OEC OEC Cardiovascular Emergencies & Shock Management 2

Question 1

Which best defines shock as used in emergency medical care?

Accepted Answer

Inadequate perfusion of tissues causing cellular hypoxia

Answer

Shock is defined as inadequate tissue perfusion that leads to cellular hypoxia and, if untreated, organ failure and death.

Question 2

Which type of shock results from a severe systemic allergic reaction?

Accepted Answer

Anaphylactic shock

Answer

Anaphylactic shock results from massive histamine release during a severe allergic reaction, causing systemic vasodilation and increased vascular permeability.

Question 3

What is the primary field management priority for hypovolemic shock?

Accepted Answer

Control hemorrhage and minimize heat loss to prevent hypothermia

Answer

Controlling the source of hemorrhage and preventing hypothermia are the critical field interventions for hypovolemic shock before transport.

Question 4

Which is an early sign of shock before blood pressure falls?

Accepted Answer

Anxiety and restlessness

Answer

Anxiety and restlessness are early signs of shock caused by the body's catecholamine release in response to decreased tissue perfusion.

Question 5

A patient with a spinal cord injury has warm, flushed skin and bradycardia. Which type of shock is most likely?

Accepted Answer

Neurogenic shock

Answer

Neurogenic shock from spinal cord injury causes loss of sympathetic tone, resulting in vasodilation (warm, flushed skin) and bradycardia rather than tachycardia.
