In assessing dehydration in a child, which question most directly helps gauge hydration status?

• A. Is your child tolerating liquids?
• B. When he/she cries, are there tears present?
• C. How many wet diapers has the child had today?
• D. How many times has your child had diarrhea?

Answer: (C)

Tracking urine output directly reflects hydration status because urine production shows how well the kidneys are receiving and managing fluids. The number of wet diapers in a day provides a practical, quantitative read on whether the child is staying adequately hydrated; more wet diapers generally means better hydration, while a drop in wet diapers signals possible dehydration and the need to reassess fluid intake or rehydration.

Tolerating liquids asks about intake ability rather than actual output. Tear production can lessen with dehydration but isn’t a reliable, quantitative measure, and diarrhea frequency indicates fluid loss but doesn’t tell you the current urine output or hydration level.
