lets say in theory you have a patient who has suffered some major trauma (car accident) and on scene you have her kid who is hysterical, balling etc. Obviously you can't tell him it will all be okay, but what do you say to him? Or a situation where someone who has been moderately injured is screaming, crying etc and it is spiking her BP/heart rate and making her worse. How can we as EMTs be more reassuring, and get patients to trust us more?
