Situation: A 46-year-old woman has had heartburn and regurgitation after meals for 6 months. Her body mass index (BMI) is 29 kg/m², and she smokes. Upper endoscopy shows erosive esophagitis and a small sliding hiatal hernia. She takes no other medicines. After teaching about lifestyle measures for her reflux, which statement shows a need for **FURTHER** teaching?

The head of the bed is raised about 15 to 20 cm (6 to 8 in) with blocks or a wedge so the whole upper body is inclined. Extra pillows only bend the body at the waist, which raises abdominal pressure and can worsen reflux. Avoiding lying down for 2 to 3 hours after eating, weight loss, and stopping smoking are correct measures.

Why extra pillows are wrong
The goal of positional therapy in gastroesophageal reflux disease is to keep the gastroesophageal junction above the level of gastric contents while the person lies flat. Raising the head of the bed by 15 to 20 cm (6 to 8 in) with blocks or a wedge tilts the entire upper body, so gravity helps keep acid in the stomach. In contrast, sleeping with two extra pillows only flexes the neck and bends the trunk at the waist. That position increases intra-abdominal pressure, which can push gastric contents upward and actually worsen reflux. Watch out! Pillows under the head are not a substitute for elevating the head of the bed; they create an angle at the waist rather than a straight incline of the whole torso.

Why the other statements are correct
The patient’s BMI of 29 kg/m² places her in the overweight range, and smoking reduces lower esophageal sphincter tone. Weight loss and smoking cessation are both evidence-based lifestyle measures for reducing reflux symptoms ^[1]. Avoiding lying down for 2 to 3 hours after a meal is also appropriate because the upright posture allows gravity to assist gastric emptying and limits acid exposure to the esophagus while the stomach is full ^[2]. Education about these lifestyle habits improves patients’ knowledge and symptom management ^[3].

Clinical reasoning for the licensure exam
When a question asks which statement shows a need for further teaching, the incorrect statement is the one that reflects a common misconception. Many patients believe that adding pillows is equivalent to raising the head of the bed, but only a whole-body incline achieved with blocks or a wedge is effective. The presence of a sliding hiatal hernia and erosive esophagitis makes positional therapy especially important, because both conditions increase the risk of acid exposure when intra-abdominal pressure rises. Key point! For reflux, elevate the bed frame or use a wedge under the mattress, not extra pillows under the head.
