Question 1: 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).
Correct Answer: CYP450 inhibitors
Question 2: 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).
Correct Answer: CYP450 inducers
Question 3: 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.
Correct Answer: Pharmacogenomics
Question 4: The study of drug movement throughout the body.
Correct Answer: Pharmacokinetics
Question 5: The study of the biochemical and physiologic effects of drugs on the body and
the molecular mechanisms by which those effects are produced.
Correct Answer: Pharmacodynamics
, 2
Question 6: 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.
Correct Answer: Beer's Criteria
Question 7: 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.
Correct Answer: Rational drug selection
Question 8: 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; documentation of a thorough history and physical examination;
documentation of discussions regarding risk factors, side effects, or therapy options;
documentation of drug monitoring or titration plan; documentation of consultations; and
avoidance of prescribing medications for self, family, or friends.
Correct Answer: Promoting positive outcomes through prudent prescribing practices
Question 9: 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.
Correct Answer: Benefits of full practice authority
Question 10: 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.
Correct Answer: APRN prescribing role
Question 11: 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
, 3
"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.
Correct Answer: Cultural influences in prescribing
Question 12: 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.
Correct Answer: Polypharmacy: Definition, challenges, and outcomes
Question 13: 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
(e.g., M=nurse practitioner or physician assistant); The 2nd letter is the 1st letter of the
provider's last name at the time of initial registration.
Correct Answer: Regulations of Controlled SubstancesThis is ready to be copied and
pasted directly into your Word document!
Question 14: Substances, or chemicals are defined as drugs with no currently accepted
medical use and a high potential for abuse. Examples: heroin, LSD, marijuana,
methylenedioxymethamphetamine (ecstasy), methaqualone, and peyote.
Correct Answer: Schedule I Drugs
Question 15: Is the length of time that particular drug is effective. Duration of action is a
function of several parameters including plasma half-life, the time to equilibrate between
plasma and target compartments, and the off rate of the drug from its biological target.
Correct Answer: The duration of action of a drug
, 4
Question 16: A drug that attenuates the effects of agonists or inverse agonists, producing a
functional reduction in signal transduction. Affects only ligand-dependent receptor
activation and displays no intrinsic activity itself. Also known as a neutral antagonist.
Correct Answer: Silent Antagonist
Question 17: A drug that binds to and activates a receptor. Can be full, partial or inverse. A
full agonist has high efficacy, producing a full response while occupying a relatively low
proportion of receptors. A partial agonist has lower efficacy than a full agonist. It produces
sub-maximal activation even when occupying the total receptor population, therefore
cannot produce the maximal response, irrespective of the concentration applied. An
inverse agonist produces an effect opposite to that of an agonist, yet it binds to the same
receptor binding-site as an agonist.
Correct Answer: Agonist
Question 18: A drug that attenuates the effect of an agonist. Can be competitive or non-
competitive, each of which can be reversible or irreversible. A competitive antagonist binds
to the same site as the agonist but does not activate it, thus blocks the agonist's action. A
non-competitive antagonist binds to an allosteric (non-agonist) site on the receptor to
prevent activation of the receptor. A reversible antagonist binds non-covalently to the
receptor, therefore can be "washed out". An irreversible antagonist binds covalently to the
receptor and cannot be displaced by either competing ligands or washing.
Correct Answer: Antagonist
Question 19: Is the amount of a medication between the amount that gives an effect
(effective dose) and the amount that gives more adverse effects than desired effects. For
instance, medication with a small pharmaceutical window must be administered with care
and control, e.g. by frequently measuring blood concentration of the drug, since it easily
loses effects or gives adverse effects.
Correct Answer: The therapeutic window
Question 20: Each drug preparation regulated under the CSA has been assigned to one of
five categories: schedule I, II, III, IV, or V. Drugs in schedule I have a high potential for abuse
and no approved medical use in the United States. In contrast, drugs in schedules II
through V all have approved applications. Assignment to schedules II through V is based on
abuse potential and potential for causing physical or psychological dependence. Of the
drugs that have medical applications, those in schedule II have the highest potential for
abuse and dependence. Drugs in the remaining schedules have decreasing abuse and
dependence liabilities.
