Mr. Novello is an 81-year old male patient who presents with crampy abdominal pain in the hypogastrum and a vague history as to his last normal bowel movement. Physical examination reveals distention and high-pitched bowel sounds. The patient says he has never has this kind of problem before and denies any history of abdominal surgery. Abdominal radiographs reveal a frame pattern of colonic distention. The AGACNP considers
Correct Answer: C
Rationale: The correct answer is C: Decompression of the colon with rectal tube. This is the most appropriate intervention for a patient with acute colonic pseudo-obstruction (ACPO), also known as Ogilvie's syndrome. In this condition, there is colonic distention without an actual mechanical obstruction, leading to symptoms like abdominal pain, distention, and high-pitched bowel sounds. Decompression with a rectal tube can help relieve the distention and prevent complications like perforation.
Choice A (stimulant laxative) is incorrect because ACPO is not due to simple constipation, so laxatives would not be effective. Choice B (carcinoma of the bowel) is unlikely given the acute onset and lack of risk factors. Choice D (angiography for mesenteric ischemia) is not indicated in this case as there are no signs of acute ischemia.
In summary, the correct choice is C because it directly addresses the underlying issue of colonic distention in
