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. Bruising of the skin is not typically associated with acute gastritis caused by contaminated water. While bruising may be a sign of other medical conditions or complications, it is not directly related to gastritis. B. Low-grade fever can be a symptom of gastritis, especially if it is caused by an infectious agent. However, it is not typically a severe or emergent symptom that requires immediate reporting unless it is accompanied by other concerning symptoms. C. Abdominal cramping is a common symptom of gastritis and may occur due to inflammation of the stomach lining. While it should be monitored, it is not as concerning as the potential complication indicated by option D. D. Bloody emesis (vomiting blood) is a serious symptom that can indicate severe gastritis or complications such as gastrointestinal bleeding. It is essential to report this symptom promptly as it may require immediate medical attention and intervention.
