Describe how drugs affect the nervous system
→ Drugs affect the nervous system by acting at the synaptic junctions to promote
neurotransmitter's activity, mimic their actions, or block them from acting.
Identify examples of respiratory drugs
→ Expectorants, mucolytics, antitussives, bronchodilators, decongestants
List which drugs are used to relieve pain and inflammation
→ NSAIDs, Opioids, Antihistamines, muscle relaxers, steroids, nerve blocks
Describe how antiparasitic drugs work
→ Antiparasitic drugs work by destroying parasites or inhibiting their growth. Most work
by interfering with the parasite's nervous system to prevent them from moving.
Discuss why replacement drugs are often necessary for animal health
→
Explain the veterinary technician's role in inventory control
→ keeping the staff informed regarding discontinued items, knowing the dates on which
backordered items will be released from the vendor, packing up goods awaiting
return to the vendor (e.g., expired items), rotating stock correctly, maintaining current
prices on all products, organizing inventory for ease of location and counting, receiving
and inspecting orders on arrival at the veterinary facility, and learning about new
products.

Define: Veterinarian-client-patient relationship

prescription drugs can be dispensed.
List 4 sources of drugs used in Vet Med
→ Animal product, plant material, minerals, synthetic products
What are 4 components of a drug regimen?
→ Dose, route, frequency, and duration of administration.
Discuss the conditions that must be met before a valid veterinarian-client-patient relationship
can be shown to exist
→ 1.vet must assume responsibility for making clinical judgments in relation to health of
the animal.
→ 2. Vet must have recently seen the animal and be acquainted with it's care.
→ 3.Vet must be available for follow-up care of the animal
Discuss the responsibilities of a vet tech in the administration of drug orders
→ To carry out the vet's orders correctly. should read the drug label three times to ensure
proper drug is being administered and should take care to administer correct dose by
correct route. Should be aware of the expected affects and potential adverse side
effects and be able to monitor the patient.
Describe the sequence of events that a drug undergoes from administration to excretion
→ Drug is absorbed (or placed directly) into the bloodstream, the drug may bind with
plasma in the blood or may exist in free state, circulating blood distributes drug to
capillary level where it leaves circulation and enters interstitial fluid. it bathes the cell
and allows drug to bind to cell surface receptors or enter the cell. It then exits the cell
and moves back into interstitial fluid, reenters circulation, and is transported to liver for
metabolism. The metabolite is then transported to kidneys for excretion.

List some of the factors that influence drug absorption
→ Method of absorption, pH of the drug and ionization status, absorptive surface area,
blood supply to area, solubility of drug, dosage form, status of GI tract, and
interactions with other drugs
Most biotransformation occurs in the_____
→ Liver
Most drug excretion occurs via the ______
→ Kidneys
Drugs usually produce their effects by combining with specific cellular_____
→ Receptors

called
