小张运动时上臂受伤,从受伤流出血液较多,呈暗红色,血流速度较缓慢。此时止血的正确方法是

A.在伤口上贴创可贴  

B.在伤口的近心端,用指压止血法或止血带止血

C.让血液自然凝固   

D.在伤口的远心端,用指压止血法或止血带止血

答案

答案:D

动脉出血的特点,颜色鲜红,血流较快,常呈喷射状;静脉出血的特点是静脉血色暗红,血流较缓;毛细血管出血,血液缓慢渗出.动脉是把血液从心脏送往全身各处,血液流动方向是心脏→动脉;静脉是把全身各处的血液送回心脏的血管,静脉的血液流动的方向是心脏←静脉.因此,大静脉受伤出血时,正确的急救方法是采用指压法(或止血带)远心端止血;动脉出血在近心端止血;毛细血管出血可以自然止血,也可以用干净纱布包扎伤口.小张受伤流出血液较多,血色暗红,血流较缓.因此判断是静脉出血.故应首先采用指压法(或止血带)远心端止血,同时紧急拨打120送医院.

故选:D.
