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 radiol ogy 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 phar macokinetics is how the body acts on the body.

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) shedule 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.

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 o f the drug. Ans: C Feedback: Phase III studies involve use of a drug in a larger sample of the population. The purpose is to determine the treatment benefit and to monitor side effects that may not have been apparent in the earlier studies. Phase I studies involve healthy human volun teers who are usually paid for their participation. Nurses may observe for adv erse effects and toxicity. Nurses may be responsible for helping collect and analyze the information to be shared with the Food and Drug Administ ration (FDA) but would n ot 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 i nvolved in phase II studies have the disease the drug is intended to treat. These clien ts are monitored closely for drug action and adverse effect s.

What concept is prioritized when a provider is considering the substitution of brand name drug with a generic drug? A) bioequivalency B) critical concentration Document shared on https://www.docsity.com/en/test- bank-for-karch-s-focus-on-nursing-pharmacology-9th- edition-by-rebecca-tucker/10381517/ 4 C) distribution D) half -life Ans: A Feedback: The goal is that the generic medication is bioequivalent (has the same effect on the body) to the brand name medication. Binders used in a generic drug may not be the same as those used in the brand name drug. Therefore, the way the body brea ks down and u ses the drug may differ, which may eliminate a generic drug substitution. Critical concentration is the amount of a drug that is needed to cause a therapeutic effect and should not differ between generic and brand name medications. Distribution is the phase of pharmacokinetics, which involves the movement of a drug to th e body’s tissues and is the same in generic and brand name drugs. A drug’s half -life is the time it takes for the amount of drug to decrease to half the peak level, which should n ot change when substituting a generic medication.

A nurse is assessing the client’s home medication use. After listening to the cl ient list current medications, the nurse asks what priority question? A) “Do you take any generic medications?” B) “Are any of these medications orphan drugs?” C) “Are these medications safe to take during pregnancy?” D) “Do you take any over -the-counter medications?” Ans: D Document shared on https://www.docsity.com/en/test- bank-for-karch-s-focus-on-nursing-pharmacology-9th- edition-by-rebecca-tucker/10381517/
