Final answer:
The correct fluid restriction for a client with chronic renal failure on hemodialysis is the amount of daily urine output plus 1200 to 1500 mL, to balance the risk of dehydration and fluid overload.
Step-by-step explanation:
A nurse explaining the concept of fluid restriction to a client with chronic renal failure who has started hemodialysis would tell the client that the fluid restriction is planned by adding the amount of the daily urine output (if any) to: b) 1200 to 1500 ml.
The kidneys must produce a minimum urine volume of about 500 mL/day to rid the body of wastes properly. However, for a patient on hemodialysis, fluid intake must be controlled to avoid fluid overload, which can lead to complications such as hypertension and pulmonary edema. By restricting fluid intake to the amount of urine produced plus an additional 1200 to 1500 mL, the nurse aims to balance the need to avoid dehydration while preventing fluid overload.
