PHARMACOLOGY NSG 100 EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS
Pharmacokinetics
The process by which drugs are absorbed, distributed within the body, metabolized, and
excreted.
(What the body does to the drug)
Pharmacodynamics
The study of what the drug does to the body
Pharmacotherapeutics
The treatment of pathologic conditions through the use of drugs
Ways drugs can be classified
Classification indicates the effect of a medication on a body system, the symptoms
relieved, or desired effect.
(therapeutic use is the desired effect, mechanism of action is how it achieves the effect)
Meds usually have more than one classification
What are the types of drug names and what they represent
o Generic - official non proprietary name assigned by the USAN, typically shorter and
simpler than trade name
o Trade name - brand name, given my manufactory, usually catchy or memorable for
marketing
, o Chem name - exact chem composition of drug, written using nomenclature system
and rather complicated, wont see on prescription orders but could be on drug studies
Types of drug actions
o Attachment - drug forming bond on specific sites on body,
o Receptor sites - where they bond to cell membranes that change cells activity
What is it mean if a drug is an Agonist?
a drug that binds to a receptor in a cell and produces a response, similar to the action of
the substance that normally binds to the receptor
What is it mean if a drug is a partial agonist?
a drug that interacts with a receptor but produces less than the maximal effect
definition from class - attaches at site but only slight chem reaction that mimics some of
process is produced
What is it mean if a drug is an antagonist?
still attaches at site but no chem drug is produced and prevents activation of that
receptor so inhibits something in the body
What are the basic drug processes?
absorption, distribution, metabolism, excretion/elimination
What is drug absorption?
How the drug enters the body and enters circulation
Processes Include
· Solubility - ability to dissolve
