A nurse is teaching a client who has a new prescription for cimetidine to treat peptic ulcer disease. Which of the following statements by the client indicates an understanding of the teaching? (Select all that apply.)

A. "I will take this medication when I need it for pain.": Cimetidine is taken regularly to reduce stomach acid production and promote healing of peptic ulcers. The client should follow the prescribed dosing schedule rather than taking it only when experiencing pain. B. "I should expect my stools to turn black.": Black stools are more commonly associated with iron supplements or bleeding in the gastrointestinal tract, not with cimetidine. The client should report black stools to a healthcare provider, as this could indicate GI bleeding. C. "I can take this medication with or without food.": Cimetidine can be taken with or without food, although taking it with food may help prevent gastrointestinal upset. It does not need to be taken strictly with food. D. "I will eat five small meals each day.": This is beneficial for managing peptic ulcer disease. Eating smaller, more frequent meals can help reduce acid production and prevent irritation of the ulcer. E. "I will take this medication with an antacid.": Antacids should not be taken at the same time as cimetidine because they can interfere with the absorption of the medication. Cimetidine works best when taken separately from antacids. F. "I will take this medication in the morning.": Cimetidine is usually taken multiple times a day (typically once in the morning and once at night), depending on the prescription. It is not necessary to take it only in the morning, and the client should follow the prescribed schedule.
