In a child with pneumonia, which sign suggests the need for intravenous hydration?

• A. Vomiting with inability to tolerate oral fluids
• B. Spaghetti cough
• C. Mild fever
• D. Normal appetite

Answer: (A)

The important concept here is hydration assessment in a child with pneumonia. If vomiting prevents the child from tolerating oral fluids, oral rehydration becomes unreliable and there is a real risk of dehydration. In that situation, giving fluids intravenously ensures reliable replacement of water and electrolytes, maintains tissue perfusion, and supports recovery while the infection is treated. Fever and infection can raise fluid losses, but they alone don’t indicate the need for IV fluids; a normal appetite or only a mild fever also does not signal dehydration. The sign described—vomiting with an inability to tolerate oral fluids—directly points to insufficient oral intake and the need for IV hydration.
