Intro: Hemorrhage Control and Shock Management

What is the correct first step in controlling severe external bleeding from an extremity?

• Apply direct pressure to the wound

• Apply a tourniquet above the wound

• Pack the wound with hemostatic gauze

• Secure a pressure bandage over the site

Answer explanation

Direct pressure is always the first step in hemorrhage control. Tourniquets and hemostatic dressings are escalation steps used only when direct pressure fails.

A tourniquet is most appropriate for which situation?

• Uncontrolled, life-threatening limb bleeding

• Minor limb bleeding controlled by pressure

• Internal bleeding after blunt abdominal trauma

• Slow venous ooze from a scalp laceration

Answer explanation

Tourniquets are indicated for life-threatening extremity bleeding that direct pressure cannot control. They cannot address internal or non-extremity bleeding.

Which finding is most characteristic of compensated shock?

• Tachycardia with pale, cool, diaphoretic skin

• Bradycardia with a widening pulse pressure

• Flushed, warm, dry skin with low heart rate

• Hypotension with altered mental status present

Answer explanation

Compensated shock features tachycardia and pale, cool, diaphoretic skin as the body works to maintain blood pressure. Hypotension and altered mental status indicate decompensated shock.

How does decompensated shock differ from compensated shock?

• Hypotension and altered mental status are present

• Only a narrowing pulse pressure is observed

• The condition resolves without treatment in most cases

• Tachycardia appears; compensated shock has none

Answer explanation

Decompensated shock occurs when the body can no longer maintain blood pressure, causing hypotension and altered mental status. Compensated shock still maintains blood pressure despite tachycardia and skin changes.

Which finding best distinguishes neurogenic shock from hypovolemic shock?

• Warm, dry skin with slow or normal heart rate

• Pale, cool skin with a rapid, weak pulse

• Altered mental status with low blood pressure

• Tachycardia with a narrowing pulse pressure

Answer explanation

Neurogenic shock causes loss of sympathetic tone, producing warm, dry skin and bradycardia. Hypovolemic shock produces the opposite: pale, cool, diaphoretic skin and tachycardia.

A patient in anaphylactic shock most likely presents with which finding?

• Fever, altered mental status, and suspected infection source

• Pale, cool skin and recent large blood loss

• Urticaria, wheezing, and hypotension after an exposure

• Distended neck veins and muffled heart sounds

Answer explanation

Anaphylactic shock is a distributive shock triggered by an allergen, presenting with hives, wheezing, and hypotension. Distended neck veins suggest obstructive shock, not anaphylaxis.

Which intervention is the highest priority when managing a patient in hemorrhagic shock in the field?

• Control bleeding and transport rapidly to definitive care

• Give high-flow oxygen and maintain patient warmth

• Elevate the legs and monitor vitals frequently

• Position supine and establish intravenous access first

Answer explanation

Hemorrhagic shock requires stopping the bleeding and rapid transport because definitive surgical care cannot be replicated in the field. Oxygen and warmth are supportive but do not address the cause.

Why is preserving body warmth important when managing a shock patient?

• Hypothermia impairs clotting and worsens shock outcomes

• Warmth directly prevents decompensated shock progression

• Warmth reduces supplemental oxygen needs during transport

• Warmth raises blood pressure via peripheral vasodilation

Answer explanation

Hypothermia disrupts clotting function, which worsens bleeding and shock. Keeping a shock patient warm preserves the body's ability to form clots and limits further deterioration.
