Which signs indicate gastroenteritis?

• A. Severe GI pain, forceful vomiting, fever, bloody stool, longer than 48 hours, dehydration
• B. Cough and mild fever
• C. Headache and rash
• D. Nosebleed and earache

Answer: (A)

Gastroenteritis typically presents with stomach and intestinal irritation that leads to vomiting, diarrhea, abdominal cramps, fever, and fluid loss (dehydration). The best choice describes severe GI pain plus forceful vomiting, fever, and dehydration, with bloody stool and symptoms lasting more than 48 hours. These elements reflect the inflammatory and infectious processes in the gut, the potential for a more significant infection if the illness persists, and the risk of dehydration from ongoing fluid loss. Bloody stool can occur with certain bacterial causes of gastroenteritis, signaling a need for medical evaluation in some cases.

The other options don’t fit gastroenteritis: cough with mild fever points to a respiratory infection; headache with rash could indicate a viral or systemic condition not primarily involving the GI tract; nosebleed and earache are unrelated to gut inflammation.
