Chapter 01 - Introduction to drugs
A medical attendant working in radiology administers iodine to a hospital client who is having a
computed tomography (CT)scan. The medical attendant working on the oncology unit
administers chemotherapy to hospital clients who have cancer. At the Public Health Department,
a medical 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 medical attendants?
Pharmacoeconomics
Pharmacotherapeutics
Pharmacodynamics
Pharmacokinetics
ACCURATE ANS:-
B
Reasoning:->>>
Pharmacology is the study of the biologic effects of chemicals. Medical 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 sickness. The radiology medical attendant is administering
a drug to help diagnose a sickness. The oncology medical attendant is administering a drug to help
treat a sickness.
Pharmacoeconomics includes any costs involved in drug therapy. Pharmacodynamics involveshow 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 needed for
pain in a motor vehicle accident victim. The medical attendant is aware this drug has a high abuse
potential.
Under what category would morphine be classified?
Schedule I
Schedule II
Schedule III
Schedule IV

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
have low abusepotential and limited dependence liability.
When involved in phase III drug evaluation studies, what responsibilities would the medical
attendant have?Working with animals who are given experimental drugs
Choosing appropriate hospital clients to be involved in the drug
studyMonitoring and observing hospital clients closely for adverse
effects Conducting research to determine effectiveness of the drug
ACCURATE ANS:- C
Reasoning:->>>
Phase III studies involve use of a drug in a vast clinical population in which hospital clients are asked
to recordany symptoms they experience while taking the drugs. Medical attendants 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 medical attendants do
not prescribe drugs.Use of animals in drug testing is done in the preclinical trials. Select hospital
clients who are involved in phase II studies to participatein studies where the participants have the
sickness the drug is intended to treat. These hospital clients are monitored closely for drug action and
adverse effects. Phase Istudies involve healthy human volunteers who are usually paid for their
participation. Medical attendants 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

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 brandname drugs. 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
todecrease to half the peak level, which should not change when substituting a generic drug.
A medical attendant is assessing the hospital client’s home drug use. After listening to the
hospital client list present drugs, the medical attendant asks what priority question?
Do you take any generic drugs?
Are any of these drugs orphan drugs? Are these
drugs safe to take during expectancy?Do you take any
over-the-counter drugs?
ACCURATE ANS:-D
Reasoning:->>>
It is important for the medical attendant to specifically question use of over-the-counter drugs because
hospital clients may not consider them important. The hospital client is unlikely to know the meaning
of orphan drugsunless they too are primary care providers. Safety during expectancy, use of a generic
drug, or classification of orphan drugs are things the hospital client would be unable to answer but
could be found in reference books if the medical attendant wishes to research them.
After completing a course on pharmacology for medical attendants, what will
the medical attendant know?Everything necessary for safe and effective drug
administration
Present pharmacologic therapy; the medical attendant will not require ongoing
education for 5 years. General drug information; the medical attendant can consult a
drug guide for specific drug information.The drug actions that are associated with each
classification of drug ACCURATE ANS:- C
