Diarrhea, vomiting, and a sunken fontanel could be a sign of dehydration.

• A. Not related
• B. Sign of fever
• C. False
• D. True

Answer: (D)

Dehydration in infants is shown by signs of fluid loss such as vomiting and diarrhea, which deplete body fluids, along with physical signs like a sunken fontanelle. When the fontanelle—the soft spot on a baby's head—appears sunken, it suggests reduced hydration and possible dehydration. This combination is a classic clue that the body is losing more fluids than it’s taking in, so the statement is true. A fever is a separate symptom and doesn’t explain a sunken fontanelle, so it wouldn’t be the right interpretation of these findings. In short, these signs together point to dehydration rather than fever.
