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

2. A physician has ordered intramuscular (IM) injections of morphine, a
n n n n n n n n n
narcotic, every 4 hours as needed for pain in a motor vehicle accident victim.

The nurse is aware this drug has a high abuse potential. Under whatcategory
n n n n n n n n n n n n n n
would morphine be classified?
n n n n
A) Schedule I n
B) Schedule II n
C) Schedule III n
D) Schedule IV n
ANSWER: B
, Feedback:
Narcotics with a high abuse potential are classified as Schedule II drugs because
n n n n n n n n n n n n
of severe dependence liability. Schedule I drugs have high abuse potential and
n n n n n n n n n n n n
no accepted medical use. Schedule III drugs have a lesser abuse potential than
n n n n n n n n n n n n n
II and an accepted medical use. Schedule IV drugs havelow abuse potential
n n n n n n n n n n n n n
and limited dependence liability.

3. When involved in phase III drug evaluation studies, what responsibilities
n n n n n n n n n
would the nurse have?
n n n n
A) Working with animals who are given experimental drugs n n n n n n n
B) Choosing appropriate patients to be involved in the drug study n n n n n n n n n
C) Monitoring and observing patients closely for adverse effects n n n n n n n
D) Conducting research to determine effectiveness of the drug n n n n n n n
ANSWER: C
Feedback:
Phase III studies involve use of a drug in a vast clinical population in which
n n n n n n n n n n n n n n
patients are asked to record any symptoms they experience while taking the
n n n n n n n n n n n n
drugs. Nurses may be responsible for helping collect and analyze the
n n n n n n n n n n n
information to be shared with the Food and Drug Administration (FDA) but
n n n n n n n n n n n n
would not conduct research independently because nurses do not prescribe
n n n n n n n n n n
medications. Use of animals in drug testing is done in the preclinical trials.

Select patients who are involved in phase II studies to participate in studies
n n n n n n n n n n n n n
where the participants have the disease the drug is intended to treat. These
n n n n n n n n n n n n n
patients are monitored closely for drug action and adverse effects. Phase I
n n n n n n n n n n n n
studies involve healthy human volunteers who are usually paid for their
n n n n n n n n n n n
participation. Nurses may observe for adverse effects and toxicity.
