Question

After defibrillation, the advanced cardiac life support (ACLS) nurse says that the patient has pulseless electrical activity (PEA). What is most important for the nurse to understand about this rhythm? a. The heart rate is 40 to $60 \mathrm{bpm}$. b. Hypoxemia and hypervolemia are common with PEA. c. There is dissociated activity of the ventricle and atrium. d. There is electrical activity with no mechanical response.

Step 1

PEA is a condition where there is electrical activity in the heart, but it does not result in a palpable pulse or effective cardiac output. This means that although there is electrical activity, the heart is not effectively pumping blood to the body. Now, let's Show more…

Key Concepts

Pulseless Electrical Activity (PEA)

PEA is a cardiac arrest rhythm where there is identifiable electrical activity on the monitor, but it does not result in any effective mechanical contraction of the heart, meaning no palpable pulse is produced. It highlights the dissociation between the electrical impulses and the mechanical performance of the heart, which is crucial for understanding emergency treatment protocols in cardiac arrest situations.

Advanced Cardiac Life Support (ACLS)

ACLS is a set of clinical guidelines and algorithms used by healthcare providers to manage cardiovascular emergencies, including various cardiac arrest rhythms and arrhythmias. It emphasizes rapid assessment, early initiation of high-quality cardiopulmonary resuscitation (CPR), management of reversible causes, and appropriate interventions based on the specific cardiac rhythm identified.
