A 25-year-old primigravida at 32 weeks gestation comes to the prenatal clinic complaining of severe heartburn that occurs daily, especially after meals and when lying down. She states that antacids provide only temporary relief. What is the most important assessment the nurse should perform first?

Severe heartburn in pregnancy is commonly due to hormonal changes and mechanical pressure; dietary assessment is the priority initial evaluation. Preeclampsia assessment is not indicated for isolated heartburn without other symptoms.

Core Nursing Explanation Key Concept Analysis: This question assesses the nurse's ability to prioritize assessments for a common pregnancy complaint: Gastroesophageal reflux disease (GERD) or "heartburn." The core theme is nursing process prioritization and applying non-pharmacological management as the first-line approach for a non-urgent, chronic symptom. The pathophysiology involves progesterone relaxing the lower esophageal sphincter (LES) and the growing uterus increasing intra-abdominal pressure, leading to reflux.

Answer Rationale: Key Point! For a patient presenting with a classic, non-emergent symptom like heartburn, the priority nursing action is to gather data to identify modifiable contributing factors. Assessing dietary habits and meal timing is the most direct, non-invasive, and patient-centered first step. This information is crucial for providing immediate, effective patient education (e.g., avoiding spicy/fatty foods, eating smaller meals, not lying down after eating), which can significantly alleviate symptoms without medication.

Distractor Analysis:
Watch out for confusion! Option ② (Evaluate nausea/vomiting) is incorrect because the patient's chief complaint is specifically heartburn, not nausea/vomiting. While they can co-occur, assessing a different symptom is not the priority for addressing the stated problem.
Option ③ (Check weight gain) is a relevant part of routine prenatal care but is not the first or most important assessment for isolated heartburn. It does not directly inform immediate interventions for reflux.
Option ④ (Assess for preeclampsia) is a critical safety assessment but is not indicated here. Preeclampsia is characterized by hypertension and proteinuria, not isolated heartburn. Jumping to this assessment without supporting symptoms (e.g., headache, visual changes, epigastric pain) is not a priority and could cause unnecessary patient anxiety.

Related Concepts: This question tests the principle of addressing the patient's stated concern first with the least invasive intervention. It reinforces the hierarchy of nursing actions: assess for modifiable factors → educate → then consider pharmacological or further medical evaluation if non-pharmacological measures fail.

Nursing Clinical Practice Guide Clinical Scenario: You are a nurse in a busy prenatal clinic. Maria, a 25-year-old first-time mother at 32 weeks, tells you, "This heartburn is killing me! I take Tums, but it just comes right back, especially at night." She appears comfortable but frustrated.

Nursing Intervention Strategy: 1. Assessment: Start with a focused interview. "Can you describe what you typically eat in a day? How close to bedtime do you have your last meal or snack? Do you notice certain foods make it worse?" This builds rapport and collects actionable data. 2. Planning & Implementation: Based on her answers, provide tailored education. For example: "Try having 5-6 small meals instead of 3 large ones. Avoid citrus, chocolate, caffeine, and fried foods for a few days and see if it helps. Prop yourself up with pillows when you sleep." Document the teaching and her response. 3. Evaluation: At the next visit, ask, "How has the heartburn been since we talked about changing your eating habits?" This evaluates the effectiveness of your intervention.

Patient Safety and Precautions: While antacids like calcium carbonate are generally safe, advise the patient not to overuse them and to inform her provider if symptoms persist despite lifestyle changes, as this may require evaluation for other conditions or prescription medication.

Nursing Procedure & Medication Flow Patient Education for GERD in Pregnancy: 1. Dietary Modifications: Identify and avoid trigger foods (spicy, acidic, fatty). 2. Meal Management: Eat small, frequent meals. Avoid eating within 2-3 hours of lying down. 3. Positioning: Sleep with the head of the bed elevated (use pillows or blocks under the bed frame). 4. Medication Use: If antacids are used, take them as directed (usually 1 hour after meals and at bedtime). Caution against aluminum- or magnesium-based antacids with renal issues.

A Word from Your Senior Nurse "In the clinic or on the floor, patients will bring you a dozen different concerns. Your superpower is knowing where to start. For something like heartburn, jumping straight to checking for preeclampsia is like using a firehose on a candle—it's the wrong tool and can flood the situation with fear. Always start simple. Ask about their day, their habits. Often, the solution is right there in their routine, and your guidance can make an immediate difference. On the NCLEX, they love to test if you know the difference between a 'first action' for a common problem and a 'critical action' for an emergency. Keep your priorities straight!"
