A 29-month-old child who is dehydrated as a result of vomiting requires oral rehydration. which concept regarding oral rehydration therapy should the nurse consider?

Give an oral rehydration solution. Rational: Oral rehydration solutions are successful in treating the majority of children with isotonic, hypotonic, or hypertonic dehydration. Clear liquids such as fruit juices and gelatin are not used for rehydration because of their high carbohydrate content, very low electrolyte content, and high osmolality.
