A nurse is reinforcing discharge instructions to a client who has a peptic ulcer. Which of the following information should the nurse reinforce to the client prior to discharge?

A. "Monitor for any changes in the color of your urine such as maroon or red-colored urine.": Hematuria (red urine) is unrelated to upper GI bleeding from peptic ulcers; this is not the correct sign to monitor for GI bleeding. B. "Monitor for the appearance of ecchymosis on the sides of your abdomen/pelvic areas.": Ecchymosis on the flanks (Grey Turner sign) can indicate severe retroperitoneal hemorrhage but is uncommon and not a routine discharge teaching point; also ecchymosis on sides of abdomen is nonspecific. C. "Monitor for any increase or unintentional weight gain.": Weight gain is not a primary concern for peptic ulcer complications; unintentional weight loss would be more relevant. D. "Monitor for any changes in the color of your stool such as dark or black-colored stool.": Dark, tarry stools (melena) indicate upper GI bleeding (digested blood) and should prompt immediate contact with a provider - this is the correct discharge warning sign.
