NURSING PHARMACOLOGY NUR120 Pharma chapter 2 quiz 1

Question 1 of 20 A group of students are reviewing class material in preparation for a test. The students demonstrate a need for additional teaching when they identify which of the following as part of phase I biotransformation? • Conjugation • Hydrolysis • Oxidation • Reduction Question 2 of 20 A client is receiving 250 mg of a drug that has a half-life of 12 hours. How much drug would remain after 36 hours? • 125 mg • 16 mg • 63 mg • 31 mg Question 3 of 20 The nurse is preparing to administer a prescribed drug to a client with a history of renal disease. Why should the nurse anticipate administering a lower dose than for a client with healthy kidneys? • Distribution will be delayed, increasing the risk of adverse effects. • The client likely has impaired drug metabolism. • Absorption will be increased because of fluid accumulation. • Excretion is likely to take place slowly. Question 4 of 20 An experienced nurse has observed that female clients sometimes experience a drug’s effects for a longer time than male clients of similar age and size. The nurse should attribute this to what factor? • Women have more fat cells so drugs depositing in fat will have a prolonged effect. • Men commonly lack certain enzyme systems that are necessary for metabolizing a drug. • Women more often experience electrolyte imbalances, prolonging a drug's effect. • Men have more vascular muscle so drug effects will take longer to occur. Question 5 of 20 A client has developed a tolerance to a drug. How should the nurse address this when providing care? • Advocate for a change in the client’s medication. • Assess the client for signs and symptoms of adverse drug effects. • Assess the client for signs and symptoms of an allergy to the drug. • Assess whether the client needs larger doses to achieve the effect. Question 6 of 20 A client is administered an oral contraceptive. What is the process that occurs between the time the drug enters the body and the time it enters the bloodstream? • excretion • absorption • distribution • metabolism Question 7 of 20 Which factor accounts for the increased risk for drug reactions among clients aged 65 years and older? • drugs more readily crossing the blood–brain barrier in older people • physiologic changes affecting all pharmacokinetic processes • increased drug-metabolizing enzymes in older people • diminished immune response Question 8 of 20 A 38-year-old client is obese and has abscesses around the inner thigh muscles. The client is receiving IV antibiotics, but no improvement has been seen. The client questions the nurse about the most likely cause for the drug therapy failure. The nurse explains that the: • distribution of the drug to the thigh muscles is generally impaired, even in healthy individuals. • surface area of the abscesses is not large enough for the drug to have the desired therapeutic effect. • route of administering the medication should not have been IV. • distribution of the drug to the area of the abscesses is impaired. Question 9 of 20 A 72-year-old man with pain issues is being given a drug by the intramuscular route. His serum blood level concentrations have been erratic. The nurse suspects that this may be due to • decreased gastrointestinal motility. • increased levels of plasma albumin. • decreased blood flow to tissues and muscles. • altered gastric pH levels. Question 10 of 20 A client will soon be discharged home from the hospital after a successful coronary artery bypass graft (CABG). During client education about drug regimen, the nurse should prioritize teaching about: • the need to have a younger family member oversee drug administration. • the balance between benefits and risks that underlies the drug regimen. • potential adverse effects of the drugs that the client will be taking. • the age-related changes that influence the health care provider's choice of medications. Question 11 of 20 A nurse is conducting an assessment of a client who has recently had several changes made to the drug regimen. What assessment question most directly addresses the safety implications of the client's drug regimen? • “Do you prefer to take liquid medications or are you fine with taking pills?” • “What effect are you expecting that these medications will have on your health?” • “Which pharmacy do you use to fill your prescriptions?” • “Do you take any herbal supplements or alternative medications?” Question 12 of 20 A nurse is aware that older adults tend to have a significantly decreased rate of hepatic blood flow compared with younger adults. What effect is this likely to have on pharmacokinetics and pharmacodynamics in an older adult? • Drug clearance is likely to be slower. • Multiple bioactive substances will be needed for therapeutic effect. • Elimination half-time is likely to be faster. • The kidneys will likely compensate for decreased hepatic capacity. Question 13 of 20 Drug evaluation studies are used to determine critical concentration. The nurse understands that the critical concentration is the amount of the drug needed to cause: • toxic effect. • minimal effect. • therapeutic effect. • lethal effect. Question 14 of 20 Drugs injected intravenously (IV) reach their full strength in which timeframe? • 30 minutes • 20 minutes • 10 minutes • Immediately Question 15 of 20 Drug excretion occurs mainly in which organ? • liver • small intestine • pancreas • kidneys Question 17 of 20 When a drug is given at a stable dose, how many half-life periods are required to achieve steady-state concentrations and develop equilibrium between tissue and serum concentrations? • 2 to 3 • 5 to 6 • 4 to 5 • 3 to 4 Question 18 of 20 A drug is 100% bioavailable when it is administered by what routes? • oral • rectal • parenteral • intravenous Question 19 of 20 What is the expected therapeutic outcome of the simultaneous administration of two medications? • The combined effects are greater than the effects of either one of the drugs alone. • The adverse effects of one of the drugs are nullified by the other drug. • One of the drugs enhances metabolism, while the other drug enhances either distribution or absorption. • Both drugs are toxic in isolation but therapeutic when administered together. Question 20 of 20 The nurse educates an older adult about the seven prescribed medications to prevent medication-related reactions and adverse effects. Which client statement indicates the need for further clarification? • “I will ask my prescriber or pharmacist before taking any over-the-counter (OTC) drug or herbal.” • “The dietary supplement I used to take before admission to the hospital is alright to restart.” • “Reporting any listed adverse reactions to my prescriber right away is important.” • “I will use the same pharmacy to buy all my drugs, so the pharmacist can check for interactions.” Question 1 See full question 1m 55s A group of students are reviewing class material in preparation for a test. The students demonstrate a need for additional teaching when they identify which of the following as part of phase I biotransformation?
