UNITEK HAYWARD Pharmacology | Quiz 1 | Chapters1, 2, 3 | Latest Update Already Passed
Which description best defines a medication?
A) Chemical substance that requires a prescription by a health professional
B) Drug used for a therapeutic effect to treat or prevent an illness
C) Pharmacologic preparation used to reverse disease
D) Plant, animal, or mineral substance that prevents disease - ANSWER B) Drug
used for a therapeutic effect to treat or prevent an illness
Medications are drugs used for their therapeutic effects. A therapeutic effect can be
the prevention or treatment of disease. All medications do not require a prescription.
Specifying a certain action is not the best definition of a medication because it is
incomplete.
What is the trade name of a drug?
A) The proprietary name of the drug given by a manufacturer.
B) The chemical name of the drug given by its developer.
C) The name given to the drug by the U.S. Food and Drug Administration (FDA).
D) The name under which the drug is listed in the U.S. Pharmacopeia. - ANSWER
A) The proprietary name of the drug given by a manufacturer.
The trade or brand name is the proprietary name given to the drug by its
manufacturer. The same drug produced by different companies has one generic
name but may have many trade names. The trade name is trademark protected and
can be used only by its manufacturer. The drug may be listed under more than one
name in the Pharmacopeia. The book is used to provide standards for identity,
quality, strength, and purity of substances used in healthcare practice. The trade
name is not given to a drug by the FDA. The chemical name is the exact chemical
constitution of the drug and the exact placing of its atoms or molecular groupings.
What is the MedWatch form used for?
A) Tracking numbers of prescriptions written for a specific drug
B) Assessing the acceptability of the drug to individual patients
C) Determining the therapeutic effectiveness of the drug
D) Identifying adverse effects of a drug in the general population - ANSWER D)
Identifying adverse effects of a drug in the general population
Healthcare practitioners make a significant contribution to the knowledge of drug
safety by reporting adverse effects to the FDA using the MedWatch program for the
voluntary reporting of adverse events and product problems. This method of
identifying adverse effects of a drug in the general population is part of the
postmarketing surveillance phase of drug development. More than 200,000
MedWatch forms are filed with the FDA annually. MedWatch is not designed to track
the numbers of prescriptions written for a specific drug; is not a program involved in
determining the therapeutic effectiveness of a drug; and is not involved in assessing
the acceptability of a drug to individual patients.
Which statement about drug names is correct?
,A) Drugs are listed by their chemical names in the U.S. Pharmacopeia.
B) A drug may have multiple proprietary names.
C) The generic name is a trademarked name.
D) The official name must be used on all prescriptions. - ANSWER B) A drug may
have multiple proprietary names.
The proprietary name of a drug is a trade or brand name and is followed by the
symbol ®. Each manufacturer of a drug can register a proprietary name that can be
used only by that company. Thus a drug produced by more than one manufacturer
can have multiple proprietary names but only one generic name. Drugs are listed by
their official names in the U.S. Pharmacopeia. Generic names are not trademarked.
Prescriptions can be written using generic or trade names.
How do Schedule II drugs differ from Schedule V drugs?
A) Schedule V drugs have greater risk for toxicity.
B) Schedule II drugs have less potential for abuse.
C) Schedule V drugs lack accepted safety measures for use.
D) Schedule II drugs are more likely to cause dependence. - ANSWER D)
Schedule II drugs are more likely to cause dependence.
Schedule II drugs have a high potential for abuse that may lead to severe
psychological or physical dependence. Schedule II drugs have more, not less,
potential for abuse than Schedule V drugs. Schedule II and Schedule V drugs have
accepted guidelines for safe use. Drugs in both schedules are not differentiated
based on toxicity. There may be drugs in each schedule that have high or low
toxicity.
Which legislation was written to require companies to determine the safety of
medications before marketing?
