A nurse teaches a client who is at risk for colorectal cancer. Which dietary recommendation would the nurse include?

Choice A reason: Low-fiber and low-residual foods are typically recommended for patients during acute flares of inflammatory bowel disease to rest the bowel. However, for cancer prevention, these foods are contraindicated because they increase transit time and the duration that potential carcinogens remain in contact with the intestinal lining.

Choice B reason: Cruciferous vegetables like broccoli and cauliflower are high in fiber and contains chemopreventive compounds. High fiber intake increases stool bulk and decreases transit time, which dilutes potential carcinogens and reduces their contact with the colonic mucosa, significantly lowering the long-term risk of developing colorectal adenocarcinoma.

Choice C reason: Diets high in animal fats are strongly associated with an increased risk of colorectal cancer. High fat intake increases the secretion of bile acids into the gut, which can be converted by intestinal bacteria into secondary bile acids that act as promoters of cellular mutation and malignancy.

Choice D reason: While white rice and bread are refined carbohydrates that are easy to digest, they lack the essential fiber necessary for colorectal health. A diet heavy in refined grains is associated with higher glycemic loads and increased cancer risk, whereas whole grains are preferred for their protective fibrous qualities.

Choice A reason: Standard maintenance hemodialysis is typically not performed daily in a clinical setting. While some home hemodialysis programs offer more frequent, shorter sessions, the conventional schedule for the vast majority of patients in outpatient centers involves three sessions per week. Daily dialysis is usually reserved for acute, unstable patients in intensive care units.

Choice B reason: The description of a catheter inserted into the abdomen refers to peritoneal dialysis, not hemodialysis. Hemodialysis requires vascular access, such as an arteriovenous fistula, graft, or a central venous catheter in the chest or neck. Peritoneal dialysis uses the peritoneal membrane as the filter, whereas hemodialysis uses an external artificial kidney machine.

Choice C reason: In the United States and most clinical protocols, the standard frequency for outpatient hemodialysis is three times per week, with each session lasting approximately 3 to 5 hours. This schedule is designed to sufficiently remove metabolic waste products and excess fluid that accumulate when the kidneys have reached end-stage failure.

Choice D reason: End-stage renal disease (ESRD) is characterized by permanent, irreversible kidney damage. Unlike acute kidney injury, where the kidneys may eventually heal and resume function, ESRD requires lifelong renal replacement therapy (dialysis) or a kidney transplant. Teaching the client that the kidneys will "heal" provides false hope and inaccurate medical information.
