A nurse working in radiology administers iodine to a patient who is having a
computed tomography (CT) scan. The nurse working on the oncology unit admini
sters chemotherapy to patients who have cancer. At the Public Health Department
, a nurse administers a measles-mumps-rubella (MMR) vaccine to a 14-month-
old child as a routine immunization. Which branch of pharmacology best describe
s the actions of all three nurses?
A) Pharmacoeconomics
B) Pharmacotherapeutics
C) Pharmacodynamics
D) Pharmacokinetics
ANSWER: B
Feedback:
Pharmacology is the study of the biologic effects of chemicals. Nurses are involv
ed with clinical pharmacology or pharmacotherapeutics, which is a branch of pha
rmacology that deals with the uses of drugs to treat, prevent, and diagnose disea
se. The radiology nurse is administering a drug to help diagnose a disease. The o
ncology nurse is administering a drug to help treat a disease. Pharmacoeconomic
s includes any costs involved in drug therapy. Pharmacodynamics involves how a
drug affects the body and pharmacokinetics is how the body acts on the body.

A physician has ordered intramuscular (IM) injections of morphine, a
narcotic, every 4 hours as needed for pain in a motor vehicle acciden
t victim. The nurse is aware this drug has a high abuse potential. Und
er what category would morphine be classified?
A) Schedule I
B) Schedule II
C) Schedule III
D) Schedule IV
ANSWER: B
, Feedback:
Narcotics with a high abuse potential are classified as Schedule II drugs
because of severe dependence liability. Schedule I drugs have high abu
se potential and no accepted medical use. Schedule III drugs have a les
ser abuse potential than II and an accepted medical use. Schedule IV dr
ugs have low abuse potential and limited dependence liability.
3.
When involved in phase III drug evaluation studies, what responsi
bilities would the nurse have?
A) Working with animals who are given experimental drugs
B) Choosing appropriate patients to be involved in the drug study
C) Monitoring and observing patients closely for adverse effects
D) Conducting research to determine effectiveness of the drug
ANSWER: C
Feedback:
Phase III studies involve use of a drug in a vast clinical population in
which patients are asked to record any symptoms they experience while
taking the drugs. Nurses may be responsible for helping collect and anal
yze the information to be shared with the Food and Drug Administratio
n (FDA) but would not conduct research independently because nurses d
o not prescribe medications. Use of animals in drug testing is done in t
he preclinical trials. Select patients who are involved in phase II studies
to participate in studies where the participants have the disease the dru
g is intended to treat. These patients are monitored closely for drug acti
on and adverse effects. Phase I studies involve healthy human volunteer
s who are usually paid for their participation. Nurses may observe for a
dverse effects and toxicity.
