The nurse suspects a hiatal hernia. Which assessment finding would be most characteristic of this condition? ## 보기 1. Sharp, stabbing chest pain that worsens with deep breathing 2. Projectile vomiting immediately after eating 3. Heartburn that worsens when lying down **✔ 정답** 4. Severe abdominal pain in the right upper quadrant **정답: 3** ## 해설 Heartburn worsening when lying down is characteristic of hiatal hernia due to increased gastric reflux. Other options are associated with different conditions (pleurisy, pyloric stenosis, cholecystitis). ## 심화 해설 Understanding Hiatal Hernia Pathophysiology A hiatal hernia occurs when a portion of the stomach protrudes through the esophageal hiatus of the diaphragm into the thoracic cavity. This anatomical displacement compromises the function of the lower esophageal sphincter (LES). Normally, the LES, reinforced by the diaphragmatic crura, acts as a high-pressure zone preventing gastric contents from refluxing into the esophagus. When the stomach herniates, the acute angle of His is lost, and the LES pressure decreases, leading to gastroesophageal reflux. Why Heartburn Worsens When Lying Down The most characteristic symptom of a hiatal hernia is heartburn (pyrosis) that intensifies in the supine position. This occurs because gravity no longer assists in retaining gastric contents within the stomach. When the client lies flat, acidic gastric fluid flows freely through the incompetent LES and into the esophagus, causing a retrosternal burning sensation. This positional relationship is a hallmark clinical feature that distinguishes reflux-related chest discomfort from other etiologies. The diagnostic study by Jiang et al. supports the clinical focus on dynamic assessment, noting that maneuvers such as the Valsalva maneuver—which increases intra-abdominal pressure—are used during imaging to provoke herniation and reflux, mirroring the symptom exacerbation seen when clients lie down or strain [1]. Analysis of Incorrect Options - **Option 1:** Sharp, stabbing chest pain that worsens with deep breathing is characteristic of pleuritic chest pain, suggesting pericarditis or a pulmonary embolism, not a hiatal hernia. Hiatal hernia pain is typically a burning sensation, not sharp and stabbing, and is not related to the respiratory cycle. - **Option 2:** Projectile vomiting immediately after eating is a classic sign of pyloric stenosis, an obstruction at the gastric outlet. While a large paraesophageal hernia can cause dysphagia or a sensation of fullness, projectile vomiting is not the most characteristic finding. - **Option 4:** Severe abdominal pain in the right upper quadrant is the hallmark of acute cholecystitis or biliary pathology. Hiatal hernia discomfort is typically substernal, not localized to the right upper quadrant. Clinical Assessment and Diagnostic Correlation The nurse's clinical assessment directly parallels the diagnostic principles used in advanced imaging. Just as gastric contrast ultrasound assesses for reflux and herniation during dynamic maneuvers like the Valsalva maneuver, the nurse elicits a history of positional symptom changes [1]. Asking the client if symptoms worsen when lying flat, bending over, or straining helps clinically confirm the suspicion of a hiatal hernia and associated gastroesophageal reflux disease (GERD). This symptom pattern reflects the mechanical failure of the anti-reflux barrier, which is the core pathophysiological defect in this condition.

This occurs because gravity no longer helps retain gastric contents, allowing acid to reflux through the incompetent lower esophageal sphincter (LES). When assessing a client with suspected hiatal hernia, always inquire about the timing and triggers of their chest pain. A clear history of positional reflux (worse when lying down, bending over, or straining) is a hallmark clinical clue that helps differentiate it from cardiac or pleuritic pain. CautionDo not dismiss chest pain as reflux without a thorough assessment. Always rule out cardiac ischemia first, as a myocardial infarction can present with similar epigastric or burning sensations. An ECG and troponin level are often indicated before assuming a gastrointestinal etiology. ## 핵심 개념 - **Hiatal Hernia** — Protrusion of the stomach through the esophageal hiatus of the diaphragm into the thoracic cavity, often compromising the lower esophageal sphincter. - **Lower Esophageal Sphincter** — A ring of smooth muscle at the gastroesophageal junction that prevents reflux of gastric contents; its incompetence is central to GERD and hiatal hernia symptoms. - **Heartburn** — A retrosternal burning sensation caused by the reflux of acidic gastric contents into the esophagus, classically exacerbated by recumbency. ## 같은 주제 문제 - [The nurse is evaluating a 65-year-old client with suspected hiatal hernia who reports disc…](https://mymerci.kr/pages/nclex_q.php?qn_id=540536) - [A nurse is teaching a client with hiatal hernia about dietary modifications.
