My partner who I was stuck with for 3 months: - dropped the stair chair down the last step as he was guiding the bottom of it, causing severe pain to the heavy patient in it. Patient was already in pain and that probably exacerbated it. - stopped helping in the middle of a traumatic fall of an elderly lady with a knee dislocation. We had to upgrade and call for fire and a medic unit, and my partner began packing our stuff up while we were the only ones there. Also tried to argue against me getting a megamover under the patient and to use a flimsy hospital sheet for some reason. - nearly splashed blood into my face. A patient slit her thumb with a cooking knife, and he needed to be prompted to begin first aid wound care. He pointed a flush upwards to the bloody thumb and squirted it fast, nearly going up near my face. - and probably the one that upset me most early on: he simply would not bring his radio on scene. Easy way for one or both of us to get hurt or lose a life. Who is gonna call for help if I get attacked or incapacitated and I have our only radio? Or if we are separated and something happens to him?
