What is the treatment for dehydration due to FVD?

• A. Oral rehydration and IV solutions
• B. Fluid restrictions
• C. High-sodium diet
• D. Diuretics

Answer: (A)

Restoring fluid volume and correcting electrolyte balance is the goal when the body has a fluid volume deficit causing dehydration. This is best achieved with rehydration using oral rehydration solutions or IV fluids, chosen based on how much fluid is lost and whether the person can drink. Oral rehydration, which contains the right mix of water, electrolytes (especially sodium), and glucose, works well for mild to moderate dehydration and helps promote gut absorption. If the person cannot take fluids by mouth or if there are signs of severe dehydration (poor perfusion, rapid heartbeat, very low blood pressure, confusion), IV fluids such as isotonic saline or lactated Ringer’s solution are used to rapidly restore volume.

Fluid restrictions would worsen dehydration, a high-sodium diet is not a prompt rehydration strategy and can worsen fluid shifts, and diuretics remove fluid rather than replenish it, making them inappropriate for treating dehydration due to volume deficit.
