Which sign is NOT typically associated with dehydration in a child?

• A. Altered mental status
• B. Easy capillary refill
• C. Dry mucous membranes
• D. Sunken fontanelle

Answer: (B)

In pediatric dehydration, signs reflecting decreased body fluids and poor perfusion are key. Altered mental status can occur when dehydration is severe due to reduced brain perfusion. Dry mucous membranes and a sunken fontanelle are classic outward signs of fluid loss in a child. Capillary refill is a quick check of peripheral perfusion: dehydration typically slows this return, leading to a delayed refill. An easy, rapid capillary refill suggests good perfusion and hydration, so it does not fit dehydration.
