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



having a computedtomography (CT) scan. The nurse working on the
mm mm mm m mm mm mm mm mm mm mm



oncology unit administers chemotherapy to patients who have cancer. At
mm mm mm mm mm mm mm mm mm mm



the Public Health Department, a nurse administers a measles-mumps-rubella
mm mm mm mm mm mm mm mm mm



(MMR) vaccine to a 14-month-old child as a routine immunization. Which
mm mm mm mm mm mm mm mm mm mm mm



branch of pharmacology best describes the actions of all three nurses?
mm mm mm mm mm mm mm mm mm mm mm




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



involved with clinical pharmacology or pharmacotherapeutics, which is a
mm mm mm mm mm mm mm mm mm



branch of pharmacology that deals with the uses of drugs to treat, prevent,
mm mm mm mm mm mm mm mm mm mm mm mm mm



and diagnose disease.The radiology nurse is administering a drug to help
mm mm mm m mm mm mm mm mm mm mm mm



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



treat a disease. Pharmacoeconomics includes any costs involved in drug
mm mm mm mm mm mm mm mm mm mm



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



pharmacokinetics is how the body acts on the body.

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



a narcotic, every 4 hours as needed for pain in a motor vehicle
mm mm mm mm mm mm mm mm mm mm mm mm mm



accident victim. The nurse is aware this drug has a high abuse
mm mm mm mm mm mm mm mm mm mm mm mm



potential. Under whatcategory would morphine be classified?
mm mm mm m mm mm mm mm




A) Schedule I mm




B) Schedule II mm




C) Schedule III mm




D) Schedule IV mm




ANSWER: B

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



drugs because of severe dependence liability. Schedule I drugs have
mm mm mm mm mm mm mm mm mm mm



high abuse potential and no accepted medical use. Schedule III
mm mm mm mm mm mm mm mm mm mm



drugs have a lesser abuse potential than II and an accepted
mm mm mm mm mm mm mm mm mm mm mm



medical use. Schedule IV drugs havelow abuse potential and
mm mm mm mm mm mm m mm mm mm



limited dependence liability.

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



responsibilitieswould the nurse have?
mm m mm mm mm




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




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




C) Monitoring and observing patients closely for adverse effects

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




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



population in whichpatients are asked to record any symptoms
mm mm mm m mm mm mm mm mm mm



they experience while taking thedrugs. Nurses may be responsible
mm mm mm mm mm m mm mm mm mm



for helping collect and analyze the information to be shared with
mm mm mm mm mm mm mm mm mm mm mm



the Food and Drug Administration (FDA) butwould not conduct
mm mm mm mm mm mm mm m mm mm



research independently because nurses do not prescribe medications.

Select patients who are involved in phase II studies to participate
mm mm mm mm mm mm mm mm mm mm mm



in studies where the participants have the disease the drug is
mm mm mm mm mm mm mm mm mm mm mm



intended to treat. These patients are monitored closely for drug
mm mm mm mm mm mm mm mm mm mm



action and adverse effects. Phase I studies involve healthy human
mm mm mm mm mm mm mm mm mm mm



volunteers who are usually paid for their participation. Nurses may
mm mm mm mm mm mm mm mm mm mm



observe for adverse effects and toxicity.
