An older client's colonoscopy reveals the presence of extensive diverticulosis. what type of diet should the nurse encourage the client to follow?

The nurse should encourage the patient to adopt a high fiber diet.

Explanation:

Diverticulosis, or diverticular disease, is a disease of the intestines characterized by the formation of diverticula, which are small pockets, in the intestinal mucosa. Diverticula form when points in the bowel wall are fragile and are projected outwards due to intestinal contractions.

The treatment for diverticulosis is mainly made with a diet rich in fiber, present in fruits and vegetables. Fiber-rich dietary supplements, such as Metamucil, may also be helpful in improving bowel function. For this reason, we can say that the nurse in the case shown in the above question is likely to indicate a high fiber diet for the patient.
