A client with chronic renal failure must restrict her fluid intake to 500 ml daily. Despite having reached the limit, the client is insisting that she have more fluid. Which intervention by a nurse is appropriate?

• A. Allow her to have a piece of hard candy
• B. Offer a sugar-free soda
• C. Provide a glass of water
• D. Allow ice chips only

Answer: (A)

Managing thirst in a fluid-restricted client means offering options that satisfy the urge to drink without adding to the verified fluid intake. A piece of hard candy helps with thirst and dry mouth by providing oral moisture and stimulation, yet it contributes essentially no measurable fluid to the daily limit.

Allowing a glass of water or a sugar-free soda would increase total fluid intake and could exceed the prescribed 500 ml limit. Providing ice chips, while common for comfort, still counts toward the fluid restriction since the ice will melt into liquid and add to the daily volume.
