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?

The scenario requires reinforcing teaching for a client prescribed lansoprazole. Knowledge of proton pump inhibitor pharmacology, adverse effect profiles, and proper administration techniques must be applied to ensure therapeutic efficacy, prevent complications, and promote client safety. Choice A rationale Lansoprazole should be taken on an empty stomach, approximately 30 to 60 minutes before a meal. Food delays drug absorption and decreases the suppression of gastric acid production by parietal cell proton pumps. Choice B rationale Proton pump inhibitors increase the risk of Clostridioides difficile-associated diarrhea by altering normal gastrointestinal flora. Clients must report severe, watery diarrhea immediately to evaluate for this infectious superinfection complication. Choice C rationale Lansoprazole capsules contain enteric-coated granules to prevent drug destruction by gastric acid. Chewing or crushing the capsule destroys this protective coating, causing premature drug activation and therapeutic failure. Choice D rationale Lansoprazole suppresses gastric acid secretion to treat gastroesophageal reflux and ulcers. Indigestion is a symptom of the underlying condition being treated, not an expected or benign side effect of this medication.
