A nurse is reinforcing teaching with a client who is to begin taking lansoprazole. Which of the following statements by the client indicates an understanding of the teaching?

A. "I should report episodes of diarrhea.": Lansoprazole can increase the risk of gastrointestinal infections because reduced stomach acid allows harmful bacteria to survive. Persistent diarrhea may signal C. difficile infection, which requires prompt evaluation. Reporting this symptom helps prevent complications and ensures timely treatment. B. "I should expect the medication to cause indigestion.": Lansoprazole is designed to reduce gastric acid and relieve symptoms such as heartburn and indigestion. Experiencing indigestion would be inconsistent with its intended effects and may indicate improper use or another underlying issue. C. "I should take the medication following a meal.": Proton pump inhibitors like lansoprazole work best when taken before meals because this timing enhances absorption and maximizes acid suppression. Taking it after eating may reduce its effectiveness. D. "I should chew the capsule thoroughly.": Lansoprazole capsules are formulated as delayed-release granules that should be swallowed whole to maintain integrity. Chewing them disrupts the protective coating, leading to reduced effectiveness and potential irritation.
