What is a likely finding in the nurse's assessment of a patient who has a large bowel obstruction?

Rationale: A. Vomiting is more common in small bowel obstruction and is usually less severe in large bowel obstruction. B. A large bowel obstruction causes accumulation of gas and fecal material proximal to the blockage, leading to significant abdominal distention. C. Large bowel obstruction may eventually cause metabolic acidosis due to impaired perfusion and tissue hypoxia, not alkalosis. D. Back pain is not a typical sign of large bowel obstruction; the primary symptom is abdominal discomfort, distention, and constipation.
