Final answer:
For managing IBS, the nurse should advise identifying and avoiding trigger foods, increase fiber intake, stay hydrated, and regularly exercise. Avoiding high-fiber diets, limiting fluid intake, and eating large, irregular meals are not recommended for IBS management.
Step-by-step explanation:
When providing guidance for managing Irritable Bowel Syndrome (IBS), it is important to focus on dietary and lifestyle changes that can help manage symptoms. One key aspect of this is to identify and avoid trigger foods that may exacerbate IBS symptoms. Contrary to avoiding a high-fiber diet, patients are generally advised to increase their fiber intake, particularly soluble fiber, which can help with both diarrhea and constipation - common symptoms of IBS. Enzymes that digest cellulose add bulk to food, easing bowel movements, so a balanced diet high in fiber can be beneficial.
Furthermore, staying hydrated by drinking plenty of water is crucial, as well as engaging in regular exercise, which helps to stimulate normal bowel movements. Patients should also avoid large, irregular meals, as smaller, regular meals help to decrease the burden on the digestive system. Instead of limiting fluid intake, it's recommended to ensure adequate hydration to assist with digestion and bowel function.
