A clinic nurse is caring for a 4-year-old client with acute diarrhea and mild dehydration who is afebrile, active, and alert. The nurse is providing instructions to the parent. Which statement by the parent indicates understanding?

A. Intravenous fluids are generally not required if the child is alert and active with mild dehydration; oral rehydration is usually sufficient. B. Oral rehydration solutions are appropriate for treating mild dehydration and should be given in small amounts frequently. C. Chicken broth is not ideal for replacing electrolytes because it is low in electrolytes and high in sodium. Oral rehydration solutions are preferred. D. A depressed soft spot (fontanel) is a sign of severe dehydration in infants. For a 4-year-old, signs of dehydration would include changes in urine output, thirst, or dry mucous membranes rather than a depressed fontanel.
