name - Answer The drug's safety, effectiveness, and selectivity
What is the objective of drug therapy?
- To provide maximum benefit with minimum harm
- To administer a drug with no side effects
- To administer an ideal drug
- To provide a drug that is quite costly - Answer To provide maximum benefit with minimum
harm

- The pharmacist
- The health unit coordinator
- The nurse - Answer The nurse
Applying the nursing process in drug therapy is directed at
,- choosing what drug is administered
- individualizing drug treatment
- determining effectiveness of drug treatment
- identifying high-risk patients - Answer individualizing drug treatment
Which governmental agency is primarily responsible for regulating drug safety?
- U.S. Department of Health and Human Services
- Drug Enforcement Administration (DEA)
- Food and Drug Administration (FDA)
- U.S. Adopted Names Council - Answer Food and Drug Administration (FDA)
Which is the most reliable way to objectively assess drug efficacy and safety?
- The double-blinded clinical trial
- Usability testing
- The randomized controlled trial
- Clinical testing - Answer The randomized controlled trial
An enteric-coated preparation of a drug dissolves
- in the stomach
- in the intestine
- in the esophagus
- in the mouth - Answer in the intestine
The study of what drugs do to the body and how they do it is called
- pharmacodynamics
- pharmacokinetics
- pharmacology
- the therapeutic index - Answer pharmacodynamics
Drugs that mimic the body's own regulatory molecules are called
,- partial agonists
- antagonists
- agonists
- antibiotics - Answer agonists
The study of drug movement throughout the body is
- pharmacokinetics
- pharmacodynamics
- therapeutics
- clinical pharmacology - Answer pharmacokinetics
The correct order of the four basic pharmacokinetic processes is
- absorption, metabolism, excretion, distribution
- distribution, metabolism, excretion, absorption
- absorption, distribution, metabolism, excretion
- metabolism, absorption, distribution, excretion - Answer absorption, distribution,
metabolism, excretion
This route of administration of a drug offers no barriers to absorption.

- intravenous (IV)
- subcutaneous (subcu) - Answer intravenous (IV)
What prevents drugs from passing between cells in the walls of the capillaries in the central
nervous system (CNS)?
- tight junctions between cells
- decreased permeability
- the ability of the drug to exit the vascular system
- low regional blood flow - Answer tight junctions between cells
, If a drug has a wide therapeutic index it
- is relatively easy to use safely
- should only be given to adults
- should only be given to pediatric patients
- is difficult to use safely - Answer is relatively easy to use safely
Most drug metabolism takes place in the
- stomach
- intestines
- kidneys
- liver - Answer liver
For a drug with a long half-life, what may be necessary to achieve plateau quickly?
- administer the drug more frequently
- administer a loading dose of the drug
- administer more of the drug
- administer a reduced dose of the drug - Answer administer a loading dose of the drug
What makes selective drug action possible?
- receptors
- proteins
- channels
- enzymes - Answer receptors
Which disease primarily can reduce drug excretion?
- liver disease
- kidney disease
- electrolyte imbalances
- pharmacodynamic tolerance - Answer kidney disease
