The nurse reviews discharge instructions with a client who has gastroesophageal reflux disease (GERD). Which instruction is most important for the nurse to emphasize?

Rationale: A. Minimize intake of spicy foods: Reducing spicy food intake can help decrease GERD symptoms, but it is a lifestyle modification that supports symptom management rather than preventing complications. B. Avoid wearing tight fitting clothes: Tight clothing can increase intra-abdominal pressure and worsen reflux, but this measure alone is not the most critical for preventing acid exposure or esophageal damage. C. Begin a smoking cessation program: Smoking can worsen GERD by decreasing lower esophageal sphincter tone. While cessation is important for overall health and symptom control, immediate reflux prevention strategies take priority for symptom relief. D. Remain upright following meals: Maintaining an upright position for at least 30 to 60 minutes after eating helps prevent reflux of gastric contents into the esophagus, reducing the risk of esophagitis and severe symptoms.
