A pregnant client at 28 weeks gestation reports experiencing frequent heartburn and asks the nurse for advice on managing this discomfort. Which intervention should the nurse recommend?
A 28-year-old primigravida at 28 weeks gestation reports severe heartburn after meals and when lying down, affecting sleep and eating. Vital signs are stable, and fetal heart tones are 140 bpm.
1Take an over-the-counter antacid containing aluminum hydroxide before each meal
2Drink a large glass of milk immediately after eating to neutralize stomach acid
3Lie down flat for 30 minutes after meals to promote digestion
4Eat small, frequent meals and avoid lying down for 2-3 hours after eating✓ 정답
해설
Heartburn in pregnancy is caused by hormonal relaxation of the lower esophageal sphincter and uterine pressure. Eating small, frequent meals and avoiding lying down after eating helps prevent reflux. Antacids or large milk intake are less recommended initial interventions.
Understanding the Physiology
During pregnancy, elevated progesterone levels cause relaxation of smooth muscle, including the lower esophageal sphincter (LES). This, combined with the mechanical pressure from the enlarging uterus pushing upward on the stomach, leads to gastroesophageal reflux, manifesting as heartburn. The discomfort is often exacerbated postprandially and in the supine position because these conditions increase intra-gastric pressure and reduce the gravitational advantage that normally keeps stomach contents down.
Analysis of the Correct Answer
The recommendation to eat small, frequent meals and avoid lying down for 2-3 hours after eating (Option 4) directly addresses the underlying mechanisms of pregnancy-related heartburn without introducing pharmacological agents. Small, frequent meals prevent gastric over-distension, a primary trigger for transient LES relaxations. Maintaining an upright posture for 2-3 hours postprandially utilizes gravity to reduce reflux and facilitates gastric emptying, which is already delayed by progesterone. This non-pharmacological approach is the foundational, first-line lifestyle modification for managing this minor ailment of pregnancy [1].
Critique of Incorrect Options
- Option 1: While aluminum hydroxide antacids are sometimes used, recommending them "before each meal" is not a standard first-line or prophylactic strategy. The initial management, as supported by antenatal education, focuses on dietary and positional habits rather than routine pre-meal medication for a minor ailment [1].
- Option 2: Drinking a large glass of milk immediately after eating increases gastric volume and distension, which can paradoxically worsen reflux. Furthermore, the calcium and protein in milk can stimulate gastrin secretion, which increases acid production after an initial buffering effect, leading to rebound hyperacidity.
- Option 3: Lying down flat after meals is contraindicated. This position negates the effect of gravity, facilitating the passive reflux of acidic gastric contents into the esophagus and significantly worsening heartburn symptoms. This advice would exacerbate the client's reported discomfort when lying down.
Integration into Antenatal Care
Educating primigravidae on the management of minor ailments is a core nursing intervention. A structured antenatal class significantly improves a woman's knowledge and ability to self-manage discomforts like heartburn [1]. The nurse's role is to empower the client with practical, evidence-informed self-care strategies. For this client, explaining that her symptoms are a normal, albeit uncomfortable, consequence of physiological changes, and that simple behavioral modifications—like altering meal patterns and post-meal positioning—are highly effective, constitutes essential and immediate nursing care.

Clinical Practice Guidance
Non-Pharmacological First-Line Management
For a pregnant client at 28 weeks gestation reporting frequent heartburn, the primary intervention is lifestyle modification. Instruct the client to consume small, frequent meals throughout the day to prevent gastric over-distension, which is a primary trigger for transient lower esophageal sphincter relaxations. Emphasize the critical importance of maintaining an upright posture, sitting or standing, for at least 2 to 3 hours after eating. This uses gravity to reduce reflux and aids gastric emptying, which is physiologically delayed by progesterone. Advise against lying down flat immediately after meals and recommend elevating the head of the bed on blocks if nighttime symptoms persist.
Dietary and Behavioral Counseling
Provide specific dietary guidance. Advise the client to identify and avoid trigger foods that can decrease LES pressure, including fatty or fried foods, chocolate, caffeine, and spicy or acidic items. Discourage the practice of drinking large volumes of fluid, including milk, with meals, as this can increase gastric volume and cause acid rebound. Recommend consuming liquids between meals instead. Chewing gum or sucking on hard candy can stimulate saliva production, which may help neutralize esophageal acid.
Pharmacological Considerations
If lifestyle and dietary modifications provide insufficient relief, a step-wise pharmacological approach may be considered in collaboration with the healthcare provider. Over-the-counter antacids containing calcium carbonate or aluminum hydroxide are generally considered safe for occasional, short-term use during pregnancy but are not a first-line prophylactic strategy. Their use should be spaced appropriately from iron supplements, as they can interfere with absorption. Persistent or severe symptoms refractory to these measures warrant further evaluation to rule out complications such as esophagitis.
Lower Esophageal Sphincter (LES) — A ring of smooth muscle at the stomach entrance that relaxes during pregnancy due to progesterone, allowing gastric acid to reflux into the esophagus.
Gastric Over-distension — Excessive stretching of the stomach from large meals, which triggers transient LES relaxations and promotes reflux.
Progesterone Effect — The hormone that maintains pregnancy also relaxes smooth muscle throughout the body, including the gastrointestinal tract, slowing gastric emptying and relaxing the LES.
Postprandial — The period immediately after eating a meal, during which heartburn symptoms are often most severe.
Gravitational Advantage — The benefit of an upright posture that uses gravity to help keep stomach contents from flowing backward into the esophagus.
