D) transcutaneous pacing.

Question

Quizplus · Accepted Answer

The most important treatment for pulseless electrical activity (PEA) is to assess for the underlying cause. This involves a thorough history and physical exam, obtaining vital signs and laboratory studies, and performing focused diagnostic tests such as electrocardiography and ultrasound. Treatment will depend on the identified cause, but interventions may include administering medications such as epinephrine or vasopressin, performing cardiopulmonary resuscitation (CPR), and addressing underlying metabolic disturbances. Defibrillation and transcutaneous pacing are not effective in PEA, as there is no mechanical cardiac activity to synchronize. Carotid massage is not indicated in the treatment of PEA and could potentially cause harm.
