Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A patient sustaining a trauma is at risk for excess blood loss. Which protective mechanism is activated to prevent excess blood loss?
A
To prevent this, the body has a thrombolytic (fibrinolytic) mechanism that eventually dissolves clots formed within blood vessels.
B
Excessive clotting is equally dangerous, because it can obstruct blood flow to vital tissues.
C
An intricate clotting mechanism is activated when necessary to seal any leak in the blood vessels. Excessive clotting is equally dangerous, because it can obstruct blood flow to vital tissues.

D

Explanation: 

Detailed explanation-1: -Trauma-induced coagulopathy is coagulopathy caused by the trauma itself. The pathophysiology of trauma-induced coagulopathy consists of coagulation activation, hyperfibrino(geno)lysis, and consumption coagulopathy. These pathophysiological mechanisms are the characteristics to DIC with the fibrinolytic phenotype.

Detailed explanation-2: -Indeed, elevation of factor VIII activity seems to be the most robust effect of severe multiple trauma in terms of clotting factor activities. A possible explanation is the known role of factor VIII as an acute phase protein [28].

Detailed explanation-3: -The treatment of trauma-related bleeding starts at the site of the accident with compression, tourniquets, and a pelvic binder to prevent further blood loss, followed by rapid transport to a certified trauma center.

Detailed explanation-4: -Although there are several different mechanisms of injury, trauma can be categorized broadly into three groups: penetrating, blunt, and deceleration trauma. There is a significant overlap in the causes, outcomes, and body’s response to the different injury types.
