A patient presents with severe abdominal pain, vomiting, and distension, suspected of having a large bowel obstruction. Which nursing intervention is most appropriate to prioritize?

Rationale: A. Administer a laxative to relieve constipation is incorrect because laxatives are contraindicated in bowel obstruction. They can worsen distension, increase pain, and risk perforation. B. Insert a nasogastric tube to decompress the bowel is correct because a nasogastric (NG) tube relieves pressure from accumulated fluids and gas, reduces vomiting, prevents aspiration, and stabilizes the patient before further interventions, including surgery. Decompression is a priority in acute bowel obstruction to manage symptoms and prevent complications. C. Encourage oral intake to maintain hydration is incorrect because oral intake is contraindicated in acute bowel obstruction due to the risk of worsening distension and vomiting. Hydration should be maintained intravenously. D. Prepare the patient for surgical intervention is important, especially if the obstruction is complete or ischemic, but initial stabilization with bowel decompression takes priority before surgery.
