Which instruction should be included in the teaching plan of a client diagnosed with a peptic ulcer?

Peptic ulcer management requires a balance between neutralizing gastric acidity and avoiding stimuli that trigger hypersecretion. Dietary interventions aim to minimize gastric distention and reduce the exposure of the raw mucosal lesion to corrosive hydrochloric acid. Patient education focuses on behavioral modifications that support the pharmacological effects of proton pump inhibitors. A. Eat small meals throughout the day: Frequent, small feedings prevent the excessive gastric distention that triggers a large release of gastrin and acid. This approach keeps the stomach from becoming too empty or too full, maintaining a more stable pH. It reduces the mechanical and chemical stress on the ulcer. B. Drink alcohol and caffeine in moderation: Alcohol directly irritates the gastric mucosa and caffeine stimulates parietal cells to produce more acid. Both substances delay the healing process and should be strictly avoided during the acute phase of the disease. Moderation is often insufficient for active ulcer resolution. C. Reintroduce irritating foods in small amounts: Foods that cause discomfort, such as spicy dishes or highly acidic fruits, should be eliminated until complete healing is confirmed. Reintroducing these items prematurely can provoke symptomatic flares and exacerbate mucosal inflammation. The diet should remain bland during treatment. D. Restrict fluid to 1000 mL per day: There is no physiological rationale for fluid restriction in peptic ulcer disease; in fact, adequate hydration is necessary for overall mucosal health. Restricting fluids can lead to constipation and does not influence the rate of gastric acid production. Standard fluid intake is encouraged.
