Correct Answer is A

Explanation

A. Fluid resuscitation

Burns covering a large TBSA result in massive fluid loss due to increased capillary permeability, leading to hypovolemic shock. Fluid resuscitation with lactated Ringer’s solution using the Parkland formula is the priority to restore intravascular volume and prevent organ failure.

B. Transfer to a burn center

While this patient requires specialized burn care, the immediate priority is fluid resuscitation. After initial stabilization, transfer to a burn center can be arranged.

C. Application of sterile dressings

Wound care is important, but it is not the priority in the emergent phase. Restoring circulation and preventing shock take precedence.

D. Administer morphine 8 mg IV

Pain management is crucial, but it is secondary to restoring intravascular volume and preventing hypovolemic shock.

A. D-dimer, fibrinogen and fibrin degradation products. B. Fibrin degradation products lactic acid, and complete blood count. C. Complete blood count platelets and prothrombin time. D. Prothrombin time, form level and dimer

Correct Answer is A

Explanation

A. D-dimer, fibrinogen, and fibrin degradation products is correct because these tests reflect the excessive clotting and fibrinolysis seen in DIC: D-dimer: Elevated due to fibrin breakdown. Fibrinogen: Decreased due to excessive consumption. Fibrin degradation products (FDPs): Increased due to breakdown of fibrin clots.

B. Fibrin degradation products, lactic acid, and complete blood count is incorrect because lactic acid is more useful in sepsis evaluation, not DIC diagnosis.

C. Complete blood count, platelets, and prothrombin time is incorrect because while platelets may be low and PT may be prolonged, these tests alone are not specific for DIC.

D. Prothrombin time, form level, and d-dimer is incorrect because “form level” is not a relevant test, and PT alone is not sufficient for DIC diagnosis.
