DIF:Cognitive Level: KnowingREF:p. 245.A patient is given a drug that is a known agonist. How would you expect this drug to work?a.This drug works by attaching to the receptor site to activate it.b.This drug works by deactivation of all cellular receptor sites.c.This drug works to partially block receptor sites.d.This drug works by interacting with other drugs.ANS:AA drug agonist works by activating or unlocking receptors, and has the same actions as thebody’s own chemicals.DIF:Cognitive Level: KnowingREF:p. 246.You are giving an oral drug to a patient. For this drug to be utilized by the body, whichmechanism is the first to be involved in that process?a.Excretionb.Absorptionc.Metabolismd.DistributionANS:BAbsorption involves the way a drug enters the body and passes into the body and tissues.

What is your best response?a.“Water is important for proper metabolism.”b.“Juice or milk can keep it from dissolving.”c.“Water helps to dissolve the drug.”d.“Water keeps the drug potent.”ANS:CAll drugs must be dissolved in body fluid before they enter body tissues.

What is your best response?a.“Many oral drugs are inactivated as you get older.”b.“Your liver disease impairs the transformation of a drug into its active form.”c.“Intravenous drugs reduce toxicity to the liver through first-pass metabolism.”d.“Individuals with liver disease have a genetic impairment that prevents drugactivation.”ANS:BMany drugs must be activated by enzymes before they can be used in the body. Thisbiotransformation happens in the liver. Liver disease impairs this process.DIF:Cognitive Level: ApplyingREF:pp. 25-2611.A patient who is beginning a new cholesterol-lowering drug tells you he plans to take thisdrug in the evening with his usual glass of grapefruit juice. What is your best response?a.“The vitamin C in grapefruit juice enhances the action of cholesterol-loweringdrugs.”b.“The acid environment of grapefruit juice promotes drug metabolism.”c.“Taking grapefruit juice can reduce the effectiveness of the drug.”d.“Taking grapefruit juice can increase the absorption of the drug.”ANS:CGrapefruit juice affects (usually reduces) the absorption of many drugs such as antihistamines,cholesterol-lowering drugs, HIV drugs, and transplant drugs.DIF:Cognitive Level: ApplyingREF:p. 2612.You give a patient 400 mg of an oral drug at noon.

Adverse reactions, oradverse effects, usually imply more severe symptoms or problems that develop because of thedrug.DIF:Cognitive Level: ApplyingREF:p. 2714.A patient tells you that she is experiencing sleepiness after taking a drug prescribed for backpain. What is your best response?a.“You are having a severe drug interaction.”b.“You are having an expected drug side effect.”c.“You are having the desired effect of this drug.”d.“You are having an idiosyncratic response to this drug”.ANS:BDrugs may influence many body systems at the same time, so the effect of the drug is oftennot restricted to the desired action. Side effects are usually seen as mild but annoyingresponses to the drug. In the case of many drugs for pain, sleepiness is an expected side effect.DIF:Cognitive Level: ApplyingREF:p. 2715.A patient who was given intravenous penicillin for a severe infection develops hives, itching,and facial swelling immediately after the infusion. What type of drug reaction is this patientexperiencing?a.An adverse reactionb.A paradoxical reactionc.An anaphylactic reactiond.A hypersensitivity reactionANS:DSome drugs (sulfa products, aspirin, and penicillin) can produce allergic (hypersensitivity)reactions that usually occur when an individual has taken the drug and the body has developedantibodies to it.DIF:Cognitive Level: KnowingREF:p. 2716.What information should be included in the teaching plan for a young woman who has begunon a 10-day course of oral antibiotic therapy for an infection?
