1. A nurse working in radiology administers iodine to a patient who is having a
f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


computedtomography (CT) scan. The nurse working on the oncology unit
f 6 f6 f6 f6 f6 f6 f6 f6 f6 f6


administers chemotherapy to patients who have cancer. At the Public Health
f6 f 6 f6 f6 f6 f6 f6 f6 f6 f6 f6


Department, a nurse administers a measles-mumps-rubella (MMR) vaccine to
f6 f6 f6 f 6 f6 f6 f6 f6 f6


a 14-month-old child as a routine immunization. Which branch of
f6 f6 f6 f6 f6 f 6 f6 f6 f6 f6


pharmacology best describes the actions of all three nurses?
f6 f6 f6 f6 f6 f6 f6 f 6 f6




A) Pharmacoeconomics
B) Pharmacotherapeutics
C) Pharmacodynamics
D) Pharmacokinetics
ANSWER: B
Feedback:
Pharmacology is the study of the biologic effects of chemicals. Nurses are
f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


involved with clinical pharmacology or pharmacotherapeutics, which is a
f6 f 6 f6 f6 f6 f6 f6 f6 f6


branch of pharmacology that deals with the uses of drugs to treat, prevent,
f6 f6 f 6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


and diagnose disease. The radiology nurse is administering a drug to help
f6 f6 f6 f 6 f6 f6 f6 f6 f6 f6 f6 f6


diagnose a disease. The oncology nurse is administering a drug to help treat
f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


a disease. Pharmacoeconomics includes any costs involved in drug therapy.
f6 f6 f6 f6 f6 f 6 f6 f6 f6 f6


Pharmacodynamics involves how a drug affects the body and
f6 f6 f6 f6 f6 f6 f6 f 6 f6


pharmacokinetics is how the body acts on the body.

2. A physician has ordered intramuscular (IM) injections of morphine, a
f6 f6 f6 f6 f6 f6 f6 f6 f6


narcotic, every 4 hours as needed for pain in a motor vehicle
f 6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


accident victim. The nurse is aware this drug has a high abuse
f6 f 6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


potential. Under what category would morphine be classified?
f6 f6 f6 f 6 f6 f6 f6 f6




A) Schedule I f6




B) Schedule II f6




C) Schedule III f6




D) Schedule IV f6




ANSWER: B

, Feedback:
Narcotics with a high abuse potential are classified as Schedule II drugs
f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


because of severe dependence liability. Schedule I drugs have high
f 6 f6 f6 f6 f6 f6 f6 f6 f6 f6


abuse potential and no accepted medical use. Schedule III drugs have
f6 f 6 f6 f6 f6 f6 f6 f6 f6 f6 f6


a lesser abuse potential than II and an accepted medical use.
f6 f6 f 6 f6 f6 f6 f6 f6 f6 f6 f6


Schedule IV drugs have low abuse potential and limited dependence
f6 f6 f6 f6 f 6 f6 f6 f6 f6 f6


liability.

3. When involved in phase III drug evaluation studies, what
f6 f6 f6 f6 f6 f6 f6 f6


responsibilities would the nurse have?
f6 f 6 f6 f6 f6




A) Working with animals who are given experimental drugs
f6 f6 f6 f6 f6 f6 f6




B) Choosing appropriate patients to be involved in the drug study
f6 f6 f6 f6 f6 f6 f6 f6 f6




C) Monitoring and observing patients closely for adverse effects
f6 f6 f6 f6 f6 f6 f6




D) Conducting research to determine effectiveness of the drug
f6 f6 f6 f6 f6 f6 f6




ANSWER: C
Feedback:
Phase III studies involve use of a drug in a vast clinical population in
f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


which patients are asked to record any symptoms they experience
f6 f 6 f6 f6 f6 f6 f6 f6 f6 f6


while taking the drugs. Nurses may be responsible for helping
f6 f6 f6 f 6 f6 f6 f6 f6 f6 f6


collect and analyze the information to be shared with the Food and
f6 f6 f6 f6 f 6 f6 f6 f6 f6 f6 f6 f6


Drug Administration (FDA) but would not conduct research
f6 f6 f6 f6 f 6 f6 f6 f6


independently because nurses do not prescribe medications. Use of
f6 f6 f6 f6 f6 f6 f 6 f6 f6


animals in drug testing is done in the preclinical trials. Select
f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f 6


patients who are involved in phase II studies to participate in studies
f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


f 6where the participants have the disease the drug is intended to
f6 f6 f6 f6 f6 f6 f6 f6 f6 f6


treat. These patients are monitored closely for drug action and
f6 f6 f 6 f6 f6 f6 f6 f6 f6 f6


adverse effects. Phase I studies involve healthy human volunteers
f6 f6 f6 f6 f 6 f6 f6 f6 f6


who are usually paid for their participation. Nurses may observe
f6 f6 f6 f6 f6 f6 f 6 f6 f6 f6


for adverse effects and toxicity.

4. What concept is considered when generic drugs are substituted
f6 f6 f6 f6 f6 f6 f6 f6


for brand name drugs?
f6 f6 f 6 f6

B) Critical concentration f6




C) Distribution
D) Half-life
