Pharmacology Clear and Simple- A Guide to Drug Classifications and
DosageCalculations 3rd Edition Watkins Test Bank
Chapter 1. History of Pharmacology
1. 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 administers 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 describes the actions of all three nurses?
A) Pharmacoeconomics
B) Pharmacotherapeutics
C) Pharmacodynamics
D) Pharmacokinetics
Ans: B
Feedback:
Pharmacology is the study of the biologic effects of chemicals.
Nurses are involved with clinical pharmacology or
pharmacotherapeutics, which is a branch of pharmacology that
deals with the uses of drugs to treat, prevent, and diagnose
disease. The radiology nurse is administering a drug to help
diagnose a disease. The oncology nurse is administering a drug
to help treat a disease. Pharmacoeconomics 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.
2. A physician has ordered intramuscular (IM) injections of
morphine, a 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 what category would
morphine be classified?
A) Schedule I
B) Schedule II
C) Schedule III
,D) Schedule IV
Ans: B
, Feedback:
Narcotics with a high abuse potential are classified as Schedule
II drugs because of severe dependence liability. Schedule I
drugs have high abuse potential and no accepted medical use.
Schedule III drugs have a lesser abuse potential than II and an
accepted medical use. Schedule IV drugs have low abuse
potential and limited dependence liability.
3. When involved in phase III drug evaluation studies, what
responsibilities 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
Ans: 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 analyze the information to
be shared with the Food and Drug Administration (FDA) but
would not conduct research independently because nurses do
not prescribe 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 where the
participants have the disease the drug is intended to treat.
These patients are monitored closely for drug action and
adverse effects. Phase I studies involve healthy human
volunteers who are usually paid for their participation. Nurses
may observe for adverse effects and toxicity.
4. What concept is considered when generic drugs are
substituted for brand name drugs?
A) Bioavailability
B) Critical concentration
C) Distribution
D) Half-life
Ans: A
