Chapter 01 - Introduction to Medications
A caregiver working in radiology administers iodine to a client who is having a computed tomography
(CT) scan. The caregiver working on the oncology unit administers chemotherapy to clients who
have cancer. At the Public Health Department, a caregiver 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 caregivers?
Pharmacoeconomics
Pharmacotherapeutics
Pharmacodynamics
Pharmacokinetics
CORRECT
CHOICE:- B
Elaborations:->>>
Pharmacology is the study of the biologic effects of chemicals. Caregivers are involved with clinical
pharmacology or pharmacotherapeutics, which is a branch of pharmacology that deals with the uses of
medications to treat, prevent, and diagnose illness. The radiology caregiver is administering a
medication to help diagnose a illness. The oncology caregiver is administering a medication to help
treat a illness.
Pharmacoeconomics includes any costs involved in medication therapy. Pharmacodynamics involves
how a medication 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 caregiver is aware this medication has a high abuse
potential.
Under what category would morphine be classified?
Schedule I
Schedule II
Schedule III
Schedule IV
CORRECT
CHOICE:- B

Elaborations:->>>
Narcotics with a high abuse potential are classified as Schedule II medications because of severe dependence
liability. Schedule I medications have high abuse potential and no accepted medical use. Schedule
III medications have a lesser abuse potential than II and an accepted medical use. Schedule IV
medications have low abusepotential and limited dependence liability.
When involved in phase III medication evaluation studies, what responsibilities would the
caregiver have?Working with animals who are given experimental medications
Choosing appropriate clients to be involved in the medication study
Monitoring and observing clients closely for adverse effects
Conducting research to determine effectiveness of the medication
CORRECT CHOICE:- C
Elaborations:->>>
Phase III studies involve use of a medication in a vast clinical population in which clients are asked to
recordany symptoms they experience while taking the medications. Caregivers may be responsible for
helping collect and analyze the information to be shared with the Food and Medication Administration
(FDA) but would not conduct research independently because caregivers do not prescribe medications.
Use of animals in medication testing is done in the preclinical trials. Select clients who are involved in
phase II studies to participatein studies where the participants have the illness the medication is
intended to treat. These clients are monitored closely for medication action and adverse effects. Phase I
studies involve healthy human volunteers who are usually paid for their participation. Caregivers may
observe for adverse effects and toxicity.
What concept is considered when generic medications are substituted for brand name
medications?Bioavailability
Critical concentration
Distribution
Half-life
CORRECT
CHOICE:- A

Bioavailability is the portion of a dose of a medication that reaches the systemic circulation and is
available to act on body cells. Binders used in a generic medication may not be the same as those used
in the brand name medication. Therefore, the way the body breaks down and uses the medication may
differ, which may eliminate a generic medication substitution. Critical concentration is the amount of a
medication 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
medication to the body’s tissues and is the
same in generic and brand name medications. A medication’s half-life is the time it takes for the
amount of medication todecrease to half the peak level, which should not change when substituting a
generic medication.
A caregiver is assessing the client’s home medication use. After listening to the client list
current medications, the caregiver asks what priority question?
Do you take any generic medications?
Are any of these medications orphan medications?
Are these medications safe to take during pregnancy?
Do you take any over-the-counter medications?
CORRECT CHOICE:- D
Elaborations:->>>
It is important for the caregiver to specifically question use of over-the-counter medications because
clients may not consider them important. The client is unlikely to know the meaning of orphan
medications unless they too are primary care providers. Safety during pregnancy, use of a generic
medication, or classification of orphan medications are things the client would be unable to answer but
could be found in reference books if the caregiver wishes to research them.
After completing a course on pharmacology for caregivers, what will the
caregiver know?Everything necessary for safe and effective medication
administration
Current pharmacologic therapy; the caregiver will not require ongoing education for 5
years. General medication information; the caregiver can consult a medication guide for
specific medication information. The medication actions that are associated with each
classification of medication CORRECT CHOICE:- C
