NURS 2535 MIDTERM QUESTIONS AND ANSWERS
SCORED A+.
pharmacology definition Answer - the study of the origin, chemistry, and the
uses of drugs and their effects on the body
Drug definition Answer - Chemical substance that influence living things and
have therapeutic action and application
Pharmacotherapeutics Answer - use of drugs to diagnose, prevent, treat
disease or prevent pregnancy
what is a drug Answer - substance capable of altering biochemical and
physiological processes in the body
- can have desirable or undesirable responses
-DO NOT CHANGE AND OR CREATE NEW FXNS
only modify existing fxns or speed/slow up existing ones
properties of an ideal drug
- effectiveness Answer - Elicits the response of why it is ordered
properties of an ideal drug
,- selectivity Answer - elicits only the response for which it is given, ideally
should not cause side effects
properties of an ideal drug
- reversibility Answer - effect of drug should be reversible
properties of an ideal drug
- predictability Answer - need to know how a patient will respond
properties of an ideal drug
- Ease of Administration Answer - Simple to administer, convenient route
properties of an ideal drug
- Minimal Drug Interactions Answer - Multi-drug Therapy.
In "Multi-drug Therapy," it means that the drug can be safely used alongside
other medications without causing harmful interactions.
properties of an ideal drug
- chemical stability Answer - Stay effective during storage and mixing
properties of an ideal drug
- possessing a simple name Answer - Chemical name, Generic name and Trade
name
N-acetyl-para-aminophenol - Acetaminophen (Tylenol)
what factors influence drug responses? Answer - Administration: Drug form,
route, multiple drug therapy, drug interactions
, Pharmacokinetics: What the body does to the drug: Absorption, distribution,
metabolism, excretion
Pharmacodynamics: How the drug effects the body: Onset, peak & duration,
therapeutic range, s/e, adverse reaction
Clinical Factors: Age, weight, present health disorder, other disease entities,
client drug compliance.
Drug therapy should provide maximal benefit with minimal harm
Pharamkokinetics Answer - Drug adminstered --> Drug absorption --> drug
distribution --> drug elimination and drug metabolism
then transfer to site of action (pharmacodynamics)
pharmacodynamics Answer - regulatory proteins --> binds to molecular target
--> (affinity) --> mechanism of drug action --> response to drug --> efficacy (or
toxicity)
pharmacokinetics absorption Answer - absorption: Absorption refers to the
process by which a drug enters the bloodstream from its site of administration
(e.g., oral, intravenous, topical).
For example, if you take a pill orally, the drug must first be absorbed from the
digestive tract into the bloodstream before it can reach its target tissues or
organs.
pharmacokinetics distribution Answer - distribution: Distribution involves how
the drug is transported throughout the body after it has been absorbed into
the bloodstream.
Once in the bloodstream, the drug is circulated to various tissues and organs,
where it may exert its effects.
