For constipation the nurse should suggest a fluid intake of at least 2L per day. The nurse should also offer prune or apple juice because they promote elimination. The nurse should encourage the patient to eat regular meals. Dieting or fasting can decrease stool volume and slow elimination. The nurse should instruct the patient to keep a record of food intake in case of diarrhea because this helps identify specific foods that irritate the GI tract.
