A student trips and lacerates her forearm during PE. What should a teacher do first after putting on gloves?

Applying a clean bandage and directing pressure to the wound while the student elevates her arm is the most appropriate first action after putting on gloves. This response is crucial for managing bleeding and protecting the wound from infection. By applying pressure to the laceration, the teacher helps to reduce blood flow from the injury site, which is essential in minimizing blood loss and starts the process of clot formation. Elevating the arm can also assist in reducing blood flow to the area, further controlling bleeding.

Immediate action to address the wound not only promotes the student's physical safety but also provides reassurance and support during a potentially distressing situation. It is vital in first aid to control bleeding before moving on to calling for help, assessing the situation more fully, or addressing other symptoms.
