COMPLETE ACCURATE TEST ACTUAL QUESTIONS AND CORRECT
VERIFIED SOLUTIONS WITH RATIONALES
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 dosin g (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 in teractions 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.
Abruptly stopping use in chronic users leads to severe symptoms, which motivates
continued use to prevent withdrawal. The 2016 CDC guidelines for prescribing opioids
recommends calculating the total daily dose of opioids to help identify patients who
might benefit from the reduction or tapering of opioids, given the risk of overdose
State Prescription Drug - //correct answer//Clinicians should review the patient's history
of controlled substance prescriptions using state prescription drug monitoring program
(PDMP) data to determine whether the patient is receiving opioid dosages or dangerous
combinations that put him or her at high risk for overdose. Clinicians should review
PDMP data when starting opioid therapy for chronic pain and periodically during opioid
therapy for chronic pain, ranging from every prescription to every 3 months.
Monitoring Programs - //correct answer//safeguards to address the opioid public health
crisis include prescription drug monitoring programs (PDMPs). These electronic
databases enable providers to access in formation regarding a patient's prescription
history of controlled substances. Nearly all states have implemented PDMPs, and some
states require providers to check the PDMP before prescribing controlled substances.
