Pharmacology is the study of the biologic effects of chemicals. Nurses are ss ss ss ss s s ss ss ss s s ss ss



involve d with clinical pharmacology or pharmacotherapeutics, which is a branch
ss ss ss ss ss ss ss ss ss ss ss



of pharm acology that deals with the uses of drugs to treat, prevent, and diagnose

disease. T he nurse working in radiology is administering a drug to help diagnose a

ours as needed for pain for a motor vehicle accident victim. The nurse is aware that
ss ss ss s s ss ss ss ss ss ss ss ss ss ss ss ss



there is a high abuse potential for this drug; therefore, morphine is

categorized as a:

B) Schedule II drug ss s s



C) Schedule III drug s s s s



D) Schedule IV drug ss s s



Ans: B
Response:
Narcotics such as morphine are considered schedule II drugs because of the high a
ss ss ss ss ss ss ss ss ss ss ss ss ss



buse potential with severe dependence liability. Schedule I drugs have high abuse p
ss ss ss ss ss ss ss ss ss ss ss ss ss



otential and no accepted medical use. Schedule III drugs have a lesser abuse

drugs have lo w abuse potential and limited dependence liability.

D) rming healthy, young volunteer participants of possible risks that could occur
ss ss ss ss ss ss ss ss ss ss ss



from taking an experimental drug
ss ss ss ss ss



Ans: C
Response:
Phase III studies involve use of a drug in a vast clinical market where patients are
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss



asked to record any symptoms they experience while taking the drugs. Nurses may
ss ss ss ss ss ss ss ss ss ss ss ss ss



be responsible for helping collect and analyze the information to be shared
ss ss ss ss ss s s s s ss ss ss ss ss



with th e Food and Drug Administration (FDA). Use of animals in drug testing
s s ss ss s s s s s s ss ss ss ss ss ss ss ss



is done in the preclinical trials. A select group of patients who are involved in
ss ss ss ss ss ss ss ss ss ss ss ss ss ss s s

4. Which of the following concepts is considered when generic drugs are substituted f
ss ss ss ss ss ss s s ss ss ss ss s s



or brand-name drugs?
ss ss ss



A) Bioavailability
B) Critical concentration ss



C) Distribution
D) Half-life
Ans: A
Response:
Bioavailability is the portion of a dose of a drug that reaches the systemic circulati ss ss ss ss ss ss ss ss ss ss ss ss ss ss



on and is available to act on body cells. Binders used in a generic drug may not be
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss



the same as those used in the brand-
ss ss ss ss ss ss ss ss



name drug. Therefore, the way the body breaks down and uses the drug may differ,
ss ss ss ss ss ss ss ss ss s s ss ss ss ss



which may eliminate a substitution. Critical concentration is the amount of a drug
ss ss ss ss ss ss ss ss s s ss ss s s ss



that is needed to cause a therapeutic effect.
ss ss ss s s ss ss ss ss



Distribution is the phase of pharmacokinetics that involves the movement of a drug ss ss ss ss ss ss ss ss ss ss ss ss



to the body's tissues. A drug's half-
ss ss ss ss ss ss ss



life is the time it takes for the amount of drug to decrease to one-
ss ss ss ss ss ss ss ss ss s s ss ss ss ss



half of the peak level.
