Delirium occurs in response to all the following stressors except

A. Delirium is an acute, often sudden onset of confusion and altered mental status, usually caused by an underlying medical condition or medication. It tends to fluctuate and is typically reversible — not consistent with the progressive and long-term decline described.
B. Amnesia refers specifically to memory loss, which can be caused by trauma, disease, or psychological factors, but it does not encompass the broader cognitive decline (such as impaired judgment, language, and executive function) seen in dementia.
C. Dementia is characterized by a gradual and progressive decline in memory, thinking, and reasoning skills over time. The two-year progression described in the question is typical of dementia, especially in older adults.
D. Parkinson’s disease is a neurodegenerative disorder primarily affecting movement.While it can be associated with dementia in later stages, the primary symptoms early on are related to motor function (e.g., tremors, rigidity), not memory and cognition.

A. Librium (chlordiazepoxide) is a benzodiazepine commonly used to manage alcohol withdrawal symptoms, such as agitation, tremors, and seizures.
B. Valium (diazepam) is another benzodiazepine frequently used for alcohol withdrawal due to its long half-life and calming effects.
C. Ativan (lorazepam) is also used in alcohol withdrawal treatment, especially for patients with liver issues, as it has a shorter half-life and is metabolized differently than other benzodiazepines.
D. Zoloft (sertraline) is an SSRI antidepressant, not used for managing acute alcohol withdrawal. While it may be prescribed later for co-occurring depression or anxiety, it is not appropriate for immediate withdrawal management.
