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?

The scenario requires understanding peptic ulcer disease complications, specifically gastrointestinal bleeding. Nursing knowledge of pathophysiology must be applied to identify signs of occult or overt hemorrhage, such as melena, which indicates an urgent need for medical intervention to prevent hemodynamic instability. Choice A rationale . Weight gain is not a primary indicator of peptic ulcer complications. Instead, weight loss may occur due to pain-related anorexia. Significant gain usually suggests fluid retention or cardiac issues, which are unrelated to gastric mucosal erosion or bleeding. Choice B rationale . Ecchymosis on the abdomen, such as Grey Turner's sign, is typically associated with acute pancreatitis or retroperitoneal hemorrhage. While peptic ulcers cause bleeding, it occurs within the gastrointestinal lumen and does not usually manifest as external abdominal bruising. Choice C rationale . Maroon or red-colored urine, known as hematuria, suggests renal or urinary tract pathology rather than gastric issues. Gastrointestinal bleeding from an ulcer affects stool color or emesis, as the blood travels through the digestive tract rather than the kidneys. Choice D rationale . Dark, tarry, or black stool, known as melena, indicates upper gastrointestinal bleeding. Gastric acid converts hemoglobin into hematin, causing the dark color. Monitoring for this change is critical for early detection of ulcer perforation or significant vascular erosion.
