, 1 Prescriptive Authority and Rational Drug Selec-
tion
1. How would the APRN’s prescriptive authority be described if they work
in a urology clinic under a physician who does not restrict medication
types, and state law does not require physician supervision?
Answer: Independent.
Rationale: The APRN has independent prescriptive authority because they
do not need to work under physician supervision. Full authority means
prescribing without limits, and limited authority means restrictions on drug
types.
2. Which factor increases the need for APRNs to have full prescriptive
authority?
Answer: More patients will have access to health care.
Rationale: The Affordable Care Act increased health care coverage, lead-
ing to more patients needing care, and APRNs can help meet this need by
prescribing medications.
3. Which factors could be attributed to limited prescriptive authority for
APRNs? Select all that apply.
Answer: Inaccessibility of patient care, Higher health care costs.
Rationale: Limiting authority can create barriers to affordable and acces-
sible care and increase costs. It does not directly affect health literacy or
improve collaborative care.
4. Which aspects support the APRN’s provision for full prescriptive au-
thority? Select all that apply.
Answer: Clinical education includes prescription of medications and dis-
ease processes, National examinations provide validation of the APRN’s
ability to provide safe care, Licensure ensures compliance with health care
and safety standards.
Rationale: APRNs are trained to prescribe independently, exams ensure
safe care, and licensure promotes public health. Limited authority can de-
crease affordability of care.
5. A family nurse practitioner moves from Maine to Virginia. Which as-
pect of practice may change?
Answer: The APRN will have less prescriptive authority in the new posi-
tion.
Rationale: Virginia has limited prescriptive authority, while Maine gives
full authority. Federal regulations do not control this.
6. How can collaboration with a pharmacist improve positive outcomes
for patients? Select all that apply.
Answer: Pharmacists have additional information on drug interactions,
The pharmacist can suggest adequate medication dosing, Pharmacists have
firsthand knowledge of the facility formulary.
Rationale: Pharmacists help with drug interactions, dosing, and formulary
