three nurses?

ANSWER: B
Feedback:
Pharmacology is the study of the biologic effects of chemicals. Nurses are involved

with clinical pharmacology or pharmacotherapeutics, which is a branch of
b b b b b b b b b b



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

disease.The radiology nurse is administering a drug to help diagnose a disease. The
b b b b b b b b b b b b b b



oncology nurse is administering a drug to help treat a disease. Pharmacoeconomics
b b b b b b b b b b b b



includes any costs involved in drug therapy. Pharmacodynamics involves how a drug

affects the body and pharmacokinetics is how the body acts on the body.

whatcategory would morphine be classified?
b b b b b b




A) Schedule I b




B) Schedule II b




C) Schedule III b




D) Schedule IV b




ANSWER: B

, Feedback:
Narcotics with a high abuse potential are classified as Schedule II drugs
b b b b b b b b b b b



because of severe dependence liability. Schedule I drugs have high abuse
b b b b b b b b b b b



potential and no accepted medical use. Schedule III drugs have a lesser
b b b b b b b b b b b b



abuse potential than II and an accepted medical use. Schedule IV drugs
b b b b b b b b b b b b



havelow abuse potential and limited dependence liability.

3. When involved in phase III drug evaluation studies, what

responsibilitieswould the nurse have?

D) Conducting research to determine effectiveness of the drug b b b b b b b




ANSWER: C
Feedback:
Phase III studies involve use of a drug in a vast clinical population in
b b b b b b b b b b b b b



whichpatients are asked to record any symptoms they experience while

taking thedrugs. Nurses may be responsible for helping collect and analyze

the information to be shared with the Food and Drug Administration (FDA)
b b b b b b b b b b b b



butwould not conduct research independently because nurses do not
b b b b b b b b b b



prescribe medications. Use of animals in drug testing is done in the
b b b b b b b b b b b b



preclinical trials. Select patients who are involved in phase II studies to
b b b b b b b b b b b b



participate in studies where the participants have the disease the drug is

intended to treat. These patients are monitored closely for drug action and

adverse effects. Phase I studies involve healthy human volunteers who are
