The purpose of defibrillation is to:

Which statement best describes cardiogenic shock?
 Aggressive fluid therapy is always indicated for cardiogenic shock.
 Increased blood pressure with wide pulse pressures always indicates cardiogenic shock.

Which statement regarding compensated versus hypotensive shock is correct?
 A child with shock is always hypotensive.

 An individual in PEA has a detectable pulse.
 PEA always converts to asystole.

 An individual in PEA has no electrical activity.

When should vasopressors be administered during the management of septic shock?

Which statement regarding distributive shock is NOT true?
 Distributive shock can be characterized as either warm shock or cold s
 Distributive shock commonly results in inadequate tissue perfusion and oxygenation.

Which statement about sinus bradycardia is correct?
 Sinus bradycardia is never a normal rhythm.
 *Sinus bradycardia may be an abnormal heart rate resulting from a pathological condition.
 Sinus bradycardia always originates at the AV node.
