discuss the responsibilities of a veterinary technician in the
administration of drug orders. Correct Answer-carry out orders
correctly, read the drug label 3x to ensure that the proper drug is being
adminstered and take care to administer the correct dose by the correct
route. be aware of posibble side effects and monitor patient in a
responsible way.
, Describe the sequense of events that a drug undergoes from
administration to excretion. Correct Answer-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
advatages and/or disadvantages of each. Correct Answer-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 Correct Answer-
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? Correct Answer-liver
Must durg excretion occurs via? Correct Answer-kidneys
Drugs usually produce their effects by combining with specific cellular
Correct Answer-receptors
