A nurse is caring for a client who reports abdominal pain. The nurse is caring for a client who has abdominal pain. Which of the following actions should the nurse take? Select all that apply.

A. Administer an enema to promote bowel evacuation: Enemas increase intraluminal pressure and can worsen inflammation or risk perforation in acute diverticulitis. The bowel should be rested during the acute phase to reduce irritation and allow healing. Using an enema can aggravate symptoms and is contraindicated. B. Prepare to insert a nasogastric tube: The client has nausea, vomiting, abdominal distention, and worsening pain, which can indicate possible ileus or obstruction associated with acute diverticulitis. An NG tube may be needed to decompress the stomach and prevent further vomiting. Preparing for NG tube insertion supports symptom management and prevents complications. C. Ensure the client is on bed rest: Bed rest decreases bowel activity and reduces discomfort during acute diverticulitis episodes. It helps limit movement that can exacerbate abdominal pain and reduces metabolic demands while the inflammation is being treated. D. Administer a laxative to prevent constipation: Laxatives stimulate bowel motility, which increases pressure within the colon and can worsen inflammation or risk perforation in acute diverticulitis. These medications are avoided during the acute phase to prevent exacerbation of symptoms or complications. E. Provide the client with foods that are high in fiber: High-fiber foods help prevent future diverticulitis episodes but are not appropriate during an acute flare. Fiber increases bowel workload and irritation, worsening pain and inflammation. Dietary fiber is introduced only after acute symptoms have resolved. F. Ensure client is NPO: Keeping the client NPO rests the bowel and reduces stimulation during acute inflammation. NPO status also prepares the client for potential procedures and reduces the risk of worsening symptoms from food intake. This is standard treatment during acute diverticulitis until symptoms improve. G. Position client in high-Fowler's position: High-Fowler’s position is more useful for clients with respiratory compromise rather than abdominal inflammation. Although sitting upright may provide minor comfort, it does not specifically support management of acute diverticulitis. Supine or semi-Fowler's positions are better tolerated to reduce abdominal strain.
