A nurse is reinforcing teaching about ileostomy care with a client. The nurse should recognize which of the following statements by the client indicates a need for further teaching?

A. Apples are a good source of fiber, with about 4.4 grams of fiber in a medium-sized apple with the skin. Apples contain soluble and insoluble fiber, which can aid in digestion and help prevent constipation. This is a suitable choice for a high-fiber snack.
B. Almonds are nutritious and provide fiber, but they are not as high in fiber compared to other options like fruits, vegetables, and whole grains. One ounce of almonds contains about 3.5 grams of fiber. While almonds are beneficial, they are not typically the primary choice for increasing fiber intake to alleviate constipation.
C. Bran cereals are often recommended for their high fiber content. Half a cup of bran cereal can provide around 10 grams of fiber or more, depending on the brand and type. Bran cereals are particularly rich in insoluble fiber, which adds bulk to stool and helps promote regular bowel movements. This is an excellent choice for increasing fiber intake to manage constipation.
D. Sweet potatoes are nutritious and contain dietary fiber, with about 3.8 grams of fiber in half a cup of cooked sweet potatoes. While they contribute to fiber intake, they generally do not provide as much fiber compared to options like whole grains or bran cereals.

A. There is no indication of an emergency based on black stools alone without other concerning symptoms such as severe abdominal pain, cramping, or signs of gastrointestinal bleeding.
B. While gathering more information about the client's diet may be helpful in some cases, it does not address the specific concern about the black stools related to iron supplementation.
C. Unless there are other concerning symptoms, such as gastrointestinal bleeding or significant discomfort, this situation does not typically warrant an immediate visit to the office. It can be managed with reassurance and education over the phone.
D. Iron supplements commonly cause stools to turn black due to the way iron is metabolized in the digestive system. This change in stool color is known as "iron-induced blackening." It occurs because iron supplements contain iron salts that undergo chemical reactions in the gastrointestinal tract, resulting in the production of iron sulfide compounds that impart a black color to the stool.
