A nurse is teaching a client about the importance of early defibrillation in BLS. What is the rationale for early defibrillation?

A.

"Early defibrillation is necessary to relieve pain and discomfort during cardiac arrest."

B.

"Defibrillation is the primary intervention to restore a normal heart rhythm during BLS."

C.

"Early defibrillation helps to assess the client's response to BLS interventions."

D.

"Defibrillation is only appropriate for specific cardiac rhythms and should not be used in most cases."

Answer and Explanation

The Correct Answer is B

A) Incorrect. Defibrillation is not used to relieve pain and discomfort during cardiac arrest. Its primary purpose is to restore a normal heart rhythm.

B) Correct. Early defibrillation is crucial in BLS because it is the most effective intervention to restore a normal heart rhythm during cardiac arrest. It involves delivering an electric shock to the heart to stop chaotic rhythms like ventricular fibrillation and allow the heart's natural pacemaker to regain control.

C) Incorrect. Early defibrillation is not used to assess the client's response to BLS interventions. It is a time-sensitive intervention aimed at restoring a viable heart rhythm.

D) Incorrect. Defibrillation is appropriate for specific cardiac rhythms, especially ventricular fibrillation and pulseless ventricular tachycardia. In these cases, early defibrillation is vital. Delaying defibrillation can significantly decrease the chances of successful resuscitation.

B) Incorrect. This client's statement indicates knowledge of the need to initiate chest compressions promptly if a person is unresponsive and not breathing.

C) Correct. Performing a thorough physical examination is not recommended in cardiac arrest situations, as it may delay life-saving interventions like chest compressions and rescue breaths.

D) Incorrect. This client's statement reflects an understanding of the significance of early recognition in improving survival rates during cardiac arrest.

Correct Answer is A

Explanation

A) Correct. CPR is a life-saving technique used to restore circulation and maintain oxygenation in individuals who have experienced cardiac arrest or have stopped breathing. It involves chest compressions to manually pump blood and provide oxygen to vital organs.

B) Incorrect. CPR is not intended to stop all heart rhythms; rather, it aims to keep blood flowing to vital organs until more advanced medical assistance can be provided.

C) Incorrect. CPR is a critical intervention for severe emergencies like cardiac arrest and is not limited to treating minor heart conditions.

D) Incorrect. While CPR is crucial in the immediate response to cardiac arrest, it is not a substitute for professional medical care. Timely activation of emergency medical services is essential to ensure the best possible outcome.
