A patient is in cardiac arrest. The patient is being resuscitated. The team leader has asked you to administer 200 J of defibrillation. Which of the following is correct?

Appeared in: RML Lucknow - 2021

Explanation

According to Advanced Cardiac Life Support (ACLS) guidelines, chest compressions should be resumed immediately after a defibrillation shock is delivered.
This action is crucial to minimize the 'no-flow' time (the period without chest compressions), which maximizes coronary and cerebral blood flow.
A rhythm and pulse check should only be performed after completing a full 2-minute cycle of CPR following the shock, as the heart is often stunned and needs mechanical support.
The recommended sequence is: Shock -> Immediate CPR (2 minutes) -> Rhythm/Pulse Check.

Option A: Continuing CPR during the delivery of an electrical shock is extremely dangerous and poses a significant risk of electrocution to the rescuer performing compressions.
Option C: This is an outdated practice. Even if the shock successfully terminates the arrhythmia, the heart muscle is often stunned (asystole or PEA) and unable to contract effectively. Immediate CPR provides necessary perfusion.
Option D: This is a major safety violation. Climbing on the bed creates an unstable position for the provider, increasing the risk of falling and accidental contact with the patient during the shock.

Clinical Relevance

Nursing practice connection: Prioritize focused assessment, early escalation, and real-time monitoring when managing ACLS protocol for defibrillation and post-shock care in acute care settings.
High-quality CPR with minimal interruptions is the single most important determinant of survival in cardiac arrest. The 'shock-then-CPR' sequence is a critical component of this principle.
In a real code blue situation, the team leader is responsible for ensuring the entire team follows the correct ACLS sequence and adheres to all safety protocols, such as calling 'All clear'.
What if? If the patient's rhythm was non-shockable (Asystole or Pulseless Electrical Activity - PEA), defibrillation would be contraindicated. The focus would be solely on continuous high-quality CPR and administering medications like epinephrine every 3-5 minutes while searching for reversible causes (the H's and T's).

How to Approach the Question

First, identify the core of the question: It asks for the correct action immediately following defibrillation in an ACLS scenario.
Next, recall the two main principles of resuscitation: ensuring high-quality CPR with minimal interruptions and maintaining safety for the resuscitation team.
Evaluate each option against these principles. Options involving a rescuer touching the patient during the shock (A) or being in an unsafe position (D) are clear safety violations and can be eliminated immediately.
Between the remaining options (B and C), consider the goal of minimizing 'no-flow' time. Modern ACLS guidelines prioritize immediate resumption of compressions over an immediate rhythm check to improve perfusion to the stunned heart.
Therefore, resuming CPR immediately is the correct action, while checking the rhythm immediately is an outdated and less effective step.
