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: Abdominal cramping can be a common symptom of gastritis and may not necessarily require immediate reporting unless it is severe or accompanied by other concerning symptoms. B. Low grade fever: A low-grade fever can occur with gastritis as part of the inflammatory response, but it is not an immediate concern unless it persists or worsens. It is generally not as urgent as other symptoms. C. Bruising of the skin: Bruising is not a typical symptom of gastritis. It may be indicative of a bleeding disorder or other underlying issues unrelated to the gastrointestinal system. However, it is not directly associated with gastritis. D. Bloody emesis: Bloody emesis (vomiting blood) is a critical sign that indicates possible gastrointestinal bleeding, which can occur with severe gastritis. This is an emergency situation and should be reported immediately as it requires urgent medical attention.
