Chapter 01- Introduction to Drugs
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
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

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
