Karch's Focus On Nursing Pharmacology,
9th Edition Test Bank By Rebecca Tucker
,Chapter 01 - Introduction To Drugs
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 Three
Nurses?
Pharmacoeconomics
Pharmacotherapeutics
Pharmacodynamics
Pharmacokinetics
Answer: 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 OfDrugs To Treat, Prevent, And Diagnose Disease. The Radiology Nurse Is
Administering A Drug To Help Diagnose A Disease. The Oncology Nurse Is Administering A Drug
To Help Treat A Disease.
Pharmacoeconomics Includes Any Costs Involved In Drug Therapy. Pharmacodynamics Involves
How ADrug 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 ForPain In A Motor Vehicle Accident Victim. The Nurse Is Aware This Drug Has A High
Abuse Potential.
Under What Category Would Morphine Be Classified?
Schedule I
Schedule II
Schedule III
Schedule IV
Answer: 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 AbusePotential And Limited Dependence Liability.
When Involved In Phase III Drug Evaluation Studies, What Responsibilities Would The Nurse
Have?Working With Animals Who Are Given Experimental Drugs
Choosing Appropriate Patients To Be Involved In The Drug Study
Monitoring And Observing Patients Closely For Adverse Effects
Conducting Research To Determine Effectiveness Of The Drug
Answer: C
Feedback:
Phase III Studies Involve Use Of A Drug In A Vast Clinical Population In Which Patients Are Asked
To RecordAny 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 ParticipateIn 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 VolunteersWho Are Usually Paid For Their
Participation. Nurses May Observe For Adverse Effects And Toxicity.
What Concept Is Considered When Generic Drugs Are Substituted For Brand Name
Drugs?Bioavailability
Critical
Concentration
Distribution
Half-Life
Answer: 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 ToDecrease 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?
Do You Take Any Generic Medications?
Are Any Of These Medications Orphan Drugs?
Are These Medications Safe To Take During
Pregnancy?Do You Take Any Over-The-Counter
Medications?
Answer: D
Feedback:
It Is Important For The Nurse To Specifically Question Use Of Over-The-Counter Medications
Because Patients May Not Consider Them Important. The Patient Is Unlikely To Know The Meaning
Of Orphan DrugsUnless They Too Are Health Care Providers. Safety During Pregnancy, Use Of A
Generic Medication, Or Classification Of Orphan Drugs Are Things The Patient Would Be Unable To
Answer But Could Be Found In Reference Books If The Nurse Wishes To Research Them.
After Completing A Course On Pharmacology For Nurses, What Will The Nurse
Know?Everything Necessary For Safe And Effective Medication Administration
Current Pharmacologic Therapy; The Nurse Will Not Require Ongoing Education For 5
Years. General Drug Information; The Nurse Can Consult A Drug Guide For Specific
Drug Information.The Drug Actions That Are Associated With Each Classification Of
Medication Answer: C
Feedback:
After Completing A Pharmacology Course Nurses Will Have General Drug Information Needed For
Safe AndEffective Medication Administration But Will Need To Consult A Drug Guide For Specific
Drug Information Before Administering Any Medication. Pharmacology Is Constantly Changing, With
