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?

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.
A physician has ordered intramuscular (IM) injections of morphine, a narcotic, every 4 hours as
neededfor 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?
Sched
ule I
Schedule II
Schedule
III
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.
When involved in phase III drug evaluation studies, what responsibilities would the nurse
have? Working with animals who are given experimental drugs
Choosing appropriate patients to be involved in the drug study
Monitoring and observing patients closely for adverse effects
Conducting research to determine effectiveness of the drugAns: 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.
What concept is considered when generic drugs are substituted for brand name drugs?
Bioavailability
Critical
concentration
Distribution
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
