Chamberlain QUESTIONS WITH WELL VEERIFIED ANSWERS
APRN prescribing role - 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 - 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 -
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 - 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 - 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 - answer☑️✔️...the study of drug movement throughout the body
Pharmacogenomics - 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 - 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 - 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 - 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 - 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 - answer☑️✔️...
Chronic Pain Management - answer☑️✔️...
Opioid Management - answer☑️✔️...
Regulations of Controlled Substances - 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 - answer☑️✔️...
Opioid Use Disorder - 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
