Which symptom involves multiple episodes that are watery?

• A. Vomiting
• B. Nausea
• C. Constipation
• D. Diarrhea

Answer: (D)

The concept here is recognizing diarrhea as the symptom described by multiple episodes of watery stools. Diarrhea means an increased frequency of bowel movements with stools that are loose or watery, often occurring in several episodes within a short period. This matches the description given, making it the best answer.

In contrast, vomiting is the act of expelling stomach contents, not a pattern of stools; nausea is the sensation that you might vomit, not the actual stool form. Constipation involves hard, infrequent stools rather than watery ones. Understanding this helps you quickly link the description to the right term: diarrhea.
