A nurse is caring for a client who is experiencing manifestations of alcohol withdrawal. Which of the following medications should the nurse plan to administer?

Introduction: Alcohol withdrawal syndrome occurs when abrupt cessation of ethanol intake causes a rebound of the central nervous system. This state of neuro-excitability requires pharmacological intervention with agents that enhance gamma-aminobutyric acid (GABA) activity to prevent life-threatening complications such as generalized tonic-clonic seizures and delirium tremens. A. Methadone is a synthetic opioid agonist utilized primarily for the management of opioid use disorder and chronic pain. It acts on the mu-opioid receptors to prevent withdrawal symptoms from heroin or prescription narcotics. It has no pharmacological role in stabilizing the neurochemical imbalances or autonomic hyperactivity associated specifically with alcohol withdrawal syndrome. B. Clozapine is an atypical antipsychotic medication used for treatment-resistant schizophrenia. While it effectively manages psychotic symptoms, it is contraindicated in acute withdrawal states because it significantly lowers the seizure threshold. In the context of alcohol withdrawal, where seizure risk is already high, administering clozapine would be clinically dangerous and inappropriate. C. Lorazepam is a benzodiazepine and the gold standard for treating alcohol withdrawal. It provides cross-tolerance with alcohol by enhancing the inhibitory effects of GABA. This stabilization of the central nervous system prevents autonomic surge, reduces the severity of tremors and agitation, and effectively raises the seizure threshold during the critical withdrawal period. D. Bupropion is an antidepressant often used as a smoking cessation aid. It works by inhibiting the reuptake of norepinephrine and dopamine. Like clozapine, bupropion is known to lower the seizure threshold, especially in high doses or vulnerable populations, making it an unsafe choice for a client currently undergoing acute alcohol withdrawal.
