Introduction to Pharmacology for NURE 130
Exam Questions With 100% Verified
Answers
Pharmacology - answer✔The science of drugs, their composition, uses, and effects.
Nurses need to have knowledge about the actions and effects of medications.
To safely and accurately administer medications nurses need to have an understanding of
pharmacologic principles.
chemical name - answer✔Describes the drug's chemical composition and molecular structure
Generic name (nonproprietary name) - answer✔Name given by the United States Adopted
Names Council
Trade name (proprietary name) - answer✔The drug has a registered trademark; use of the name
is restricted by the drug's patent owner (usually the manufacturer)
pharmacological concepts: classification - answer✔Classification- Nurses learn to categorize
meds with similar characteristics by their class
Medication classification indicates the effect of the med on the body system, the symptom the
med relieves, or the med's desired effect (e.g. oral hypoglycemic, beta blockers)
A medication may also be part of more than one class
Aspirin is an analgesic, antipyretic, anti-inflammatory, and anti-platelet agent
forms of medications - answer✔Medications are available in a variety of forms and preparations
The form of the med will determine its route of administration
Composition of med is designed to enhance its absorption & metabolism
Many meds are available in several forms
Pharmacokinetics - answer✔The processes of drug absorption, drug distribution, drug
metabolism and drug excretion
Absorption
Distribution
Metabolism
Excretion
It's important to understand the difference between pharmacokinetics (drug movement) and
pharmacodynamics (drug action)
pharmaceutical phase (I) - answer✔disintegration of dosage form; dissolution of drug in body
pharmacokinetic phase (II) - answer✔absorption, distribution, metabolism, excretion
Pharmacodynamic Phase (III) - answer✔drug-receptor interaction
The nurse is caring for a client who has diabetes complicated by kidney disease. A detailed
assessment should be done when administering medications because this client may experience
problems with:
A. Absorption
B. Biotransformation
C. Distribution
D. Excretion - answer✔excretion
First Pass Effect - answer✔The intestinal and hepatic degradation or alteration of a drug or
substance taken by mouth, after absorption, removing some of the active substance from the
blood before it enters the general circulation
A drug given via the oral route may be extensively metabolized by the liver before reaching the
systemic circulation (high first-pass effect)
The same drug—given IV—bypasses the liver, preventing the first-pass effect from taking place,
and more drug reaches the circulation
biological half-life - answer✔The time required for half the quantity of a drug or other substance
deposited in a living organism to be metabolized or eliminated by normal biological processes.
The time required for something to fall to half its original value.
A drug's half-life is used to determine how often a drug must be administered in order to
maintain its therapeutic level.
Onset - answer✔the time it takes for the drug to elicit a therapeutic response
