Shock
Topic Description:
Shock is defined as inadequate tissue perfusion. There are four types of shock that emergency nurses
may encounter on the CEN exam: hypovolemic shock, distributive shock, cardiogenic shock and
obstructive shock. This session will focus on the pathophysiology of various shock states as well as
nursing’s role in assessment, interventions and evaluation of care when caring for the patient with
shock.
Objectives:
At the completion of this topic, the participant will be able to:
1. Define shock.
2. Differentiate the signs of compensatory shock from decompensatory shock.
3. List the three forms of distributive shock.

SHOCK
Objectives:
At the completion of this section, the learner will be able to:
• Define shock
• Differentiate the signs of compensatory shock from decompensatory shock
• List the three forms of distributive shock
The CEN exam contains nine questions on shock which involve the following topics:
• Cardiogenic shock
• Distributive shock (e.g. anaphylactic, septic, neurogenic shock)
• Hypovolemic
• Obstructive (e.g. pericardial tamponade, tension pneumothorax)
• Shock (not specific)
Shock (lack of oxygen to the tissues) o Hypovolemic shock – Decreased
cellular perfusion secondary to lack of circulating volume o Cardiogenic
shock – Decreased cellular perfusion secondary to failure of the central pump o
Distributive shock – Decreased cellular perfusion secondary to maldistribution
of the oxygen to the periphery o Obstructive shock – Decreased cellular
perfusion secondary to obstruction of blood into or out of the ventricles (e.g.
pulmonary embolism, pericardial tamponade, tension pneumothorax)
Obstructive shock
