1. 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?
A) Pharmacoeconomics
B) Pharmacotherapeutics
C) Pharmacodynamics
D) 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 of drugs 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 a drug affects the body and
pharmacokinetics is how the body acts on the body.
2. A physician has ordered intramuscular (IM) injections of morphine, a
narcotic, every 4 hours as needed for pain in a motor vehicle accident
victim. The nurse is aware this drug has a high abuse potential. Under what
category would morphine be classified?
A) Schedule I
B) Schedule II
C) Schedule III
D) Schedule IV
Ans: B
, Feedback:
Narcotics awith aa ahigh aabuse apotential aare aclassified aas aSchedule aII
adrugs abecause aof asevere adependence aliability. aSchedule aI adrugs ahave
ahigh aabuse apotential a and a no aaccepted amedical a use. a Schedule a III
a drugs a have a a alesser aabuse apotential athan aII aand aan aaccepted amedical
ause. aSchedule aIV adrugs ahave alow aabuse apotential aand alimited
adependence aliability.
