Which statement correctly describes the purpose of an oral rehydration solution in diarrhoeal illness?

• A. To replace water and essential electrolytes
• B. To cure the underlying infection
• C. To provide complete nutrition until fluids are restored
• D. To induce diarrhoea to flush the gut

Answer: (A)

The purpose of an oral rehydration solution in diarrhoeal illness is to restore fluid balance and replace the essential electrolytes lost through the stool. It’s formulated to hydrate the body and correct electrolyte abnormalities, with the glucose component helping the intestines absorb sodium and water more efficiently, speeding rehydration. This addresses the main danger of diarrhoea—the dehydration and electrolyte loss—not to cure the infection itself. It isn’t intended to provide complete nutrition, and it doesn’t aim to induce diarrhoea.
