2023 TEST BANK FOCUS ON NURSING
PHARMACOLOGY 9TH EDITION BY AMY KARCH |
COMPLETE GUIDE 2023.

A nurse working in radiology administers iodine to a patient who is having a computed

tomography (CT) scan. The nurse working on the oncology unit administers

chemotherapy to patients who have cancer. At the Public Health Department, a nurse

administers a measles-mumps-rubella (MMR) vaccine to a 14-month-old child as a

routine immunization. Which branch of pharmacology best describes the actions of all
1.
three nurses?


A)
Pharmacoeconomics


B)
Pharmacotherapeutics


C)
Pharmacodynamics


D)
Pharmacokinetics


Ans: B



Feedback:


Pharmacology is the study of the biologic effects of chemicals. Nurses are involved with

clinical pharmacology or pharmacotherapeutics, which is a branch of pharmacology that

deals with the uses of drugs to treat, prevent, and diagnose disease. The radiology nurse is

administering a drug to help diagnose a disease. The oncology nurse is administering a

, lOMoARcPSD|821 361 6




drug to help treat a disease. Pharmacoeconomics includes any costs involved in drug

therapy. Pharmacodynamics involves how a drug affects the body and pharmacokinetics

is how the body acts on the body.
A physician has ordered intramuscular (IM) injections of morphine, a narcotic, every 4

hours as needed for pain in a motor vehicle accident victim. The nurse is aware this drug
2.
has a high abuse potential. Under what category would morphine be classified?


A)
Schedule I


B)
Schedule II


C)
Schedule III


D)
Schedule IV


Ans: B



Feedback:


Narcotics with a high abuse potential are classified as Schedule II drugs because of severe

dependence liability. Schedule I drugs have high abuse potential and no accepted medical

use. Schedule III drugs have a lesser abuse potential than II and an accepted medical use.

Schedule IV drugs have low abuse potential and limited dependence liability.

When involved in phase III drug evaluation studies, what responsibilities would the nurse
3.
have?

, lOMoARcPSD|821 361 6




A)
Working with animals who are given experimental drugs


B)
Choosing appropriate patients to be involved in the drug study


C)
Monitoring and observing patients closely for adverse effects


D)
Conducting research to determine effectiveness of the drug


Ans: C



Feedback:


Phase III studies involve use of a drug in a vast clinical population in which patients are

asked to record any symptoms they experience while taking the drugs. Nurses may be

responsible for helping collect and analyze the information to be shared with the Food

and Drug Administration (FDA) but would not conduct research independently because

nurses do not prescribe medications. Use of animals in drug testing is done in the

preclinical trials. Select patients who are involved in phase II studies to participate in

studies where the participants have the disease the drug is intended to treat. These patients

are monitored closely for drug action and adverse effects. Phase I studies involve healthy

human volunteers who are usually paid for their participation. Nurses may observe for

adverse effects and toxicity.


4.
What concept is considered when generic drugs are substituted for brand name drugs?

, lOMoARcPSD|821 361 6




A)
Bioavailability


B)
Critical concentration


C)
Distribution


D)
Half-life


Ans: A



Feedback:


Bioavailability is the portion of a dose of a drug that reaches the systemic circulation and

is available to act on body cells. Binders used in a generic drug may not be the same as

those used in the brand name drug. Therefore, the way the body breaks down and uses the

drug may differ, which may eliminate a generic drug substitution. Critical concentration is

the amount of a drug that is needed to cause a therapeutic effect and should not differ

between generic and brand name medications. Distribution is the phase of

pharmacokinetics, which involves the movement of a drug to the body’s tissues and is the

same in generic and brand name drugs. A drug’s half-life is the time it takes for the

amount of drug to decrease to half the peak level, which should not change when

substituting a generic medication.

A nurse is assessing the patient’s home medication use. After listening to the patient list

current medications, the nurse asks what priority question?
