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.

Restricting dietary intake of foods high in potassium (Choice C) is not a priority in the acute phase of ulcerative colitis.
