A 35-year-old male client presents at the emergency department with symptoms of a small bowel obstruction. In collaboration with the primary provider, what intervention should the nurse prioritize?

Choice A reason: In a small bowel obstruction, gastric and intestinal contents accumulate proximal to the obstruction, leading to severe distension, vomiting, and risk of aspiration. A nasogastric tube is a priority intervention for decompression of the stomach, which relieves pain, prevents further vomiting, and reduces the pressure within the intestinal lumen. Choice B reason: While a central venous catheter may eventually be needed if the patient requires total parenteral nutrition (TPN) due to a prolonged obstruction, it is not an immediate priority intervention in the emergency department. Peripheral IV access for fluid resuscitation is sufficient during the initial stabilization phase. Choice C reason: Enemas are generally ineffective for a "small" bowel obstruction, as the blockage is located high in the intestinal tract. Furthermore, introducing fluid or oil into the rectum will not relieve the proximal distension and could cause unnecessary discomfort without addressing the primary pathophysiology of the upper obstruction. Choice D reason: Laxatives and suppositories are contraindicated in a suspected mechanical bowel obstruction. Stimulating peristalsis against a physical blockage can increase intraluminal pressure, worsen abdominal pain, and significantly increase the risk of bowel perforation. Management focus must be on decompression (NG tube) and keeping the patient NPO.
