A nurse is reinforcing teaching with a client who has gastroesophageal reflux (GERD). Which of the following statements by the client indicates an understanding of the teaching?

A. "I will increase vitamin C intake by drinking orange juice.": Citrus foods are acidic and can worsen GERD symptoms by increasing esophageal irritation and reflux. Clients should avoid or limit acidic foods to reduce discomfort. B. "I will sleep flat on my back at night.": Lying flat can promote reflux of stomach contents into the esophagus, worsening GERD symptoms. Elevating the head of the bed or sleeping on the left side is recommended. C. "I will lie down for 30 minutes after each meal.": Lying down after eating increases the likelihood of acid reflux. Clients should remain upright for at least 2–3 hours post-meal to reduce symptoms. D. "I will eat six small meals each day.": Eating smaller, more frequent meals helps prevent excessive gastric distention and reduces reflux episodes. This approach is an effective strategy for managing GERD.
