What indicates successful rehydration in dehydration?

• A. Worsening dehydration signs
• B. Improved perfusion signs, stable vitals, good capillary refill, and adequate urine output
• C. Persistent dehydration signs
• D. Hypotension with delayed cap refill

Answer: (B)

Successful rehydration means restoring circulating volume enough that tissue perfusion returns toward normal and the kidneys begin to function adequately. When this happens, you typically see vital signs stabilize, perfusion improves (capillary refill returns to normal), and urine output becomes adequate. These indicators show the fluids have effectively increased intravascular volume and improved organ perfusion. In contrast, signs of ongoing dehydration—worsening signs, persistent dehydration findings, or hypotension with delayed cap refill—signal that rehydration is not yet effective and more fluid therapy is needed.
