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?
1|Page
, 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 treata 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 whatcategory 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 havelow abuse potential and limited
dependence liability.
3. When involved in phase III drug evaluation studies, what responsibilitieswould
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 ofa 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 isthe 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 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 specificdrug
information.
D) The drug actions that are associated with each classification of
medication
Ans: C
