PHARM EXAM 4 TEST BANK with perfect answers 2024

A nurse is teaching a group of nursing students about substance abuse. Which statement by a student indicates a need for further teaching? "Patients who experience physical dependence will show compulsive drug-seeking behavior." "People who are addicted to a drug do not necessarily have tolerance to that drug." "Physical dependence means that abstinence syndrome will occur if a drug is withdrawn." "Physical dependence often contributes to addictive behavior but does not cause it." correct answersANS: A Physical dependence occurs with prolonged drug exposure and, through neuroadaptive processes, results in abstinence syndrome if a drug is withdrawn. It does not necessarily result in compulsive drug-seeking behavior. Patients can have drug addiction, which involves compulsive drug seeking without having developed a tolerance to drug effects. Addictive behavior is the result of psychologic dependence with an intense subjective need for a drug. Because abstinence syndrome is uncomfortable, physical dependence can increase subjective feelings for a drug. A patient is ready for discharge home from a lengthy hospital stay after a motor vehicle accident. The patient suffered multiple fractures and required large doses of morphine for several weeks. The nurse preparing the patient for discharge notes that the patient requests the maximum dose of the oral opioid analgesic at the exact intervals it is prescribed. The nurse is correct to suspect what has occurred? Addiction Compulsive drug seeking Cross-tolerance Drug tolerance correct answersANS: D Patients who use a drug regularly develop tolerance to the drug when a dose produces a smaller response than it did initially. This patient has been on large doses of opioids for several weeks and has developed tolerance to this class of drugs. Addiction is characterized by compulsive drug seeking, which has not occurred. A patient using narcotics for severe pain is not a compulsive drug seeker. Cross-tolerance occurs when tolerance to one drug confers tolerance to another drug. The opioid analgesic for home use is in the same drug classification, so this is not cross- tolerance. A patient who has been taking a medication with a side effect of drowsiness stops taking the medication after several weeks. The patient reports feeling anxious and jittery. The nurse understands that this response is due to: addiction. psychologic dependence. tolerance. withdrawal syndrome. correct answersANS: D
