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 adisease. Pharmacoeconomics includes any costs involved in drug therapy. Pharmacodynamics involves how a drug affects the body, and pharmacokinetics ishow the body acts on the drug.

The nurse is aware thatthere 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 havelow abuse potential and limited dependence liability.

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 adrug and determining whether they are caused by the disease or the drug D) Informing healthy, young volunteer participants of possible risks that couldoccur 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 beresponsible 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: ComprehensionDifficulty: Moderate Integrated Process: Nursing Process 4.Which of the following concepts is considered when generic drugs are substituted forbrand-name drugs? A) Bioavailability B) Critical concentration C) Distribution D) Half-life ANSWER: A Response: 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 downand uses the drug may differ, which may eliminate a substitution. Critical concentration is the amount of a drug that is needed to cause a therapeutic effect. Distribution is the phase of pharmacokinetics that involves the movement of a drug tothe body's tissues. A drug's half-life is the time it takes for the amount of drug to decrease to one-half of the peak level. Cognitive Level: Analysis Difficulty: Difficult Integrated Process: Teaching/learning 5.A nurse is teaching her patient about the use of over-the-counter (OTC) drugs. Whichof the following statements best informs the patient about their safe use? A) “OTC drugs are products that are available without prescription for self-treatment of minor complaints.” B) “OTC drugs are considered medications and should be reported on a drughistory.” Chapter 1: Introduction to Drugs C) “OTC drugs were approved as prescription drugs but later were found to besafe without the need for a prescription.” D) “OTC drugs need to be taken with caution. They can mask the signs and symptoms of an underlying disease and interfere with prescription drug therapy.” ANSWER: D Response: OTC drugs are considered medications and should be reported. OTC drugs are available without a prescription, although some were first approved as prescription drugs. The most important teaching should relate to their safe use and that OTC drugscan mask symptoms of disease and interfere with prescribed drugs.

A) Pure Food and Drug Act of 1906 B) Federal Food, Drug, and Cosmetic Act of 1938 C) Durham Humphrey Amendment of 1951 D) Kefauver-Harris Act of 1962 ANSWER: D Response: The Kefauver-Harris Act was the result of the use of the 1960s drug thalidomide (Thalomid). The public concern led to the legislation that gave the FDA regulatory control over testing and evaluating of drugs and allowed it to set standards for efficacy and safety. The Pure Food and Drug Act required labeling to eliminate falseclaims. The Federal Food, Drug, and Cosmetic Act gave the FDA the power to enforce standards for testing drug toxicity and monitoring labeling. The Durham- Humphrey Amendment enforced prescriptions for distribution.
