Cognitive Level: Application Difficulty: Moderate Integrated Process: Nursing process 1.A nurse working in radiology administers iodine to a patient who is having a computerized axial tomography (CAT) scan. A nurse working on an 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 Response: 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 nurse working in radiology is administering a drug to help diagnose a disease. The nurse working on an oncology unit 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 drug.

The nurse is aware that there is a high abuse potential for this drug; therefore, morphine is categorized as a: A) Schedule I drug B) Schedule II drug C) Schedule III drug D) Schedule IV drug ANSWER: B Response: Narcotics such as morphine are considered schedule II drugs because of the high abuse potential with severe dependence liability. Schedule I drugs have high abuse potential and no accepted medical use. Schedule III drugs have a lesser abuse potential than schedule II drugs and an accepted medical use. Schedule IV drugs have low abuse potential and limited dependence liability.

Which of the following might the nurse be responsible for during this stage of drug development? Chapter 1: Introduction to Drugs A) Working with animals who are given experimental drugs B) Monitoring drug effects in patients who are selected to participate in a study, who have the disease that the drug is meant to treat C) Collecting records of symptoms that participants experience while taking a drug and determining whether they are caused by the disease or the drug D) Informing healthy, young volunteer participants of possible risks that could occur from taking an experimental drug ANSWER: C Response: Phase III studies involve use of a drug in a vast clinical market where patients are asked to record any 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). Use of animals in drug testing is done in the preclinical trials. A select group of patients who are involved in phase II studies participate in studies where the participants have the disease the drug is intended to treat. These patients are monitored closely for drug effects. Phase I studies involve healthy human volunteers who are usually paid for their participation. Nurses may observe for adverse effects and toxicity. Cognitive Level: Comprehension Difficulty: Moderate Integrated Process: Nursing Process
