CLINICAL DRUG THERAPY FINAL PAPER
2026 EXAM Q AND A STUDY GUIDE
COMPLETE QUESTIONS AND ANSWERS
●● 1.2 The nurse is taking care of a man who is confused about the
different medications he is prescribed. He notes that some of the drug
names have changed over the course of time he has been taking them.
When counseling him, it is most important to keep the following
statement in mind:
A. A drug can belong to only one group or classification.
B. A prototype drug is the standard by which similar drugs are
compared.
C. Drug groups and prototypes change frequently, and knowledge about
a prototype cannot guide knowledge about other drugs in the same class.
D. The generic name of a drug changes among manufacturers..
Answer: B.
Rationale: The first drug to be developed in a group is usually
considered the prototype or main example of the group, and similar
drugs that are developed later are compared to the prototype. Knowledge
of the prototype drug can help the nurse understand the actions of other
drugs in the class. Most drugs can belong to multiple groups (e.g., a
therapeutic group, a chemical group), depending on various
characteristics. Drug groups and prototypes are usually quite stable, and
most new drugs fit into a known classification. The trade or brand name
changes among manufacturers, but the generic name stays the same.
,●● 1.3 In understanding the use of controlled substances for patients, it
is important that the nurse knows that controlled drugs are
A. categorized according to prescription or nonprescription status
B. regulated by state and local laws more than federal laws
C. those that must demonstrate high standards of safety
D. scheduled according to medical use and potential for abuse.
Answer: D.
Rationale: Controlled or scheduled drugs are categorized by federal law
according to use and abuse potential. These drugs have regulations that
govern prescribing, dispensing, administering, and record-keeping.
Almost all scheduled drugs require prescriptions (i.e., cannot legally be
sold over the counter). Basic laws are federal, and states and local
communities may enact additional laws.
●● 1.4 A patient is asking what the difference is between a prescription
for 800 mg of a medication that can be purchased on an OTC basis as a
200-mg tablet. To address this issue, it is important that the nurse knows
that OTC drugs
A. are considered safe for any consumer to use
B. are not available for treatment of most commonly occurring
symptoms
C. often differ in indications for use and recommended dosages from
their prescription versions
D. are paid for by most insurance policies.
,Answer: C.
Rationale: Uses may be different, and recommended dosages of over-
the-counter (OTC) drugs are usually lower than prescription versions.
Labels of OTC drugs contain a listing of people who should not use the
drugs, and the drugs are not safe for everyone. Many OTC drugs are
available to treat cold symptoms, heartburn, constipation, and other
common problems. Insurance companies do not pay for OTC drugs.
●● 1.5 A man is very upset with a drug recall of a medication he has
been taking for a long time. He states that he feels like he can no longer
trust anyone to protect him. In response to his questions about the
process of drug development, it is important to know that with a new
drug, the U.S. Food and Drug Administration (FDA) is responsible for
A. testing the drug with animals
B. testing the drug with healthy people
C. marketing the drug to health care providers
D. evaluating the drug for safety and effectiveness.
Answer: D.
Rationale: The U.S. Food and Drug Administration reviews studies
reported by others, mainly pharmaceutical companies, and determines
whether a drug is sufficiently safe and effective to be marketed. The
drug manufacturer is responsible for testing the drug (in animals and
people) and marketing the drug.
●● 1.6 Error-reduction strategies during medication administration
include which of the following? (Select all that apply.)
, A. quiet zone signs at entrance to the medication room
B. protocols and checklist outlining medication administration
C. wearing of a sash or vest to signal others to avoid interruptions of the
nurse during medication administration
D. carrying several patients' prescanned medications on a tray.
Answer: A, B, and C.
Rationale: All of these strategies, except for carrying several clients'
prescanned medications on a cart, potentially reduce the risk of
medication error. The work-around of removing more than one client's
medication from an automated medication dispensing system could lead
to the administration of the wrong medication to a client.
●● 2.1 A nurse practitioner (NP) has just changed a patient's medication
from an oral form to a patch formulation to avoid the first-pass effect.
The NP has explained it to the patient, but the patient still has questions
and asks the nurse to explain again what is meant by the first-pass effect.
The nurse would be most correct in explaining that this has to do with
how
A. drugs initially bind to plasma proteins
B. initial renal function is involved in drug excretion
C. the way drugs first reach their target cells
D. initial metabolism of an oral drug occurs before it reaches the
systemic circulation.
Answer: D.
