Test Bank for Karch’s Focus on Nursing Pharmacology
9th Edition by Rebecca Tucker

,Chapter 01 - Introduction to Drugs


A nursing practitioner working in radiology administers iodine to a client who is having a computed
tomography (CT) scan. The nursing practitioner working on the oncology unit administers
chemotherapy to clients who have cancer. At the Public Health Department, a nursing practitioner
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 nursing
practitioners?


Pharmacoeconomics


Pharmacotherapeutics


Pharmacodynamics


Pharmacokinetics


ANSWER✔✔ B


RATIONALE:


Pharmacology is the study of the biologic effects of chemicals. Nursing practitioners 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 nursing practitioner is
administering a drug to help diagnose a disease. The oncology nursing practitioner 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 doctor has ordered intramuscular (IM) injections of morphine, a narcotic, every 4 hours as needed for
pain in a motor vehicle accident victim. The nursing practitioner is aware this drug has a high abuse
potential.
Under what category would morphine be classified?


Schedule I


Schedule II


Schedule III


Schedule IV


ANSWER


✔✔ B

, RATIONALE:


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 nursing


practitioner have? Working with animals who are given experimental drugs


Choosing appropriate clients to be involved in the drug study


Monitoring and observing clients closely for adverse effects


Conducting research to determine effectiveness of the drug


ANSWER✔✔ C


RATIONALE:


Phase III studies involve use of a drug in a vast clinical population in which clients are asked to record
any symptoms they experience while taking the drugs. Nursing practitioners 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 nursing practitioners do not prescribe
medications. Use of animals in drug testing is done in the preclinical trials. Select clients who are
involved in phase II studies to participate in studies where the participants have the disease the drug is
intended to treat. These clients are monitored closely for drug action and adverse effects. Phase I studies
involve healthy human volunteers who are usually paid for their participation. Nursing practitioners
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


ANSWER✔


✔ A


RATIONALE:

, 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
