Pharmacotherapeutics for Advanced Practice
Nurse Prescribers with Davis Edge
6th Edition
Foundational Principles of APN Prescribing
1. Reference: Ch. 1, Section: The Role of the Nurse Practitioner
as Prescriber
Question Stem: A newly licensed Advanced Practice Nurse
(APN) is reviewing the legal foundation of their prescriptive
authority before establishing their first clinical position. Which
source provides the most authoritative and specific framework
governing the APN's prescribing practices?
Options:
A. Federal Drug Scheduling regulations under the Controlled
Substances Act
B. Clinical practice guidelines from national professional nursing
organizations
C. The individual APN's collaborative practice agreement with a
physician
D. The Nurse Practice Act and related administrative rules of the
state where the APN is licensed
Correct Answer: D
Rationales:
, • Correct: While federal laws and collaborative agreements
are important, the specific scope of prescriptive authority
for an APN, including which drugs may be prescribed and
under what conditions, is primarily defined and regulated
by the individual state's Nurse Practice Act and its
accompanying rules .
• Incorrect A: Federal drug scheduling controls the
categorization of certain medications but does not grant
the authority to prescribe; that power is state-derived.
• Incorrect B: Professional guidelines provide
recommendations for best practices but are not legally
binding authority for prescribing.
• Incorrect C: A collaborative agreement may be required by
a state's law, but it operates within the scope defined by
the state's Nurse Practice Act, which is the ultimate legal
authority.
Teaching Point: Prescriptive authority is primarily granted and
regulated by individual state law.
2. Reference: Ch. 1, Section: Rational Drug Selection
Question Stem: An APN is selecting a first-line antihypertensive
medication for a newly diagnosed patient. The decision is based
on current clinical guidelines, the drug's safety profile, and the
patient's financial constraints. This process best exemplifies
which of the following core principles of prescribing?
,Options:
A. Pharmacokinetic tailoring
B. Rational drug selection
C. Patient adherence forecasting
D. Pharmaceutical cost-containment
Correct Answer: B
Rationales:
• Correct: Rational drug selection is a systematic process
that involves choosing the most appropriate medication
based on patient-specific factors, clinical evidence, safety,
and cost .
• Incorrect A: While pharmacokinetics might be considered,
this process describes a broader, multi-factorial decision-
making approach.
• Incorrect C: Adherence is an important outcome but not
the name of the initial selection process itself.
• Incorrect D: Cost is one component, but the process
described is comprehensive and not solely focused on
expense.
Teaching Point: Rational drug selection integrates evidence,
patient factors, and cost to determine the optimal therapy.
3. Reference: Ch. 1, Section: Review of the Basic Principles of
Pharmacology
, Question Stem: When considering the prescription of a new
medication, an APN evaluates the drug's intended therapeutic
effects and its potential for causing harmful or unwanted
effects. What is the correct pharmacological term for the
relationship between these desired and undesired effects?
Options:
A. Therapeutic index
B. Dose-response curve
C. Risk-benefit ratio
D. Potency and efficacy
Correct Answer: A
Rationales:
• Correct: The therapeutic index quantitatively describes the
margin of safety of a drug by comparing the dose that
produces a toxic effect in 50% of the population to the
dose that produces a therapeutic effect in 50% of the
population.
• Incorrect B: A dose-response curve illustrates the
relationship between the dose and the magnitude of the
effect, but it does not specifically contrast therapeutic and
adverse effects.
• Incorrect C: Risk-benefit ratio is a clinical decision-making
concept, but it is not the specific pharmacological term for
the relationship between a drug's toxic and therapeutic
doses.
