Which of the following is a sign of poor perfusion in a child?

Poor perfusion in a child is indicated by cool extremities and a decreased level of consciousness. When a child is experiencing inadequate blood flow or perfusion, the body may respond by redirecting blood away from the extremities in an effort to preserve vital organ function. This can result in cooler hands and feet. Additionally, a decreased level of consciousness often accompanies poor perfusion because the brain may not be receiving sufficient oxygen-rich blood, leading to altered mental status or unresponsiveness.

The other signs listed are characteristic of adequate perfusion. Bright red skin suggests good blood flow, warm extremities indicate that blood is circulating well, and a strong and regular pulse demonstrates effective heart function and circulation. Understanding these signs is crucial for identifying children in need of immediate medical evaluation and intervention in a pediatric emergency setting.
