What is the use of oral rehydration solutions?

• A. To treat infections.
• B. To treat dehydration by restoring fluid and electrolytes.
• C. To provide vitamins and minerals.
• D. To inhibit gastric secretions.

Answer: (B)

Oral rehydration solutions are specifically designed to address the needs of individuals suffering from dehydration, particularly due to conditions such as diarrhea or vomiting. They work by restoring both fluids and essential electrolytes—such as sodium and potassium—that are lost during these conditions.

The formulation of oral rehydration solutions is carefully balanced to enhance the absorption of water and electrolytes in the intestines, which is crucial for rehydration. This rapid rehydration is vital in preventing complications related to dehydration, especially in vulnerable populations like children and the elderly.

The other options, such as treating infections, providing vitamins, or inhibiting gastric secretions, do not capture the primary purpose of oral rehydration solutions, which is focused solely on rehydration and electrolyte balance.
