Exam 1 Pharmacology for
Nurses (CHAPTER 1-5)
What is the difference between therapeutic and pharmacologic classifications?
Identify the following classifications as therapeutic or pharmacologic:
betaadrenergic blocker, oral contraceptive, laxative, folic acid antagonist, and
antianginal drug. - ANS-The therapeutic classification is a method of organizing
drugs based on their therapeutic usefulness in treating particular diseases. The
pharmacologic classification refers to how a drug works at the molecular, tissue,
and body system levels. A beta-adrenergic blocker is a pharmacologic class; an
oral contraceptive is a therapeutic class; laxative is a therapeutic class; folic acid
antagonist is a pharmacologic class; antianginal is a therapeutic class.
Chapter 1
How does the FDA ensure the safety and effectiveness of drugs? What types of
drugs does the FDA regulate or control? - ANS-The FDA, through its Center for
Drug Evaluation and Research (CDER), exercises control over whether prescription
drugs and OTC drugs may be used for therapy. The mission of the CDER is to
facilitate the availability of safe, effective drugs; keep unsafe or ineffective drugs
off the market; improve the health of Americans; and provide clear, easily
understandable drug information for safe and effective use. The FDA's Center for
Biologics Evaluation and Research (CBER) regulates the use of biologics including
serums, vaccines, and blood products.
Chapter 2
Why are certain drugs placed in schedules? What does the nurse need to know
when a scheduled drug is ordered? - ANS-Schedules refer to the potential for
abuse. These schedules help the nurse identify the potential for abuse and
, require the nurse to maintain complete records for all quantities prescribed. The
higher the abuse potential, the more restrictions are placed on the prescriber and
the filling of refills. When educating the patient about a prescription, the nurse
should also include this information on any prescription or refills as part of the
education.
Chapter 2
A nurse is preparing to give a patient a medication and notes that a drug to be
given is marked as a Schedule III drug. What does this information tell the nurse
about this medication? - ANS-This Schedule III drug is a controlled substance
restricted by the Controlled Substance Act of 1970 and regulated by the DEA. A
Schedule III drug has a moderate abuse potential, moderate potential for physical
dependency, and high potential for psychologic dependency.
Chapter 2
What is the role of the nurse in medication administration? (Select all that apply.)
1. Ensure that medications are administered and delivered in a safe manner.
2. Be certain that healthcare provider orders are accurate.
3. Inform the patient that prescribed medications need to be taken only if the
patient agrees with the treatment plan.
4. Ensure that the patient understands the use and administration technique for
all prescribed medications.
5. Prevent adverse drug reactions by properly administering all medications. -
ANS-1. Ensure that medications are administered and delivered in a safe manner.
4. Ensure that the patient understands the use and administration technique for
all prescribed medications.
Chapter 3
Before administering drugs by the enteral route, the nurse should evaluate which
of the following?
1. Ability of the patient to lie supine
2. Compatibility of the drug with intravenous fluid
3. Ability of the patient to swallow
4. Patency of the injection port - ANS-3. Ability of the patient to swallow
