Final answer:
A 29-year-old woman with a history of ulcerative colitis presenting with abdominal pain and signs of a colonic perforation should be managed with broad-spectrum antibiotics, NPO status, IV fluids, and rapid surgical consultation.
Step-by-step explanation:
The question concerns a 29-year-old woman with a history of ulcerative colitis who presents to the emergency department with fever, tachycardia, abdominal distension, and severe pain. An upright chest X-ray reveals the presence of air within the wall of the colon, which is indicative of a possible perforation. Immediate management should include the administration of broad-spectrum antibiotics to cover both gram-positive and gram-negative organisms, as well as anaerobes. The patient should be kept nil per os (NPO), provided with intravenous fluids, and a surgical consultation should be promptly obtained, given the severity of the findings and the potential need for surgical intervention to address the perforation.
