Following involvement in a motor vehicle collision, a middle-aged adult client is admitted to the hospital with multiple facial fractures. The client's blood alcohol level is high on admission. Which PRN prescription should be administered if the client begins to exhibit signs and symptoms of delirium tremens (DTs)?

Choice A reason: Hydromorphone, an opioid, is used for pain, not delirium tremens (DTs), which requires benzodiazepines to manage withdrawal symptoms like tremors and seizures. Opioids may worsen respiratory depression in alcohol withdrawal, making this incorrect for treating DTs in this client with high alcohol levels.Choice B reason: Lorazepam, a benzodiazepine, is the standard treatment for delirium tremens, as it reduces agitation, seizures, and autonomic instability in alcohol withdrawal. Its PRN use is appropriate for managing DTs symptoms, aligning with addiction medicine guidelines, making it the correct choice for this client.Choice C reason: Prochlorperazine, an antiemetic, treats nausea but not DTs, which involves severe neurological and autonomic symptoms. Benzodiazepines like lorazepam are needed to prevent seizures and calm withdrawal. This medication is inappropriate, making it incorrect for managing alcohol withdrawal complications.Choice D reason: Chlorpromazine, an antipsychotic, may lower seizure threshold, worsening DTs. Benzodiazepines like lorazepam are first-line for alcohol withdrawal to manage symptoms safely. Chlorpromazine is not indicated, making this incorrect for treating delirium tremens in a client with alcohol-related withdrawal.
