What is the recommended fluid intake for immobile adults?

• A. At least 1100 to 1400 mL of non-caffeinated fluids daily
• B. 500 mL daily
• C. Any amount as long as hydration is maintained
• D. Only water intake is necessary

Answer: (A)

Immobilized patients are at higher risk for dehydration because thirst perception can be blunted and fluid needs may be increased by factors like medications, fever, or wound healing. Providing a reliable daily fluid target helps protect kidney function, prevent constipation, and reduce the risk of urinary tract infections. The best answer sets a practical, evidence-based goal: at least 1100 to 1400 mL of non-caffeinated fluids each day. Choosing non-caffeinated fluids minimizes potential diuretic effects that could undermine hydration, while fluids can come from water, milk, juice, broth, and similar sources. The other options fall short or misrepresent how hydration works: 500 mL daily is not enough to meet needs; hydration isn’t upheld by “any amount” when a patient is immobile; and limiting to only water ignores the variety of fluids that contribute to total intake.
