1. A nurse working in radiology administers iodine to a patient who is having a computed
f f f f f f f f f f f f f f




tomography (CT) scan. The nurse working on the oncology unit administers
f f f f f f f f f f f




chemotherapy to patients who have cancer. At the Public Health Department, a nurse
f f f f f f f f f f f f f




administers a measles-mumps-rubella (MMR) vaccine to a 14-month-old child as a
f f f f f f f f f f f




routine immunization. Which branch of pharmacology best describes the actions of all
f f f f f f f f f f f f




three nurses?
f f




A) Pharmacoeconomics
B) Pharmacotherapeutics
C) Pharmacodynamics
D) Pharmacokinetics
ANSWER: B
Feedback:
Pharmacology is the study of the biologic effects of chemicals. Nurses are involved with f f f f f f f f f f f f f




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




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




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




administering a drug to help treat a disease. Pharmacoeconomics includes any costs
f f f f f f f f f f f f




involved in drug therapy. Pharmacodynamics involves how a drug affects the body and
f f f f f f f f f f f f f




pharmacokinetics is how the body acts on the body.

2. A physician has ordered intramuscular (IM) injections of morphine, a
f f f f f f f f f




narcotic, every 4 hours as needed for pain in a motor vehicle accident victim.
f f f f f f f f f f f f f f




The nurse is aware this drug has a high abuse potential. Under whatcategory
f f f f f f f f f f f f f f




would morphine be classified?
f f f f




A) Schedule I f




B) Schedule II f




C) Schedule III f




D) Schedule IV f




ANSWER: B

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




of severe dependence liability. Schedule I drugs have high abuse potential and
f f f f f f f f f f f f




no accepted medical use. Schedule III drugs have a lesser abuse potential
f f f f f f f f f f f f




than II and an accepted medical use. Schedule IV drugs havelow abuse
f f f f f f f f f f f f f




potential and limited dependence liability.

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




would the nurse have?
f f f f




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




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




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




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




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




patients are asked to record any symptoms they experience while taking the
f f f f f f f f f f f f




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




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




would not conduct research independently because nurses do not prescribe
f f f f f f f f f f




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




Select patients who are involved in phase II studies to participate in studies
f f f f f f f f f f f f f




where the participants have the disease the drug is intended to treat. These
f f f f f f f f f f f f f




patients are monitored closely for drug action and adverse effects. Phase I
f f f f f f f f f f f f




studies involve healthy human volunteers who are usually paid for their
f f f f f f f f f f f




participation. Nurses may observe for adverse effects and toxicity.
