Question 1

What type of bleeding is characterized by bright red blood that spurts with each heartbeat?

Accepted Answer

Arterial bleeding. It is the most serious and difficult to control because it comes from a damaged artery under high pressure.

Question 2

What color and flow pattern distinguishes venous bleeding from arterial bleeding?

Accepted Answer

Venous blood is dark red and flows in a steady stream rather than spurting, because veins carry blood at lower pressure than arteries.

Question 3

Which class of hemorrhage involves a blood loss of 30–40% of total blood volume and is characterized by marked tachycardia, hypotension, and altered mental status?

Accepted Answer

Class III hemorrhage. At this level the body's compensatory mechanisms begin to fail, producing hypotension and significant changes in mental status.

Question 4

What is the first and preferred method of controlling external hemorrhage for an EMT?

Accepted Answer

Direct pressure applied to the wound. Firm, continuous pressure over the bleeding site is the most effective and safest first-line intervention.

Question 5

When should a tourniquet be applied for extremity hemorrhage?

Accepted Answer

When direct pressure fails to control life-threatening extremity bleeding, or when direct pressure cannot be applied (e.g., amputation, multiple casualties). It should be placed 2–3 inches proximal to the wound.
