A nurse is caring for a child who has acute diarrhea and reports that he is thirsty. Which of the following fluids should the nurse give the child?

Choice A reason: Acute diarrhea causes fluid and electrolyte loss, leading to dehydration. Pedialyte, an oral rehydration solution, contains balanced glucose, sodium, and potassium, facilitating water absorption via sodium-glucose cotransport in the intestine. This corrects dehydration and electrolyte imbalances, making it the optimal fluid for a thirsty child with diarrhea. Choice B reason: Cherry gelatin lacks the balanced electrolytes needed for rehydration in acute diarrhea. It contains sugar, which may worsen osmotic diarrhea by drawing water into the intestine. Unlike Pedialyte, gelatin does not restore sodium or potassium losses, making it ineffective for correcting dehydration and potentially exacerbating fluid loss. Choice C reason: Broth is high in sodium but lacks balanced electrolytes and glucose for optimal rehydration in diarrhea. It may not adequately replace potassium or promote intestinal water absorption. Pedialyte’s balanced composition better corrects fluid and electrolyte deficits, making broth a less effective choice for a dehydrated child. Choice D reason: Apple juice has high sugar content, which can worsen diarrhea via osmotic effects, drawing water into the intestine and increasing stool volume. It lacks balanced electrolytes for rehydration. Pedialyte’s specific sodium-glucose ratio enhances water absorption, making apple juice inappropriate for managing dehydration in a child with diarrhea.
