A nurse is caring for a child who has acute gastroenteritis but is able to tolerate oral fluids. The nurse should provide the following type of fluid to the child.

Choice A rationale Water alone does not contain the necessary electrolytes, such as sodium, potassium, and chloride, which are lost during vomiting and diarrhea associated with gastroenteritis. Providing only water can worsen electrolyte imbalances and potentially lead to hyponatremia, a dangerous condition caused by an excess of water relative to sodium concentration in the body. Choice B rationale Oral Rehydration Solution (ORS) is specifically formulated to replace the fluids and electrolytes lost during gastroenteritis. It contains a balanced mixture of carbohydrates (glucose) to facilitate sodium and water absorption and essential electrolytes to correct imbalances. This solution prevents dehydration and restores normal physiological function more effectively than other fluids. Choice C rationale Broth contains high levels of sodium, but it lacks other crucial electrolytes like potassium and also does not provide the necessary carbohydrates to promote rehydration. The high sodium content could also contribute to an electrolyte imbalance. It is not an optimal choice for rehydration and is less effective than a balanced ORS. Choice D rationale Seltzer is carbonated water and does not contain the necessary electrolytes or carbohydrates for effective rehydration. The carbonation can also cause abdominal distension and discomfort, which may worsen symptoms of gastroenteritis, such as nausea and bloating. It is not a recommended fluid for rehydrating a child with diarrhea and vomiting. Choice E rationale Diluted apple juice, while containing some sugar, does not have the correct balance of electrolytes needed for rehydration. High sugar concentrations in juices can also have an osmotic effect, drawing water into the intestines and potentially worsening diarrhea. This makes it a less effective choice compared to a specifically formulated oral rehydration solution.
