1. A nurse working in radiology administers iodine to a patient who is having a
b b b b b b b b b b b b b
computedtomography (CT) scan. The nurse working on the oncology unit administers
b b b b b b b b b b b
chemotherapy to patients who have cancer. At the Public Health Department, a nurse
b b b b b b b b b b b b b
administers a measles-mumps-rubella (MMR) vaccine to a 14-month-old child as a
b b b b b b b b b b b
routine immunization. Which branch of pharmacology best describes the actions of all
b b b b b b b b b b b b
three nurses?
b b
A) Pharmacoeconomics
B) Pharmacotherapeutics
C) Pharmacodynamics
D) Pharmacokinetics
ANSWER: B
Feedback:
Pharmacology is the study of the biologic effects of chemicals. Nurses are involved
b b b b b b b b b b b b
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.
b b b b b b b b b b b b b b
The radiology nurse is administering a drug to help diagnose a disease. The oncology
b b b b b b b b b b b b b b
nurse is administering a drug to help treat a disease. Pharmacoeconomics includes any
b b b b b b b b b b b b b
costs involved in drug therapy. Pharmacodynamics involves how a drug affects the
b b b b b b b b b b b b
body and pharmacokinetics is how the body acts on the body.

2. A physician has ordered intramuscular (IM) injections of morphine, a
b b b b b b b b b
narcotic, every 4 hours as needed for pain in a motor vehicle accident
b b b b b b b b b b b b b
victim. The nurse is aware this drug has a high abuse potential. Under what
b b b b b b b b b b b b b b
category would morphine be classified?
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
have low abuse potential and limited dependence liability.

3. When involved in phase III drug evaluation studies, what responsibilities
b b b b b b b b b
would the nurse have?
b b b b
A) Working with animals who are given experimental drugs
b b b b b b b
B) Choosing appropriate patients to be involved in the drug study
b b b b b b b b b
C) Monitoring and observing patients closely for adverse effects
b b b b b b b
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 which
b b b b b b b b b b b b b b
patients are asked to record any symptoms they experience while taking the
b b b b b b b b b b b b
drugs. Nurses may be responsible for helping collect and analyze the
b b b b b b b b b b b
information to be shared with the Food and Drug Administration (FDA)
b b b b b b b b b b b
but would 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
b b b b b b b b b b b b
intended to treat. These patients are monitored closely for drug action and
b b b b b b b b b b b b
adverse effects. Phase I studies involve healthy human volunteers who are
b b b b b b b b b b b
usually paid for their participation. Nurses may observe for adverse effects

and toxicity.
