1. A nurse working in radiology administers iodine to a client who is having a computed tomography (CT) scan. The nurse working on the oncology unit administers chemotherapy to clients 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. The care provider has prescribed intravenous hydromorphone, an opioid, for a client using a client-controlled analgesia (PCA) pump. The nurse is aware that this drug has a high abuse potential. Under what category would hydromorphone be classified? A) Schedule I B) Schedule II C) Schedule III D) Schedule IV Ans: B Feedback: Opioids 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 schedule II drugs and an accepted medical use. Schedule IV drugs have low abuse potential and limited dependence liability. 3. When involved in phase III drug evaluation studies, what action should the nurse perform? A) Work with animals which are given experimental drugs. B) Select appropriate clients to be involved in the drug study. C) Monitor and observe clients closely for adverse effects. D) Make decisions that will determine effectiveness of the drug. Ans: C Feedback: Phase III studies involve use of a drug in a vast clinical population in which clients 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) 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 clients who are involved in phase II studies to participate in studies where the participants have the disease the drug is intended to treat. These clients are monitored closely for drug action and adverse effects. Phase I studies involve healthy human volunteers who are usually paid for their participation. Nurses may observe for adverse effects and toxicity.
