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
Accurate Answer: 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 what
Do
category would morphine be classified?
A) Schedule I
c
B) Schedule II
C) Schedule III
D) Schedule IV
Accurate Answer: 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
3
, 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
Accurate Answer: 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
Ar
B) Critical concentration
C) Distribution
ch
D) Half-life
Do
Accurate Answer: A
Feedback:
c
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?
