You are treating a young male with an arterial hemorrhage from a large laceration to his inner arm. Despite direct pressure with a sterile dressing, the wound continues to bleed heavily. You should:

a) Apply a tourniquet proximal to the bleeding wound, if feasible, and continue to apply direct pressure
b) Elevate the arm above heart level and continue applying direct pressure on the bleeding site
c) Apply additional dressings and increase the pressure directly over the bleeding site
d) Apply pressure to the brachial artery in the upper arm while continuing to maintain direct pressure on the wound
