Your patient is a 33-year-
old man who has a gunshot wound to his right leg and has active, steady, dark red bleeding. He is
awake, pale, and diaphoretic. He has a strong radial pulse of 112 per minute, a respiratory rate of

Cervical spine immobilization, high-
concentration oxygen, direct pressure, and pressure point compression
High-concentration oxygen, tourniquet, PASG, and elevation of the extremity
Direct pressure, high-concentration oxygen, and splinting the leg - CORRECT ANSWER -
Direct pressure, high-concentration oxygen, and splinting the leg
, Which of the following is recommended in situations in which a tourniquet must be used?

The tourniquet should be at least 2 inches wide.
Commercial tourniquets are preferable to improvised tourniquets.
If possible, the tourniquet should be placed on a joint. - CORRECT ANSWER -
If possible, the tourniquet should be placed on a joint.
Which of the following is the most effective way of controlling external bleeding in superficial wou
nds?
