Pharmacology Clear and Simple- A Guide to Drug Classifications and

Dosage Calculations 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
Feedback:

,Pharmacology Clear and Simple- A Guide to Drug Classifications and

Dosage Calculations 3rd Edition Watkins Test Bank


Bioavailability is the portion of a dose of a drug that reaches the
systemic circulation and is available to act on body cells. Binders
used in a generic drug may not be the same as those used in the
brand name drug. Therefore, the way the body breaks down and
uses the drug may differ, which may eliminate a generic drug
substitution. Critical concentration is the amount of a drug that is
needed to cause a therapeutic effect and should not differ between
generic and brand name medications. Distribution is the phase of
pharmacokinetics, which involves the movement of a drug to the
bodys tissues and is the same in generic and brand name drugs. A
drugs half-life is the time it takes for the amount of drug to decrease to
half the peak level, which should not change when substituting a
generic medication.

5. A nurse is assessing the patients home medication use. After
listening to the patient list current medications, the nurse asks what
priority question?
A) Do you take any generic medications?
B) Are any of these medications orphan drugs?
C) Are these medications safe to take during pregnancy?
D) Do you take any over-the-counter medications?
Ans: D
Feedback:
It is important for the nurse to specifically question use of over-the-
counter medications because patients may not consider them
important. The patient is unlikely to know the meaning of orphan
drugs unless they too are health care providers. Safety during
pregnancy, use of a generic medication, or classification of orphan
drugs are things the patient would be unable to answer but could be
found in reference books if the nurse wishes to research them.


6. After completing a course on pharmacology for nurses, what will the
nurse know?
A) Everything necessary for safe and effective medication administration
B) Current pharmacologic therapy; the nurse will not require
ongoing education for 5 years.
C) General drug information; the nurse can consult a drug guide for
specific drug information.
D) The drug actions that are associated with each
classification of medication
