A nurse is teaching a client who has a new diagnosis of gastroesophageal reflux disease. Which of the following instructions should the nurse include?

Rationale: A. "Lie down after meals.": Lying down after eating increases the risk of gastric contents refluxing into the esophagus due to gravity. Clients with GERD should remain upright for at least 2 to 3 hours after meals to minimize symptoms. B. "Elevate the head of the bed while sleeping.": Elevating the head of the bed by 6 to 8 inches helps prevent nighttime reflux by using gravity to reduce backward flow of stomach acid into the esophagus, which is a key strategy in GERD management. C. "Eat a snack 1 hour before going to bed.": Eating close to bedtime can exacerbate GERD symptoms by increasing gastric volume and acid production, especially when the client lies down soon after eating. A longer gap between the last meal and sleep is advised. D. "Eat three large meals each day.": Large meals increase gastric pressure and acid production, worsening reflux symptoms. Clients with GERD should eat smaller, more frequent meals to reduce gastric distension and minimize acid reflux episodes.
