The nurse is caring for a client with diverticulosis who reports difficulty getting enough dietary fiber. What should the physician likely prescribe?

In the context of managing diverticulosis, the correct choice is to prescribe psyllium, which is a soluble fiber supplement. Psyllium works by adding bulk to stool and promoting regular bowel movements, which is important for individuals with diverticulosis. A high-fiber diet can help prevent complications, such as diverticulitis, by minimizing straining during defecation and promoting a healthy digestive system.

Clients with diverticulosis often experience challenges in obtaining enough dietary fiber from their food intake alone due to dietary restrictions or personal preferences. Therefore, incorporating a fiber supplement like psyllium can be an effective strategy to help these clients meet their fiber needs.

The other options listed do not address the underlying issue of fiber deficiency in a way that aligns with diverticulosis management. Oil-retention enemas are typically used for constipation relief but do not contribute to long-term fiber intake. Codeine is an opioid analgesic that can lead to constipation, which would be counterproductive for a client needing fiber. Bisacodyl is a stimulant laxative that may not address the need for bulk-forming fiber and could also lead to potential bowel irritability. Thus, psyllium becomes the most appropriate option to aid the client in achieving adequate fiber intake
