Which practice best aligns with preventing delirium in hospitalized older adults?

• A. Limit hydration to reduce urinary frequency and isolate patient to minimize stimuli.
• B. Avoid sleep and increase noise to keep patient awake.
• C. Rely solely on pharmacologic sedation to manage agitation.
• D. Ensure hydration and nutrition, promote sleep hygiene, provide orientation cues, minimize polypharmacy, encourage mobility, and use CAM tools for assessment.

Answer: (D)

Preventing delirium in hospitalized older adults comes from a broad, nondrug approach that tackles multiple risk factors at once. Keeping patients well hydrated and well nourished supports brain function and reduces the irritants that can spark confusion. Promoting good sleep hygiene helps protect cognition, since wakefulness and rest cycles strongly influence delirium risk. Providing orientation cues—like clocks, calendars, and familiar routines—helps patients stay anchored in reality. Minimizing polypharmacy reduces exposure to medications that can provoke delirium, especially anticholinergics and sedatives. Encouraging mobility, as feasible, maintains physical and cognitive function and lowers delirium risk related to immobility. Using validated tools to assess for delirium, such as the Confusion Assessment Method (CAM), allows early detection and timely management.

Pharmacologic sedation alone is not the right approach because it can mask symptoms and often worsens delirium or delays proper treatment. The combination of hydration, nutrition, sleep, orientation, reduced unnecessary medications, mobility, and careful monitoring best aligns with preventing delirium.
