A patient with chronic alcoholism is admitted for severe agitation, visual disturbances, and diaphoresis 60 hours after cessation of alcohol intake. The ECG shows sinus tachycardia. Which medication should be prioritized to address the patient's current condition?
Administer magnesium sulfate intravenously.
Give haloperidol to control visual hallucinations.
Provide aggressive intravenous fluid rehydration.
Administer a loading dose of intravenous benzodiazepines.
The patient is likely experiencing alcohol withdrawal syndrome, specifically with symptoms suggesting delirium tremens, which is a serious and potentially fatal condition. The immediate administration of benzodiazepines is key to managing the symptoms, preventing seizures, and reducing the risk of mortality. Administering magnesium sulfate as a first-line treatment is incorrect because it does not directly address the withdrawal symptoms, though it may be used adjunctively to manage associated hypomagnesemia. Providing intravenous fluids without benzodiazepines would not sufficiently treat the withdrawal symptoms, and haloperidol, an antipsychotic, can lower the seizure threshold and is not the first-line treatment for delirium tremens.
