Pharmacology is the study of the biologic effects of chemicals. Nurses are involved withv v v v v v v v v v v v v




clinical pharmacology or pharmacotherapeutics, which is a branch of pharmacology
v v v v v v v v v v




that deals with the uses of drugs to treat, prevent, and diagnose disease. The
v v v v v v v v v v v v v v




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




nurse is administering a drug to help treat a disease. Pharmacoeconomics includes any
v v v v v v v v v v v v v




vcosts involved in drug therapy. Pharmacodynamics involves how a drug affects the
v v v v v v v v v v v




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

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




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




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




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




low abuse potential and limited dependence liability.

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




would the nurse have?
v v v v




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




B) Choosing appropriate patients to be involved in the drug study v v v v v v v v v




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




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




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




patients are asked to record any symptoms they experience while taking
v v v v v v v v v v v




the drugs. Nurses may be responsible for helping collect and analyze the
v v v v v v v v v v v v




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




vwould not conduct research independently because nurses do not prescribe
v v v v v v v v v




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




vSelect patients who are involved in phase II studies to participate in studies
v v v v v v v v v v v v




vwhere the participants have the disease the drug is intended to treat. These
v v v v v v v v v v v v




vpatients are monitored closely for drug action and adverse effects. Phase I
v v v v v v v v v v v




vstudies involve healthy human volunteers who are usually paid for their
v v v v v v v v v v




vparticipation. Nurses may observe for adverse effects and toxicity. v v v v v v v v

v v v v v v v v v




brand name drugs?
