Explanation

Ventricular Fibrillation (VF) is a lethal cardiac arrhythmia where the ventricles quiver instead of pumping, resulting in no cardiac output.
According to Advanced Cardiac Life Support (ACLS) guidelines, the definitive and most critical initial treatment for VF is immediate electrical defibrillation.
In a monitored patient, where the rhythm is identified instantly and a defibrillator is readily available, delivering a shock is the highest priority to restore a perfusing rhythm.
The probability of survival from VF decreases significantly for every minute that defibrillation is delayed.

Option A: While crucial, CPR is initiated to maintain circulation until a defibrillator is ready. In a monitored setting where the defibrillator is immediately available, the priority is to shock first.
Option C: Oxygen is a supportive measure and is administered during resuscitation, but it does not correct the underlying lethal rhythm.
Option D: This action is essential but must not delay immediate, life-saving interventions. The nurse must initiate the emergency response (Code Blue) and start the ACLS protocol first.

Clinical Relevance

Nursing practice connection: Prioritize focused assessment, early escalation, and real-time monitoring when managing ACLS Management of Ventricular Fibrillation (VF) in acute care settings.
Nurses in critical care settings must be able to instantly recognize VF on a monitor and initiate the ACLS protocol without delay, as they are often the first responders at the bedside.
Patient safety depends on regular competency checks and mock code drills to ensure the team can perform high-quality CPR and use a defibrillator effectively and quickly.
What if? If the patient's rhythm was asystole or Pulseless Electrical Activity (PEA) instead of VF, the initial management would be to start high-quality chest compressions immediately, as these are non-shockable rhythms. Defibrillation would be contraindicated.

How to Approach the Question

First, identify the clinical scenario: a patient is on a cardiac monitor, which implies the rhythm is known and emergency equipment is likely available.
Next, identify the specific rhythm: Ventricular Fibrillation (VF). Recall that VF is a lethal, shockable rhythm.
Analyze the question's core ask: 'initial management'. This requires you to prioritize actions based on established emergency protocols (ACLS).
Evaluate the options based on the VF/pVT algorithm. The highest priority for a shockable rhythm is defibrillation.
Rule out secondary or delayed actions. CPR is for when the defibrillator isn't ready, oxygen is supportive, and notifying the doctor shouldn't delay the life-saving intervention.
