Correct Answer: A

Rationale: The correct answer is to replace lost fluid and sodium. During an acute episode of ulcerative colitis, the priority is to manage the patient's fluid and electrolyte balance. This is crucial due to the potential for dehydration and electrolyte imbalances resulting from diarrhea and inflammation in the colon. Monitoring serum glucose levels (Choice B) may be important for patients on steroid therapy, but in this scenario, fluid and electrolyte balance take precedence. Restricting dietary intake of foods high in potassium (Choice C) is not a priority in the acute phase of ulcerative colitis. While noting changes in stool color and consistency (Choice D) is important for assessing the patient's gastrointestinal status, it is not the priority when managing acute ulcerative colitis.
