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
,Test bank Focus on Nursing Pharmacology 7th edition
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
,Test bank Focus on Nursing Pharmacology 7th edition
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:
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
body’s tissues and is the
same in generic and brand name drugs. A drug’s 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 patient’s home medication use. After
