A) Pharmacoeconomics

B) Pharmacotherapeutics

C) Pharmacodynamics

D) Pharmacokinetics

Ans: B

Feedback:

Pharmacology is the study of the biologic effects of chemicals. Nurses are i
f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5


nvolved with clinical pharmacology or pharmacotherapeutics, which is a bra
f5 f5 f5 f5 f5 f5 f5 f5 f5


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

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

ose a disease. The oncology nurse is administering a drug to help treat adise

ase. Pharmacoeconomics includes any costs involved in drug therapy.
f5 f5 f5 f5 f5 f5 f5 f5


Pharmacodynamics involves how a drug affects the body an f5 f5 f5 f5 f5 f5 f5 f5


dpharmacokinetics is how the body acts on the body.

C) Schedule III f5




D) Schedule IV f5




Ans: B

Feedback:

Narcotics with a high abuse potential are classified as Schedule II drugs be
f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5


cause of severe dependence liability. Schedule I drugs have high abuse pot
f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5


ential and no accepted medical use. Schedule III drugs have a lesser abuse
f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5


potential than II and an accepted medical use. Schedule IV drugs havelow
f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 5f f5


abuse potential and limited dependence liability.

3.
When involved in phase III drug evaluation studies, what responsibilit
f5 f5 f5 f5 f5 f5 f5 f5 f5


ieswould the nurse have?
5f f5 f5 f5




A) Working with animals who are given experimental drugs
f5 f5 f5 f5 f5 f5 f5




B) Choosing appropriate patients to be involved in the drug study
f5 f5 f5 f5 f5 f5 f5 f5 f 5




C) Monitoring and observing patients closely for adverse effects
f5 f5 f5 f5 f5 f5 f5




D) Conducting research to determine effectiveness of the drug
f5 f5 f5 f5 f5 f5 f5




Ans: C

Feedback:

Phase III studies involve use of a drug in a vast clinical population in whic
f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5


hpatients are asked to record any symptoms they experience while taking t

hedrugs. Nurses may be responsible for helping collect and analyze the inf

ormation to be shared with the Food and Drug Administration (FDA) butw
f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 f5 5f


ould not conduct research independently because nurses do not prescribe
f5 f5 f5 f5 f5 f5 f5 f5 f5 f5


medications. Use of animals in drug testing is done in the preclinical trials.
