1: What does APRN prescriptive authority encompass beyond medications?
Correct Answer: Therapeutic devices and services including DME (wheelchairs, oxygen, hospital
beds), handicap placards, PT, OT, home health services
1. Prescriptive authority is defined by state practice laws and includes ordering durable medical
equipment and services.
2. Requires adherence to ethical guidelines and being well-informed about mechanisms, efficacy,
safety, and patient circumstances.
3. Appropriate selection, dosing, and duration are key to maximizing outcomes and minimizing
adverse effects.
2: What are the benefits of full practice authority for nurse practitioners?
Correct Answer: NPs have autonomy to evaluate, diagnose, order/interpret tests, initiate/manage
treatments, and prescribe medications including controlled substances without physician oversight
1. Full practice authority increases access to care, especially in rural/underserved areas.
2. Reduces healthcare costs and improves patient outcomes through timely care.
3. Supported by evidence showing NP outcomes equivalent or superior to physician-only care.
3: What documentation is required for prudent prescribing practices?
Correct Answer: Documentation of provider-patient relationship, thorough H&P, discussions of risk
factors/side effects/therapy options, drug monitoring/titration plan, consultations, and avoidance of
prescribing for self/family/friends
1. Thorough documentation maintains patient safety and reduces liability.
2. Rational drug selection requires clinical reasoning and monitoring.
3. Considerations include cost, guidelines, availability, interactions, side effects, allergies,
hepatic/renal function, monitoring needs, and special populations.
, 4: What is the Beers Criteria?
Correct Answer: Identifies drugs with high likelihood of causing adverse effects in older adults (≥65
years); generally should be avoided unless benefits significantly outweigh risks
1. Developed by American Geriatrics Society.
2. Lists potentially inappropriate medications regardless of condition.
3. Helps reduce polypharmacy and adverse drug events in elderly.
5: Define pharmacodynamics.
Correct Answer: The study of the biochemical and physiologic effects of drugs on the body and the
molecular mechanisms by which those effects are produced
1. Pharmacodynamics describes "what the drug does to the body."
2. Includes receptor binding, signal transduction, and dose-response relationships.
3. Determines drug efficacy and potency.
6: Define pharmacokinetics.
Correct Answer: The study of drug movement throughout the body (absorption, distribution,
metabolism, excretion – ADME)
1. Pharmacokinetics describes "what the body does to the drug."
2. Predicts drug concentration over time.
3. Influences dosing, route, and frequency.
7: Define pharmacogenomics.
Correct Answer: The study of how genes affect a person's response to drugs; combines genomics and
pharmacology to provide individualized, targeted, safe drug therapies
1. Genetic variations influence drug metabolism, efficacy, and toxicity.
2. CYP450 polymorphisms (poor, intermediate, extensive, ultrarapid metabolizers) guide dosing.
3. Helps avoid adverse drug reactions and therapeutic failures.
8: What do CYP450 inducers do, and give examples?
Correct Answer: Inducers elevate CYP450 enzyme activity (increase synthesis), increasing medication
metabolism, decreasing parent drug concentration. Examples: Carbamazepine, Rifampin, Alcohol,
Phenytoin, Griseofulvin, Phenobarbital, Sulfonylureas
1. Induction leads to faster drug clearance → potential therapeutic failure.
2. May require increased doses when inducer is added.
3. Mnemonic: "CRAP GPS" – Carbamazepine, Rifampin, Alcohol, Phenytoin, Griseofulvin,
Phenobarbital, Sulfonylureas.
