NURS 2535 Midterm Exam Questions With
Complete Answers
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.
Factors such as blood flow, tissue permeability, and the drug's chemical properties
influence its distribution to different parts of the body.
pharmacokinetics elimination - ANSWER elimination: Elimination refers to the removal of
the drug and its metabolites (breakdown products) from the body.
The primary route of elimination is through the kidneys via urine, but drugs can also be
eliminated through other routes such as the livrefers to the removal of the drug and its
metabolites (breakdown products) from the body.
The primary route of elimination is through the kidneys via urine, but drugs can also be
eliminated through other routes such as the liver (via bile), lungs (via exhalation), and
sweat.
The rate of elimination determines how long the drug remains in the body and affects its
overall duration of action.er (via bile), lungs (via exhalation), and sweat.
The rate of elimination determines how long the drug remains in the body and affects its
