Which statement accurately describes reassessment after starting IV fluids in dehydration?

• A. Weight only
• B. Temperature only
• C. Vital signs, capillary refill, urine output, mucous membranes, and weight (as feasible)
• D. Blood pressure only

Answer: (C)

Reassessment after starting IV fluids in dehydration should give a full picture of how the child is responding to therapy by looking at several interconnected signs of perfusion, hydration, and fluid balance. Vital signs track overall stability and how the circulatory system is adapting as volume improves. Capillary refill time is a quick gauge of peripheral perfusion—shorter refill times indicate better blood flow to tissues. Urine output shows whether kidneys are receiving enough perfusion and whether fluid intake is translating into urine, a key signal of adequate rehydration. Moist mucous membranes reflect improved hydration status, and serial weight measurements provide an objective tally of net fluid gain or loss over time, guiding ongoing fluid management. Because each parameter reflects a different aspect of the child’s status, together they offer the most reliable view of rehydration progress. Relying on any single measure, like blood pressure or temperature alone, can miss ongoing dehydration or shifts in fluid balance, whereas a comprehensive assessment helps tailor therapy as the child improves.
