,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
2|Page
, 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 thedrugs. Nurses may be responsible for helping collect and
analyze the information to be shared with the Food and Drug
Administration (FDA) butwould 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
brandname drugs?
A) Bioavailability
B) Critical concentration
C) Distribution
D) Half-life
Ans: A
Feedback:
3|Page
, 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 thepatient 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 researchthem.
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 ofmedication
Ans: C
