A nurse is providing teaching to a client who is at 8 weeks of gestation and experiencing episodes of nausea and vomiting. Which of the following instructions should the nurse include?

A. Brush teeth immediately after eating: Brushing teeth right after eating may worsen nausea and vomiting due to stimulation of the gag reflex or irritation of the oral mucosa. It is better to rinse the mouth with water or a mild mouthwash instead. B. Lay down for 30 min after meals: Lying down after eating can exacerbate nausea and increase the risk of reflux. Remaining upright after meals promotes gastric emptying and reduces symptoms of morning sickness. C. Drink 12 oz of water with each meal: Drinking large amounts of fluid during meals can distend the stomach and worsen nausea. Small, frequent sips of fluids between meals are more effective in maintaining hydration without increasing discomfort. D. Eat a dry carbohydrate before getting out of bed: Consuming a dry carbohydrate, such as toast or crackers, before rising in the morning helps stabilize blood sugar levels and reduce nausea associated with morning sickness. This is a safe and effective strategy for managing early pregnancy nausea.
