A nurse is providing nutritional teaching to a client who is experiencing severe nausea due to gastroenteritis. Which of the following responses by the client indicates an understanding of the teaching?

A. "I should lie down after my meals.": Lying down immediately after eating can worsen nausea and increase the risk of acid reflux. Clients should remain upright after meals to facilitate digestion and reduce nausea. B. "I should avoid eating hot foods.": Avoiding hot, spicy, or strong-smelling foods can help reduce nausea and gastrointestinal discomfort. Eating bland, cool, or room-temperature foods is easier on the stomach and aligns with dietary recommendations for gastroenteritis. C. "I should drink a caffeinated beverage one hour before a meal.": Caffeine can irritate the gastrointestinal tract and worsen nausea. Clients should avoid caffeinated beverages during episodes of gastroenteritis to prevent exacerbation of symptoms. D. "I should increase my intake of liquids with meals.": Drinking large amounts of liquid with meals can contribute to feelings of fullness, bloating, and nausea. It is generally recommended to sip fluids between meals rather than during meals to maintain hydration without worsening symptoms.
