A client reports that the narcotic she took for pain on a regular basis made her feel bad and that when she tried an alternative analgesic, she experienced withdrawal symptoms. What is this client suffering from?

Choice A reason: Drug dependence, or physical dependence, is a physiological state where the body has adapted to the presence of a drug. The hallmark of dependence is the emergence of withdrawal symptoms when the substance is discontinued. This can occur even when a drug is taken exactly as prescribed. Choice B reason: Drug addiction (substance use disorder) involves behavioral components such as compulsive use, loss of control over consumption, and continued use despite harmful consequences. The patient’s report that the drug "made her feel bad" suggests a lack of the psychological "craving" or reward-seeking behavior typical of addiction. Choice C reason: Substance abuse traditionally refers to the use of a substance in a way that is inconsistent with legal or medical guidelines, often resulting in social or occupational impairment. The scenario describes a physiological reaction to stopping a medication, which is a medical phenomenon rather than a behavioral pattern. Choice D reason: Drug abuse is a general term for the improper use of substances. Since the client was taking the narcotic "for pain," likely under medical supervision, and stopped it because it made her feel bad, her situation is a matter of physiological dependence rather than intentional misuse or abuse.
