The nurse is contributing to a patient's teaching plan on how to avoid dumping syndrome after a gastrectomy. Which of the following would be included in the teaching?

A. Decreasing high fiber complex carbohydrates: High-fiber foods slow gastric emptying, which is beneficial. Only simple sugars should be reduced. B. Avoid fluids with meals: Fluids with meals can cause rapid stomach emptying, triggering dumping syndrome. Fluids should be taken 30-60 minutes before or after meals. C. Increase activity after eating: Activity after meals can worsen symptoms by accelerating digestion. D. Eat heavy meals to delay emptying: Large meals worsen dumping syndrome. The patient should eat small, frequent meals.
