A nurse is reinforcing teaching to a client about the risk factors for GERD (gastroesophageal reflux disease). Which of the following statements should the nurse include?

Brief Introduction: Gastroesophageal reflux disease occurs when the lower esophageal sphincter fails to maintain adequate pressure, allowing gastric acid to reflux into the esophagus. Chronic exposure to low pH levels leads to Barrett’s esophagus or erosive esophagitis, characterized by substernal pyrosis and regurgitation. Rationale: A. Mercury exposure is primarily a neurotoxic concern associated with certain predatory fish and does not influence the pathophysiology of acid reflux. GERD dietary restrictions focus on substances that decrease sphincter tone or increase gastric acid production, rather than heavy metal content in seafood. B. Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) can exacerbate GERD by inhibiting prostaglandin synthesis, which weakens the protective gastric mucosal barrier. This increases the risk of peptic ulceration and esophageal irritation, making these medications potentially harmful for clients with chronic reflux. C. Postprandial recumbency eliminates the benefit of gravitational forces in keeping gastric contents within the stomach. Lying down within 3 hours of eating significantly increases intra-abdominal pressure against the sphincter, facilitating the retrograde flow of acid into the distal esophagus. D. Alcohol and caffeine act as pharmacological triggers that cause smooth muscle relaxation of the lower esophageal sphincter. Reducing these substances prevents the involuntary opening of the sphincter and limits the gastric acid secretion that leads to painful mucosal inflammation and cough.
