CFA Hemorrhage & Emergency Response 2

Question 1

When managing a patient with suspected internal hemorrhage after blunt abdominal trauma, which finding is MOST indicative of significant blood loss?

Accepted Answer

Tachycardia with hypotension

Answer

Tachycardia combined with hypotension is a classic sign of significant internal blood loss indicating compensatory shock.

Question 2

A patient sustains a femoral artery laceration. After applying direct pressure for 3 minutes, bleeding continues. What is the NEXT appropriate step?

Accepted Answer

Apply a tourniquet proximal to the wound

Answer

A tourniquet placed proximal to an arterial laceration that fails to respond to direct pressure is the correct escalation to control life-threatening extremity hemorrhage.

Question 3

Which class of hemorrhagic shock corresponds to a blood loss of 750–1500 mL in a 70 kg adult?

Accepted Answer

Class II

Answer

Class II hemorrhage represents 15–30% of blood volume loss (approximately 750–1500 mL), typically showing tachycardia but near-normal blood pressure.

Question 4

During a surgical case, the first assistant notices persistent oozing from a small vessel in the wound bed. The MOST appropriate immediate action is to:

Accepted Answer

Apply bipolar electrocautery to the bleeding vessel

Answer

Bipolar electrocautery precisely coagulates small vessels with minimal collateral thermal damage, making it the preferred tool for persistent intraoperative oozing.

Question 5

Which hemostatic agent works by providing a physical scaffold that activates the clotting cascade when applied to a bleeding wound?

Accepted Answer

Oxidized regenerated cellulose

Answer

Oxidized regenerated cellulose (e.g., Surgicel) acts as a physical matrix that promotes platelet aggregation and activates clotting factors at the wound site.
