What is the normal capillary refill time in children?

Correct option is B

The normal capillary refill time (CRT) in children is less than 3 seconds. It is a quick clinical test used to assess blood circulation and dehydration. A prolonged capillary refill time (more than 3 seconds) may indicate shock, poor circulation, or dehydration, requiring immediate medical attention.
Explanation of Each Option:
· Less than 1 second: May be normal in some cases but is not the standard clinical reference for capillary refill time.
· Less than 3 seconds: Correct answer; a normal CRT indicates good blood circulation and hydration. If CRT is prolonged, it suggests shock or poor perfusion.
· 5 seconds: Indicates delayed capillary refill, which may be a sign of dehydration or circulatory failure.
· 7 seconds: Severely prolonged CRT suggests critical circulatory impairment, requiring immediate medical intervention.
