,CH 1. Introduction: The Nature of Drugs & Drug Development & Regulation
1. A nurse working in radiology administers iodine to a hospital
client who is having a computed tomography (CT) scan. The
nursing attendant working on the oncology unit administers
chemotherapy to hospital clients who have cancer. At the Public
Health Department, a nursing attendant 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 attendants?
A) Pharmacoeconomics
B) Pharmacotherapeutics
C) Pharmacodynamics
D) Pharmacokinetics
ACCURATE CHOICE:- B
Reasoning :->>>>>>
Pharmacology is the study of the biologic effects of chemicals.
Nursing attendants 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 attendant is administering a drug
to help diagnose a disease. The oncology nursing attendant 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. When involved in phase III drug evaluation
studies, whatresponsibilities would the nursing
attendant have?
A) Working with animals who are given experimental drugs
B) Choosing appropriate hospital clients to be involved in the drug
study
C) Monitoring and observing hospital clients closely for adverse
effects
D) Conducting research to determine effectiveness of the drug
,ACCURATE CHOICE:- C
Reasoning:->>>>>>
Phase III studies involve use of a drug in a vast clinical population
in whichhospital clients are asked to record any symptoms they
experience while taking the drugs. Nursing attendants may be
responsible for helping collect and analyzethe information to be
shared with the Food and Drug Administration (FDA)but would
not conduct research independently because nursing attendants
donot prescribe medications. Use of animals in drug testing is
done in the preclinical trials. Select hospital 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
hospital 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 attendants may
observe for
adverse effects and toxicity.
3. 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 nursing attendant 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
ACCURATE CHOICE:- B
Reasoning:->>>>>>
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 havelow abuse potential and
limited dependence liability.
, 4. What concept is considered when generic drugs are
substituted for brandname drugs?
A) Bioavailability
