Rationale: In this scenario, observing puffy eyes in a child being treated with oral rehydration solution may indicate fluid overload. Continuing to give ORS but more slowly is the correct course of action as it helps manage hydration without overloading fluids. Choice B is not the best option in this situation as the issue is not about the quantity of the solution, but the rate of administration. Choice C is incorrect because plain water or milk is not a suitable alternative for rehydration in cases of dehydration. Choice D is also incorrect as reassessing the patient does not directly address the issue of puffy eyes, which suggests a need to adjust the administration of ORS.
