A) Pharmacoeconomics
B) Pharmacotherapeutics

Ans: B
Response:
Pharmacology is the study of the biologic effects of chemicals. Nurses are ss ss ss ss ss ss ss ss ss 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

Pharmacodynamics involves how a drug affects the body, and pharmacokinetics

h ours as needed for pain for a motor vehicle accident victim. The nurse is
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss


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

ssis categorized as a:

A) Schedule I drug ss ss


B) Schedule II drug ss s s


C) Schedule III drug ss s s


D) Schedule IV drug ss ss


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


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


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

abuse potent ial than schedule II drugs and an accepted medical use.

B) Monitoring drug effects in patients who are selected to participate in a ss ss ss ss ss ss ss ss ss ss ss


study, who have the disease that the drug is meant to treat
ss ss ss ss ss ss s s ss ss ss s s ss


C) Collecting records of symptoms that participants experience while taking a ss ss ss ss ss ss ss ss ss


d rug and determining whether they are caused by the disease or the drug
ss ss ss ss ss ss ss ss ss ss ss ss ss ss


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


could occur from taking an experimental drug
ss ss ss ss ss ss ss


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


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


Nurses may be responsible for helping collect and analyze the information
ss ss ss ss ss ss ss ss ss ss ss


to be shared with th e Food and Drug Administration (FDA). Use of
ss ss ss ss ss ss s s ss ss ss ss ss ss


animals in drug testing is done in the preclinical trials. A select group of
ss ss ss ss ss ss ss ss ss ss ss ss ss ss


patients who are involved in phase II studie s participate in studies where the
ss ss ss ss ss ss ss ss ss ss ss ss ss ss


participants have the disease the drug is intended to treat. These patients are
ss ss ss ss ss ss ss ss s s ss ss ss ss


monitored closely for drug effects. Phase I studies invol ve healthy human
ss ss ss ss ss ss ss ss ss ss ss ss


volunteers who are usually paid for their participation. Nurses m ay observe for
ss ss ss ss ss ss ss ss ss ss ss ss ss


adverse effects and toxicity.

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


ssf 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 ss ss ss ss ss ss ss ss ss ss ss ss ss


circulati on and is available to act on body cells. Binders used in a generic drug
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss


may not be the same as those used in the brand-
ss ss ss ss ss ss ss ss ss ss ss


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


differ, which may eliminate a substitution. Critical concentration is the amount
ss ss ss ss ss ss ss ss ss s s ss


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


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


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


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


one- half of the peak level.
