1. A nurse working in radiology administers iodine to a patient who is having a
computedtomography (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
ANSWER: 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
