Correct answer: C — Consider fibrinolysis during ALS for suspected massive pulmonary embolism

Massive pulmonary embolism is a potentially reversible cause of PEA arrest, and fibrinolysis may be considered during resuscitation where suspicion is high and bleeding risk acceptable. PEA is not treated by defibrillation. Amiodarone is not a treatment for obstructive shock from PE. The pearl is that the 4Hs and 4Ts should lead to specific actions, not merely be recited.
