What is the primary goal of a fluid restriction of 1 liter per day in edema management?

• A. To increase urine output
• B. To reduce fluid intake to decrease edema
• C. To replace electrolytes
• D. To hydrate cells

Answer: (B)

Limiting daily fluid intake to a specific amount aims to reduce the total amount of fluid the body has to handle, which helps lessen the excess fluid trapped in tissues that causes edema. In edema, fluid accumulates in the interstitial spaces due to imbalances in how fluids move between compartments. By restricting intake to 1 liter per day, you decrease the incoming fluid, making it easier for the kidneys to maintain balance and for the interstitial fluid to be mobilized back into the circulation, thereby reducing swelling over time. This approach is not about forcing more urine out or replacing electrolytes with fluids. Increasing urine output would come from diuretics or other interventions, not from simply restricting intake. Replacing electrolytes is a separate concern related to electrolyte balance, not the primary aim of restricting fluids. Hydrating the cells by increasing fluid intake would worsen edema.
