A nurse is reinforcing teaching about dietary recommendations for a client who has a hiatal hernia. Which of the following client statements indicate understanding of the teaching? (Select all that apply.)

A. "I will sleep with the head of my bed elevated." Elevating the head of the bed helps reduce reflux symptoms, which are common in hiatal hernia. B. "I will lie down for one half hour after meals." Clients should avoid lying down after meals; this worsens reflux. C. "I will drink less fluid." Adequate hydration is important. Fluid restriction is not indicated unless there's another comorbidity (e.g., heart failure). D. "I will try not to gain weight." Obesity increases intra-abdominal pressure, worsening hiatal hernia symptoms. E. "I will consume less caffeine and spicy foods." Caffeine and spicy foods can trigger reflux, so they should be avoided or limited.
