The nurse is developing a teaching plan for a client with acute gastritis caused by drinking contaminated water. The nurse should emphasize the need to report the onset of which problem?

A. Abdominal cramping: Mild to moderate abdominal cramping is a common symptom of acute gastritis and may not indicate a complication. While it should be monitored, it is not typically an emergency sign. B. Bloody emesis: Vomiting blood may indicate gastrointestinal bleeding, a serious complication of acute gastritis. Immediate reporting is essential to prevent significant blood loss and allow prompt medical intervention. C. Low grade fever: A mild fever can accompany gastritis due to inflammation or infection but is not usually life-threatening. It should be monitored but does not require urgent reporting unless it worsens. D. Bruising of the skin: Easy bruising is not a typical manifestation of gastritis and is not directly related to acute gastrointestinal complications. It may suggest another underlying condition but is not the priority concern for this client.
