A nurse is caring for a child who has had diarrhea for 3 days.Which of the following actions should the nurse take?

Choice A rationaleCollecting a stool culture identifies the causative agent for diarrhea, such as bacterial or parasitic infection. This diagnostic measure is critical for initiating targeted treatment and preventing complications like dehydration or prolonged gastrointestinal disturbance.Choice B rationaleApple juice contains high fructose content, which can exacerbate diarrhea through osmotic effects. Offering oral rehydration solutions instead ensures electrolyte and fluid balance without worsening symptoms of diarrhea.Choice C rationaleNPO status for extended periods may cause further dehydration and nutritional deficits in children. Continuing feeding with appropriate fluids or foods supports recovery and gut mucosal health during diarrheal illness.Choice D rationaleWeekly weight monitoring does not address acute concerns of dehydration and electrolyte imbalance associated with diarrhea. Daily weights provide more timely data on fluid loss in pediatric patients with ongoing diarrhea. .
