Which client statement indicates a need for further teaching about managing gastroesophageal reflux disease (GERD)?

The statement indicating a need for further teaching about managing gastroesophageal reflux disease (GERD) is the plan to have a snack one hour before going to bed. In GERD management, it's important to avoid eating close to bedtime because lying down shortly after eating can increase the likelihood of acid reflux, as the angle of the esophagus in relation to the stomach makes it easier for gastric contents to flow back into the esophagus.

Encouraging a longer duration between the last meal and lying down helps reduce the risk of experiencing symptoms. Other strategies might involve dietary modifications and positioning during sleep, such as elevating the head of the bed or sleeping on the left side, as these approaches can help minimize nighttime reflux.

The other statements reflect appropriate understanding and strategies for managing GERD, such as eating smaller meals throughout the day and reducing or eliminating alcohol consumption, which can trigger reflux symptoms.
