在一次郊游中某同学不慎摔伤，擦破了点皮，伤口布满血丝。你认为应首先采用哪种措施救护（      ）                   

A

    Shanghai's Maglev Train(磁悬浮列车) runs from Longyang to Pudong International Airport(国际机场). The whole trip takes about 8 minutes.

    Children at or under 120 cm tall don't need to buy tickets to take the train, but they cannot take the train by themselves. Children above 124 cm must buy a full-price ticket.

    If you buy a round ticket, you can get on the train at Longyang Road Station or Pudong Airport Station, and get off at the other station. The return part of the ticket must be used on the same day.
