Which of the following can indicate the presence of gastroenteritis?

The presence of gastroenteritis is typically indicated by gastrointestinal symptoms, and abdominal pain along with fever are commonly associated findings. Gastroenteritis, often caused by viral or bacterial infections, leads to inflammation of the stomach and intestines, which manifests as abdominal discomfort or cramping. Additionally, fever is a common response to infection as the body works to fight off the invading pathogens.

While each of the other choices presents symptoms, they relate to different conditions. Joint swelling and pain might indicate issues such as arthritis or an autoimmune disorder. Vision changes and dizziness could be linked to neurological issues or systemic illnesses unrelated to gastroenteritis. Coughing and sneezing are primarily respiratory symptoms, which do not align with the typical presentations of gastroenteritis. Thus, the combination of abdominal pain and fever directly correlates with the diagnosis of gastroenteritis.
