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


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

routine immunization. Which branch ofpharmacologybest describes the actions of all
t t t t t t t t t t t


three nurses?

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


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


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


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


administering a drug to help treat a disease. Pharmacoeconomics includes any costs
t t t t t t t t t t t t


involved in drug therapy. Pharmacodynamics involves how a drug affects the body
t t t t t t t t t t t t


and pharmacokinetics is how the body acts on the body.

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


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

what category would morphine be classified?

A) Schedule I t



B) Schedule II t




C) Schedule III t




D) Schedule IV t




ANSWER: B

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


tbecause of severe dependence liability. Schedule I drugs have high abuse
t t t t t t t t t t


tpotential and no accepted medical use. Schedule III drugs have a
t t t t t t t t t t


tlesser abuse potential than II and an accepted medical use. Schedule IV
t t t t t t t t t t t


tdrugs have low abuse potential and limited dependence liability.

would the nurse have?

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




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




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




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




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


twhich patients are asked to record any symptoms they experience while
t t t t t t t t t t


ttaking the drugs. Nurses may be responsible for helping collect and
t t t t t t t t t t


t analyze the information to be shared with the Food and Drug
t t t t t t t t t t


tAdministration (FDA) but would not conduct research independently t t t t t t t


tbecause nurses do not prescribe medications. Use of animals in drug
t t t t t t t t t t


t testing is done in the preclinical trials. Select patients who are involved in
t t t t t t t t t t t t


tphase II studies to participate in studies where the participants have the
t t t t t t t t t t t


tdisease the drug is intended to treat. These patients are monitored closely
t t t t t t t t t t t


tfor drug action and adverse effects. Phase I studies involve healthy
t t t t t t t t t t


human volunteers who are usually paid for their participation. Nurses
t t t t t t t t t


may observe for adverse effects and toxicity.
