What is the priority intervention for a patient in ventricular fibrillation?
A
Administering oxygen
B
Defibrillation
C
Performing a 12-lead ECG
D
Starting an IV line
Verified step by step guidance1
Understand the condition: Ventricular fibrillation is a life-threatening heart rhythm that results in the heart being unable to pump blood effectively. It requires immediate intervention.
Identify the primary goal: The priority in ventricular fibrillation is to restore a normal heart rhythm as quickly as possible to prevent cardiac arrest and ensure blood circulation.
Evaluate the interventions: Consider the options provided: administering oxygen, defibrillation, performing a 12-lead ECG, and starting an IV line.
Determine the most effective intervention: Defibrillation is the most effective and immediate intervention for ventricular fibrillation as it can restore normal heart rhythm.
Prioritize actions: While other interventions like administering oxygen and starting an IV line are important, they do not directly address the immediate need to correct the heart rhythm. Therefore, defibrillation should be prioritized.
