NR565 / NR 565 MIDTERM EXAM STUDY GUIDE | ADVANCED PHARMACOLOGY PRACTICE
QUESTIONS & ANSWERS 2026/2027
APRN prescribing role - correct answer ✔✔Prescriptive authority for nurse practitioners also
regulates prescribing rights beyond medications and controlled substances. These rights include
therapeutic devices and services and are outlined in state practice laws and regulations and
include Durable Medical Equipment (DME) such as wheelchairs, power scooters, hospital beds,
portable oxygen equipment, handicap placards, etc. and medical services such as Physical
Therapy (PT), Occupational Therapy (OT), home health services, etc. Prescriptive authority
encompasses more than writing a prescription correctly. It requires adherence to ethical
guidelines to ensure that patients are safeguarded from harm. Ethical prescribing starts with
being well-informed about medications. Mechanism of action, efficacy, and safety are important
considerations, as are a patient's distinct needs and circumstances, including the number of
medications prescribed (Mitchell & Oliphant, 2016). Most patients receiving a prescription are
taking other medications, whether prescription or over-the-counter. Appropriate selection,
dosing, and duration of pharmaceutical agents are key to maximizing outcomes and minimizing
adverse effects
benefits of full practice authority - correct answer ✔✔Nurse practitioners have the autonomy to
evaluate patients, diagnose, order and interpret tests, initiate and manage treatments and
prescribe medications, including controlled substances without physician oversight
promoting positive outcomes through prudent prescribing practices - correct answer
✔✔Administering medications and prescribing medications are two distinct processes.
Prescription writing requires prudent and deliberate decision-making processes to maintain
patient safety and reduce liability, including:
*documentation of a provider-patient relationship for the recipient of the prescribed
medications
*documentation of a thorough history and physical examination for the recipient
,*documentation of discussions regarding risk factors, side effects, or therapy options
*documentation of drug monitoring or titration plan, if applicable
*documentation of consultations, if any
avoidance of prescribing medications for self, family, or friends
Rational drug selection requires a logical approach that includes the formulation of a diagnosis
based on clinical reasoning and the selection and monitoring of the most appropriate
pharmacological treatment
Considerations include: Cost, guidelines, availability, interactions, side effects, allergies,
hepatic/renal functions, need for monitoring, & special populations
Beer's Criteria - correct answer ✔✔identifies drugs with a high likelihood of causing adverse
effects in older adults. Accordingly, drugs on this list should generally be avoided in adults older
than 65 years except when the benefits are significantly greater than the risks.
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
Pharmacokinetics - correct answer ✔✔the study of drug movement throughout the body
Pharmacogenomics - correct answer ✔✔the study of how genes affect a person's response to
drugs. The purpose of this is to combine the sciences of genomics and pharmacology to provide
individualized, targeted, safe drug therapies to patients
CYP450 inducers - correct answer ✔✔Inducers are xenobiotics (medications and environmental
agents) that elevate CYP450 enzyme activity by increasing enzyme synthesis. This action leads
,to additional sites available for biotransformation. The increased number of sites enhances
medication metabolism, decreasing the concentration of the "parent drug" while increasing
metabolite production.
Inducers = Increase medication metabolism
(Carbamazepine, Rifampin, Alcohol, Phenytoin, Griseofulvin, Phenobarbital, Sulfonylureas)
CYP450 inhibitors - correct answer ✔✔Inhibitors are medications that inhibit the metabolic
activity of one or more of the CYP450 enzymes. Medications that inhibit an enzyme potentially
slows that enzyme's activity or blocks the activity required for the metabolism of other
medications, thereby increasing the levels of medications dependent on that particular enzyme
for biotransformation. Inhibitors = decrease medication metabolism (Valproate, Isoniazid,
Sulfonamides, Amiodarone, Chloramphenicol, Ketoconazole, Grapefruit Juice, Quinidine)
cultural influences in prescribing - correct answer ✔✔The greatest concern surrounding race-
based therapy has to do with genetic variability. We know there is great diversity within and
among racial groups; therefore, a "one fits all" approach based on race is unwise. Still, we can
use known associations to guide choices. For example, differences in metabolism between
people with East Asian and European heritage are common. The provider can use this
knowledge to guide initial dosing (with adjustment, as indicated based on response) if genetic
testing is not feasible or warranted
Polypharmacy: Definition, challenges, and outcomes - correct answer ✔✔treatment with
multiple drugs
greatly increases the risk for interactions. Some of these interactions are negligible, but some
can have life-threatening consequences. It is of crucial importance to ask the patient about all
current drugs, including over-the-counter (OTC) medications and other herbal preparations.
Many patients do not consider OTC or alternative pharmaceuticals as "medications" and may
not mention them unless you ask specifically.
, Acute Pain Management - correct answer ✔✔
Chronic Pain Management - correct answer ✔✔
Opioid Management - correct answer ✔✔
Regulations of Controlled Substances - correct answer ✔✔The U.S. Department of Justice Drug
Enforcement Agency (DEA) coordinates with local, state, and federal agents to reduce illicit drug
use. The DEA enacted the Controlled Substances Act (CSA) in 1970 to regulate drugs and other
substances based on their potential for abuse and dependency. Five schedules of controlled
substances were created that are updated annually. Classes of scheduled substances include
narcotics, depressants, stimulants, hallucinogens, and anabolic steroids. The DEA issues eligible
providers with a registration number to write prescriptions for controlled substances.
Characteristics of a valid DEA number include:
-The first letter identifies the type of provider: A=before 1985; B=after 1985; F=after 2007;
M=nurse practitioner or physician assistant
-The 2nd letter the 1st letter of the provider's last name at the time of initial registration
Example: Tammy Greene applies for and receives a DEA number of MG2705208
M=nurse practitioner and G=Greene
Opioid Epidemic & Responsible Prescribing - correct answer ✔✔
Opioid Use Disorder - correct answer ✔✔a pattern of use that leads to significant impairment
or distress. Typically, this disorder is marked by unsuccessful efforts to reduce or control use
resulting in the inability to fulfill work, school, or home responsibilities. Opioid use disorder is
different from drug tolerance and physical dependence, which may also exist. Opioid use
creates high levels of positive reinforcement, increasing the likelihood of continued use. It is
often a chronic lifelong disorder, leading to serious consequences such as disability and death.
Although it is similar to other substance use disorders, it has distinct features that have fueled
the current opioid epidemic. Opioids can lead to physical dependence in only 4-8 weeks.