A) The Federal Food, Drug, and Cosmetic Act of 1938
B) Durham Humphrey Amendment of 1952
C) The Kefauver Harris Drug Amendment of 1962
D) Controlled Substance Act of 1970 - ANSWER A) The Federal Food, Drug, and
Cosmetic Act of 1938
The Federal Food, Drug, and Cosmetic Act of 1938 (passed on June 25, 1938, and
amended in 1952 and 1962) requires the FDA to determine the safety of drugs
before marketing and to ensure that certain labeling specifications and standards in
advertising are met in the marketing of products. Manufacturers are required to
submit new drug applications to the FDA for review of safety studies before products
can be released. The Durham Humphrey Amendment of 1952 was passed to tighten
control over prescription drugs by restricting the refilling of prescriptions. The
Kefauver Harris Drug Amendment of 1962 was brought about by the thalidomide
tragedy. The amendment provides greater control and surveillance of the distribution
and clinical testing of investigational drugs, and requires that a product be proven
safe and effective before release for sale. The Controlled Substance Act of 1970 was
passed by Congress to improve the administration and regulation of manufacturing,
distributing, and dispensing of drugs that have been found necessary to be
controlled.
Which legislation was enacted to stimulate development and availability of drugs to
treat rare diseases?
A) The Orphan Drug Act
, B) The Fast Tracking rules
C) The Controlled Drugs and Substance Act of 1997
D) The Food and Drug Act of 1979 - ANSWER A) The Orphan Drug Act
The medicines that are developed for rare conditions are known as orphan drugs,
because the manufacturers have been unable to recover the costs of the research
due to the very limited use of the final product. Because no companies were willing
to "adopt" the disease to complete extensive research to develop products for
treatment, the diseases became known as health orphans. In 1983, Congress
passed the Orphan Drug Act to stimulate the development and market availability of
products that are used for the treatment of rare diseases. The Orphan Drug Act
provides research grants, protocol development assistance by the FDA, special tax
credits for the cost of clinical trials, and 7 years of exclusive marketing rights after the
product has been approved. The Food and Drug Act of 1979 empowered Health
Canada to protect the public from foreseeable risks relating to the manufacture and
sale of drugs. The Fast Tracking rules allow investigational drugs to receive highest
priority for review with the FDA. The Controlled Drugs and Substance Act of 1997
established the requirements for control and sale of narcotics and substances of
abuse in Canada.
Which stage of new drug development involves giving the medication to large
numbers of individuals with the disorder that the medication intends to treat?
A) Developmental stage—Phase 2
B) Postmarketing surveillance stage
C) Developmental stage—Phase 1
D) Developmental stage—Phase 3 - ANSWER D) Developmental stage—Phase 3
If phase 1 trials are successful, the drug is moved to phase 2, which involves a
smaller population of patients who have the condition that the drug is designed to
treat. Studies at various dosages are conducted to determine the success rate and
safety of a drug for its intended use. If successful, the drug is advanced to phase 3
trials, in which larger patient populations are used to ensure the statistical
significance of the results. Studies in this phase also provide additional information
on proper dosing and safety. Phase 1 studies are done to determine an experimental
drug's pharmacologic properties, safe dosage range, potential for toxicity at a certain
dosage, and safe routes of administration. The study population consists of either
normal volunteers or the intended treatment population, such as those patients who
have failed standard treatments of certain cancers or dysrhythmias. Phase 2 studies
usually require 20 to 100 subjects, who are treated for 4 to 6 weeks. Studies in this
phase are done to determine the success rate of a drug for its intended use. After
the manufacturer decides to market the medication, there is ongoing review of
adverse effects of the new drug, as well as periodic inspections of the manufacturing
facilities and products.
Which governmental body was organized to gather intelligence, train, conduct
research in the area of dangerous drugs and drug abuse, and enforce the Controlled
Substances Act?
A) Central Intelligence Agency (CIA)
B) FDA
C) Drug Enforcement Administration (DEA)
D) Federal Bureau of Investigation (FBI) - ANSWER C) Drug Enforcement
Administration (DEA)
