1. A nurse working in radiology administers iodine to a patient who is having a
v v v v v v v v v v v v v
computedtomography (CT) scan. The nurse working on the oncology unit administers
v v v v v v v v v v v v
chemotherapy to patients who have cancer. At the Public Health Department, a nurse
v v v v v v v v v v v v v
administers a measles-mumps-rubella (MMR) vaccine to a 14-month-old child as a
v v v v v v v v v v v
routine immunization. Which branch ofpharmacology best describes the actions of all
v v v v v v v v v v v v
three nurses?
v v
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 v v v v v v v v v v v v v
clinical pharmacology or pharmacotherapeutics, which is a branch of pharmacology that
v v v v v v v v v v v
deals with the uses of drugs to treat, prevent, and diagnose disease.The radiology nurse
v v v v v v v v v v v v v v v
is administering a drug to help diagnose a disease. The oncology nurse is administering a
v v v v v v v v v v v v v v v
drug to help treat a disease. Pharmacoeconomics includes any costs involved in drug
v v v v v v v v v v v v v
therapy. Pharmacodynamics involves how a drug affects the body and pharmacokinetics is
v v v v v v v v v v v v
how the body acts on the body.

2. A physician has ordered intramuscular (IM) injections of morphine, a narcotic,
v v v v v v v v v v
every 4 hours as needed for pain in a motor vehicle accident victim. The nurse
v v v v v v v v v v v v v v v
is aware this drug has a high abuse potential. Under whatcategorywould
v v v v v v v v v v v v v
morphine be classified?
v v v
A) Schedule I v
B) Schedule II v
C) Schedule III v
D) Schedule IV v
ANSWER: B
, Feedback:
Narcotics with a high abuse potential are classified as Schedule II drugs because
v v v v v v v v v v v v
of severe dependence liability. Schedule I drugs have high abuse potential and
v v v v v v v v v v v v
no accepted medical use. Schedule III drugs have a lesser abuse potential than
v v v v v v v v v v v v v
II and an accepted medical use. Schedule IV drugs havelow abuse potential and
v v v v v v v v v v v v v v
limited dependence liability.

3. When involved in phase III drug evaluation studies, what
v v v v v v v v
responsibilitieswould the nurse have?
v 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
v v v v v v v v v v v v v
whichpatients are asked to record any symptoms they experience while taking
v v v v v v v v v v v v
thedrugs. 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)
v v v v v v v v v v v
butwould not conduct research independently because nurses do not
v v v v v v v v v v
prescribe medications. Use of animals in drug testing is done in the preclinical
v v v v v v v v v v v v v
trials. Select patients who are involved in phase II studies to participate in
v v v v v v v v v v v v v
studies where the participants have the disease the drug is intended to treat.
v v v v v v v v v v v v v
These patients are monitored closely for drug action and adverse effects.
v v v v v v v v v v v
Phase I studies involve healthy human volunteers who are usually paid for their
v v v v v v v v v v v v v
participation. Nurses may observe for adverse effects and toxicity.
