Which action best supports safety and reduces confusion in an older adult with dehydration-related delirium-like symptoms?

• A. Providing fluids and gentle orientation
• B. Isolating the patient to prevent wandering
• C. Withholding fluids to monitor intake
• D. Restraint to prevent injury

Answer: (C)

Dehydration-related delirium stems from reduced fluid volume affecting brain function, so the priority is to correct the underlying cause while supporting safety. Providing fluids helps restore circulating volume and cerebral perfusion, which can lessen confusion and improve cognitive clarity. Pairing hydration with gentle orientation helps the person recognize where they are, understand what’s happening, and feel more secure, which reduces agitation and wandering without restricting movement.

Isolating the patient to prevent wandering, withholding fluids to monitor intake, or using restraints all pose safety and ethical concerns and can worsen delirium. Isolation can increase confusion and fear; withholding fluids prolongs the delirium and increases risk of complications from dehydration; restraints can cause physical harm and heighten agitation.

In this scenario, rehydration plus gentle, respectful orientation addresses the root cause and supports safety more effectively than the other approaches.
