An athlete is injured on the field his teammates see that the injury is moderately swollen and the athlete reports that the area is numb what's the first thing his teamates should do

I think I would recommend not letting him play. Possibly call 911, or bring him to a hospital.

Keep the athlete steady and give him/her space. most importantly wait for assistance from a medic or trainer to arrive. its not safe for teammates to take actions as they are most likely not properly equipped or trained and can cause further damage.

Ithink it's choice d (antibiotic resistance)
