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?

Choice A reason: Dietary iron restrictions are not typically recommended for clients with ulcerative colitis. In fact, iron supplementation may be necessary due to chronic blood loss. This choice does not reflect a pathophysiological cause of anemia in colitis. Choice B reason: Intestinal parasites are not a common complication of ulcerative colitis. While they can cause anemia in other contexts, they are not typically associated with inflammatory bowel disease in developed healthcare settings. Choice C reason: Chronic blood loss from ulcerated and inflamed intestinal mucosa is a major contributor to anemia in ulcerative colitis. Repeated episodes of bleeding during flares lead to iron deficiency and reduced hemoglobin levels, necessitating monitoring and treatment. Choice D reason: While malabsorption can occur in other gastrointestinal disorders like celiac disease or Crohn’s disease, ulcerative colitis primarily affects the colon, which is not a major site of nutrient absorption. Therefore, this is not a primary cause of anemia in UC.
