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. While a diet low in iron can contribute to anemia, clients with ulcerative colitis typically do not have strict dietary iron restrictions; therefore, this is less likely to be the primary cause. B. Malabsorption can cause anemia in conditions like celiac disease, but ulcerative colitis primarily affects the colon, which is not the main site of iron absorption. Thus, malabsorption is less significant in this context. C. Ulcerative colitis often causes recurrent bleeding from inflamed colon mucosa, leading to iron-deficiency anemia over time. Chronic gastrointestinal blood loss is the most common contributing factor for anemia in ulcerative colitis. D. Parasitic infections can cause anemia due to blood loss, but in a client with ulcerative colitis, parasites are not the typical cause.
