Chapter 01 - Introduction to Drugs
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?
Pharmacoeconomics
Pharmacotherapeutics
Pharmacodynamics
, 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.
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?
Schedule 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

, 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
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.
A nurse is assessing the patient’s home medication use. After listening to the patient list current
medications, the nurse asks what priority question?
Do you take any generic medications?
Are any of these medications orphan drugs?
Are these medications safe to take during pregnancy?
Do you take any over-the-counter medications?
