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
Pharmacotherapeus
Pharmacodynamics
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 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
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 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
Ans: 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
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,
