Chapter 1: Prescriptive Authority
1) An APRN works in a urology clinic under the supervision of a physician who does not
restrict the types of medications the APRN is allowed to prescribe. State law does not
require the APRN to practice under physician supervision. How would the APRN's
prescriptive authority be described?
A) Full authority
B) Independent
C) Without limitation
D) Limited authority
Correct Answer: B
The APRN has independent prescriptive authority because the regulating body does not
require that the APRN work under physician supervision. Full prescriptive authority gives
the provider the right to prescribe independently and without limitation, while limited
authority places restrictions on the types of drugs that can be prescribed .
2) Which factors increase the need for APRNs to have full prescriptive authority?
A) More patients will have access to health care
B) Enrollment in medical schools is predicted to decrease
C) Physician's assistants are being utilized less often
D) APRN education is more complex than education for physicians
Correct Answer: A
Implementation of the Affordable Care Act has increased the number of individuals with
health care coverage, thus increasing the number of patients who require access to health
care services. The increase in patient numbers creates the need for more providers with
prescriptive authority. APRNs can fill this practice gap .
3) Which factors could be attributed to limited prescriptive authority for APRNs?
(Select all that apply)
A) Inaccessibility of patient care
B) Higher health care costs
C) Higher quality medical treatment
, Page|3
D) Improved collaborative care
E) Enhanced health literacy
Correct Answer: A, B
Limiting prescriptive authority for APRNs can create barriers to quality, affordable, and
accessible patient care. It may also lead to poor collaboration among providers and higher
health care costs. Enhanced health literacy and improved collaborative care are not
directly impacted by limited prescriptive authority .
4) Which aspects support the APRN's provision for full prescriptive authority? (Select
all that apply)
A) Clinical education includes prescription of medications and disease processes
B) Federal regulations support the provision of full authority for APRNs
C) National examinations provide validation of the APRN's ability to provide safe care
D) Licensure ensures compliance with health care and safety standards
E) Limiting provision can decrease health care affordability
Correct Answer: A, C, D
APRNs are educated to practice and prescribe independently without supervision. National
examinations validate their ability to provide safe and competent care. Licensure ensures
compliance with standards that promote public health and safety. Limited prescriptive
authority creates barriers to quality, affordable, and accessible patient care .
5) What is the primary benefit of APRNs having full prescriptive authority?
A) Increased job satisfaction
B) Improved patient outcomes
C) Decreased need for collaboration
D) Reduced medication costs
Correct Answer: B
Full prescriptive authority allows APRNs to make timely decisions regarding patient care,
leading to improved patient outcomes. While job satisfaction and reduced medication
costs may also be benefits, the primary focus is on patient outcomes .

6) Which of the following describes a challenge faced by APRNs seeking full
prescriptive authority?
A) Increased demand for primary care services
B) Variability in state regulations
C) Enhanced education programs
D) Collaboration with physicians
Correct Answer: B
Variability in state regulations can create challenges for APRNs seeking full prescriptive
authority, as laws differ regarding what APRNs are allowed to prescribe and under what
circumstances .
Chapter 2: Pharmacokinetics and Pharmacodynamics
7) A drug with a high first-pass effect will most likely require:
A) No dosage adjustment
B) Increased oral dose
C) Decreased oral dose
D) Parenteral administration
Correct Answer: D
A high first-pass effect significantly reduces bioavailability, often necessitating parenteral
routes to ensure adequate serum concentrations. The liver metabolizes a large portion of
the drug before it reaches systemic circulation when given orally .
8) A patient is initiated on an intravenous infusion of a medication with a 12-hour half-
life. Assuming standard pharmacokinetics and the absence of a loading dose, at what
time will the patient FIRST reach a clinical steady-state concentration?
A) 12 hours
B) 24 hours
C) 48 to 60 hours
D) 120 hours
Correct Answer: C
Clinical steady-state is reliably achieved at 4 to 5 half-lives. With a 12-hour half-life, 4 half-
lives equals 48 hours and 5 half-lives equals 60 hours. Do not confuse drug onset with
