A nurse is teaching a client who has a history of ulcerative colitis and a new diagnosis of anemia. Which of the following manifestations of colitis should the nurse identify as a contributing factor to the development of the anemia?

A. Chronic blood loss is a common complication of ulcerative colitis due to inflammation and ulceration of the intestinal mucosa, which can cause rectal bleeding. Persistent blood loss leads to iron deficiency anemia because iron stores become depleted as the body continually replaces lost red blood cells. This is the most likely cause of anemia in clients with ulcerative colitis. B. Clients with ulcerative colitis are not typically advised to restrict dietary iron. In fact, they are often encouraged to consume iron-rich foods or take supplements if anemia develops. Therefore, dietary restrictions are not a contributing factor. C. Intestinal malabsorption is more commonly associated with conditions like celiac disease or Crohn’s disease, where the small intestine is affected. Ulcerative colitis primarily involves the colon, which is not a major site for nutrient absorption, so malabsorption is unlikely to cause anemia in this case. D. Intestinal parasites can cause anemia through blood loss or nutrient competition, but they are not characteristic of ulcerative colitis. Their presence would indicate a separate condition, not a manifestation of colitis.
